noun, plural: embolectomies
When the blood clot is removed at its original site it is called thrombectomy. But when the clot came from a distant vessel and lodged to another vessel, the clot is called embolus and its surgical removal of it is referred to as embolectomy.
Embolectomy is an emergency surgical procedure. It is done on patients with vein insufficiency caused by an embolus clogging a blood vessel. This procedure is carried out as a last resort in order to remove the embolus associated with increased risk of heart attack and stroke.
