When the disease develops, a variety of signs can be observed in different body parts. For instance, patients may have pale skin, cold hands and feet, and numb fingertips. These are mainly due to the reduction in blood flow to the limbs, resulting in a decrease in heat distribution to these areas.
There is a recurrent acute and chronic inflammation and thrombosis of arteries and veins of the hands and feet. The main symptom is pain in the affected areas, at rest and while walking (claudication). [1] The impaired circulation increases sensitivity to cold. Peripheral pulses are diminished or absent. There are color changes in the extremities.
DVT usually occurs in the veins of the legs, although it can also occur in the veins of the arms. Immobility, active cancer, obesity, traumatic damage and congenital disorders that make clots more likely are all risk factors for deep vein thrombosis. It can cause the affected limb to swell, and cause pain and an overlying skin rash.
The peripheral vascular system is the part of the circulatory system that consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). [1] [2] The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back to ...
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Smokers are 2–3 times more likely to have lower extremity PAD than coronary artery disease. [39] Greater than 80%–90% of patients with lower extremity peripheral arterial disease are current or former smokers. [40] The risk of PAD increases with the number of cigarettes smoked per day and the number of years smoked. [41] [42]
Lesions are often greater than 5 cm in diameter and can cause visible deformity and pain. During early childhood, KHE may enlarge and after 2 years of age, it may partially regress. Though, it usually persists longterm. In addition, 50% of patients have coagulopathy due to thrombocytopenia (<25,000/mm3), presenting with petechiae and
Many patients with normal tension glaucoma have a basic constitution, which corresponds to the Flammer syndrome. Some of its features were formerly summarized under the term "primary vascular dysregulation syndrome". [5] Signs of Flammer syndrome include: cold hands or feet, or both; arterial hypotension; lower body mass index; decreased ...
