Abstract
We report a case of a mycotic abdominal aortic aneurysm caused by invasive group B streptococcus. Given the anatomical suitability with healthy segments of aortoiliac vessels, in situ repair was performed. A cryopreserved femoral vein graft was chosen because of risks of graft reinfection and negated the need for bilateral femoral vein harvest. The patient remained clinically well and the graft patent with no concerns at 6 months of follow-up. A review of literature on group B Streptococcus aortitis was performed.
Highlights
Mycotic aneurysms account for less than 2% of surgically repaired aortic aneurysms but are associated with marked morbidity and a mortality rate of 15%-50%.1-3 The management of mycotic abdominal aortic aneurysms (AAAs) includes antibiotics and timely surgical repair
We report a case of infectious aortitis caused by Group B Streptococcus (GBS) and repaired with a cryopreserved
All other laboratory workups were otherwise unremarkable. She had an abdominal/pelvis computed tomography (CT) scan that showed nonspecific fat stranding around a mildly dilated aorta maximally measuring 3.0 Â 2.7 cm (Fig). She was empirically treated with piperacillin/tazobactam for presumed diverticulitis
Summary
D, 3D reconstruction of the CTA displaying the enlarging aneurysm. Infectious diseases was consulted, and the patient was switched to ceftriaxone for 6 weeks, followed by oral amoxicillin for a year thereafter. The patient was discharged 10 days postoperatively. At 6 months of follow-up, she remained clinically well and CT imaging demonstrated resolution of surrounding stranding without any signs of pseudoaneurysm or deformities
