Abstract Distal anterior choroidal artery aneurysms with intraventricular hemorrhage are rare and difficult to treat. We report the case of a 46-year-old woman with a left distal anterior choroidal artery aneurysm presenting as a typical subaraehnoid hemorrhage from which she had no focal neurological signs. Because the aneurysm was located within the dominant deep temporal lobe, we used intraoperative computed tomography to guide a probe to the aneurysm to allow minimal dissection. This is the first report of a successfully treated distal anterior choroidal artery aneurysm. Reports of this unusual aneurysm and methods of approaching deep temporal lesions are reviewed.

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.

Abstract Surgical treatment of anterior choroidal artery (AChA) aneurysms is challenging because of the constrained operative corridor and limitations imparted by the surrounding rigid structures during the exposure. The AChA most commonly arises as a single branch from the communicating (C7) segment of the internal carotid artery but has 2 to 4 branches in approximately one-third of cases, and aneurysms generally arise from the parent vessel interface with these branches. This patient experienced a sentinel headache 4 d before presenting with subarachnoid hemorrhage. The patient had a large right AChA aneurysm with a unique configuration in which the parent vessel was located anterior to the aneurysm. Endovascular therapy was aborted because there was an AChA branch at the base of the aneurysm. An orbitozygomatic craniotomy was performed that provided transsylvian access to the region of interest. Clip application was challenging because of the close proximity of the branch vessels. Intraoperative indocyanine green evaluation and postoperative angiogram showed patency of the AChA and posterior communicating artery. This video demonstrates the surgical challenge associated with AChA aneurysms because of the proximity of adjacent structures and highlights the importance of meticulous technique during clip application. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary.
