The word arteriovenous refers to the type of body connection between arteries and veins in which a vein is drained by one artery. This connection is more common in animals than it is in humans, but it does happen every time you get a cut or scrape on your skin and blood seeps out; this is an example of arteriovenous drainage. Arteriovenous can be used as an adjective or noun. For instance, if we were talking about the heart—the venae cavae are connected to the right ventricle through intact semilunar valves and provide oxygenated blood from the lungs for distribution throughout the body via systemic circulation. Arteriovenous is also used as a term to refer to the physical state of an organ’s blood vessels, particularly veins. If left untreated, arteriovenous could lead to dangerous conditions such as pulmonary edema and hemorrhage. That is why it’s important to visit a doctor for Arteriovenous in Singapore. Blood vessels are part of our circulatory system which transport blood throughout our body at speeds of about five feet per second. Arteries carry deoxygenated blood away from the heart while veins return oxygenated blood back to it after delivering nutrients and oxygen to organs and tissues. The human cardiovascular system has three different sections: pulmonary circulation, systemic circulation, and the heart—the centerpiece required for both sections. The vascular tone within these sections can be altered by certain things. For example, carbon monoxide can cause vasoconstriction, but it is also reversible. Arteriovenous has more to do with the physical state of blood vessels rather than how they are altered by specific chemicals. Some treatments for Arteriovenous in Singapore include aspirating the blood from the vein by puncturing it with a hollow needle attached to a syringe before removing any clots or obstructions which may be present in the vessel. This process is known as venipuncture and usually only lasts 30 seconds or so before blood flows through on its own again. While humans have this connection between arteries and veins, it doesn’t become noticeable until someone experiences an injury that allows direct injection of air into a vein—which basically never happens because the skin is so good at protecting our bodies. When this happens, it is called an arteriovenous fistula and can be very dangerous if not treated by a professional right away. Arteriovenous isn’t something that needs to be worried about unless someone has an injury that allows air into the veins—other than that, there is no need to worry about whether your blood vessels are an arteriovenous connection or not! However, if you find yourself with an arteriovenous condition it may be nothing serious and will fade away as quickly as it appeared. But there are some cases when this particular connection can become life-threatening, visit your doctor for Arteriovenous in Singapore. Here’s how to recognize the signs: If you notice any bulging, particularly near your ankles or calves; that could mean that your legs have become larger due to a buildup of blood. If you see a bluish-colored vein running down the center of your body, particularly if it is swollen and tender to touch, there’s a good chance that you have an arteriovenous connection. When your skin becomes pale or red near the bulging veins, even though it may just be temporary, then this could also indicate that you might have an arteriovenous condition. If you notice any swelling in one limb accompanied by discoloration, numbness, or pain then these too are signs that something serious may be going on with your circulatory system. In many cases, varicose veins can become a symptom of a more serious medical issue such as deep vein thrombosis so if your doctor suspects that is what you have then they may do a blood test. Typically, the only reason a person would need to see a doctor for Arteriovenous in Singapore is if it starts to become painful or causes any type of swelling. However, there are some cases when it could be life-threatening. If the leg is not properly drained and builds up too much blood pressure can cause ruptures in the veins and arteries which will lead to swelling of tissues outside the legs as well as within the pelvis which can become quite painful. In this case, surgery is required immediately to prevent blood from building up or your tissue from dying due to lack of oxygen supply. If you suspect that you have an arteriovenous condition then the best thing to do is consult with your doctor for Arteriovenous in Singapore as soon as possible. Your doctor may order blood tests, x-rays, an MRI, or an ultrasound scan. It’s also important to tell your family so they know what signs to look for should any serious symptoms arise. Because arteriovenous connections are not common in people there isn’t a lot of research being done but early detection is key so getting checked out by a medical professional can prevent it from becoming more problematic.
