Aneurysms of the A1 segment of the anterior cerebral artery (A1A) are rare and challenging to treat. Less information is available regarding their management by endovascular approach. We evaluated our experience of endovascular treatment in 15 patients with unruptured A1As. We retrospectively reviewed unruptured A1As treated by embolization at our hospital. The clinical data and angiographic results were reviewed. A special technique involving shaping microcatheter tips was used for catheterization. From September 2009 to December 2012, 15 patients presenting with unruptured A1As were identified. All the patients were treated by selective embolization including five patients with balloon-assisted coiling (BAC) or stent-assisted coiling (SAC). These adjunctive techniques were used to catheterize the sac safely or to protect a branch at the neck. According to the location and direction of the aneurysm, "Z-shaped", "S-Shaped" or "U-Shaped" microcatheter tip shaping was used for microcatheter positioning and stabilization. All patients showed an excellent clinical outcome. A complete aneurysm occlusion was obtained in all the patients. Endovascular treatment of A1As is feasible and associated with good results. Because of their location and close relationship with perforators, endovascular treatment of A1As sometimes requires the use of BAC or SAC. The microcatheter tip shaping technique is very important for coiling. Our results suggest that endovascular treatment is a suitable therapeutic option for unruptured A1As when the aneurysm size is optimal for embolization.

Unlabelled: Brain arteriovenous malformations (AVMs) pose a significant treatment challenge, with current options including microsurgical resection, endovascular embolization, radiosurgery, or combinations thereof. Here, we present our experience with a curative strategy combining complete endovascular treatment followed by microsurgical resection under the same anesthesia session, without relying on a hybrid operating room.
Methods: We reviewed consecutive AVM patients who underwent endovascular treatment (EVT) and microsurgical resection (MS) in a single anesthesia session (COMBI-AVM protocol) from December 2017 to July 2022.
Posterior clinoidectomy in the subtemporal trans-tentorial approach for a basilar bifurcation aneurysm: technical note.

Departments of Neurosurgery, Interdisciplinary Graduate School of Medicine and Engineering, University of Yamanashi, Chuo, Japan. Electronic address:
Objective: Although the endovascular approach has emerged as the first-choice treatment for basilar bifurcation aneurysms these days, there are situations where direct surgery remains necessary. Among several surgical approaches, the subtemporal trans-tentorial approach can be adapted for low-positioned aneurysms projecting posteriorly. Since surgeons observe the aneurysm from a lateral perspective in this approach, the posterior clinoid process (PCP) does not usually obstruct the surgical field, and posterior clinoidectomy in this approach has not been reported to date.

Background: With Africa's population growth and an epidemiological shift from communicable to non-communicable diseases, there is an urgent need to expand vascular surgery capacity across the continent. Despite a high disease burden, Sub-Saharan Africa contributes less than 1% of the global surgical research, with significant challenges in surgical infrastructure, access to consumables, and limited research output. This study assesses the publication output of African authors in the top five vascular surgery journals and explores trends in African vascular research.

Background: Cervical carotid dissections are a significant cause of thromboembolic events in young adults. While endovascular treatment is often used for large or enlarging lesions, smaller lesions are frequently managed conservatively. However, there is limited research on the hemodynamic differences between conservatively managed and endovascularly treated cervical carotid pseudoaneurysms.
