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).
The splenorenal ligament is located laterally, the splenocolic ligament inferiorly and the splenophrenic ligament superiorly. followed by suture ligation of the splenic blood supply. After the spleen has been removed, the abdomen is irrigated with normal saline to confirm hemostasis.
Balloon-occluded retrograde transvenous obliteration (BRTO) is an endovascular procedure used for the treatment of gastric varices.When performing the procedure, an interventional radiologist accesses blood vessels using a catheter, inflates a balloon (e.g. balloon occlusion) and injects a substance into the variceal blood vessels that causes blockage of those vessels.
Where clinically appropriate, attempts are now often made to perform either surgical subtotal (partial) splenectomy, [18] or partial splenic embolization. [19] In particular, whilst vaccination and antibiotics provide good protection against the risks of asplenia, this is not always available in poorer countries. [ 20 ]
Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
Warren was a pioneer in surgery for portal hypertension and developed the distal splenorenal shunt. [3] He was the recipient of many honours and served as President of the American College of Surgeons. His memory is honored by an annual lectureship at Emory University.
Portal vein embolization (PVE) is a preoperative procedure performed in interventional radiology to initiate hypertrophy of the anticipated future liver remnant a couple weeks prior to a major liver resection procedure. The procedure involves injecting the right or left portal vein with embolic material to occlude portal blood flow.
