Endovascular treatment of intracranial posterior communicating artery aneurysm with Guglielmi detachable coil

Objective To discuss the techniques and managements of complications in endovascular embolization on posterior communicating artery aneurysm (PComAA) with Guglielmi detachable coils (GDC), and to evaluate the effect of treatment. Methods A total of 42 cases with PComAA were treated with GDC to embolize the aneurismal sac via femoral artery approach. Early intervention of hemorrhage was performed post-operation. Results All 42 patients were cured, in which 41 cases recovered clinically, 1 patient died. The mortality was 2.4%. The sac of 38 aneurysms were achieved 100% embolization, 3 with 95% embolization, 1 with 90% embolization. Aneurysms had not repunctured during the embolization. 1 case happened cerebral vasospasm. 1 case microcoil escaped. One recurring cases cured by second GDC embolization. The technique-related complications were present in 2 cases. No re-bleeding occurred in the 3-50 months follow-up. Conclusion GDC occlusion is a safe and effective treatment for the PComAA. Advances in the techniques and treating the complications correctly will decrease the complications and improve future outcomes.
