Abdominal aortic aneurysm in south-west Scotland

Between 1977 and 1988, 155 patients with abdominal aortic aneurysm in the Dumfries and Galloway health region were traced. One hundred and six patients underwent surgery; 57 elective operations for non-leaking aneurysms were performed locally without mortality, and of the 49 patients operated on with ruptured aneurysm, 11 were transferred to a major vascular centre with four deaths (36% mortality rate). The remaining 38 patients were treated locally. Twenty-three of these were operated on by a surgeon with vascular interest with nine deaths (39% mortality rate) and of the remaining 15 patients operated on by a surgeon without a vascular interest, ten died (66% mortality rate). These findings emphasize that patients presenting at a district hospital with leaking abdominal aortic aneurysm should be transferred to a major vascular unit if there is no local vascular expertise available, and our figures suggest that transfer of such patients does not prejudice survival. Further, of those patients who died of leaking aneurysm in hospital without undergoing surgery (25 patients), 15 were in hospital for longer than 3 h without the correct diagnosis. A significant improvement in mortality could follow prompt and accurate diagnosis at hospital level, with the most common error in diagnosis being renal colic.