The term “atherosclerosis” comes from the Greek words ‘athreos’ and ‘sclerosis’, which together mean “hardness of the arteries”. In this condition, a blood clot containing cholesterol and other fats or cells will form on the artery wall. This can slowly make it narrower over time. Arteries are vessels that carry blood from your heart to the rest of your body. They have a thin layer of cells lining their outer walls, allowing oxygen-rich blood to flow through them easily. Atherosclerotic plaque formation gradually narrows these pathways until they become restricted, resulting in temporary or permanent impairment of function. That’s why you need to visit a doctor for Atherosclerosis in Singapore. Depending on where it forms, narrowing caused by atherosclerosis may affect blood flow to various organs. The heart, brain, and legs are the most commonly affected in atherosclerosis. Atherosclerosis is generally caused by fatty materials like cholesterol getting deposited into your arteries (known as “plaque”). This plaque formation can result in restricted blood flow due to arterial narrowing or complete blockage of a blood vessel. Factors that increase your risk of developing this condition include Family history. People with atherosclerosis within their families have a higher risk of developing it themselves. This may be because some hereditary conditions can cause abnormalities in the lining of artery walls. Elevated LDL levels. High levels of cholesterol-carrying low-density lipoprotein (LDs) contribute to plaque buildup and may increase your risk of atherosclerosis. Poor diet. Consuming foods high in fat and cholesterol can cause LDL particles to become more likely to deposit into arterial walls. Obesity. Carrying excess weight can cause cholesterol levels to rise, as well as increase the overall amount of fatty material that is available for deposits. Lack of exercise leads to obesity and elevated cholesterol levels, both of which increase your chances of developing atherosclerosis. Unhealthy lifestyle choices like smoking and drinking also play a role (for example atherosclerosis rates are higher among smokers). Hereditary factors can make you more likely to develop this condition if you don’t maintain a healthy lifestyle, visit a doctor for Atherosclerosis in Singapore. However, it’s important not to neglect your health, even if you think that atherosclerosis may run in your family. There are several different types of atherosclerosis, which often affect people differently and at different rates. The main symptom is usually a type of chest pain known as angina pectoris; however, some other possible signs include Sharp or cramping pains in one or both arms. This could indicate insufficient blood flow to the limbs for proper nourishment. If left untreated, this condition can lead to muscle damage and death of tissue (known as “gangrene”). Chest pain upon exercise. When plaque begins obstructing arteries carrying oxygen-rich blood to your heart muscles, you may feel severe pain during cardiovascular activity, such as running or swimming. Numbness or weakness in one side of the body. Symptoms may indicate an impaired blood supply to your brain. Like chest pain, this can result in permanent damage if left untreated, visit a doctor for Atherosclerosis in Singapore. There are other possible symptoms that affect your legs and feet instead of your heart or brain. These include chronic fatigue. Created by lack of oxygen supply due to narrowed arteries. Swelling in lower extremities. This is known as “peripheral edema”, which causes tissues to become waterlogged with excess fluid, making them puff up when you stand or walk around too much. Ankle joint damage. Due to atherosclerosis restricting nourishment through the arteries, muscle tissues surrounding the ankle joints may die off (known as “peroneal muscle atrophy”). Pain in lower legs. Caused by the buildup of plaque and calcium within your arteries. The most serious complications that can occur if atherosclerosis goes untreated are heart attack (myocardial infarction) or stroke. These conditions result from the blood supply to an area of the heart or brain becoming severely reduced due to complete blockage, triggering the death of tissue (infarction). Atherosclerosis is not only a risk factor for these conditions, but also increases your chance of survival after suffering one, visit a doctor for Atherosclerosis in Singapore. To avoid contracting or causing this condition, you should take steps to protect your arteries by leading a healthy lifestyle and following medical advice. Stay informed about the latest treatments for this condition, visit a doctor for Atherosclerosis in Singapore. Talk with your doctor about ways to prevent further damage to your blood vessels, such as quitting smoking if you smoke, eating healthier food options (rich in anti-oxidants), exercising more often, and maintaining a healthy weight. Make sure that you have regular checkups so your doctor can monitor your heart health.

