Background and objective: Current data on the optimal treatment modality for ruptured anterior communicating artery (AComA) aneurysms are limited. We conducted this multicenter retrospective study to evaluate the safety and clinical outcomes of endovascular treatment (EVT) and microsurgical clipping (MC) for the treatment of ruptured AComA patients. Methods: Patients with ruptured AComA aneurysms were screened from the Chinese Multicenter Cerebral Aneurysm Database. Propensity score matching (PSM) was used to adjust for baseline characteristic imbalances between the EVT and MC groups. The safety outcomes included total procedural complications, procedure-related morbidity/death and remedial procedure for complication. The primary clinical outcome was 2-year functional independence measured by the modified Rankin scale (mRS) score. Results: The analysis included 893 patients with ruptured AComA aneurysms (EVT: 549; MC: 346). PSM yielded 275 pairs of patients in the EVT and MC cohorts for comparison. Decompressive craniectomy being more prevalent in the MC group (19.3% vs. 1.5%, p< 0.001). Safety data revealed a lower rate of total procedural complications (odds ratio [OR] = 0.62, 95% CI 0.39-0.99; p= 0.044) in the EVT group and similar rates of procedure-related morbidity/ death (OR = 0.91, 95% CI 0.48-1.73; p= 0.880) and remedial procedure for complication (OR = 1.35, 95% CI 0.51-3.69, p= 0.657) between the groups. Compared with that of MC patients, EVT patients had a greater likelihood of functional independence (mRS score 0-2) at discharge (OR = 1.68, 95% CI 1.142.50; p = 0.008) and at 2years (OR = 1.89, 95% CI 1.20-3.00; p = 0.005), a lower incidence of 2-year all-cause mortality (OR = 0.54, 95% CI 0.31-0.93; p = 0.023) and a similar rate of retreatment (OR = 1.00, 95% CI 0.23-4.40; p = 1.000). Conclusion: Clinical outcomes after treatment for ruptured AComA aneurysms appear to be superior to those after treatment with MC, with fewer overall procedure-related complications and no increase in the retreatment rate. Additional studies in other countries are needed to verify these findings. [ABSTRACT FROM AUTHOR]

Aim. To analyze and determine the optimal indications for microsurgical operative interventions in the shortest possible time from the subarachnoid hemorrhage onset to prevent anterior communicating artery (AcomA) aneurysm re-rupture and bleeding. Materials and methods. 280 patients with brain aneurysms were examined at the Uzhhorod Regional Center of Neurosurgery and Neurology and the City Hospital of Urgent and Emergency Medical Care under Zaporizhzhia City Council. Among them, 98 patients (48 males and 50 females) were diagnosed with AcomA aneurysms. The age of patients with AcomA aneurysms was from 20 to 72 years (mean age 47.8 ± 11.0 years). Aneurysms were verified using head and neck computed tomography angiography (a Toshiba Astelion scanner, 2016, No. 4СС162106), selective cerebral angiography (an angiography system General Energy Optima IGS 330, 2019, No. 80071260314), and brain magnetic resonance angiography (an i_Open 0,36 T magnetic resonance tomograph, 2005, No. Toc102633006). Cerebral hemodynamics was assessed using transcranial dopplerography (“Philips HD7” ultrasound diagnostic system, 2014, No. 69935). Results. In the first three days after the onset of subarachnoid hemorrhage, 18 (18 %) patients were admitted with ruptured aneurysms of this location, 62 (62 %) within 4–8 days, 12 (12 %) patients within 9–14 days, later than 14 days – 6 (6 %). All 98 patients underwent microsurgical clipping of AcomA aneurysms. Due to severe cerebral edema, decompressive craniectomy was performed in two patients. The results of surgical treatment were evaluated according to the modified Rankin scale at the time of hospital discharge and were as follows: in 65 (65 %) patients – good; in 18 (18 %) – moderate disability; in 4 (4 %) – serious disability. 11 (11 %) patients died. Conclusions. The treatment outcomes in patients with ruptured AcomA aneurysms were significantly dependent on factors related to increased risk of re-rupture: the presence of large-sized intracerebral hematoma, the aneurysm index exceeding 2, and multi-chamber aneurysm.

It is important to understand the patient's vascular anatomy before treating cerebral aneurysms. The middle artery of the corpus callosum is one of the least common variations of the anterior communicating artery (AComA) complex. We describe the case of a 59-year-old woman who suffered a subarachnoid hemorrhage due to an AComA complex aneurysm that had ruptured. Fluorescein injection during the aneurysm clipping procedure revealed a partial obstruction of the middle artery, requiring clip repositioning. The vascular variations that patients may exhibit must be considered in aneurysm clipping surgery. [ABSTRACT FROM AUTHOR]
