Abstract
A method of performing an operation including angioplasty of the internal carotid artery which includes blocking blood flow in the internal carotid artery, performing the angioplasty while the blood flow is blocked in the internal carotid artery, and reversing flow in the internal carotid artery after the angioplasty has been performed to wash material loosened during the angioplasty out of the internal carotid artery. Normal flow in the internal carotid artery is restored after the loosened material is washed out of the internal carotid artery.
