Successful Nonsurgical Treatment of a Radial Artery Pseudoaneurysm following Transradial Coronary Angiography

Abstract

Transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. Radial artery pseudoaneurysms present as a rare complication of transradial catheterization. Although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the TR Band^® (Terumo Medical Corporation, Somerset, NJ) is a novel efficient technique only suggested by a few reports. We describe a 34-year-old man, who underwent transradial primary coronary angiography due to ST-elevation myocardial infarction. Two months later, he noticed a pulsatile mass on his hand where the catheterization was done. Ultrasonography proved the diagnosis of a pseudoaneurysm. Consequently, a TR Band^® was applied to compress the mass. Interestingly, 24 hours later, ultrasonography confirmed a thrombosed pseudoaneurysm and the pulsatile mass had completely disappeared gradually without recurrence at 2 months’ follow-up. Hence, this case report aims to propose the TR Band^® as an effective noninvasive method for the treatment of pseudoaneurysms following catheterization.
