Autologous Thrombin:A New Embolization Treatment for Traumatic Intrasplenic Pseudoaneurysm

The role of interventional radiology in the management of abdominal visceral artery aneurysms

Abdominal visceral artery aneurysms (VAA) include true and false aneurysms. The majority are asymptomatic and are discovered on cross-sectional imaging performed for unrelated clinical indications. With the maturation of techniques and devices used for embolization procedures and the treatment of aneurysms in other locations, most VAAs are now suitable for treatment by minimally invasive transcatheter techniques. The choice of technique used greatly depends on the local anatomy of the VAA and the experience of the interventional radiologist in complex vascular interventional techniques.

Ultrasound-guided thrombin injection of iatrogenic groin pseudoaneurysm: Doppler features and technical tips

The practice of angiographic procedures is increasing and, concomitantly, there has been an increase in the incidence of iatrogenic femoral pseudoaneurysms (PA). Ultrasound-guided thrombin injection is becoming the accepted gold standard in the treatment of PA. It is a cost-effective, safe and efficacious treatment that requires a short learning curve. The aim of this pictorial review is to demonstrate the Doppler and ultrasound features used to diagnose PA and those that help differentiate it from alternative diagnoses, and to describe the procedure of thrombin injection, highlighting technical tips and ways to avoid potential complications.

Current treatment methods for postcatheterization pseudoaneurysms

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.
