Intra procedure rupture of intracranial aneurysm during endovascular coiling: Neurosurgeons' experience and review of the literature

Objective: The aim of this study was to determine the incidence, risk factors and outcome of intra procedure rupture (IPR) during endovascular coiling of intracranial aneurysms, a neurosurgeons' experience.
Materials and Methods: The frequency of IPR was studied in 168 aneurysms treated by endovascular coiling in 150 consecutive patients. Aneurysm size, morphology, history of previous subarachnoid hemorrhage (ruptured) and timing of treatment after subarachnoid hemorrhage were the data collected for comparison.
Results: Procedure-related rupture during endovascular coiling occurred in five (2.97%) of the 168 aneurysms treated. IPR was the cause for 1.78% treatment-related deaths. Small aneurysm size was the major risk factor for IPR in this series (P < 0.001).
Conclusions: In this study, the frequency of IPR was similar to the reported frequency in the procedures performed by neurointerventionists.
