This study looked at patients who underwent mechanical thrombectomy to treat strokes. The researchers compared a carrier delivery-assist catheter against standard microcatheter techniques used to remove blood clots. The data came from 15 U.S. stroke centers and included 211 procedures using the carrier device. A separate look at 242 patients from one center compared the carrier tool to standard methods.
The main findings showed that using the carrier catheter reduced the time from needle puncture to clot engagement. In the single-center analysis, this time was shorter with the carrier tool. The rate of successful clot removal was also numerically higher with the carrier device in that same group. However, the overall multicenter data did not report specific comparisons for these primary outcomes.
Safety was a key concern. The study reported rates of bleeding in the brain tissue and under the lining of the brain. No increased complications were found with the carrier catheter in the single-center analysis. The researchers noted that the carrier tool helps navigate large catheters more easily. They also found that vessel shape did not affect the main results. Because this is a retrospective study, the team says more research is needed before changing standard practice.
