Mesocaval "H" graft using antogenous vein graft

Area of Science:

• Vascular Surgery
• Gastroenterology
• Hepatology

Background:

• Esophageal varices pose a significant bleeding risk in patients with portal hypertension.
• Mesocaval shunts are a surgical option to decompress the portal venous system.
• Autogenous vein grafts offer a readily available and biocompatible material for shunt creation.

Purpose of the Study:

• To evaluate the efficacy and safety of mesocaval "H" shunts using autogenous veins for treating bleeding esophageal varices.
• To assess the long-term patency and complication rates associated with this surgical technique.

Main Methods:

• A cohort of 22 patients with bleeding esophageal varices underwent mesocaval "H" shunt creation.
• The right external iliac vein was utilized as the autogenous vein graft.
• Surgical technique details and patient demographics were recorded. Preoperative endoscopy and intraarterial pitressin infusion were employed in select cases.

Main Results:

• No recurrent variceal bleeding was observed in any patient post-surgery.
• Two postoperative deaths occurred, both in patients with Child-Pugh Class C cirrhosis.
• Minimal and temporary right leg edema was noted; encephalopathy was a significant issue in only three patients with poor hepatic reserve.

Conclusions:

• Mesocaval "H" shunts constructed with autogenous veins provide a highly effective treatment for bleeding esophageal varices.
• The procedure is associated with a low complication rate and excellent long-term patency, as suggested by prior experimental data.
• This surgical option offers a promising solution for managing portal hypertension and preventing variceal re-bleeding.
