Treatment of recurrent radial artery pseudoaneurysms by prolonged mechanical compression.

Nazer B, Boyle A.

As radial artery pseudoaneurysm (PA) is a rare complication of transradial catheterization, data on their management are sparse. Here, we report the case of a 77-year-old woman who underwent right transradial diagnostic cardiac catheterization, and subsequently developed a symptomatic PA. She underwent initial treatment with 20 minutes of mechanical compression with a Hemoband (Hemoband Corporation) with initial success. Three weeks later, she developed recurrence of her PA, and was treated with 24 hours of mechanical compression, wearing the Hemoband as an outpatient, with sustained resolution of the PA confirmed by ultrasound 1 month later, and no neurologic or further vascular complications. In addition to demonstrating that an initial PA as well as its recurrence can be treated with prolonged mechanical compression, we review the literature regarding radial artery PAs and their treatment.
