Vascular rings are a congenital abnormality of the aorta that can put pressure on the windpipe and esophagus, causing symptoms such as difficulty breathing and swallowing. Surgery is the recommended treatment, and it is a relatively low-risk procedure. Vascular rings are usually diagnosed when people are very young. A vascular ring is a congenital abnormality […]
Peripheral vascular disease (PVD) affects arteries in the arms and legs, causing pain, weakness, and slow healing sores. It is caused by a buildup of plaque and is more common in men over 50, African Americans, and those with a family history of heart disease. Treatment includes quitting smoking, exercise, a balanced diet, medication, and […]
Improving vascular function is important for overall health. Quitting smoking, exercising daily, managing weight, monitoring blood pressure, taking folic acid supplements, avoiding crossing legs, taking breaks during activities, and consuming chocolate and Coenzyme Q10 in moderation can all help improve vascular function. Vascular function is vital for optimal health, and there are a number of […]
Ischemic vascular disease is caused by narrowing of blood vessels due to atherosclerosis, which can lead to peripheral artery disease, heart attacks, strokes, and dementia. Prevention includes exercise, healthy weight, diet management, and quitting smoking. Ischemic vascular disease is a condition characterized by narrowing of blood vessels. When arteries are severely constricted and blood flow […]
Vascular technologists use non-invasive ultrasound and Doppler technology to assess the circulatory system. They require an associate’s degree and certification, and job growth is predicted to be 20% over the next decade. A vascular technologist is a clinical healthcare professional who performs non-invasive assessments on the arteries and veins of a patient’s peripheral circulatory system. […]
Vascular sonographers use ultrasound to diagnose vein and artery problems, requiring a two-year academic program and credentials from CCI or ARDMS. Accredited schools teach general sonography and blood flow identification, with advancement opportunities available in administration or education. A vascular sonographer is a vascular technologist who uses ultrasound as a diagnostic tool to assist physicians […]
Vascular Doppler ultrasound is a non-invasive medical test that uses high-frequency sound waves to detect blood flow and abnormalities in major veins and arteries. It is safe and does not use ionizing radiation. Anyone who has looked at the local weather forecast or looked at an echo sounder has seen a Doppler image. The medical […]
Vascular resistance is affected by the diameter, length, and viscosity of blood vessels. Vasoconstriction increases resistance, and there are two types: systemic and pulmonary. High blood pressure is caused by increased vascular resistance or cardiac output and can lead to serious conditions. Medications and lifestyle changes can help manage hypertension. Vascular resistance describes the degree […]
Plants rely on their vascular system to transport water and nutrients, with xylem transporting water and phloem moving organic nutrients. The system is found in vascular bundles and includes a layer called the vascular cambium, which segregates xylem and phloem and is responsible for stem cell differentiation. The plant vascular system, filled with tube-like vascular […]
Vascular dysfunction is a disorder where blood vessel function is disrupted, causing reduced blood flow and impaired circulation. Women are particularly prone to this condition, which can lead to delays in diagnosis of conditions such as myocardial ischemia. Diagnostic tools include heart function tests and measuring blood pressure and flow. Patients with a family history […]
Collagen vascular disease is caused by a malfunctioning immune system that affects the skin, joints, and tendons, resulting in conditions such as rheumatoid arthritis, scleroderma, and dermatomyositis. Treatment involves anti-inflammatory medication and physical therapy. Boosting the immune system through exercise and diet can provide relief. Collagen is a fibrous protein that acts as a glue […]
Vascular inflammation, or atherosclerosis, is caused by the buildup of plaque in arteries and can lead to narrowed passages, blood clots, and organ damage. Lifestyle changes and medication can manage the condition, but severe cases may require surgery. Symptoms vary and can include numbness, weakness, and pain. Vascular inflammation is a potentially serious medical condition […]
Vascular ulcers are open sores on the foot or toes caused by poor circulation, often due to vascular disease or diabetes. Treatment can include dressings, medication, or surgery. Compression wraps, blood thinners, and antibiotics may also be used. Severe cases may require surgery to restore blood flow. A vascular ulcer is a typically painful open […]
A vascular technician helps care for patients with heart and circulatory system disorders by conducting screenings, operating testing equipment, and reviewing test results. They must have specialized knowledge of complex test equipment and often work alongside experienced professionals. Certification is not always required, but many choose to take exams to improve their credentials. There is […]
Vascular malformations are abnormalities in blood vessel formation, with several types including arteriovenous malformations, capillary malformations, lymphatic malformations, venous malformations, and combined vascular malformations. Arteriovenous malformations are particularly dangerous, as they can cause fatal strokes. Treatment options include surgery, embolization, and radiosurgery. Other types of vascular malformations can also have visible symptoms and require different […]
Vascular permeability is regulated by the endothelium and determines which molecules can pass through blood vessels. VEGF is the major determinant and is linked to cancer, but inhibiting it could prevent the spread of malignant tumors. Animal studies have shown some control of permeability in colon, brain, and breast cancer. Vascular permeability studies have also […]
Vascular disease affects blood vessels carrying blood to extremities, causing symptoms such as pain, skin discoloration, swelling, numbness, and varicose veins. It is often asymptomatic in early stages but can lead to gangrene if left untreated. It can also cause chest pain, arm pain, and tissue damage. The symptoms of vascular disease most commonly affect […]
