Twenty-five patients with the clinical suspicion of pulmonary thromboembolism underwent venous digital subtraction angiography (DSA) concurrently with selective conventional pulmonary angiography and the results were compared by two independent observers. Our conclusion is that venous DSA lacks adequate specificity and sensitivity for the diagnosis of pulmonary thromboembolism in subsegmental pulmonary arteries. Any benefit derived from this slightly less invasive technique is far outweighed by the decrease in technical detail when compared to the selective film screen method.
25例临床怀疑肺血栓栓塞症的患者同时接受了静脉数字减影血管造影（DSA）和选择性传统肺血管造影，结果由两名独立观察者进行比较。我们的结论是，静脉DSA对于诊断亚段肺动脉内的肺血栓栓塞症缺乏足够的特异性和敏感性。与选择性胶片屏片法相比，这种侵入性稍小的技术所带来的任何益处都远远被技术细节的减少所抵消。
