Cryopreserved venous allograft in the treatment of a mycotic abdominal aortic aneurysm caused by group B Streptococcus

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.

Suspected Mycotic Aneurysm of the Aortic Arch in the Setting of Group B Strep Bacteremia

“…We now know that most mycotic aneurysms are precipitated by bacterial infections with Staph aureus being the most common in Western Countries [1]. Group B strep mycotic aneurysms are exceedingly rare with very few published case reports [2][3][4][5][6][7][8][9][10][11][12]. We report a case of mycotic aortic aneurysm suspected to be caused by GBS bacteremia in a 60-year-old male.…”

“…Treatment is either with intravenous antibiotics, surgical repair, or a combination of both [1,14]. GBS associated mycotic aneurysm was first described in 1989 by Blackett, et al However, since that time GBS in the grand scheme of mycotic aneurysms has been found to be a much less common organism accounting for very few cases [2][3][4][5][6][7][8][9][10][11][12].…”

Infectious Aortitis: Case Report and Literature Review

“…The patient was diagnosed with abdominal aortitis with the formation of a saccular aneurysm formation within a couple of days. Few cases of aortitis with aneurysmal formation with variable patient presentations have been reported in the literature [ 4 - 10 ]. We aim to highlight the different etiologies, diagnostic tools, and management approaches for aortitis to emphasize the importance of early detection and proper management of aortitis.…”
