Purpose: The purpose of this study was to review the microsurgical anatomy and clipping of ruptured anterior communicating artery (AComA) aneurysms and to plan and avoid complications before operation. Methods: A total of 523 cases of cerebral aneurysms admitted to the neurosurgery department of the Third Affiliated Hospital of Sun Yat-Sen University from September 2010 to October 2018 were analyzed retrospectively. Among them, 85 patients had ruptured AComA aneurysms. This study was limited to 85 of these cases, whose satisfactory preoperative angiographic diagnostic films can be retrieved from the hospital database system because of the need for detailed review. Results: We performed supraorbital eyebrow keyhole approach (SOEK) craniotomy in 85 patients to clip 85 AComA aneurysms, in the setting of subarachnoid hemorrhage (SAH). Patients’ mean age was (52.69 ± 9.94) years (range, 28–78 years). The proportions of small, medium and large aneurysms were 83.5%, 15.3%, and 1.2%, respectively. The average size of the aneurysms was (5.07 ± 2.36) mm. There were 77.8% of patients with inferior aneurysms and 81.3% of patients with superior aneurysms achieved good results. There was a significant correlation between A1 dominance and operation method (p

Anterior communicating artery (ACoA) aneurysm, accounts for 30%-35% of all the aneurysm making it one of the most common intracranial aneurysms.

Anterior communicating artery (ACoA) aneurysm, accounts for 30%-35% of all the aneurysm making it one of the most common intracranial aneurysms. Although the Pterional approach is considered as the safe and appropriate method in ACoA aneurysm surgery, temporalis atrophy and injury to a frontal branch of the facial nerve are few inexorable complications. With the advancement of minimally invasive surgery several modified approaches, such as the supraorbital eyebrow incision approach, the minipterional approach, the mini-supraorbital approach, and the lateral supraorbital approach has been recently introduced and has been used as an alternative.

We summarize the treatment effectiveness and experience of a patient who underwent internal carotid balloon occlusion combined with Intermediate-flow bypass as a treatment for large-giant cavernous sinus segment internalcarotid artery (CS ICA) aneurysms. A 62-year-old woman presented with a large aneurysm on the right side of the cavernoussinus with dizziness for about two years and Oculomot or nerve palsy. An extra cranial intracranial (EC-IC) Intermediate-flow by pass using a radial artery bypass graft (RABG) and proximal balloon occlusion of the Right ICA were performed. The patient experienced no new neurologic deficit after this treatment. Follow up radiologic evaluations using Computed Tomography Angiography revealed complete aneurysm occlusion. For patients with large-giant CS ICA aneurysms, treatment of ICA occlusion combined with Intermediate-flow superficial temporal artery-Radial artery-middle cerebralartery bypass surgery was an effective and safe surgical strategy.
