Abstract    Ruptured abdominal aortic aneurysm (rAAA) is one of the major leading causes of sudden death in the world. Despite many advances in the field of vascular surgery, the improvement in prognosis of rAAA has been very modest. Although endovascular treatment of rAAA is associated with decreased morbidity and mortality markedly when compared to the open surgical approach, open rAAA repair remains the most common therapy for the devastating vascular emergency. It will focus on diagnosis and management for rAAA in either open or endovascular aneurysm repair with particular attention to developing a standardized multidisciplinary approach to deal with the technical challenges, including the availability of preoperative CT, the choice of anesthesia, use of aortic occlusion balloons, need for bifurcated vs. aorto-uniiliac stentgrafts, diagnosis and treatment of abdominal compartment syndrome, and endovascular treatment conversion to open surgical repair. The open and endovascular repairs play equally important roles in management of rAAA.
