Superior vena cava syndrome is a rare complication of pacemaker implantation. Narrowing and occlusion of the superior vena cava is often asymptomatic due to the formation of decompressive collateral pathways to the right atrium. We present a case in which an anomalous venous pathway allowed decompression of the systemic venous return into the left atrium, resulting in arterial desaturation, cyanosis, and fatigue.
上腔静脉综合征是起搏器植入术的一种罕见并发症。由于形成了向右心房的减压侧支通路，上腔静脉狭窄和闭塞通常无症状。我们报告一例患者，其异常静脉通路使体循环静脉回流得以减压进入左心房，导致动脉血氧饱和度降低、发绀和疲劳。
