Introduction: Surgical outcome and ischemic complications of Internal carotid Posterior Communicating (IC PC) and anterior choroidal aneurysms have been questionable due to frequent occlusion of the anterior choroid artery and also due to low incidence of true anterior choroid artery aneurysms. The present series describes the postoperative outcome after clipping of such aneurysms at a single centre. Methods: A retrospective analysis of 73 cases with IC PC and Anterior choroidal aneurysms performed at a Fujita Health University, Banbuntane Hotokukai Hospital, Nagoya, Aichi, Japan from 2014 to 2018 have been studied and emphasis is made on the demography and ischemic complications. Results: A total of 73 patients with IC PC and anterior choroidal aneurysms were studied, out of which 57 patient had a true IC PC aneurysm, 14 patients had aneurysms involving the anterior choroidal artery and only 2 patients had aneurysms which involved both the IC PC and the anterior choroidal arteries. None of the patients had a permanent Anterior Choroidal Artery syndrome, whereas only 2 out of the 73 patients had postoperative complications in the form of transient hemiparesis. Conclusion: Ischemic complications following surgical clipping of IC PC and anterior choroidal aneurysms can be minimised by meticulous micro dissection to identify the anterior choroidal artery thus preserving the patency of the same.
