ABSTRACT Background and Purpose Large‐bore aspiration catheters (LBACs) are used for thrombectomy in large vessel occlusion (LVO), either as a standalone direct first‐pass technique or combined with stent retriever (ASR). LBAC design may influence ASR efficacy. We compared the safety performance of novel MIVI Q segmental catheter well‐established SOFIA device thrombectomy. Methods analyzed data from Registry cOmbined vS SinglE Thrombectomy TechnIques registry consecutive patients anterior circulation LVO outcomes those treated first‐line using (Q5 Q6) (5F 6F Plus) catheters. Demographic, clinical, angiographic, clinical outcome (24‐h National Institute Health Stroke Scale [NIHSS] modified Rankin score at 3 months) were compared. Results Of 853 patients, 155 (18.2%) 698 (81.8%) After adjusting age, sex, NIHSS baseline, tPA use, site occlusion, anesthesia type, diameter length SR, group was comparable to terms effect successful final recanalization safety. However, had shorter mechanical time (20 [10–45] min vs. 33 [20–51] min; odds ratio [OR] = 7.4, 95% confidence interval [CI]: 1.1–14; p 0.021) lower rate symptomatic intracerebral hemorrhage (3.3% 8.8%; OR 3.59, CI: 1.45–10.9; 0.011). Conclusions In neurothrombectomy, not superior achieving complete first‐passage recanalization; however, procedural times intracranial hemorrhage.
