The influence of temporary occlusion of parent vessel on outcome of surgical treatment of ruptured cerebral aneurysms

Abstract

Background/Aim. Aneurysm rupture followed by sub-arachnoid or intracerebral haemorrhage is always current topic and poses a great challenge to neurosurgeons. The aim of the study was to establish whether applying temporary occlusion before placing a final clip was justified. Methods. A prospective study was conducted on patients with aneurysm rupture, treated at Neurosurgical Clinic in Nis from January 2012 to December 2016. Patients belonging to I and II and 1, 2 and 3 grades according to the Hunt-Hess grading system and Fisher scale, respectively, were monitored. Results. In 85, out of total 182 bleeding aneurysms that were treated, a neurosurgeon decided to apply temporary clipping before placing the final clip. Temporary occlusion significantly influenced the presence of resulting neuro-logical deficit. Conclusion. The application of temporary occlusion facilitates placing the final clip but also affects the occurrence of neurological deficits. It is assumed that this is a consequence of caused vasospasm, considering that these are bleeding aneurysms.
