Results of Experiments on Replacement of superior Vana Cava

Abstract

Replacement of Superior Vena Cava was experimented in 26 dogs with autogeneous venous graft, homologus artery graft, Edward Tape nylon graft, Edward Tape nylon graft with arterio venous fistula and Edward Tape nylon graft with anticoagulants. The results arc discussed in detail and problems of venous grafts which are mainly due to the slow blood flow and blood clotting in grafts, arc explained. Arteria venous fistula between right carotid artery and right jugular vein eliminate Using anticoagulants has been done in only two cases and this is not draw a conclusion. However, it seems that this would be rather dangerous because of slow blood flow in superior vena cava and the risk of bleedingdanger of blood clotting but has the danger of right heartfailur.
