Revision Surgery is Possible in Patients With Previous Bovine Pericardium Inferior Vena Cava Reconstruction: A Case Series and Review of Literature

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.
