Multiple venous collateral pathways have been described in patients with superior vena cava obstruction. Systemic venous-to-pulmonary venous communication is the most unusual, having been described in a few cases of thoracic malignancy. In a patient with fibrosing mediastinitis radionuclide venography with 99Tcm-macroaggregated albumin demonstrated a systemic venous-pulmonary venous right-to-left shunt in addition to systemic and portal venous collaterals. It is apparent that systemic venous-to-pulmonary venous anastomoses may occur in the absence of malignant disease.
上腔静脉阻塞患者已被描述存在多种静脉侧支循环途径。体静脉与肺静脉之间的交通是最不常见的，仅在少数胸部恶性肿瘤病例中有过描述。在一名患有纤维性纵隔炎的患者中，用99Tcm-大颗粒白蛋白进行放射性核素静脉造影显示，除了体静脉和门静脉侧支循环外，还存在体静脉至肺静脉的右向左分流。显然，在没有恶性疾病的情况下也可能发生体静脉至肺静脉的吻合。
