Mechanical thrombectomy - a new way to remove blood clots that block the cerebral blood vessels

12 March 2020

Mechanical thrombectomy is a new method for removing blood clots that block the cerebral blood vessels. Blood clots blocking the cerebral blood vessels lead to stroke, malfunctioning of the area covered by the blocked blood vessel, followed by cerebral infarction and death of the affected brain part. Cerebral infarction can occur within a short period of time if the blockage is not eliminated.

“Due to modern imaging techniques, a new, minimally invasive method has been developed to remove blood clots that block the cerebral blood vessels. Previously, only an intravenous medicine that helped the dissolution of the clot was used for this purpose but it rarely eliminated blockages in larger cerebral blood vessels,” says Professor András Büki, director of the University of Pécs Department of Neurosurgery.

During mechanical thrombectomy, special, very small, corkscrew-like devices can be inserted to the blood clot causing the blockage and removing it from the blood vessel with the help of X-ray imaging. The procedure begins with puncturing the femoral artery in the groin.

Through the femoral artery, a guide catheter with a diameter of 2 to 3 mm is inserted into one of the major carotid arteries, from where smaller diameter catheters are inserted into the guide catheter to access the blocked cerebral artery.
