Ischemic stroke of the anterior choroidal artery(
AChA)is the most common and serious complication after
AChA aneurysm treatment. The purpose of this study was to retrospectively evaluate and compare the treatment-related ischemic complications after surgical clipping and endovascular coiling of
AChA aneurysms.<br/> Between June 2006 and March 2013, 32 patients with 34
AChA aneurysms were treated in our hospital by surgical clipping or endovascular coiling. There were 12 cases of
ruptured aneurysms, seven cases of unruptured
aneurysms, and 15 cases of incidentally identified unruptured
aneurysms. Of the 34
aneurysms, 19 were managed with surgical clipping and 15 were managed with endovascular coiling. No rebleeding or
retreatment occurred in any case during 4-84 months(median, 25 months)of follow-up, and no significant differences in clinical outcome were seen between clipping and coiling cases. Although there were four cases(11.8%;surgical clipping in three;endovascular coiling in one)of postoperative
AChA infarction, we believe that we preserved the blood flow of the
AChA during the procedure. The occurrence of
subarachnoid hemorrhage and premature
rupture during surgical clipping were significantly correlated with
AChA infarction.