The aorta is the largest artery in the human body. It carries blood from the heart to other parts of the body, and it is essential for delivering oxygen and nutrients to all tissues. Aortic aneurysms are a serious condition in which the aorta balloons or bulges out. If left untreated, an aortic aneurysm can rupture and cause death. With treatment from doctors for the aorta in Singapore, patients have a higher chance of living when the condition is caught early. Adult patients who have a family history of aortic aneurysms may be at increased risk for the condition, and they should consider genetic counselling to determine whether or not it is advisable for them to obtain yearly abdominal ultrasounds. At-risk patients who sustain minor injuries such as those that occur during routine activities such as climbing up stairs or even bending over should seek prompt medical attention because these seemingly benign actions can cause damage to the wall of the aorta that can lead to the aneurysmal formation. The aneurysm is allowed to progress untreated, it can eventually rupture and cause death. A ruptured aortic aneurysm causes extremely rapid exsanguination that leads to death in as little as just one or two minutes. Any patient who experiences pain in the chest following an injury should be taken immediately to the emergency room for evaluation; adult patients who sustained minor injuries such as those that occur during routine activities such as climbing stairs or even bending over should seek prompt medical attention because these seemingly benign actions can cause damage to the wall of the aorta that can lead to the aneurysmal formation. There are several treatment options available including stenting, endovascular coiling, open surgical repair, or watchful waiting. Causes of aortic aneurysms include high blood pressure, atherosclerosis, chronic inflammatory diseases such as syphilis or Kawasaki disease, and connective tissue disorders such as Ehlers Danlos Syndrome (which affects collagen production). Some patients with Turner syndrome may be born with weakened walls in their aortas that predispose them to aortic aneurysm formation later in life. Aneurysms tend to occur over time and grow slowly; most people do not know they have them until they experience symptoms such as pain in the chest following an injury. Aneurysms are most commonly located in the abdomen or in the chest but can develop anywhere in the body, including the brain and limbs. A common sign of such an expansion (and potential rupture) is sudden severe chest pain on one side of the body. Other symptoms include fainting, shortness of breath, nausea, vomiting, and coughing up blood. If any of these symptoms occur after physical activity – including exercise, sexual intercourse, or coughs it’s important to go see a doctor for the aorta in Singapore immediately. While the exact cause of an aortic aneurysm is unknown, people who smoke and/or have high blood pressure are more likely to develop one. This condition is quite rare in young people but becomes increasingly common when people get into their 40s or 50s. Around 15 percent of all people with abdominal aortic aneurysms die within 30 days if they don’t receive treatment. If it ruptures, less than half of those affected by the rupture will survive the first day; however, 90 percent die within two weeks (without receiving treatment). The five-year survival rate for this condition is only about 50 percent without surgical repair (which involves removing the weakened section of the artery and replacing it with a synthetic tube). High-quality doctors for the aorta in Singapore are readily available in Pan Asia. People who have an abdominal aorta that’s bulging, but not yet ruptured, can sometimes benefit from wearing compression stockings to reduce pressure on the area. In most cases of rupture, surgery is necessary, and it has been shown to decrease mortality rates by 50 percent or more. Doctors at Pan Asia treat an aortic aneurysm with medication for high blood pressure and/or smoking cessation as well as increasing fibre in their diets and encouraging regular exercise. Doctors for the aorta in Singapore can help you treat. The patient is administered general anaesthesia, which makes the patient sleep through the entire procedure. During this time, special monitoring devices are attached to the patient (for example, ECGs and pulse oximeters) to monitor their condition throughout the surgery. Dialysis is a medical procedure where the kidney is artificially removed from the body and replaced with a machine. It can be used to cleanse the body of toxins that are produced as a result of certain diseases and conditions, such as chronic kidney disease. Chronic kidney disease is a condition that affects millions of people all over the world. Unfortunately, many people who have it don’t even know they have it until it’s too late. This is because early symptoms often go unnoticed or are mistaken for something else. Dialysis is an effective method that can slow down the damage of chronic kidney disease; however, it cannot prevent further deterioration of the kidneys. If you are experiencing any symptoms, please speak