While this approach does eliminate the possibility of rupture in these patients, a considerable contingent of individuals, with small aneurysms, would be subjected to major surgical operations, which are never risk free and may be unnecessary, since many aneurysms remain stable 9 9. The advantage of early operation for abdominal aortic aneurysm. The cost-effectiveness of early surgery versus watchful waiting in the management of small abdominal aortic aneurysms.
This finding led to an aggressive approach to treatment of aneurysms, with surgery prescribed even for low risk patients, the elderly and patients with aneurysms considered to be small. Recommended indications for operative treatment of abdominal aortic aneurysms: report of a subcommittee of the Joint Council Of the Society for Vascular Surgery and the North American Chapter of the International Society for Cardiovascular Surgery J. mortality from ruptured aneurysms remained elevated (over 50%). Avaliação da mortalidade cirúrgica em aneurismas infra-renais da aorta abdominal. In: Bonamigo TP, Burihan E, Cinelli M Jr, Ristow A. Tratamento de urgência nos aneurismas da aorta abdominal. Tratamento cirúrgico eletivo do aneurisma da aorta abdominal. Bechara MJ, Langer B, Malavolta LC, Kusniec S, Andrade MFC, Presti C, et al. Surgical management of abdominal aortic aneurysms: factors influencing mortality and morbity: 20 year experience. Thompson JE, Hollier LH, Patman RD, Persson AV. An understanding of the natural history of the disease became indispensable and many studies were conducted to investigate this subject.Īs the number of patients operated increased, it became clear that, although mortality rates linked to elective conventional surgery exhibited a reduction over the years (17.4% to 5.0% in 20 years, 2 2. The prospect of effective treatment began to raise doubts with relation to which patients with asymptomatic aneurysms were suitable candidates for treatment. Development of arterial substitutes, more rigorous surgical techniques, better understanding of the disease, and the advent of ultrasonography which increased diagnoses and perfected preoperative, intraoperative (anesthesia) and postoperative clinical control, surgery for infrarenal aneurysms came to be routine and results became ever more encouraging. īegan the era of effective repair of aneurysms of the infrarenal aorta using homologous cadaveric aorta grafts, after aneurysmectomy. Resection of aneurysm of the abdominal aorta: reestablishment of the continuity by preserved human arterial graft, with result after 5 months.
