Treatment of mycotic aneurysms with involvement of the abdominal aorta: single-centre experience in 44 consecutive cases

Zusammenfassung: | OBJECTIVE: To review our management of mycotic aneurysms involving the abdominal aorta over the past 2 decades to assess the safety and efficacy of in-situ and extra-anatomic repair combined with antibiotic treatment. MATERIALS AND METHODS: From March 1990 to August 2008, 44 patients with a mycotic aneurysm involving the abdominal aorta were treated at our University Hospital. For all patients, we recorded the aetiology, clinical findings and anatomic location of the aneurysm, as well as bacteriology results, surgical and antibiotic therapy and morbidity and mortality. RESULTS: Twenty-one (47.7%) of the mycotic aneurysms had already ruptured at the time of surgery. Free rupture was present in nine patients (20.5%). Contained rupture was observed in 12 patients (27.3%). Urgent surgery was performed in 18 cases (40.9%). Revascularisation was achieved by in-situ reconstruction in 37 patients (84.1%), while extra-anatomic reconstruction was performed in six patients (13.6%). One patient (2.3%) was treated with a combined in-situ and extra-anatomic reconstruction. In one case (2.3%), endovascular aneurysm repair (EVAR) was performed. In-hospital mortality was 22.7%, 50% in the extra-anatomic reconstruction group and 18.9% in the in-situ repair group. One-third (33.3%) of our patients, who presented with a ruptured mycotic aneurysm died in the peri-operative period. This mortality was 13% in the patient-group presenting with an intact aneurysm. Of the 34 surviving patients, 12 patients (27.3% of surviving patients died after discharge from our hospital. In half of these patients, an acute cardiac event was to blame. Three patients (8%) showed re-infection after in-situ reconstruction. CONCLUSION: Management of mycotic aortic aneurysms remains a challenging problem. The results of surgery depend on many factors. In our experience, in-situ repair remains a feasible and safe treatment option for patients who are in good general condition at the time of surgery. |
