NEW YORK (MedscapeWire) Apr 25 Percutaneous injection of bovine collagen into iatrogenic femoral artery pseudoaneurysm (FAP) induces clotting in about 98% of patients not responsive to ultrasound guided compression. More than 97% closed immediately, according to a study reported in the April 17 issue of the Journal of the American College of Cardiology.
"The percutaneous treatment of iatrogenic FAP, by injection with collagen, is an effective and safe strategy," write Karim Hamraoui, MD, and colleagues from the Heart Lung Center in Utrecht, Netherlands. "This method provides an excellent therapeutic alternative to the traditional surgical management."
This technique involves percutaneous injection of a biodegradable adhesive bovine collagen into the FAP via a 9F needle or 11F sheath guided by angiography from the contralateral site.
