Clinical Study of Symptomatic Nonacute Intracranial Large Arterial Occlusion with Endovascular Recanalization
Funding This work was supported by the Hubei Provincial Health Commission Guidance Project (WJ2019F177).
Abstract
Objectives This study reported a single-center clinical trial of endovascular treatment for symptomatic nonacute occlusion of the intracranial large artery (NA-ILAO). The aim of this study was to evaluate the safety, feasibility, and clinical effect of simple balloon dilatation and stent implantation.
Methods The patients diagnosed with symptomatic NA-ILAO were enrolled. A total of 40 cases were included in this study. While recanalization failed in 4 patients, it was successful in 36 patients, who were then divided into two groups for further analysis: balloon dilatation group (n = 24) and stent implantation group (n = 12). The perioperative complications, clinical outcome, and follow-up results were analyzed.
Results Perioperative complications in the stent implantation group were significantly higher than those in the simple balloon dilatation group (p < 0.05). There were 21 and 10 cases of 90-day good clinical outcome (modified Rankin scale [mRS] ≤ 2) in the balloon and stent groups, respectively (p = 0.518). All patients with successful recanalization underwent digital subtraction angiography (DSA) or CT angiography (CTA) during an average follow-up of 14 months. There were two cases of restenosis in the balloon dilatation group and one in the stent implantation group (p = 1.000). There were two cases of re-occlusion in the stent group and none in the balloon dilatation group (p < 0.001). Stroke recurred in two cases in the stent group and in one case in the simple balloon dilatation group (p = 0.013).
Conclusion Endovascular recanalization is safe and feasible for patients with symptomatic NA-ILAO. Compared with stent implantation, simple balloon dilation may be a better recanalization method, but larger randomized controlled trials are needed to confirm it.
