OBJECTIVE: To describe the usage and advantages of bovine pericardium mesh (Tutopatch®) in breast reconstruction and to compare different mesh materials used in immediate breast reconstruction.
METHODS: Our study involved a single-center, retrospective analysis of 103 patients (comprising 114 breasts) who underwent immediate implant-based breast reconstruction using bovine pericardium bovine matrix. The procedures were performed by the same surgical team between April 2018 and May 2023.
RESULTS: The rates of early and late complications were examined after a median follow-up period of 30.2 ± 5.5 months. The results revealed that the rates of early complications stood at 9.7%, while late complications were observed in 14.5% of the cases. The most common late complication was seroma formation (7.7%) which six were resolved without any surgical intervention.
CONCLUSIONS: Tutopatch® can be used as an extension of the muscle to cover the prosthesis. It forms an extra layer over the silicone implant that helps to decrease the complications as capsular contracture and implant exposure. It also represents a significant 85 % reduction in cost when compared to a similar-sized mesh materials.

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.

A systematic review was performed for evaluation of the performance of CardioCel® in cardiac surgery. The review included all studies published from January 2013 to December 2020. We conclude that CardioCel is a strong, flexible tissue substitute with good handling characteristics and a low incidence of thrombosis, aneurysm formation, infection, or structural degeneration. It can be used for a variety of intracardiac and extracardiac repairs of congenital heart defects in all age groups with good durability at mid-term follow-up. However, the use of CardioCel in certain positions requires caution. Information on the long-term performance of CardioCel is lacking.

•Bovine pericardium for IVC reconstruction has significant advantages comparing to vascular ligation, autogenous or PTFE grafts.•En-bloc resection of metastatic precaval lymph nodes and reconstruction of the IVC is feasible.•Recurrence of endometrial cancer at para-aortic lymph nodes is good candidate for secondary cytoreduction with MDT approach.
