Acute spontaneous isolated dissection of abdominal aorta

Aortic dissection occurs when the layers of the aorta separate as a result of extra luminal cavity of blood through anintimal tear. dissection limited to the abdominal aorta is rare. unfortunately, the appropriate management of dissecting aneurysm of abdominal aorta is not documented yet. a 43 years old man was admitted to al-zahra hospital in isfahanwith sudden on set of periumbilical abdominal pain. ct scan confirmed infrarenal dissection of abdominal aorta. performing laparotomy, aorta was repaired using bifurcate collagen-coated dacron graft. surgical intervention with syntheticgraft is recommended in patients with dissecting aortic aneurysm of infrarenal segments where the extent of dissectionis limited and accessible.
