Hybrid repair for a complex infection aortic pseudoaneurysm with continued antibiotic therapy: A case report and literature review.

INTRODUCTION

Treatment of infection aortic pseudoaneurysm (PSA) is a great challenge to surgeons for 3 reasons: high mortality for rupture or threatened rupture; potential risk for infection of prosthetic material which probably bring a devastating result for patients; and long-term antibiotic therapy requirement. Endovascular repair is an alternative to open surgery for a less invasive, which is a trouble procedure for aortic PSA with complex aortic anatomy. The purpose of this article is to report the novel hybrid repair of an infection aortic PSA and antibiotics therapy.

CLINICAL FINDING: A 61-year-old man with complaints of repeated abdominal pain and fever for 3 months was admitted. He had a fever of 39.0°C and normal blood pressure. The blood leukocyte count was 14.9 × 10/L, C-reactive protein was 132 mg/L. There was no evidence for urinary tract infection. The small effusion was identified in bilateral thoracic cavity and pelvis cavity, and the severe lung function impairment was detected. Klebsiella pneumoniae was identified in blood cultures. Computer tomographic (CT) angiography showed a 6 cm × 6 cm aortic PSA involving bilateral renal arteries and a subhepatic inflammatory mass (identified by percutaneous puncture).

DIAGNOSIS: According to the symptoms, CT and lab test, the main diagnosis for this patient were: infective aortic PSA involving bilateral renal arteries, and Bacteremia with K pneumoniae.

INTERVENTION AND OUTCOMES: A hybrid procedure combined open surgical and endovascular was performed for managing the paravisceral infection aortic PSA in a 61-year-old man with high risk. To decrease the risk of graft infection, autologous saphenous vein graft was adopted, and long-term antibiotic therapy was used. At 2 years follow-up, the patient was in good clinical condition with continued antibiotic therapy.

CONCLUSION

Hybrid procedure is an alternative approach according to high risk patients with complex anatomy for open repair of infection aortic PSA. The postoperative long-time continued antibiotic therapy must be emphasized for infection PSA.
