摘要

支架辅助线圈栓塞术(SACE)被广泛用于治疗脑动脉瘤,特别是分叉性动脉瘤。虽然支架通常适用于大于2mm的血管,但它们适用于小直径血管(2mm, n = 224)。比较两组围手术期缺血性并发症及其危险因素。结果SD组6例(6.0%)患者术中出现血栓,无症状4例(4.0%),短暂症状2例(2.0%)。在ND组中,7例(3.1%)患者发生血栓,5例(2.2%)无症状,1例(0.4%)出现改良Rankin量表(mRS)恶化。SD组5例(5.0%)、ND组22例(9.8%)出现症状性缺血性并发症,其中mRS加重2例(2.0%)、7例(3.1%)。颈径>.5 mm被认为是围手术期缺血性并发症的危险因素。结论sace可以安全地用于SD母血管患者,且不会增加缺血性并发症。然而,SD组术中血栓发生率有升高的趋势,需要采取预防措施和及时干预。宽颈径> 5.5 mm被认为是SD组术中缺血性并发症的危险因素。

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

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%) transiently symptomatic. In the ND group, thrombi occurred in 7 patients (3.1%), with 5 (2.2%) asymptomatic and 1 (0.4%) experiencing worsened modified Rankin Scale (mRS). Symptomatic ischemic complications occurred in 5 patients (5.0%) in the SD group and 22 patients (9.8%) in the ND group, with 2 (2.0%) and 7 (3.1%) showing worsened mRS, respectively. A neck diameter > 5.5 mm was identified as a risk factor for perioperative ischemic complications.ConclusionSACE can be safely performed in patients with SD parent vessels without increasing ischemic complications. However, there was only a trend toward higher frequency of intraoperative thrombi in the SD group, highlighting the need for preventive measures and prompt intervention. Having a wide neck diameter > 5.5 mm was identified a risk factor for periprocedural ischemic complications in the SD group.

期刊介绍: Interventional Neuroradiology (INR) is a peer-reviewed clinical practice journal documenting the current state of interventional neuroradiology worldwide. INR publishes original clinical observations, descriptions of new techniques or procedures, case reports, and articles on the ethical and social aspects of related health care. Original research published in INR is related to the practice of interventional neuroradiology...
