successful nonsurgical treatment of a radial artery pseudoaneurysm following transradial coronary angiography

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.
