Objective:To explore the management of particular types of  abdominal aortic aneurysms(AAA).
Methods:The clinical data of 31 patients with particular types of AAA were reviewed retrospectively.
Results:Ruptured abdominal aortic aneurysms (RAAA) were found in 17 cases, mycotic abdomianl aortic aneurysms (MAAA), inflammatory abdominal aortic aneurysms (IAAA) and tuberculous AAA. were found in 3, 4 and 2 cases respectively. The lesions involved the suprarenal artery in 5 cases. One RAAA patient died of shock in emergency room.  Emergency operation was done in 16  patients, elective operation in 14 cases. Replacement of the aneurysm by vascular prosthesis  in 27 cases, and endoluminal treatment in 3 cases. Five cases developed mild postoperative complications. No paralysis or lower extremity arterial embolism occurred in any of the cases. Operative mortality was 6% (2 cases). Twenty-eiggy patients were followed-up for 3 months to 3 years, all of the patients were living well.
Conclusions:Timely surgical therapy for particular types of AAA is important, traditional operation is still effective with improvement of surgical skills, and endoluminal therapy is a new modality gradually applied in the treatment of particular types of AAA.
