The purpose of this study is to investigate the incidence of aneurysmal subarachnoid hemorrhage (SAH) in Youngdong district for 10 years.
From Jan. 1997 to Dec. 2006, 732 patients (327 males, 405 females, mean age: 54.8+/-13.1 years) with spontaneous SAH were admitted to our hospital. We reviewed the medical records and radiological findings regarding to the ictus of SAH, location and size of the ruptured aneurysms, Hunt-Hess grade and Fisher grade on admission, personal details such as address, age, and sex, and previous history of medical diseases.
In these 732 patients, 672 cases were confirmed as aneurysmal SAH. Among them, 611 patients (262 males, 349 females, mean age: 54.9+/-13.2 years) came from Youngdong district. The average crude annual incidence of aneurysmal SAH for men, women, and both sexes combined in Youngdong district was 7.8+/-1.7, 10.5+/-2.7, and 9.1+/-2.1 per 100,000 population, respectively. Because of the problems related to the observation period and geographical confinement, it was suspected that the representative incidence of aneurysmal SAH in Youngdong district should be made during the later eight years in six coastal regions. Therefore, the average age-adjusted annual incidence for men, women, and both sexes combined was 8.8+/-1.4, 11.2+/-1.3 and 10.0+/-1.0, respectively in the coastal regions of Youngdong district from 1999 to 2006.
In overall, our results on the incidence of aneurysmal SAH was not very different from previous observations from other studies.
本研究旨在调查10年间岭南地区动脉瘤性蛛网膜下腔出血（SAH）的发病率。
1997年1月至2006年12月，732例自发性SAH患者（男性327例，女性405例，平均年龄：54.8±13.1岁）入住我院。我们回顾了有关SAH发作、破裂动脉瘤的位置和大小、入院时的Hunt-Hess分级和Fisher分级的病历及影像学检查结果，以及诸如地址、年龄和性别等个人信息，还有既往病史。
在这732例患者中，672例被确诊为动脉瘤性SAH。其中，611例患者（男性262例，女性349例，平均年龄：54.9±13.2岁）来自岭南地区。岭南地区男性、女性及两性合并的动脉瘤性SAH平均粗年发病率分别为每10万人7.8±1.7、10.5±2.7和9.1±2.1。由于观察期和地域限制问题，怀疑岭南地区动脉瘤性SAH具有代表性的发病率应在六个沿海地区的后八年统计得出。因此，1999年至2006年岭南地区沿海地区男性、女性及两性合并的年龄调整年发病率分别为8.8±1.4、11.2±1.3和10.0±1.0。
总体而言，我们关于动脉瘤性SAH发病率的结果与之前其他研究的观察结果差异不大。
