Neurointerventional procedures using sheathless 8 Fr Optimo balloon guide catheter via transradial access: A single-center experience with 100 cases.

ObjectiveThis study aimed to evaluate the feasibility and safety of neurointerventional procedures performed via transradial access (TRA) using a sheathless 8 Fr Optimo balloon guide catheter (BGC).MethodsWe retrospectively analyzed 100 consecutive neurointerventional procedures performed via TRA using a sheathless 8 Fr Optimo BGC at a single center. Technical success was defined as the successful delivery of the BGC to the target vessel without conversion to an alternative access site or catheter system, along with the completion of the planned procedure.ResultsA total of 100 procedures were performed in 95 patients (median age: 75 years; 63% male). The most common interventions were aneurysm coiling or flow diversion (45%) and carotid artery stenting (36%). Target vessels for BGC placement included the right carotid (59%), left carotid (31%), right vertebral (4%), and left vertebral (6%) arteries. The median BGC navigation time was 12 min (interquartile range: 7-20). Technical success was achieved in 95% of procedures. In five cases, conversion to transulnar, transbrachial, or transfemoral access was required; nevertheless, all planned procedures were completed successfully. Balloon inflation was utilized in 37% of procedures for distal embolic protection, rupture management, or device delivery support. No major access-related complications were observed. Symptomatic non-access-related periprocedural complications occurred in 3% of cases. The overall mortality rate was 2%.ConclusionsNeurointerventional procedures performed via TRA using a sheathless 8 Fr Optimo BGC appear to be feasible and safe, offering a high technical success rate and a low incidence of access-related complications.
