Outcomes of stent-assisted coil embolization of intracranial aneurysms with a small parental vessel diameter.

ABSTRACT: BackgroundStent-assisted coil embolization (SACE) is widely used for treating cerebral aneurysms, particularly bifurcation aneurysms. Although stents are typically indicated for parent vessels larger than 2 mm, their use in small-diameter vessels (<2 mm) hasn't been extensively studied. This study evaluates the safety of SACE with small-diameter vessels.MethodsThis retrospective study analyzed 324 patients who underwent SACE between 2010 and 2023. Patients were divided into the small-diameter (SD) group (<2 mm, n = 100) and the normal diameter (ND) group (> 2 mm, n = 224). Perioperative ischemic complications and their risk factors were compared between the two groups.ResultsIntraoperative thrombi occurred in 6 patients (6.0%) in the SD group, with 4 (4.0%) asymptomatic and 2 (2.0%) transi
