  • Title: Technical aspects in the management of abdominal aortic aneurysms.
    Author: Sheiner NM.
    Journal: Can J Surg; 1983 Nov; 26(6):523-8. PubMed ID: 6627144.
    Abstract:
    During the past decade, resection of abdominal aortic aneurysms has become common. The technical aspects of the operation are now relatively standardized and simplified. With concomitant improvements in anesthesia and intensive care, the operative mortality for elective resection of these aneurysms has declined progressively; several centres report an operative mortality of less than 5%. The author considers the following principles important in managing patients with abdominal aortic aneurysms: (a) simplicity and limited dissection are critical features of the operative technique; (b) tubular grafts should be used whenever possible; (c) selected patients should be transferred to the intensive care unit preoperatively for "fine-tuning" of the cardiovascular system; (d) patients should be monitored intraoperatively and postoperatively; (e) the surgeon should be aware of special problems such as horseshoe kidney, venous anomalies, adherent duodenum and the presence of major arteries arising from the aneurysm; (f) ruptured aneurysms should be diagnosed promptly and the patient operated upon without delay. Using these principles, the author's group achieved an operative mortality of only 1.8% in 168 patients with abdominal aortic aneurysms resected electively. However, the operative mortality for their patients with ruptured aortic aneurysms was 50%, a rate that has not changed appreciably over the years.
