对69例胃肠出血病人作了血管造影,11例静脉曲张的病人及1例失去随访者排除出研究组。其余57例(男28例,女29例)共有60人次血管造影象用于分析,年龄多数在60～80岁(4.3～84.7岁),平均59.4岁。这些病人又分为两组,①组包括48例,为已证实有大量出血、至少有一次引起突然入院的明显胃肠失血发作者。②组包括了其余9例有慢性缺铁性贫血史的病人,认为贫血是由于隐性胃肠失血引起。这些病人的血管造影结果是:①组17例正常,10例显示有活动性出血。19例为血管结
Angiography was performed on 69 patients with gastrointestinal bleeding, 11 patients with varicose veins, and 1 patient who lost their follow-up were excluded from the study. The remaining 57 patients (28 males and 29 females) had a total of 60 angiographic images for analysis. The majority were 60 to 80 years old (4.3 to 84.7 years) with an average of 59.4 years old. These patients were further divided into two groups, ① the group consisted of 48 patients who were confirmed to have significant bleeding and had at least one apparent gastrointestinal bleeding who had suddenly admitted to the hospital. ② The group included the remaining 9 patients with a history of chronic iron-deficiency anemia, suggesting that anemia was caused by occult gastrointestinal hemorrhage.
