Stroke: Ischemic Stroke – Endovascular Thrombectomy
An ischemic stroke is caused by a blood clot that is blocking blood flow to sections of the brain thereby preventing areas of the brain from receiving necessary nutrients required for their survival. A minimally invasive cerebral angiogram is performed to assess the degree and location of blockage of arteries that supply the head and neck. This type of minimally invasive treatment begins with a small catheter containing specialized tools/devices being inserted in a blood vessel in the groin (femoral artery) and traveling inside the arteries to reach the neck and brain. Clot retrieval devices, stents, chemicals, and balloons may then be used to remove the blockage and restore blood flow to the affected areas of the brain.
