In situ polytetrafluorethylene graft bypass for contained rupture of rapidly progressing aortic pseudoaneurysm due to severe infectious aortitis.

Infectious aortitis is a rare disease with an unfavorable prognosis, although prompt and adequate treatment can reduce its high mortality rate. Pseudoaneurysms caused by aortitis tend to rupture when treatment is delayed. For this reason, determining the appropriate timing of surgical repair is critical. To date, there are no data regarding the expansion rate of the aortic wall after an aortic infection. We report a case of successful surgical treatment of rapidly progressing aortic expansion that resulted from severe infectious aortitis using in situ reconstruction. No complications were experienced by this patient over the 4-year follow-up period.
