ABSTRACT
Infectious abdominal aortic aneurysm is a relatively rare disease, and there is no consensus regarding its surgical treatment. Medical infectious control should be concerned comparison with surgical treatment if there is sepsis, however we sometimes have no other choice but emergency operation for uncontrollable cases. In many reports, cryopreserved homografts were used as <i>in</i>-<i>situ </i>alternative grafts for infectious aortic aneurysms because they had some merits such as anti-infectious effects, suitability and so on. However the number of <i>in-situ </i>cryopreserved homograft replacement cases are few, and the long term result is unclear. We encountered a ruptured cropreserved homograft case 7 months after urgent <i>in-situ </i>cryopreserved homograft replacement. We report the case and refer to the relevans literature.
