Six-year progression of medically treated infective aortitis.

ObjectiveTo report a medically treated case of infective aortitis with mycotic aneurysms that went on to have many years of surveillance imaging. This has not yet been documented as current recommendations for infective aortitis strongly suggest operative intervention combined with aggressive antibiotics, with very high reported mortality for non-operative management. Thus, the natural progression of sac growth during the acute infective period and in the long-term has had an opportunity to be explored.MethodsA 77-year-old patient presented with infective aortitis confirmed on computed tomography angiography and refused operative intervention despite being explained the associated risks and benefits. She was treated aggressively with antibiotics and monitored in the community, successfully clearing the infection.ResultsShe received a total of 6 weeks of ceftriaxone intravenously and 1 year of oral ciprofloxacin. She rapidly developed mycotic aneurysmal disease both infrarenal and suprarenal which stabilised within 1 year after diagnosis and did not progress further.ConclusionsInfective aortitis with mycotic aneurysms is usually treated surgically due to the significant risk of rupture in the acute period. This case suggests that if the acute infective period is passed, the aneurysmal disease stabilises and does not progress.
