Three distal anterior cerebral artery aneurysms in the same branch associated with five additional intracranial aneurysms.

ABSTRACT: BACKGROUND:Multiple distal anterior cerebral artery (DACA) aneurysms appear as rare findings. Simultaneous treatment of such lesions can be particularly challenging. A report of three aneurysms on the same parent artery has not been reported before. We report a case of three DACA aneurysms treated within one microsurgical operation in a patient with eight aneurysms. CASE DESCRIPTION:A 62-year-old woman incidentally presented with multiple various size saccular aneurysms, including tree on the left DACA. One of the DACA aneurysm was located on the A3 segment, and the other two were on the A4 and A5 segments. Ligation of all three of these aneurysms was planned in one operation. A standard anterior interhemispheric approach was utilized. Three aneurysms were successfully clipped using four clips. Intraoperative angiography confirmed aneurysm occlusion with parent artery patency preservation. The patient showed no new postoperative neurological deficit. CONCLUSION:Clipping multiple DACA aneurysms within a single microneurosurgical operation is a feasible treatment option. Meticulous analysis of preoperative imaging features is crucial for selecting the best, patient-specific treatment strategy.

Project description:BackgroundThe occurrence rate of distal anterior cerebral artery (DACA) aneurysms is relatively low, primarily due to their deep-seated location, which makes surgical clamping challenging. The objective of this study was to investigate the efficacy and safety of computed tomography (CT) navigation-assisted clipping of DACA aneurysms compared to traditional clipping without navigation.MethodsA retrospective cohort study involving retrospective data collection was performed. The retrospective analysis was conducted on 139 patients with ruptured DACA aneurysms who underwent clipping. From January 2013 to November 2021, 164 patients were retrieved at the Department of Neurosurgery, Renmin Hospital of Wuhan University. The inclusion criteria were patients diagnosed with DACA aneurysms via CT angiography (CTA) or digital subtraction angiography (DSA), those with complete clinical data, and those who underwent craniotomy for aneurysm clipping. Meanwhile, the exclusion criteria were as follows: aneurysm recurrence, traumatic brain injury or surgery history, blood disorders or recent anticoagulant use, and severe organ dysfunction. Data on gender, age, Hunt-Hess grade, Fisher grade, modified Rankin Scale (mRS) score, aneurysm location, hospitalization time, aneurysm found time (the duration from incision to aneurysm discovery), and intraoperative bleeding volume were collected from medical records and neurosurgical databases. Patients were followed up in the clinic or by telephone in May 2022. All patients were divided into a navigation group or a traditional group for statistical analysis.ResultsNo statistically significant differences were observed in age, sex, Fisher grade, Hunt-Hess grade, hospitalization time, or aneurysm site between the navigation group and traditional group (P>0.05). Intraoperative blood loss was lower in the navigation group than in the traditional group {370 [280-460] vs. 430 [310-610] mL, P=0.045}. Patients in the traditional group had a shorter aneurysm found time than did those in the navigation group {49 [42-53] vs. 79 [63-84] min, P<0.001}. There was no significant difference in the mRS score at hospital discharge (P=0.336) or follow-up (P=0.157) between the two groups.ConclusionsCT neuronavigation-assisted microsurgery for clipping DACA aneurysms may improve surgical accuracy, shorten the time to locate aneurysms, and reduce intraoperative blood loss. Although no significant difference in prognosis was observed, this technique shows promise as a safe and effective alternative to traditional clipping without navigation.
