A radial artery pseudoaneurysm following transradial access treated successfully with external compression dressing – A very rare complication

abstract Transradial approach for coronary angiography was first described in 1989. Coronary interventions through radial approach are becoming more frequent and preferred procedure now a days. There are many advantages of using radial route, which includes less puncture site related complications, less bleeding, early ambulation, early discharge and low cost. Although like other procedures, it is not free of complications. Rare vascular complications may include radial artery spasm, dissection, occlusion, perforation and compartment syndrome. Here we present an unusual case of radial artery pseudoaneurysm. Although pseudoaneurysm is a well-known complication related to femoral access (0.2 to 3%), it is very infrequent (0.009%) in case or radial access. Usually after the catheter or sheath is removed, a clot is formed at the arteriotomy site that typically seals the lumen and prevents the continuous egress of blood. If this thrombus is inadequate, a pseudoaneurysm, that communicates with the arterial lumen can form external to the artery. Till date very few such cases have been reported for which recommended is surgical management of the pseudoaneurysm. Although recently there have been reports of successful nonsurgical treatment in some patients. In this report, we present an efficient, safe and noninvasive management protocol using modification of transradial band (TR Band) application technique with combination of ultrasonography (USG) guided compression of pseudoaneurysm. The approach is cost-effective and efficient and ensures correction without occlusion of the radial artery.
