A case report of iatrogenic radial artery true aneurysm

Abstract

True aneurysm is dilatation of an artery which consists of all layers of the arterial wall. True radial artery aneurysms are very rare. The most common cause of radial artery aneurysm is iatrogenic trauma. Here, we report a case of iatrogenic true radial artery aneurysm. A 38-year-old male with a history of right radial artery cannulation for anticoagulant therapy to treat right leg deep venous thrombosis presented to our outpatient department with a complaint of swelling on the radial side of the volar aspect of the right arm. He was treated conservatively with steroids, but symptoms did not subside. Doppler ultrasound and computed tomography scan suggested true radial artery aneurysm. In view of pseudoaneurysm, surgical plan was made. During surgery, the aneurysm seemed to be involved in all the vessel layers. The aneurysm was excised, and ligation of both the ends was done. Anastomosis was not done owing to good flow in the distal part from the ulnar artery and damage to a long segment of the radial artery. Patients on anticoagulants are at a risk of aneurysm formation than patients who are not. It can be diagnosed clinically and radiologically.
