Abstract

Background

Basilar artery perforator aneurysms (BAPAs) are a rare subset of intracranial aneurysms, accounting for <1% of cases. The natural history of BAPAs is unknown, and a standardized management approach is lacking. This report presents the largest cohort of surgically treated BAPAs to date, addressing gaps in the literature and guiding management strategies.

Methods

A single-center retrospective analysis was conducted utilizing a prospectively maintained, IRB-approved database, which included a series of seven consecutive patients treated for BAPAs. The dataset included patient characteristics, surgical details, postoperative outcomes, complication rates, and imaging and clinical follow-up data. It also featured case illustrations.

Results

A total of seven patients were included, all presenting with subarachnoid hemorrhage. The median age was 60 years (IQR: 56.5, 69), and 57% were female. The most common location of the perforators was mid-basilar (43%). Five cases (71.4%) had aneurysms that went undetected on the initial angiogram. All patients underwent microsurgical clipping as their treatment. Post-surgery, oculomotor nerve palsy was observed in four patients (57.1%), and three (42.8%) experienced hemiparesis, which improved during their hospital stay. Follow-up diagnostic angiograms revealed a complete aneurysm occlusion of all aneurysms with no residual filling.

Conclusion

Microsurgical clipping is an effective treatment option for BAPAs when observation and endovascular interventions are not feasible. Treatment decisions should be guided by presentation, aneurysm characteristics, and overall risk profile. A multicenter registry is needed to establish standardized management guidelines. A multidisciplinary, tailored approach is recommended to optimize individual patient outcomes.

期刊介绍: Neurochirurgie publishes articles on treatment, teaching and research, neurosurgery training and the professional aspects of our discipline, and also the history and progress of neurosurgery. It focuses on pathologies of the head, spine and central and peripheral nervous systems and their vascularization. All aspects of the specialty are dealt with: trauma, tumor, degenerative disease, infection, vascular pathology, and radiosurgery, and pediatrics. Transversal studies are also welcome: neuroanatomy, neurophysiology, neurology, neuropediatrics, psychiatry, neuropsychology, physical medicine and neurologic rehabilitation, neuro-anesthesia, neurologic intensive care, neuroradiology, functional exploration, neuropathology, neuro-ophthalmology, otoneurology, maxillofacial surgery, neuro-endocrinology and spine surgery. Technical and methodological aspects are also taken onboard: diagnostic and therapeutic techniques, methods for assessing results, epidemiology, surgical, interventional and radiological techniques, simulations and pathophysiological hypotheses, and educational tools. The editorial board may refuse submissions that fail to meet the journal''s aims and scope; such studies will not be peer-reviewed, and the editor in chief will promptly inform the corresponding author, so as not to delay submission to a more suitable journal. With a view to attracting an international audience of both readers and writers, Neurochirurgie especially welcomes articles in English, and gives priority to original studies. Other kinds of article - reviews, case reports, technical notes and meta-analyses - are equally published. Every year, a special edition is dedicated to the topic selected by the French Society of Neurosurgery for its annual report.
