Vascular occlusion

Vascular occlusion is a violation of the patency of hollow structures (subarachnoid spaces, cisterns, lymphatic and blood vessels) in the body. This pathology occurs due to the closure of the lumen of these structures in some section.

Acute arterial occlusion is an acute blood flow disorder that occurs distal to the site of arterial blockage by a thrombus or embolus. This condition is considered urgent, since after 4-6 hours from its onset, necrotic irreversible changes develop in the body. Such pathology can develop as a result of rupture of an atherosclerotic plaque and subsequent thrombosis, embolism. Symptoms are characterized by sudden onset. The main ones are: severe pain, no pulse, paresthesia (anesthesia), a feeling of coldness in the extremities, paleness of the extremities. The vascular occlusion is localized approximately in the area of ​​the arterial bifurcation, distal to the place where the pulse can still be felt (for example, in the area of ​​the femoral artery bifurcation in the presence of a femoral pulse). In severe cases, motor function can be completely lost. And after 6-8 hours, the muscles become soft upon palpation.
