The superior vena cava syndrome is among the most important radiotherapeutic emergencies currently known. It is almost always due to malignant disease and therefore no time should be wasted in establishing the histological diagnosis of the malignant tumor which causes the superior vena cava obstruction. The conventional slow, low-dose irradiation is a safe method of treatment. High-dose irradiation in this condition might further compromise the respiratory distress already present thus leading to sudden death.
上腔静脉综合征是目前已知的最重要的放疗急症之一。它几乎总是由恶性疾病引起,因此不应浪费时间来确定导致上腔静脉阻塞的恶性肿瘤的组织学诊断。传统的缓慢、低剂量照射是一种安全的治疗方法。在这种情况下进行高剂量照射可能会进一步加重已有的呼吸窘迫,从而导致猝死。
