Abstract
Purpose To explore factors affecting the prognosis of choroidal anterior artery aneurysm
(AChAA) and provide a reference for improving the postoperative outcome.
Methods The clinical data of 86 patients with AChAA who underwent treatment by a single surgeon
were collected and analyzed retrospectively. Univariate analysis and multivariate
logistic regression analysis were conducted to examine 12 factors that possibly affected
outcome.
Results The five factors that affected the patient outcomes were times of subarachnoid hemorrhage
(SAH), characteristics of SAH on computed tomography (CT), Hunt-Hess grade, aneurysm
size, and presence or absence of postoperative complications. Characteristics of SAH
on CT (odds ratio [OR]: 3.727; p = 0.000; 95% confidence interval [CI], 1.850–7.508), aneurysm size (OR: 6.335; p = 0.000; 95% CI, 2.564–15.647), and presence or absence of postoperative complications
(OR: 4.141; p = 0.000; 95% CI, 1.995–8.599) were independent risk factors influencing the prognosis.
In addition, the incidence of postoperative ischemia (caused by anterior choroidal
artery syndrome) is related to the aneurysm emitting part and presence or absence
of intraoperative rupture.
Conclusions The analysis of characteristics of SAH on CT, aneurysm size, and presence or absence
of postoperative complications can roughly determine the outcome of patients with
AChAAs.
