New approach to the splenic vessels

Abstract

The transperitoneal approach is used systematically for an arterial or a venous splenorenal anastomosis. However, this approach is associated with high morbidity and mortality rates. Because of our anatomical and surgical findings we have used the retroperitoneal approach to the splenic hilus by means of the lumbar region. The first splenorenal arterial anastomosis with this approach was done in 1972. The approach has proved to be less aggressive since it avoids the danger of damaging the pancreas, it is a more direct approach to the splenic vessels and it provides better exposure and facilitates the anastomosis. In addition, the loss or infection of ascitic fluid in cirrhotic patients is avoided with this approach, as well as intraoperative hemorrhaging caused by the great surplus circulation. There has been neither mortality nor complications in the 13 cases of arterial and venous splenorenal anastomoses that we have done with this method.
