Tuberculous aortitis

ABSTRACT

Tuberculous aortitis [TA] is a rare entity that is invariably indicative of disseminated tuberculosis. TA is associated with aneurysm formation in about half of cases. Another possible complication is perforation of adjacent structures [1-7]. Both abdominal and thoracic aorta are involved with equal frequency.[7-9] Fatal outcomes are frequently reported even after antituberculosis chemotherapy and surgical intervention. We present a case of tuberculous aortic aneurysm [TBAA] that underwent surgical resection and graft replacement in the bed of the infected aorta. Following an apparently successful chemotherapy, the patient died suddenly. We postulate that reactivation of the un-eradicated bacilli precipitated graft failure. Similar cases in the literature are reviewed. We propose lifelong suppressive therapy with antituberculosis agents to prevent such a catastrophic event
