Primary repair with in-situ interposition graft for infrarenal mycotic aortic pseudoaneurysm.
This is a case report of a pseudoaneurysm due to Salmonella aortitis in a 52 year old man. The condition is rare and represents one of the few cases reported in Malaysia. The diagnosis was made preoperatively by ultrasonography and computed tomography. This was confirmed at surgery where there was a 3 cm defect at the posterior wall of the aorta at L2/3 level. The aneurysmal sac extended to the retrocrural space at the 12th vertebra level cranially on the right side to the lower border of the 3rd lumbar vertebra caudally. It had a smooth fibrous wall and contained a mixture of organised haematoma and pus. At operation the aneurysm was excised, the affected region was carefully debrided and the aorta grafted with an in-situ in-lay graft. Antibiotic therapy was instituted until clinical response was evident, leukocytosis was reduced and blood culture was negative. However 4 months after surgery, the patient returned in irreversible shock and succumbed to disseminated intravascular coagulation secondary to massive upper gastrointestinal haemorrhage from an aortoduodenal fistula.
