    Study Notes

    Gastric Variceal Hemorrhage (GVH)

    • 25-30% of cirrhotic patients with portal hypertension experience Gastric Variceal Hemorrhage (GVH)
    • Gastric varices (GV) tend to bleed more severely but less frequently compared to esophageal varices (EV)

    TIPS Limitations

    • TIPS often fails to control rebleeding in GVH due to large shunts and inadequate decompression of gastric varices
    • The main limitation of TIPS in managing GVH is its inability to directly target and obliterate the gastric variceal complex
    • TIPS may not effectively decompress gastric varices due to proximity and throughput issues
    • TIPS can lead to rebleeding through alternative channels even after initial hemostasis

    B-RTO Advantages

    • Balloon-occluded retrograde transvenous obliteration (B-RTO) is a promising management approach for GVH, particularly for large shunts
    • B-RTO has higher technical and clinical success rates and lower GV rebleed rates compared to TIPS
    • The main advantage of B-RTO over TIPS is its ability to directly target and obliterate the gastric variceal complex

    Gastric Variceal Hemorrhage Management

    • Combination therapy with B-RTO and TIPS shows promise for better outcomes in managing GVH
    • B-RTO emerges as a preferred option for managing GVH due to its high technical and clinical success rates and low GV rebleed rates
    • Proximity and throughput issues are key concepts that explain why TIPS often falls short in controlling rebleeding of gastric varices compared to esophageal varices
