Femoral Access-Assisted Balloon Trapping: A Novel Approach to Managing Kinked Catheter During Transradial Coronary Intervention-A Case Report.

Catheter kinking is a rare but significant complication of trans-radial coronary interventions, often caused by arterial tortuosity, vessel spasm, or improper catheter manipulation. We present a case of catheter kinking that occurred during coronary engagement in a transradial procedure, which could not be resolved using conventional techniques. Given the failure of guidewire advancement and deep inspiration maneuvers, a femoral access-assisted balloon trapping technique was employed. This method allowed for the successful retrieval of the kinked catheter while minimizing vascular trauma and ensuring procedural completion. Catheter kinking during trans-radial coronary interventions poses technical challenges requiring tailored management strategies. This case underscores the effectiveness of femoral access-assisted balloon trapping technique as a viable and minimally invasive solution. Increased awareness and preparedness for such complications can enhance procedural success and patient safety.
