The important role of superficial artery histological structure in extracranial intracranial arterial anastomosis

Abstract

Since extracranial intracranial artery anastomosis was pioneered by Yasargil in August 1967, this surgical method has undergone significant development recently. In order to ensure satisfactory compensation of the middle cerebral artery or internal carotid artery, the anastomosis must be performed between proportional vessels of approximately 1 mm in diameter. The operation achieved amazing clinical results, and post-operative angiography demonstrated significant dilation of the anastomotic vessels. This article introduces a 43-year-old patient with stenosis of the intracranial horizontal segment of the internal carotid artery. Two months after the operation, the cerebral angiography image showed that the middle cerebral artery through the anastomosis was well filled and the superficial temporal artery was significantly dilated.
