Purpose: Conventional balloon-occluded retrograde transvenous obliteration often fails to achieve complete occlusion in cases with complex collateral drainage, leading to variable outcomes. The cooperative anti-reflux and double interruption system, a coaxial dual-balloon device, was developed to achieve more stable venous occlusion. This study aimed to evaluate the clinical and hepatic functional benefits of double-balloon balloon-occluded retrograde transvenous obliteration compared with the conventional single-balloon method for gastric varices.
Aoki et al. (Tue,) studied this question.
