Current treatment methods for postcatheterization pseudoaneurysms.

Abstract

Pseudoaneurysms are a recognized complication of arterial catheterization. Until recently, the standard method of treatment has been surgical. The past decade has seen the introduction of several minimally invasive techniques that have largely replaced surgical treatment of pseudoaneurysms. The most commonly used methods are ultrasound-guided compression and percutaneous injection of thrombin into the pseudoaneurysm. This review article describes all the methods available for the treatment of postcatheterization pseudoaneurysms, presents results from the largest published series, and discusses the relative merits of each technique.
