A thrombectomy is the process of removing a blood clot from the body using imaging guidance. The most common embolism is the arterial embolism that restricts the blood supply that leads to the affected area of the body.
A thrombectomy is performed by inserting a sheath using imaging guidance to remove the blood clot. This can be performed through catheter aspiration, where the blood clot is suctioned out, or through mechanical thrombectomy where the clot is broken up into smaller pieces for easier removal.
Additional test may be needed to diagnose what caused the thrombus in the first place. The thrombectomy may be used in tandem with a thrombolysis, which is a medication that helps to break down the blood clot.
