ABSTRACT
BACKGROUND:
Super large-bore aspiration (SLBA) has shown high rates of complete clot ingestion.OBJECTIVE:
To report the initial clinical feasibility, safety, and efficacy of this novel SLBA insert combination-super large-bore ingestion of clot (SLIC) technique for stroke.METHODS:
We performed a retrospective review of three comprehensive stroke center databases. The SLIC technique entails a triaxial assembly of an 8 Fr 0.106â³ Base Camp catheter, 0.088â³ catheter extender (HiPoint), and an insert catheter (Tenzing 8) that completely consumes the inner diameter of the 0.088â³ SLBA catheter. The HiPoint catheter is delivered over the Tenzing 8 to the face of the embolus, which is withdrawn, while aspirating through the Base Camp and HiPoint catheters as a single assembly.RESULTS:
Thirty-three consecutive patients with large vessel occlusion were treated with SLIC. The median age was 70 years (30-91) and 17 were male (51.5%). The median presenting National Institutes of Health Stroke Scale score and Alberta Stroke Program Early CT score was 21 (1-34) and 8 (5-10), respectively. There was 100% success in delivering the 0.088â³ catheter to the site of the occlusion. The successful revascularization rate (modified Thrombolysis in Cerebral Infarction (mTICI) score ≥2B) was 100% within a single pass in most cases (82%). Final mTICI ≥2C was achieved in 94.1% of occlusions, with 73.5% mTICI 3 recanalization. The rate of first pass effect in achieving excellent reperfusion (mTICI ≥2C) was 70.5%. There were no adverse events or postprocedural symptomatic hemorrhages.CONCLUSIONS:
Our initial experience with the SLIC technique resulted in achieving a first pass effect (mTICI ≥2C) in 70.5%. Navigation of the SLBA catheter extender over the Tenzing insert was successful and safe in this early experience.Palavras-chave
