Acute embolic occlusion of a limb artery is a rare but serious medical emergency because acute limb ischemia is limb-threatening. The early recognition and operative treatment of embolic arterial occlusion of the extremities is still relatively infrequent. When a clot or embolus blocks a major or deep vein, blood pools behind the obstruction, causing inflammation. Reperfusion takes several hours, and in about 25% of acute vascular occlusions lysis is not achieved, especially if there is embolic occlusion. Embolic occlusion of patent foramen ovale is an important cause of false negative microbubble contrast study. Embolic occlusions predominated. Old age, atrial fibrillation, severe abdominal pain and synchronous embolus suggest the diagnosis of acute bowel ischaemia.About half of the patients (47.4%) had embolic occlusions. Embolic occlusion of superior mesenteric artery (SMA) is a potentially fatal condition with a high mortality rate. Arterial embolism can cause occlusion in any part of the body. It is a major cause of tissue death from blockage of the blood supply. Embolus lodging in the brain from either the heart or a carotid artery will most likely be the cause of a stroke due to ischemia. The early recognition and operative treatment of embolic arterial occlusion of the extremities is still relatively infrequent.
