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
Learn key points about Gastric Variceal Hemorrhage (GVH) including its frequency in cirrhotic patients, severity compared to esophageal variceal hemorrhage, and differences in management from EVH.
