Splenic artery aneurysm

Splenic artery aneurysms are the third most common abdominal aneurysm. The are usually saccular (bulging out one side of the artery) in shape. The majority of splenic artery aneurysms are incidental findings. There is a risk of the aneurysm spontaneously rupturing, particularly with people who undergo a liver transplant, have portal hypertension or are pregnant. If a splenic artery aneurysm ruptures, there is a 1 in 3 mortality rate.