with your doctor for dialysis in Singapore to determine whether or not dialysis treatment could be right for you. Dialysis can be very effective for certain types of kidney disease, but it is not the best long-term solution. If you have chronic kidney disease and are experiencing symptoms, please speak with our doctors for dialysis in Singapore to determine whether or not dialysis treatment could benefit you. There are many different methods that can be used when performing hemodialysis. Some of these methods include the following: Fistula method, Dialyzer method, and Cuffed tunneled catheter method. Dialysis treatments typically last between four to five hours, depending on which type of treatment is being administered. They take place at a dialysis center several times per week over the course of several months. During dialysis, a patient’s blood is sent to the machine and then returned back to the body. The two common types of dialysis treatment are hemodialysis and peritoneal dialysis. Hemodialysis uses a machine that filters toxins out of the blood through an artificial kidney outside of the body. Peritoneal dialysis allows toxins to be removed by passing fluids into your stomach cavity where they are absorbed into your bloodstream. Many people think that their lives will end after being diagnosed with chronic kidney disease because it’s something you can never recover from. However, if you receive proper medical care including dialysis treatment, you can go on to live a full life despite having this condition. Dialysis in Singapore can help a patient feel better, especially in the future when new forms of treatment become available. Dialysis is not a cure but it can be an effective method for temporarily treating chronic kidney disease to improve certain symptoms and postpone the need for a kidney transplant. Dialysis is a procedure that has come a long way since it was first introduced in its current form. It used to only be able to support patients with this condition for short periods of time; now, many people are able to perform dialysis multiple times per week over several months at a time. This allows them more freedom and helps them live full lives despite having chronic kidney disease. High-quality doctors for dialysis in Singapore can help provide the best possible care and support for patients with chronic kidney disease. Dialysis is the removal of excess fluid(s) from your body. The second benefit is that some medications are removed more efficiently through dialysis than through other means. Dialysis for some people is fewer or less severe headaches, sometimes even eliminating them entirely since they may be caused by low blood pressure due to dehydration (loss of water), which can also lead to fainting and fatigue. Dialysis in Singapore ensures that you receive enough liquids and salt/electrolytes in balance – these elements are crucial for keeping your blood at the proper viscosity (thickness). Dialysis does not cure kidney disease but it can prevent further damage to kidneys; therefore, it can help people to live longer. It is that most patients are able to return to the lifestyle they had before kidney disease developed. Dialysis treatments require access to a specialized doctor for dialysis in Singapore that can perform the blood purification process necessary to remove the toxic wastes from the body. A dialysis patient who has been on Dialysis for some time would have been so used to the Dialysis schedule that it almost becomes a lifestyle of his. Patients have to follow up medical appointments regularly, do dialysis diligently and maintain a good diet.
  • Your vascular system is made up of blood vessels that carry your blood throughout your body. Arteries carry oxygen-rich blood away from your heart. Veins carry oxygen-poor blood back to your heart. Your blood leaves the left side of the heart and is pumped out to the rest of your body.
  • The main artery from your heart is called the aorta. As your blood travels around your body, it enters smaller and smaller blood vessels, reaching every cell, dropping off nutrients and picking up waste products and carbon dioxide.
  • Your blood then starts the trip back in your veins, entering larger and larger ones as it goes, passing through your kidneys and liver on the way to drop off waste products. The blood eventually arrives back at the right side of your heart to start the trip all over again.
  • As we age, our arteries tend to thicken, get stiffer and then narrow. This is called arteriosclerosis. A form of arteriosclerosis is atherosclerosis, which is the build-up of plaque and cholesterol in large and medium-sized arteries. Narrowing of the arteries from the build-up of plaque can lead to coronary heart disease, and can cause a heart attack when this occurs in the blood vessels leading to the heart.
  • The same situation in the arteries leading to the brain can cause strokes. Narrowing of the arteries in other places, such as your legs, can cause what is called Peripheral Arterial Disease, or PAD. PAD can lead to sores, pain with walking or, in the worst case, amputation. When the smaller arteries are affected, it is called arteriosclerosis.
