Real-World Thrombectomy Using the Sofia Catheter

Abstract

Objective: To study the safety and performance of real-world thrombectomy using the SOFIA Catheter in our comprehensive stroke center.

Methods: We conducted a cohort study from a prospective clinical registry of consecutive stroke patients treated by mechanical thrombectomy between March 2016 and September 2017. Baseline clinical and imaging characteristics, recanalization rates, complications, and clinical outcomes were analyzed.

Results: Among the 140 patients included, 54 were treated using aspiration first, 64 were treated using aspiration and stent-retriever straightaway, and 22 were treated with SOFIA as a rescue device. Successful recanalization (Modified Thrombolysis In Cerebral Infarction score 2b/3) was achieved in 82.1% patients and good outcomes in 34.3%. Symptomatic intracranial hemorrhage occurred in 7.1% and mortality in 25%.

Conclusions: In our single-center experience, thrombectomy using the SOFIA as an intermediate or aspiration catheter provided high recanalization rates under everyday conditions.
