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.
