title: Vascular injury after lumbar discectomy mimicking appendicitis: Report of a case.
abstract: Right lower quadrant pain after a lumbar discectomy is a rare condition. We report on a 29-year-old man who developed right lower quadrant pain 12 h after lumbar discectomy due to the formation and rupture of a right iliac artery pseudoaneurysm. The diagnostic laparoscopy was done under the impression of acute appendicitis but showed a retroperitoneal hematoma. An emergency abdominal computed tomography confirmed a right iliac artery pseudoaneurysm rupture. We performed a transarterial embolization with multiple metallic coils in the aneurysm cavity and connected the proximal and distal right internal iliac artery because his hemodynamics became progressively unstable. In this article, in addition to presenting the clinical course of an unusual case, we also wanted to emphasize that patients with right lower quadrant pain could be presenting an early sign of pseudoaneurysm formation and rupture after a lumbar discectomy.
