TIPS for Platinum-Related Porto-Sinusoidal Vascular Disease With Variceal Bleeding
Sponsor: Air Force Military Medical University, China
Summary
Platinum-based compounds are associated with several adverse effects, including Porto-Sinusoidal Vascular Disease (PSVD). Therapeutic strategies for platinum-related PSVD are based on the management of complications seen in cirrhotic portal hypertension. Currently, a combination of non-selective beta-blockers (NSBB) and endoscopic therapies, such as endoscopic band ligation and endoscopic cyanoacrylate injection, is recommended as the primary approach for the secondary prevention of variceal rebleeding, with Transjugular Intrahepatic Portosystemic Shunt (TIPS) reserved for cases in which first-line treatments fail. However, previous research indicates that endoscopic treatments for the secondary prevention of esophagogastric variceal bleeding show suboptimal efficacy in PSVD patients. In contrast, TIPS has demonstrated comparable rebleeding control but with a lower incidence of liver-related complications and reduced mortality in PSVD patients compared to cirrhotic patients with similar liver function. Based on these findings, the investigators hypothesize that TIPS may be a safer option for this cohort, offering lower rebleeding rates than endoscopic therapy, reduced incidences of hepatic encephalopathy and liver insufficiency, and improved survival rates compared to patients with cirrhosis.

Interventions
Transjugular intrahepatic portosystemic shunt
Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure that uses imaging guidance to connect the portal vein to the hepatic vein in the liver. The TIPS-dedicated stent (Gore, Arizona, USA)was emplaced within the liver and gradually expanded utilizing a balloon with a diameter ranging from 6 to 10 millimeters, aiming for a decrease in portal-venous pressure gradient to less than 12 mmHg or achieve a reduction of 25 to 50% relative to the baseline pressure.
Endoscopic treatment
Endoscopic variceal ligation, endoscopic injection sclerotherapy, endoscopic variceal histoacryl injection therapy , or a combination of several methods were selected according to the location, size, and shape of the patient's varicose veins.Treatment failure can be transferred to TIPS therapy.
