在慢性硬膜下血肿病例中,头指数(cephalic ind-ex)小者即长头者(dolichocephaly)较为多见,本文就头指数与发生慢性硬膜下血肿的关系进行探讨。1.对象与方法自1983～1987年多月共收治慢性硬膜下血肿62例(男51例,女11例),同时随机抽样因头部外伤来院就诊,经观察未发生颅内血肿的40岁以上患者62例(男51例、女11例)作为对照组。共124例用单纯头部拍片测定头指数(头指数=宽度×100/长度)。宽度取正位像的最大径,长度取侧位像的最大径。慢性硬膜下血肿组平均年龄67.3岁,对照组为65.1岁。慢性硬膜下血肿组62例中,有11例无明显外伤史,但既往亦无开颅手术、分流术、出血疾病或抗凝治疗以及合并其他颅内疾病史,考虑仍为外伤原因所致,而归为一组。2.结果慢性硬膜下血肿组的头指数平均值:男79.0,女81.3。对照组男82.1,女83.3。前者的男女平均值都小于后者。头指数<75的长头者所占比例是:慢性硬膜下血肿组男性51例中有8例(占15.7%)
In the case of chronic subdural hematoma, dolichocephaly is more common in patients with small head index (cephalic ind-ex), this paper discusses the relationship between head index and occurrence of chronic subdural hematoma. 1. Subjects and Methods From 1983 to 1987 months were treated a total of 62 cases of chronic subdural hematoma (51 males and 11 females), at the same time random sampling of head trauma to the hospital, the observation of intracranial hematoma did not occur 40 62 patients aged over (male 51, female 11) as a control group. A total of 124 patients with a simple head film measured head index (head index = width × 100 / length). The width takes the maximum diameter of the positive image and the length takes the maximum diameter of the image of the horizontal image. Chronic subdural hematoma group average age of 67.3 years, 65.1 years in the control group. Chronic subdural hematoma 62 cases, 62 cases, no obvious history of trauma, but no previous craniotomy, shunt, bleeding or anticoagulant therapy and other intracranial disease history, consider the reasons for the trauma is still caused , And grouped together. 2. Results Chronic subdural hematoma group head index average: male 79.0, female 81.3. Control group male 82.1, female 83.3. The former is less than the latter on average. The proportion of long-headed persons with a head index <75 was: 8 of 51 (15.7%) of the 51 patients with chronic subdural hematoma
