Superior vena cava (SVC) syndrome results from the blockage of venous blood flow through the SVC, which is caused by either internal obstruction (eg, thrombus) or external compression (eg, thoracic malignancy and infection).1 While thrombus-related SVC syndrome is rising in prevalence, malignancy still accounts for the majority of cases.1 Regardless of cause, SVC syndrome is characterised by facial swelling and plethora, headache and dyspnoea.2 Although venous stenting has become standard of care for treatment of acute SVC syndrome, stent placement presents multiple risks including SVC rupture and cardiac tamponade. In these cases, a high index of suspicion and prompt action are required to avoid an often fatal outcome. Here, we present the case of a patient with cardiac tamponade and subsequent cardiac arrest after SVC stent placement.
上腔静脉（SVC）综合征是由于 SVC 内的血流阻塞引起的，阻塞原因可能是内部阻塞（例如血栓）或外部压迫（例如胸部恶性肿瘤和感染）。1 尽管与血栓相关的 SVC 综合征的患病率正在上升，但恶性肿瘤仍然占大多数病例。1 无论病因如何，SVC 综合征的特征是面部肿胀和充血、头痛和呼吸困难。2 尽管静脉支架置入术已成为急性 SVC 综合征的标准治疗方法，但支架置入术存在多种风险，包括 SVC 破裂和心脏压塞。在这些情况下，需要高度怀疑并迅速采取行动，以避免经常致命的后果。在这里，我们介绍了一例 SVC 支架置入术后发生心脏压塞和随后心脏骤停的患者。
