Drs. Patel and Moyle perform a cerebral angiogram.

Interventional endovascular physicians perform diagnostic and therapeutic angiographic procedures. An angiogram involves the placement of a catheter into the artery in the thigh with the injection of contrast into the arteries that enter the brain. Through minimally invasive techniques, these physicians can treat a variety of vascular problems such as injecting clot-busting medication into brain clots to treat stroke, coiling off aneurysms (abnormal ballooning of blood vessels that is prone to rupture) to treat subarachnoid hemorrhage or stenting of stenotic (tightened) carotid arteries, among others.
