目得：回顾性评估的计算机断层扫描（CT）功能的肺动脉残端血栓形成在初始和后续CT.MATERIALS和METHODS：该研究是由机构审查委员会批准，放弃知情同意书，并符合HIPPA。所有患者接受了肺切除术和CT从2001年1月至2003年8月，通过数据检索系统确定，包括在内。研究了89例患者（49例男性，40例女性;平均年龄60岁）。血栓识别、分类（凹面或凸面）以及残端和血栓测量由两名放射科医生一致进行。抗凝治疗的使用根据患者病历确定。结果：肺切除术后34个月，67个月（标准差）获得首次CT扫描，58例患者在手术期间获得多次CT扫描。随访25.1个月± 24.8个月。89例患者中有11例（12.4%）有残端血栓，两侧的频率几乎相等。最初识别出5个凹状血栓和6个凸状血栓。未开始抗凝治疗残端血栓形成。右侧残端平均长度（31 mm 10）大于左侧残端（13 mm 7）（P
PURPOSE: To retrospectively evaluate the computed tomographic (CT) features of pulmonary artery stump thrombosis at initial and follow-up CT.MATERIALS AND METHODS: The study was approved by institutional review board, which waived informed consent, and was, HIPPA compliant. All patients who had undergone pneumonectomy and CT from January 2001 to August 2003, as identified with data search system, were included. Eighty-nine patients (49 men, 40 women; mean age, 60 years) were studied. Thrombus identification, categorization (concave or convex), and stump and thrombus measurements were made by two radiologists in consensus. The use of anticoagulation therapy was determined from patients' charts. The t test was used.RESULTS: Initial CT scans were obtained 34,months, 67 (standard, deviation) after pneumonectomy; multiple CT scans were obtained in 58 patients during. follow-up of 25.1 months +/- 24.8. Eleven (12.4%),of 89 patients had stump thrombi with near equal frequency on either side. Five concave and six convex thrombi were 1 initially identified. Anticoagulation was not commenced for stump, thrombosis. The mean length of the right stump (31 mm 10) was greater than that of the left stump (13 mm 7) (P
