摘要

Introduction

Although stentrievers (SRs) are widely used for mechanical thrombectomy (MT), the impact of device dimensions on optimizing reperfusion outcomes in high clot burden cases is unclear. Our study aimed to investigate the effect of SR size on angiographic and clinical outcomes in patients with acute terminal internal cerebral artery (TICA) occlusion.

Methods

We analyzed ROSSETTI registry data to compare technical and clinical outcomes of TICA occlusion patients treated with MT without rescue therapy, according to SR diameter and length: 6 × 41–50 mm, 6 × 20–40 mm, and <6 × 20–50 mm. The first-pass effect (FPE) was defined as achieving a TICI2c‑3 after a single pass.

Results

We included 491 patients, 240 (41.5%) in 6 × 41–50 group, 117 (20.2%) in 6 × 20–40 group, and 134 (23.2%) in < 6 × 20–50 group. The MT procedure time for the 6 × 41–50 group was shorter, but the FPE rate was similar across all groups. The highest final mTICI 2c‑3 rate was in 6 × 41–50 group (81.2%), compared to 6 × 20–40 group (68.4%) and 4–6 × 20–50 group (72.4%) (p = 0.016). Distal catheter use was associated with final mTICI 0-2b (62% of patients). Clinical outcomes were similar between the groups. Larger diameter and longer length of the SR, as well as not using an intermediate catheter, were independent predictors of final mTICI 2c‑3. The use of 6 × 41–50 SRs (OR 1.64, 95% CI 1.06–2.52; p = 0.024) and distal catheter use (OR 0.62, 95%CI 0.40–0.96; p = 0.034) were independent predictors of final mTICI 2c‑3.

Conclusions

Use of longer and larger SRs in acute intracranial TICA occlusion improves final reperfusion rate.
