Abstract

Abdominal vascular injury after blunt trauma does not occur very frequently. Penetrating trauma is the most common cause (90%) of abdominal vascular injury. A 57-year-old male presented with abdominal pain and color change of the right lower leg after blunt trauma. The physical examination showed rigid tenderness in the entire abdomen and no pulse in the right femoral artery. Computed Tomography (CT) demonstrated the acute aortic dissection, which extended from the infrarenal aorta to the iliac artery and there was embolic occlusion below the right common iliac artery. He underwent endarterectomy after thrombectomy, fasciotomy and small bowel segmental resection. A 65-year-old male presented with abdominal pain after an auto-bicycle crash. On the physical examination, there was tenderness and rebound tenderness noted on the entire abdomen. The CT done outside our hospital demonstrated an intramural hematoma around the descending aorta. He underwent small bowel and sigmoid segmental resection and S-colostomy. On day 1 after operation, he complained of sudden abdominal pain. He then developed the signs of acute liver and renal failure. His condition deteriorated rapidly with conservative management, and he died on day 2.
