选择性肺血管造影是诊断肺栓塞最好的方法,但需有特殊设备,且不无危险,亦不能探查通常位于下肢深静脉的血栓。作者等采用一种新的造影法,对疑有肺栓塞的病人进行了165次检查。先由下肢静脉作上行腔静脉造影。充盈满意后再由足背静脉注入造影剂,同时将肢静脉压迫,随后将两下肢抬高45°。去除压迫时,拍摄一系列胸片(译者按:透视定位摄片),右心腔和肺血管可得到良好充盈。和25例选择性肺血管造影相比,作者等认为该检查法的意义颇大:①X线设备较简单,操作方法简易,仅需作静脉穿刺,②病人能较好忍受,③对诊断颇有价值,仅在7%病例中诊断困难,尤其当栓子极
Selective pulmonary angiography is the best method of diagnosing pulmonary embolism, but requires special equipment and is not risk-free. Nor can it detect thrombi that are usually found in deep veins of the lower extremities. The authors used a new angiography method to examine 165 patients suspected of having pulmonary embolism. First by the lower extremity venous vein for angiography. Filled with satisfactory dorsal venous injection of contrast agent, while the venous oppression, followed by two lower limb elevation 45 °. To remove the oppression, a series of chest radiographs were taken and the right heart cavity and pulmonary vessels were well filled. Compared with 25 cases of selective pulmonary angiography, the authors believe that the significance of the test is quite large: ① X-ray device is relatively simple, simple operation method, only for venipuncture, ② patients can endure better, ③ diagnosis quite Value, diagnostic difficulty only in 7% of cases, especially when the embolic pole
