Risk Factors for the Recurrence of Posterior Communicating Artery Aneurysm: The Significance of Fetal-Type Posterior Cerebral artery

Posterior communicating artery (PcomA) is the second most common location for the formation of intracranial aneurysms (IAs), accounting for about 15 –25% of all IAs and 50% of all internal carotid artery (ICA) aneurysms.1,2 Recent study suggested that PcomA aneurysms are more likely to rupture compared to aneurysms located at other sites, even in a small sized aneurysms.1 Microsurgical clipping and endovascular treatment (EVT) have been the tw o main treatment methods for IAs. Although the clinical and radiologic outcome of clipping or coiling has been much improved, the recurrence rate of clipping and coiling is 2.9% and 15–33%, respectively.
