Is the use of biological grafts for reconstruction of the inferior vena cava a safe and valid alternative : results in 32 patients in a single institution?
The preferential use of synthetic grafts in IVC replacement is not evidence based. Selection of an appropriate prosthetic graft for IVC reconstruction should be based on the safety and its handling features. The use of biological grafts for IVC repair is a valid alternative to current synthetic materials and may in fact be superior in terms of biocompatability, ease of handling, reduced rate of infection and improved long-term patency without permanent anticoagulation.
There is diurnal fluctuation in endothelial function, which is associated with variation in the frequency of ischemic episodes.