An Artery is a blood vessel which is carrying oxygenated blood away from the heart to other organs in the body. It has walls that are quite thicker than veins because it carries high-pressure, oxygenated blood to different parts of the body. Coronary artery disease (CAD) is one type of arterial disease that affects blood flow through coronaries (arteries in the heart). It is also called coronary heart disease or simply coronary. Doctors for the treatment of an artery in Singapore can help. Arteries are the blood vessels that carry oxygen-rich blood with nutrients from the heart to the body’s cells. They are elastic and flexible tubes, with muscle walls that expand and contract according to the needs of the body. Arteries have three layers: an inner lining made of epithelial cells, a middle layer of smooth muscles cells, and an outer layer formed by connective tissue fibers. The wall of arteries is thicker than any other kind of blood vessel in order to maintain their structural integrity when carrying high-pressure blood flow at all times Arteries are responsible for nourishing tissues with freshly oxygenated blood so that it can be used for energy. Atherosclerosis is the main cause of coronary artery disease which restricts blood flow through arteries to heart muscles and can trigger a Heart Attack anytime. It occurs when fat (lipids) like Cholesterol deposits in Arterial walls and hardens over time thus restricting blood flow resulting in less oxygen supply to the heart muscles leading to chest pain called angina or even a full-blown massive Heart Attack known as Myocardial infarction (MI). The earlier you catch the symptoms and visit a doctor for an artery in Singapore, the better are your chances of survival. Dissection or aneurysm is the condition in which the Artery walls suddenly tear apart resulting in blood leakage either into the arterial walls or outside it. This can be fatal because of massive bleeding inside the body. The major cause is Prolonged high blood pressure, smoking, and tanned skin. Thrombosis is a common type of heart disease where small clots are formed on the inner linings of the artery restricting blood flow thus causing chest pain is known as angina pectoris also called “Sudden Cardiac Arrest”. It happens when one of these plaques becomes weak or ulcerates with time and ruptures spilling fat in Arterial walls that trigger clotting leading to occlusion (blockage) in the artery which decreases the oxygen supply to the heart muscles and restricts blood flow to vital organs causing sudden death. The major cause is smoking, high blood pressure, and diabetes that why you need to visit doctors for an artery in Singapore. Embolism is the sudden blockage of an artery in any part of the body due to a clot or a foreign object which gets stuck in Artery walls. It usually occurs in legs where fat from blocked ankles enters into veins and blocks vessels that carry oxygenated blood thus causing pain, swelling or even serious medical emergencies like Pulmonary embolism (PE) when it reaches lungs leading to shortness of breath, chest pain, and cardiovascular collapse if not treated on time by surgery or medication as according to symptoms. It happens when small clots form at the site of the arterial plaque rupture spilling inside artery walls forming clots inside the artery which dislodges and travels to other parts of the body causing a blockage in blood vessels. Thromboembolism is a condition where a clot or piece of the clot breaks off from an Artery that gets stuck in another part of the body blocking the flow of oxygenated blood resulting in chest pain, shortness of breath, and even heart attack if not treated on time. It happens when either part of arterial plaque ruptures forming clots inside the artery walls that dislodge due to exertion during physical activity like walking, climbing stairs also known as Physical stress thus traveling through veins to reach the lungs leading to Pulmonary embolism (PE). People suffering from any form of Coronary disease are recommended healthy changes in diet like daily intake of dark green leafy vegetables rich in Folic acid (Vitamin-B9) that helps in lowering blood homocysteine levels. It is advised to avoid drinking alcohol on regular basis, quit smoking, maintain a healthy body weight close to the BMI chart with regular physical exercise and stay away from stress since all these contribute to worse Coronary artery disease. Visit your doctors for the treatment of an artery in Singapore regularly.
  • Vascular conditions affect the veins and arteries in your body, which conduct oxygen to every living cell. Think of your veins and arteries as expressways or rivers. When there are traffic jams or road construction, or when dams break, trouble ensues. But in most cases, vascular conditions are highly treatable, often without surgery.
  • It is important to see a vascular surgeon, even when surgery is not needed. Vascular surgeons specialize in treatments of every kind of vascular problem except those of the heart (which are treated by cardiovascular/cardiothoracic surgeons) and the brain (which are treated by neurosurgeons). A common condition such as atherosclerosis may show up in the legs, for example, but affects the whole body.
  • Vascular surgeons will talk to you about how exercise, diet and medication can be the first step in regaining your health. When surgery is needed, vascular surgeons are trained in all types of interventions, not just one or two.

"I went for a colonoscopy, gastroscopy, and hemorrhoidectomy procedure with Dr Melvin Look. It was nerve wrecking for me to go under general anesthesia (GA) but Dr Look eased my fears with his calm and confident demeanour along with his funny disposition. Had a smooth and successful procedure with attentive pre- and post-op care from Dr Look who has been very patient with all my questions before and after the surgery!"

Melody Chong, 45 Patient

I met Dr Sam Peh in 2018 when I was admitted to parkway east hospital for acute unrinary retention . Subsequently in the same year I had TURP procedure .Some tissues from TURP was found to be cancerous . We just monitor the situation on 6 monthly psa reading In 2020 the psa reading spiked and am MRI scan shows 2 lesions in the prostate Dr. Peh give me the option to burn the 2 lesions using the HIFU technology. I’m glad to use HIFU as the downtime was like only a day. Dr Peh always explain the procedures to me using simple layman’s language and with drawings as illustrations. I feel safe and confident with Dr Peh as my urologist.

Philip Whang Patient
