Virchow's Triangle The three pathalogical factors assc'd w/thrombosis: venous stasis,increased blood coagulability,and vessel wall injury.
6 P's Pain,pulse,pallor,paresthesia,paralysis,poikiolthermia
Arteriosclerosis Thickening,loss of elasticity, and calcification of the arterial walls.
Atherosclerosis Lining of medium and large arteries are affected by lesions (atheromas or plaque) that may block blood flow.
Embolism Sudden obstruction of a blood vessel by debris.
