Abstract:Objective:To explore the diagnosis and management of ruptured abdominal aortic aneurysm (RAAA).
Methods:Twelve patients with RAAA treated in past 7 years were revienled retrospectively. The main clinical manifestations were abdominal pain and / or back pain， low blood pressure or shock，and pulsating abdominal mass. All cases were accurately diagnosed with CT and 7 were treated by conventional operation, one by EVAR, and the other 4 did not receive surgical treatment.
Results:Perioperative death occurred in 5 cases (mortality rate was 62.5%) in 8 surgical treated patients, including circulatory failure in 2 cases, renal failure in 1 case, and multiple organ failure in 2 cases. All the 4 patients treated with nonoperative method were dead.
Conclusions:Surgical operation in RAAA cases still carried a high mortality.Early dignosis, appropriate resuscitation， urgent surgical repair, reduction of operative time, and infrarenal clamping are measures conducive to lowering the mortality rate of RAAA. EVAR has the potential to reduce the mortality rate from RAAA.
