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%. [29] Another intervention for acute cerebral ischemia is removal of the offending thrombus directly.
When someone has a stroke, a blood vessel to the brain bursts or is blocked by a clot. The result: Part of the brain cannot get the oxygen and nutrients it needs from blood, so brain cells die ...
Carotid endarterectomy: A carotid endarterectomy is a minimally invasive procedure to remove plaque from within your carotid artery, the main blood vessel that carries blood to your brain.
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.
