Thrombus Visualization Using Low-Pressure Contrast Injection via a Small-Bore Aspiration Catheter in M2 Thrombectomy: A Technical Note

Key Points

Visualizing thrombus with low-pressure contrast injection improves procedural workflow, enhancing recanalization rates.
Achieving first-pass recanalization success is key, potentially reducing the risk of distal embolization during M2 thrombectomy.
This technique employs an aspiration catheter to ensure safety during thrombus visualization and improves effectiveness in procedures.
Preliminary evidence supports further investigation of this method in larger patient cohorts for broader applicability.

Abstract

This novel technique offers a simple, safe, and effective method for direct thrombus visualization in M2 occlusions. By utilizing the intermediate catheter for controlled, low-pressure contrast injection, it may reduce the risk of distal embolization and simplifies the procedural workflow, potentially enhancing the rate of 1st-pass recanalization success. This technical note introduces the concept and provides preliminary evidence supporting further investigation and validation in larger patient cohorts.
