Abdominal aortic aneurysms.

The dangers of any abdominal aortic aneurysm are discussed, and the disastrous combination of an aneurysm and abdominal pain emphasised. These anerysms can be divided into 4 groups. The presentation and operative mortality for each group is discussed, as is the long term survival, state of the peripheral circulation and general health after operation. How results can be improved is considered. It is concluded that all such aneyrysms should be operated upon because of the good immediate and long term results in comparison with those not operated upon.
