A Case of Graft Infection Treated by Laparoscopic Abscess Drainage and Omental Plombage

Abstract

A 77-year-old man presented with of claudication of both legs. Since computed tomography (CT) showed a high occlusive lesion of the abdominal aorta, aorto-bilateral femoral artery bypass was performed. The patient's postoperative course was uncomplicated, and he was discharged home from the hospital. However, six months after the surgery, he visited a nearby hospital because of lower back pain and was transported by ambulance to our hospital due to a suspected iliopsoas muscle abscess on CT. He was diagnosed with a left retroperitoneal abscess with graft infection, and emergent laparoscopic abscess drainage and omental plombage were performed. Antimicrobial drugs were administered for a long time. Fortunately, he went home again and has been monitored without recurrence. Though most graft infections, which are refractory and may progress to systemic infection, need graft removal and revascularization, this patient achieved a successful outcome at one year without recurrent infection with laparoscopic abscess drainage and omental plombage.
