Abstract
IntroductionThis study is the first multicentric report on the safety, efficacy, and technical performance of utilizing a BMX™ 7F large bore (0.081” inner diameter) access catheter (LB‐AC) in neurovascular interventions.MethodsData were retrospectively collected from 7 sites in the United States for neurovascular procedures via large bore 0.081” inner diameter access catheter (Benchmark BMX81, Penumbra, Inc.). The primary outcome was technical success, defined as the access catheter reaching its target vessel. Safety outcomes included periprocedural device‐related and access site complications.ResultsThere were 90 consecutive patients included. The median age of the patients was 63 years (IQR: 53, 68); 53% were female. The most common interventions were aneurysm embolization (33.3%), carotid stenting (12.2%), and AVM embolization (11.1%). Challenging anatomic variations included severe vessel tortuosity (8/90, 8.9%), type 2 aortic arch (7/90, 7.8%), type 3 aortic arch (2/90, 2.2%), bovine arch (2/90, 2.2%), and severe angle (<30°) between the subclavian artery and target vessel (1/90, 1.1%). Technical success was achieved in 98.9% of the cases (89/90), with 6 cases requiring a switch from radial to femoral (6.7%). There were no access site complications or complications related to the 0.081” catheter. Two postprocedural complications occurred (2.2%), unrelated to the access catheter.ConclusionThe BMX™ 7F LB‐AC was safe and effective in both radial and femoral access across a wide range of neurovascular procedures, achieving high technical success without any access site or device‐related complications.
