Transhepatic embolization of varices

W C Widrich, A H Robbins, D C Nabseth

    Cardiovascular and Interventional Radiology
    |January 1, 1980

    Summary

    Percutaneous transhepatic embolization of varices (PTEV) effectively controls acute variceal bleeding, especially in severe cases. While PTEV is a safe, temporary measure, surgical shunts are recommended for long-term control due to recurrence rates.

    Area of Science:

    • Gastroenterology
    • Interventional Radiology
    • Hepatology

    Background:

    • Variceal bleeding is a serious complication of portal hypertension.
    • Pitressin perfusion is often insufficient for severe cases, particularly in Child's Class C patients.
    • Effective hemostasis is crucial for patient survival and management.

    Purpose of the Study:

    • To evaluate the efficacy and safety of percutaneous transhepatic embolization of varices (PTEV) in controlling acute variceal bleeding.
    • To compare the effectiveness of different embolic agents.
    • To assess the role of PTEV as a bridge to definitive surgical treatment.

    Main Methods:

    • PTEV was performed using Gel-Foam soaked in sodium tetradecyl sulfate.
    • The procedure was utilized in patients with variceal bleeding not controlled by other means.
    • Outcomes included acute bleeding control rates and recurrence rates.

    Main Results:

    • PTEV achieved acute variceal bleeding control in 71-95% of patients.
    • Gel-Foam with sodium tetradecyl sulfate was more effective than bucrylate (43-57% control).
    • One-year and two-year recurrent bleeding rates were 30% and 37.5%, respectively.

    Conclusions:

    • PTEV is a safe and effective procedure for acute variceal bleeding, particularly in high-risk patients.
    • It serves as a valuable temporizing measure, allowing for elective surgical intervention.
    • Long-term management necessitates a surgical decompressive shunt in addition to PTEV to prevent recurrence.
