Objective:
To evaluate the efficacy of the renal capsule for reconstruction of the inferior vena cava in a canine model.
Materials And Methods:
The present study was conducted on 10 dogs; an oval window (2-8 cm long, mean 6.5 cm) was made in the inferior vena cava and then repaired using the autologous renal capsule patch. The patency and functionality of the graft were assessed macroscopically and microscopically 3 months postoperatively.
Results:
All the dogs were killed at 3 months, showing excellent patency of the vena cava macroscopically and in the venography. In the microscopic examination, all the patches were completely endothelialized. No evidence of infection or thrombosis was noted.
Conclusion:
A renal capsule patch can be used for reconstruction of the inferior vena cava. Patency appears to be good, and the risk of infection is low. Moreover, this is an accessible material.
