Department of Preventive Medicine and Public Health, University of Catholic Kwandong College of Medicine, Gangneung, Korea.
Stents are increasingly used for coiling difficult aneurysms, to reduce the risk of recurrences, or to modify blood flow. Currently, available bifurcation aneurysm models are ill-suited to assess stent performance before clinical use. We designed a new animal model of wide-neck canine Y-type bifurcation aneurysm (such as middle cerebral artery (MCA) bifurcation) and previously reported one of T-type (such as basilar bifurcation).

Impact of ischemic stroke topography on early clinical outcome of basilar artery occlusion: a retrospective study.
Eur Radiol
October 2024
Department of Diagnostic and Interventional Neuroradiology, Klinikum Rechts der Isar, School of Medicine, Technical University of Munich, Munich, Germany.
Article Synopsis
- Basilar artery occlusion (BAO) can result from either embolism or thrombosis due to basilar stenosis, with the latter (BAOS) leading to worse clinical outcomes compared to embolic occlusions (BAOE).
- A study involving 199 patients found that specific brain regions, particularly the medulla oblongata and inferior pons, played a critical role in predicting unfavorable early outcomes after BAO, with BAOS patients having larger infarct volumes.
- Successful reperfusion was more common in BAOE patients, indicating that differences in occlusion type and brain stem infarct patterns significantly impact recovery and outcomes after treatment.

- - Results showed that 96% of patients achieved complete thrombus resolution within two weeks, with cervical segment internal carotid arteries being the most affected; common underlying conditions included atherosclerosis and atrial fibrillation.
- - Importantly, no major bleeding complications arose from anticoagulant use, leading to favorable functional outcomes post-treatment as assessed by the modified Rankin scale.
Successful shrinkage of a recurrent partially thrombosed symptomatic large basilar tip aneurysm using a Target 3D Coil.
Surg Neurol Int
March 2024
Department of Neurosurgery, Graduate School of Medicine, Kobe University, Kobe, Japan.
Article Synopsis
- Standalone coil embolization is often ineffective for partially thrombosed intracerebral aneurysms (PTIA) due to risks of recurrence if coils migrate into the thrombus.
- A 63-year-old male with a history of a basilar artery aneurysm underwent successful coil embolization using a Target 3D Coil, leading to complete disappearance of the aneurysm and improved nerve function after five years.
- The design of the Target 3D Coil likely prevented migration into the thrombus, aiding in the successful resolution of the aneurysm.

Department of Neurosurgery, Wessex Neurological Centre, University Hospital Southampton, Tremona Road, Southampton, SO16 6YD, UK.
Article Synopsis
- - The study investigates basilar artery perforator aneurysms (BAPAs), which are rare compared to regular aneurysms, focusing on their presentation, imaging features, and outcomes.
- - Researchers analyzed cases of BAPAs from a neurovascular database and found that out of 739 patients with subarachnoid hemorrhage, 9 had BAPAs, which were more common in males but showed similar severity to non-perforator aneurysms.
- - Most BAPAs were initially missed on CT angiography, but showed significant enhancement on vessel wall imaging; the majority spontaneously thrombosed with conservative management, leading to no complications or rebleeds.
