End-to-Side Anastomoses in Small Arteries with Partial Lateral Clipping. An Experimental Study

Abstract

The problem of total therapeutic occlusion of the cranial arteries remains a relatively important area of concern for neurosurgery, neurology, neuroradiology and neuroanesthesia as well as for the patients. Cerebral revascularization procedures require total occlusion of the cranial arteries for a while. End-to-side anastomoses with partial lateral clipping were done in 20 cadaver arteries and then, in one rat common carotid artery. The results of the study were compared with the current cerebrovascular bypass procedures on a theoretical basis and possible clinical implications of the method were suggested. All the anastomoses were found to be open. As conclusions; 1) End-to-side anastomosis with partial lateral clipping and along with this technique the maintenance of blood flow in the target vessel during the anastomosis procedure are experimentally possible. 2) Although the available aneurysm clips may be used in the bigger vessels (> 2.5 mm), currently, the exclusive clips for the technique are not available commercially. 3) Further clinical implications of the technique may be investigated.
