Abstract:

Background.—Iatrogenic trauma is the most common cause of pseudoaneurysm. Several treatment methods are now available, including surgical repair, direct compression with the assistance of ultrasound, and ultrasound-guided thrombin injection. Each of these treatments has its own risks and advantages.

Objective.—We sought to retrospectively assess the causes of pseudoaneurysm and the evolution of treatments and outcomes.

Results.— Ninety-three pseudoaneurysms were diagnosed at Dunedin Public Hospital between September 1994 and December 2005, the majority resulting from cardiac catheterization. Fifteen patients were treated with ultrasound-guided compression, with a success rate of 66%. Sixty-three patients were treated with ultrasound-guided thrombin injection, with a success rate of 95%. No major or lasting complications were observed with either compression or thrombin injection; however, delayed diagnosis and treatment may have serious consequences requiring surgical salvage.

Conclusions.—Ultrasound-guided thrombin injection is safe, effective, quick, and well tolerated by patients. It has become preferable to compression treatment and it is less invasive than surgical repair. Treatment should be given promptly upon diagnosis of the pseudoaneurysm rather than delaying with watchful expectation.
