Side-to-Side Anastomosis

The conditions in which a side-to-side anastomosis is used include the creation of a side-to-side portocaval shunt in portal hypertension, the creation of a side-to-side radiocephalic arteriovenous fistula for chronic hemodialysis, and the creation of a side-to-side arteriovenous fistula distal to an infrainguinal prosthetic bypass as an adjunctive procedure to decrease the outflow resistance. The side-to-side configuration is also used in the construction of the second anastomosis of a sequential bypass when multiple segments of a limb require revascularization.
