PURPOSE
To evaluate the role of computed tomography (CT) in diagnosis of chronic thromboembolic pulmonary hypertension, assessment of surgical operability, and follow-up after surgery.
MATERIALS AND METHODS
Seventy-five patients with chronic thromboembolism were examined with CT; 63 underwent thromboendarterectomy, and postoperative CT scans were acquired in 23. CT scans were analyzed for vascular and parenchymal changes, and findings were compared with those on lung scintigrams and with surgical results.
RESULTS
CT findings allowed confirmation of the diagnosis of chronic thromboembolism and ensured technical operability (sensitivity, 77%; specificity, 100%; overall accuracy, 80%) by means of direct visualization of thrombi in central pulmonary arteries in 53 patients.
CONCLUSION
CT enables demonstration of pulmonary thromboembolism with criteria pertaining to pulmonary arteries and to lung parenchyma and enables assessment of technical operatibility and confirmation of surgical success.
目的
评估计算机断层扫描（CT）在慢性血栓栓塞性肺动脉高压诊断、手术可操作性评估及术后随访中的作用。
材料与方法
对75例慢性血栓栓塞患者进行CT检查；63例行血栓内膜剥脱术，其中23例术后接受了CT扫描。分析CT扫描的血管和实质改变，并将结果与肺闪烁扫描结果及手术结果进行比较。
结果
CT表现可确诊慢性血栓栓塞，并通过直接观察53例患者中央肺动脉内的血栓确定技术可操作性（敏感性77%；特异性100%；总体准确性80%）。
结论
CT能够依据肺动脉和肺实质标准显示肺血栓栓塞，能够评估技术可操作性并证实手术成功。
