作者利用切除肺标本作血管造影,证实孤立性肺内小肿块内、边缘及其周围血管征象的病理基础。29例孤立性肺肿块的直径为1.5～3.5cm。在病灶切除前1～3天,全部病例摄有胸片、普通体层,部分病例作了CT扫描。为了观察病灶的动脉征象,将钡胶浆缓慢灌注入24例肺叶切除标本的动脉内,直至胸膜表面的动脉终末支充盈。5例肺癌体层片可见肿块远侧有扩张的血管带。为证实这些血管带是否为阻塞的静脉,作者用上述方法作标本静脉造影。然后, The authors used excisional lung specimens as angiograms to demonstrate the pathological basis for the signs of blood vessels in, around, and around small lumps in isolated lungs. 29 cases of solitary lung lump diameter of 1.5 ~ 3.5cm. 1 ~ 3 days before the lesion was excised, all cases were taken chest radiographs, common body layers, CT scan was performed in some cases. In order to observe the lesion’s arterial sign, barium cement was slowly infused into the artery of 24 lobectomy specimens until the terminal branch of the artery on the pleural surface was filled. In 5 cases of lung cancer, there was a dilated vascular zone distal to the tumor. To confirm whether these vascular bands are obstructed veins, the authors used the above method for venous angiography. then,
