Abstract
OBJECTIVE
This study aims to analyze the early and late outcomes of our 30-year experience with mycotic aneurysms of the abdominal aorta and iliac arteries.
PATIENTS AND METHODS
This retrospective cohort study compared the outcomes of all the patients with mycotic aneurysm, by analyzing prospectively collected data between September 1989 and October 2019 from the Unit of Vascular Surgery of Fondazione Policlinico Universitario Gemelli - IRCCS in Rome, Italy.
RESULTS
Twenty-three patients with mycotic aneurysm were included. Twenty-two patients underwent surgery; one patient arrived at the emergency room with unstable clinical conditions and died before being treated. Fourteen cases (60.9%) were located at the infrarenal aorta, while three cases (13.0%) were pararenal aortic aneurysms. Six cases (26.1%) had an iliac arteries localization. Seventeen patients (77.3%) underwent open surgical repair aneurysmectomy with in situ reconstruction, while three cases (13.6%) underwent extra-anatomic revascularization. Three patients (13.6%) underwent the placement of an endoprosthesis, of whom two underwent hybrid procedures, and one EVAR. The latter underwent an early conversion to open repair due to a type I endoleak. The mean length of hospital stay was 35 ± 18.7 days. Five patients (22.7%) died in the immediate postoperative period. In the follow-up of 45.5 ± 41.3 months (range 2-156), we documented six deaths (35.3%), of whom two (11.8%) were aortic-related for a 34.8% overall aortic-related mortality. Eleven patients were alive, with an overall survival of 47.8%.
CONCLUSIONS
Mycotic aneurysm is an extremely rare and varied pathology. Open surgical repair showed to be a safe approach because of a complete and aggressive debridement of local infected tissues, with an acceptable long-term mortality rate.
