1. Head and Neck
A narrowing or blockage in the carotid arteries, which supply blood to the brain, increases the risk of stroke. Over time, plaque buildup can lead to a transient ischemic attack (TIA) or a more severe stroke. Learn More

A brain attack occurring when blood flow is blocked or a vessel ruptures. Without rapid intervention, it can cause permanent paralysis, speech difficulties, and long-term neurological impairment. Learn More

Transient ischemic attacks or "mini-strokes" that temporarily interrupt brain blood flow. Cause brief neurological symptoms and serve as critical warning signs of potential future stroke risk. Learn More

A condition affecting blood vessels supplying the brain's posterior circulation. Can cause dizziness, vision problems, and increased risk of stroke through vessel narrowing or blockage. Learn More

2. Chest and Abdomen
A weakened section in the upper aorta that can grow silently until rupture. If left untreated, it poses a critical risk of sudden, life-threatening internal bleeding. Learn More

An aortic aneurysm happens when the abdominal aorta weakens and expands, forming a bulge that can rupture if not treated. AAA often develops silently, with little to no symptoms, until it becomes a serious threat. Learn More

A complication after endovascular aneurysm repair (EVAR), an endoleak occurs when blood continues to flow into the aneurysm sac, increasing the risk of rupture. There are five types, each requiring specific management. Learn More

Reduced blood flow to the intestines can cause severe abdominal pain, particularly after eating. Chronic cases may result in malnutrition, while acute cases can be life-threatening. Learn More

A rare but serious aneurysm in arteries supplying major organs. The primary risk is sudden rupture and potentially fatal internal bleeding. Learn More

Plaque buildup can narrow or block the aorta and iliac arteries, reducing blood flow to the legs. Also known as aortoiliac disease, it can cause leg pain, cramping, and difficulty walking. Learn More

A tear in the inner layer of the aorta allows blood to flow between layers of the artery wall, potentially leading to life-threatening complications. If it occurs in the upper part of the aorta, it’s called an ascending aortic dissection; if in the lower part, it’s a descending aortic dissection. Learn More

Narrowing of arteries supplying the kidneys and intestines can trigger progressive high blood pressure and kidney dysfunction. Left unchecked, it risks permanent organ damage. Learn More

Abnormal blood vessel bulges combined with progressive arterial narrowing that can lead to reduced blood flow and potential rupture. Pose significant risks of stroke and critical organ damage. Learn More

3. Upper Extremity

Poor circulation in the arms, also called arm arterial disease or upper extremity arterial disease, can lead to pain, weakness, or cold hands. It may be associated with steal syndrome or peripheral vascular disease. Learn More

Also known as an Ulnar Artery Aneurysm, this occupational condition is caused by repeated hand trauma, damaging the ulnar artery. Affects workers with repetitive hand impact activities, potentially leading to artery damage and compromised hand circulation. Learn More

Compression of nerves or blood vessels in the upper chest causing pain, numbness, and swelling in the arms. Prolonged condition can lead to permanent nerve and circulation damage. Learn More

4. Lower Extremity
Conditions affecting vein function, causing blood pooling, swelling, and potential clot formation. Can lead to varicose veins, leg pain, and increased risk of deep vein thrombosis.
  • Acute Deep Vein Thrombosis Dangerous blood clot formation in deep veins, typically in legs, that can potentially break loose and cause life-threatening complications like pulmonary embolism.
  • Pulmonary Embolism Critical condition where blood clots block lung arteries, causing sudden breathing difficulties and potentially fatal cardiovascular complications.
  • Chronic Venous Insufficiency When leg veins struggle to return blood to the heart, it can cause swelling, pain, and skin changes. This condition can lead to venous insufficiency, phlebitis, post-thrombotic syndrome, or venous leg ulcers.
  • Varicose Veins Twisted, enlarged veins in the legs that cause aching, swelling, and discomfort. Without management, they can progress to more serious circulatory complications.
Learn More

A buildup of fluid in the lymphatic system causes swelling, usually in the arms or legs. It can develop from genetic factors, surgery, or damage to lymph nodes, leading to discomfort and mobility issues Learn More

A buildup of fluid in the lymphatic system causes swelling, usually in the arms or legs. It can develop from genetic factors, surgery, or damage to lymph nodes, leading to discomfort and mobility issues Learn More

A bulge or weakening in an artery outside the aorta, most commonly found in the legs, especially the popliteal artery behind the knee. It can lead to blood clots, reduced circulation, and serious complications such as embolism, limb-threatening ischemia, or vessel rupture if left untreated. Learn More

Narrowed arteries reduce blood flow to the limbs, causing pain, cramping, and weakness. PAD significantly increases the risk of non-healing ulcers and potential limb amputation.
  • Claudication Leg pain caused by reduced blood flow during physical activity, typically resulting from peripheral artery disease. Patients experience muscle pain that subsides with rest.
  • Chronic Limb Threatening Ischemia Advanced stage of arterial disease with severe reduction in blood flow, causing constant pain and high risk of tissue loss. Requires immediate medical intervention to prevent amputation.
  • Diabetic Foot Serious complication of diabetes involving reduced circulation and nerve damage. Increases risk of infections, ulcers, and potential limb amputation due to poor wound healing.
  • Non-Healing Wounds Chronic wounds that fail to progress through normal healing stages, often caused by poor circulation, diabetes, or compromised immune systems. Can lead to serious infections and tissue damage.
  • Gangrene Severe tissue death caused by complete loss of blood supply, typically affecting extremities. Can result from advanced vascular disease, diabetes, or serious infections.
