Vascular disease

As a circulatory disorder (English vascular disorder) is the restricted blood flow in a designated part of the vascular system, which leads to hypoperfusion of the supplied organs or tissues and thus to ischemia. Whether and to what extent the corresponding organs or tissue damage depends on the ischemic tolerance and the severity of circulatory disturbance. Both a reduced blood supply as well as an impaired outflow of venous blood or lymph can cause a circulatory disorder in an individual case alone or in combination. In restricted blood circulation in the capillary is called a microcirculation disorder are larger vessels cause of a fault in the macro circulation. Both forms can occur in combination.

Causes

Again, the underlying causes of many: In the arterial branch are atherosclerosis (vascular " calcification ") or a vascular occlusion ( by spasm, embolism, pressure on the vessels, etc. ), in venous leg thrombosis or chronic venous insufficiency ( with microcirculation disorder), (for example, to be mentioned in the lymphatic system, the soldering according to any one of the lymphatic vessels inadequately treated erysipelas, surgery, radiation therapy) followed by increasing the tissue pressure as an example.

Effects

Significant results are:

• Circulatory disorders of the heart muscle Prinzmetal's angina (with a spastic narrowed coronary artery ); Angina pectoris and heart attacks ( in CAD)
• In cerebral circulatory disorder, which is classified clinically according to the duration and reversibility of the disorder, although the classical differentiation of transient ischemic attack (TIA ), ( prolongiertem ) reversible ischemic neurological deficit ( RIND / PRIND ) and consummate ischemic stroke is now considered obsolete, see stroke
• In the intestinal circulation problems: abdominal angina, Mesenteric, Dunbar syndrome
• Infarction at a circulatory disorder of the kidneys or kidney problems ( part )
• Circulatory disorders of the lower extremities (usually multifactorial ) the leg ulcer
• With pressure damage a pressure sore (especially in bedridden people), a compartment syndrome, a park bench paralysis ( neurapraxia )

A special form of circulatory disturbance are the so-called Anzapfphänomene.
