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-yearold 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. © 2017,tehran heart center. all rights reserved.
