Peripheral veinous disease, on the other hand, refers to problems with veins—the vessels that bring the blood back to the heart. [ 18 ] The classic symptom is leg pain when walking, which resolves with rest and is known as intermittent claudication . [ 2 ]
Three main changes are seen in the mechanism of Raynaud's phenomenon which are reduced blood flow, blood vessel constriction, and neurogenic, inflammatory, and immune responses. It is induced by mental stress and a cold atmosphere. In all cases, the primary cause is an underlying hyperactivation of the sympathetic nervous system. [19]
Central cyanosis is often due to a circulatory or ventilatory problem that leads to poor blood oxygenation in the lungs. It develops when arterial oxygen saturation drops below 85% or 75%. [5] Acute cyanosis can be a result of asphyxiation or choking and is one of the definite signs that ventilation is being blocked.
Dr. Denniston notes that signs of poor blood circulation can include leg pain after walking, cold hands and feet, white fingertips, varicose veins, slow wound healing, numbness, tingling, blue ...
Symptoms of acute compartment syndrome (ACS) include severe pain, decreased blood flow, decreased movement, numbness, and a pale limb. [5] It is most often due to physical trauma, like a bone fracture (up to 75% of cases) or a crush injury. [3] [6] It can also occur after blood flow returns following a period of poor circulation. [4]
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.
Erythromelalgia - a rare peripheral vascular disease with symptoms that include burning pain, increased temperature, erythema and swelling that generally affect the hands and feet. [17] Renal artery stenosis - the narrowing of renal arteries that carry blood to the kidneys from the aorta. [2]
Smaller arteries carry blood supply from the popliteal artery to the calf and into the foot. [4] Blockages caused by plaque build-up or atherosclerosis in any of these arteries can reduce leg blood circulation, causing leg pain that may interfere with daily life. [4] Standard popliteal bypass surgery involves the bypass of the popliteal artery. [5]
