There is an increase in the incidence of abdominal aortic aneurysm (AAA) over the last six decades, probably as a result of higher longevity and lifestyle changes witnessed in the years following World War II. Though earlier studies mainly from Southern Africa suggest abdominal aortic aneurysms as uncommon amongst black Africans, recent reports from Africa emphasized an increasing incidence of vascular diseases and its sequelae including AAA. There are, however, few documented case reports of AAA in our environment over the years suggesting the rarity of this disease. We report the management and outcome of three different types of infrarenal AAA with synthetic graft in a General Surgery Unit over a four-year period between 2001 and 2005. Follow-up evaluation confirmed a successful outcome in two patients. Abdominal aortic aneurysms may be occurring more frequently than reported in our environment and its management, using basic evaluation techniques, can be successfully achieved with reasonable outcome when performed in a non-specialized unit by General Surgeons in institutions with limited resources. Contrary to the popularly held view of rarity of AAA, the disease may be increasing in incidence amongst black African. Its evaluation and treatment is also feasible with the availability of reconstructive graft in a non-specialized surgical unit.
在过去的六十年里，腹主动脉瘤（AAA）的发病率有所上升，这可能是由于二战后人们寿命延长以及生活方式改变所致。尽管早期主要来自非洲南部的研究表明，腹主动脉瘤在非洲黑人中并不常见，但近期来自非洲的报告强调，包括AAA在内的血管疾病及其后遗症的发病率正在上升。然而，多年来在我们所处的环境中，记录在案的AAA病例报告很少，这表明这种疾病很罕见。我们报告了2001年至2005年的四年间，在一个普通外科病房对三例不同类型的肾下腹主动脉瘤进行人工血管移植的治疗及结果。随访评估证实两名患者治疗成功。腹主动脉瘤在我们所处环境中的实际发生频率可能比报告的要高，并且在资源有限的机构中，由普通外科医生在非专科病房采用基本评估技术对其进行治疗，也能成功实现并取得合理的治疗效果。与普遍认为腹主动脉瘤罕见的观点相反，这种疾病在非洲黑人中的发病率可能正在上升。在非专科手术病房有重建血管可用的情况下，对其进行评估和治疗也是可行的。
