Background:
Coronary angiography and intervention through transradial approach is becoming default approach because of infrequent local site complications. Although pseudoaneurysm is a well described complication for femoral access, it is extremely rare in transradial access.
Case report:
Our patient was 68-year old female who had presented with pulsatile, painful, and gradually increasing swelling over lower part of right forearm near wrist joint for past 8-weeks following coronary angiography through right radial route. Swelling did not resolve following manual compression. It was diagnosed as pseudoaneurysm arising from right radial artery by duplex ultrasound. It was successfully excluded by deploying 3.5x18mm Graftmaster covered stent (Abott Vascular, USA) through right transbrachial route. Ultrasonography next day revealed partially thrombosed and completely excluded pseudoaneurysm with swelling completely disappearing at 6 weeks with patency maintained at one year.
Conclusion:
With increasing use of transradial access, more cases of radial pseudoaneurysm are likely to surface which can be prevented following a proper haemostatic protocol. To best of our knowledge, it is first ever report of percutaneous endovascular exclusion using covered stent of radial pseudoaneurysm through transbrachial approach.
