It is commonly performed in the cerebral arteries (interventional neuroradiology) as treatment to reverse the ischemia in some ischemic strokes (i.e., those in which the blockage is a suitable candidate for such retrieval). Open vascular surgery versions of thrombectomy also exist. The effectiveness of thrombectomy for strokes was confirmed in ...
It usually involves removal of thrombi (blood clots), and is then referred to as thromboembolectomy or thrombectomy. Embolectomy is an emergency procedure often as the last resort because permanent occlusion of a significant blood flow to an organ leads to necrosis .
In increasing numbers of primary stroke centers, pharmacologic thrombolysis with the drug tissue plasminogen activator (tPA), is used to dissolve the clot and unblock the artery. Giving rTPA lessens the chance of disability after 3 months by 30%. [30] Another intervention for acute cerebral ischemia is removal of the offending thrombus directly.

MERCI Retriever L5. The MERCI Retriever is a medical device designed to treat Ischemic Strokes.The name is an acronym for Mechanical Embolus Removal in Cerebral Ischemia. . Designed by University of California, Los Angeles in 2001, MERCI was the first device approved in the U.S. to remove blood clots in patients who had acute brain isch
Mechanical removal of the blood clot causing the ischemic stroke, called mechanical thrombectomy, is a potential treatment for occlusion of a large artery, such as the middle cerebral artery. In 2015, one review demonstrated the safety and efficacy of this procedure if performed within 12 hours of the onset of symptoms.
Over 90% of stroke-causing clots that originate in the heart in patients with non-valvular AF are formed in the left atrial appendage. [ 2 ] [ 3 ] LAAO does not completely eliminate the risk of stroke in patients with AF but it does reduce the risk of stroke from emboli that originate in the left atrial appendage. [ 4 ]
However, when arising outside this context, blood clots can wreak havoc in the human body, including disabling strokes. Thrombolysis is the process of breaking down blood clots, by injecting them with powerful medications. Thrombectomy involves using a device to remove the clot directly.
