Pseudoaneurysm of the Radial Artery on the Hand Secondary to Stabbing

Abstract

Pseudoaneurysm of the radial artery is extremely rare. It usually occurs secondary to trauma, interventional procedures, and infections. Symptoms occur due to mass effect by the pseudoaneurysm, digital ischemia, or nerve suppression. B-mode and color Doppler ultrasonography are the first choice in diagnosis. The pathognomonic ultrasound sign of pseudoaneurysm is the turbulent flow, which is called the "ying-yang'' sign. Bandages, ultrasound probe compression, ultrasound-guided thrombin injection, covered stents, and surgical ligation can be used in treatment. In here, we present the case of a 28-year-old woman who developed a radial artery pseudoaneurysm after a stabbing injury in her hand and discuss the radiological and treatment options.
