Balloon-occlusion catheter rupture during balloon-occluded retrograde transvenous obliteration of gastric varices utilizing sodium tetradecyl sulfate: incidence and consequences. | LitMetric

AI Article Synopsis

  • Balloon-occluded retrograde transvenous obliteration (BRTO) is a successful method for treating bleeding gastric varices, primarily using ethanolamine oleate in Asia, with a high success rate of 95% for procedures and 85% for obliteration of varices.
  • In a study involving 41 BRTO procedures, complications included a 4.9% overall complication rate, with 6 instances of balloon ruptures occurring, affecting technical and obliterative success rates.
  • The incidence of balloon ruptures using 3% sodium tetradecyl sulfate in the U.S. was found to be significantly higher than in Asia, but these ruptures did not significantly impact the overall technical or clinical outcomes.

Article Abstract

Balloon-occluded retrograde transvenous obliteration (BRTO) is an established procedure for the management of bleeding gastric varices in Asia. Invariably, the sclerosant utilized in Asia is ethanolamine oleate and the inventory used (vascular sheaths, balloon-occlusion catheters, and microcatheters) is not available outside Asia. A total of 41 BRTO procedures were performed with a technical and obliterative (gastric varix obliteration) success rate of 95% (n = 39 of 41) and 85% (n = 35 of 41), respectively. Complications were 4.9% (n = 2/41). A total of 6 balloon ruptures occurred (14.6%, n = 6 of 41). One rupture (16.7%, n = 1 of 6 of ruptures) lead to a technical failure and 2 ruptures (33.3%, n = 2 of 6 of ruptures) lead to an obliterative failure. Balloon rupture contributed to 50% of technical failures (n = 1/2, P = .274) and 33% of obliteration failures (n = 2/6, P = .148). In conclusion, the incidence of balloon-occlusion catheter rupture utilizing 3% sodium tetradecyl sulfate (STS) and inventory unique to the United States is significantly higher than in Asia (<8% rupture rate). However, these ruptures have no significant technical or clinical consequences.
