“…Distal anterior cerebral artery (DACA) aneurysms represent about 1.5% to 9.2% of all aneurysms. [1][2][3][4][5][6][7] Most common location is at the bifurcation of the pericallosal and callosomarginal arteries. Most of the DACA aneurysms are found to be less than 5 mm in diameter, 5 and giant aneurysms are exceedingly rare.…”

“…Most of the DACA aneurysms are found to be less than 5 mm in diameter, 5 and giant aneurysms are exceedingly rare. 8 They are commonly associated with additional intracerebral aneurysms, occurring at rates as high as 20% to 25% 4 either MCA or ICA. The surgical treatment of patients with DACA aneurysms is difficult because of the narrow surgical field of vision, the presence of interhemispheric adhesions and location distal to A3 segment of ACA.…”

Introduction:The incidence of DACA aneurysms is between 1.5 to 9.0% of all intracranial aneurysms in the literature. Many of these are <5 mm in diameter. In this case series we report 30 cases of DACA aneurysms between 2009-2016, their presentations, associations and management including the use of neuronavigation system. Materials and Methods: Among 375 patients with cerebral aneurysms admitted between 2009-2016, 30 patients (8%) had DACA aneurysms, which were studied retrospectively. We analyse the specific clinical and radiological features, surgical strategies and associated anomalies with these DACA aneurysms. Results: Among the 30 patients with DACA aneurysms, 23 patients (76%) presented with subarachnoid hemorrhage, 7 patients (23%) had intracerebral hematoma, 1 had associated intraventricular haemorrhage and 1 patient had a thrombosed DACA aneurysm. 19 patients had Hunt & Hess grade 1, 8 had grade 2, 1 patient had grade 3 and 2 had grade 4. 23 of the DACA aneurysms (76%) were <5 mm in diameter, 6 were 5-15mm size and 1 had a giant aneurysm (>25mm). 2 patients died preoperatively due to recurrent bleeding. Out of the 28 patients operated, interhemispheric approach was used in 26 patients (92.85%), while pterional approach was used in 2 patients (7.14%). Neuronavigation was used in 16 cases. Postoperative complications included hemiparesis in 2 and death of 1 patient. Conclusion:The special neurovascular features, location of aneurysm and frequent association with anterior cerebral artery anomalies and other aneurysms must be taken into account when planning occlusive treatment of DACA aneurysms. Neuronavigation is helpful in planning craniotomy and precise localization.

“…Very few studies have compared the clinical features and treatment of MirAn patients, and most of them are case reports 1,4,7,8. To the best of our knowledge, only two other large-scale comparative studies on MirAn have been reported.…”

“…Most of these studies are case reports, and they were therefore unable to confirm or refute any hypotheses 1,2,4–8. Therefore, studies in larger cohorts of MirAn patients are needed to confirm the association between MirAn and its supposed risk factors, since a better understanding of the risk factors associated with MirAn could help with rupture prevention, diagnosis, treatment, and prognosis.…”

Background and objectiveMirror-like intracranial aneurysms (MirAn) occur symmetrically at the corresponding intracranial arteries and are a subgroup of multiple intracranial aneurysms. The aim of this study was to analyze the risk factors, treatment, and prognosis of MirAn.MethodsWe retrospectively analyzed 43 cases of MirAn diagnosed between January 2000 and December 2009. The control groups comprised patients with non-mirror-like multiple aneurysms (nMirAn) and single aneurysms (SingAn). Sex, age, localization of MirAn, hypertension, diabetes, smoking, and rupture were identified as potential risk factors for MirAn.ResultsThe male to female ratio of the MirAn patients was 1.0:5.1, which was significantly different from that of the nMirAn patients (1.0:1.9, P=0.037) and SingAn patients (1.0:1.3, P<0.001). There was no difference in age (P=0.8741), smoking (P=0.301), diabetes (P=0.267), or hypertension (P=0.874) between the MirAn and nMirAn patients. The aneurysms in 28 MirAn patients (65.1%) involved the internal carotid-posterior communicating arteries; in these patients, the rupture risk was significantly higher for larger aneurysms compared with smaller aneurysms (P<0.05).ConclusionMore women suffered from MirAn than nMirAn or SingAn. The most common MirAn sites were the internal carotid-posterior communicating arteries. Our results suggest that MirAn was not associated with age, smoking, hypertension, or diabetes.
