The port access site is fixed at 5 cm below the midline of the clavicle and 9 to 10 cm lateral to the midline of the chest. Then, a 5 to 6 cm incision is made to create a subcutaneous tissue pouch for the placement of port access site. A tunnel is made from the port access site until adjacent to the internal jugular neck wound.
A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.
In medicine, vascular access is a means of accessing the bloodstream through the peripheral or central blood vessels in order to obtain blood or deliver medications including chemotherapy. A vascular access procedure involves insertion of a sterile plastic tube called a catheter into a blood vessel. Types of catheters can be either peripherally ...

Most common complications with venous access are catheter related infections, thrombophlebitis and venous thrombosis. If having thrombophlebitis or thrombosis; pain when using the access is another complication. Peripheral venous access is least prone to thrombosis, followed by midline catheters and the centrally placed catheters.
In medicine, a distal splenorenal shunt procedure (DSRS), also splenorenal shunt procedure and Warren shunt, [1] is a surgical procedure in which the distal splenic vein (a part of the portal venous system) is attached to the left renal vein (a part of the systemic venous system).
