Abstract

This study presents a rare case of an unruptured basilar artery trunk aneurysm treated with telescoping LEO+ stents and provides a systematic review of current endovascular strategies for this lesion subtype. By illustrating an application of an established overlapping braided-stent strategy in a rare location, the report adds to the limited available evidence on treatment options for this lesion subtype.
A systematic review was performed according to PRISMA 2020 guidelines across PubMed, the Cochrane Library, and Embase. The search identified 247 records, of which 12 studies met the inclusion criteria. Extracted data included patient demographics, aneurysm morphology, treatment modality, follow-up duration, angiographic outcomes, and complications. Additionally, we report a case involving a 65-year-old man with an unruptured basilar artery trunk aneurysm treated with a telescoping LEO+ stent construct.
The selected studies encompassed 101 patients with unruptured basilar trunk aneurysms. Mean age ranged from 37 to 60.5 years. Endovascular strategies varied, with stent-assisted coiling, primary coiling, and flow diversion being the most frequently used. Complications included subarachnoid hemorrhage, ischemic stroke, infarction, and aneurysm perforation. The overall certainty of the available evidence was very low. Our case illustrates the successful treatment of a small saccular basilar trunk aneurysm using telescoping LEO+ stents with the intention of achieving a flow-diverting effect while seeking to limit the risks associated with coiling-such as iatrogenic perforation-and with posterior-circulation flow diverters, which may compromise perforator arteries.
In this single case, telescoping LEO+ stents represented a feasible endovascular option for a small basilar artery trunk aneurysm. Whether this technique reduces procedural risks relative to conventional methods cannot be determined from a single observation, and its efficacy and safety remain to be established in larger, controlled studies.
