Minimally invasive surgery (MIS) for redo mitral/tricuspidal surgery is going to increase, offering good results for early and late mortality and morbidity. In a case of redo surgery through a right thoracotomy (RT), when tricuspid surgery is planned, the superior (SVC) and inferior caval veins (IVC) are usually isolated and snared in order to prevent air embolism and significant blood regurgitation. We describe our experience in eight redo patients, operated for combined mitral/tricuspid or isolated tricuspid surgery, where the endovascular occlusion of the SVC and IVC was obtained by means of an endovascular occluder (Equalizer).
微创外科（MIS）在二尖瓣/三尖瓣再次手术中的应用将会增加，为早期和晚期死亡率和发病率提供良好的结果。在右侧开胸（RT）进行再次手术的情况下，当计划进行三尖瓣手术时，通常会隔离并套扎上腔静脉（SVC）和下腔静脉（IVC），以防止空气栓塞和大量血液反流。我们描述了在 8 例再次手术患者中的经验，这些患者因二尖瓣/三尖瓣联合手术或单纯三尖瓣手术而接受手术，其中 SVC 和 IVC 的血管内闭塞是通过血管内封堵器（Equalizer）来实现的。
