【摘要】：【目的】回顾性分析消化道恶性肿瘤住院患者行常规MDCT(Multi-Detector computed tomography)扫描时意外检出肺动脉栓塞(UPE)的检出率、基本人口资料特征以及首次诊断时影响检出率的因素。【方法】搜集确诊消化道恶性肿瘤且行常规胸部增强检查的住院患者1 974例,回顾性分析其CT表现及临床资料,统计发生肺栓塞(PE)的患者,计算患者栓塞指数,记录栓塞部位、栓塞范围。发生PE的患者根据是否有症状分为有症状(14例)及无症状组(44例),根据首次诊断结果分为真阳性组(27例)和假阴性组(31例)。【结果】58例消化道恶性肿瘤住院病人并发UPE。UPE检出率为2.94%,平均年龄(62.2±1.4)岁,各类肿瘤检出率顺序为肛管癌(25%)、胰腺(6.12%)、胃(4.11%)、小肠(2.78%)、大肠(2.59%)、食管(0.96%),病理组织学类型以腺癌为主(86.21%)。有症状PE患者多为中央型及双侧的肺栓塞。首次诊断真阳性率为46.55%(27例),有症状、严重型、中央型及双侧肺动脉栓塞更容易在首次诊断中检出。【结论】临床症状、肺动脉栓塞指数、栓塞部位、栓塞范围等因素影响UPE的检出率。
[Abstract]:[objective] to analyze retrospectively the detection rate of pulmonary embolism (UPE) in patients with gastrointestinal malignancy by routine MDCT(Multi-Detector computed tomographyscan. [methods] the CT findings and clinical data of 1 974 inpatients who were diagnosed as malignant tumors of digestive tract and underwent conventional chest enhancement examination were retrospectively analyzed. The patients with PE) were counted, the embolism index was calculated, and the embolism site was recorded. The patients with PE were divided into symptomatic group (n = 14), asymptomatic group (n = 44), true positive group (n = 27) and false negative group (n = 31). The detection rate of UPE.UPE in inpatients was 2.94 and the average age was 62.2 卤1.4 years old. The detection rates of various kinds of tumors were: anal canal carcinoma 25, pancreas 6.12, stomach 4.11, small intestine 2.78, large intestine 2.59, esophagus 0.96, histopathology 86.21. Symptomatic PE patients were mainly central type and bilateral pulmonary embolism. The true positive rate of the first diagnosis was 46.55%. Severe type, central type and bilateral pulmonary embolism were more easily detected in the first diagnosis. [conclusion] Clinical symptoms, pulmonary embolism index, embolism site, embolism extent and other factors affect the detection rate of UPE.
