Abstract

Title: Pasteurella Multiocida Infection Resulting in a Descending Thoracic Aorta Mycotic Pseudoaneurysm Objective: Highlight our management of a P. Multiocida infected descending thoracic aorta mycotic pseudoaneurysm Methods: Report a case of canine bite resulting in a P. Multiocida descending thoracic aorta mycotic pseudoaneurysm Results: We present a 61-year-old gentleman who was initially seen in an Emergency Department after a canine bite. He was admitted and treated with a course of IV antibiotics for P. Multiocida bacteremia and discharged. Three weeks post discharge, he continued to feel generalized malaise and work-up was significant for a descending thoracic aorta mycotic pseudoaneurysm. The patient underwent a low left posterior lateral thoracotomy and femoral-femoral cardiopulmonary bypass for complete resection and replacement with a 24 mm GelweaveTM graft (Terumo Cardiovascular Group, Ann Arbor, Michigan). Given purulence and gross infection we planned for a staged approach, with a secondary washout and omental flap for biologic coverage of the graft. The patient did well clinically and was discharged at 14 days to rehabilitation with six-week intravenous course of antibiotics. Conclusions: The patient’s clinical course with subsequent follow-up suggest that complete resection of the mycotic pseudoaneurysm, followed by omental flap coverage is a viable strategy to manage mycotic aortic infections with virulent organisms.
