对于先前使用牛心包膜(BP)重建下腔静脉(IVC)的患者进行翻修手术的研究很少。据我们所知,医学文献中没有关于重做手术的报道.我们描述了在疾病复发后使用BP进行IVC重建的患者中的两例重做手术。第一例接受了BP移植物的切除,并使用BP进行了第二次IVC重建,第二例患者因广泛的血栓形成而接受了BP移植物的切除而未进行重建.均未出现重做手术后围手术期并发症或发病率,和以前的IVC重建与BP没有显著的术中技术挑战.一个病例显示了切除的BP移植物内皮化的证据,然而,如果第二种情况存在内皮化,则无法明确得出结论.总的来说,这些病例表明,在疾病复发的情况下,既往使用BP重建IVC不应被视为重做手术的绝对禁忌证.
There is a paucity of research investigating revision surgery for patients with previous inferior vena cava (IVC) reconstruction using bovine pericardium (BP). To the best of our knowledge, no
reports of redo procedures have been published in the medical literature. We describe two cases of redo surgery in patients with previous IVC reconstructions using BP following disease recurrence. The first case underwent resection of the BP graft with a second IVC reconstruction using BP, the second
case underwent resection of the BP graft without reconstruction due to extensive thromboses. Neither
case experienced perioperative complication or morbidity following their redo procedure, and previous IVC reconstruction with BP did not present significant intraoperative technical challenges. One
case showed evidence of endothelialisation of the excised BP graft, however, it was not possible to definitively conclude if endothelialisation was present in the second
case. Overall, these cases demonstrate that previous IVC reconstruction using BP should not be considered an absolute contraindication for redo surgery in the context of disease recurrence.
