Cumulative ascites exacerbation rate was significantly higher in group A than B ( p = 0.005), B1 ( p = 0.03), and B2 ( p = 0.03). GV recurrence rate was not significantly different between group A and B ( p = 0.5) or between group A, B1 and B2 ( p = 0.1). GV bleeding rate after BRTO was significantly higher in group B2 than in group A (20% vs 0%, p = 0.04). Complete GV thrombosis was significantly lower in group B2 (50%) than in A (89.5%, p = 0.01) and B1 (100%, p = 0.01). Median volume of ethanol amine oleate iopamidol (EOI) was significantly higher in group A than in group B2 (14.8 Vs 7.4 ml, p = 0.03). Group B was sub-grouped into group B1 (11 patients underwent selective BRTO) and group B2 (10 patients underwent superselective BRTO). The aim of this study is to compare outcome after different BRTO techniques, i.e., conventional, selective and superselective techniques.įifty-nine consecutive patients underwent BRTO as a primary prophylactic treatment for GV were retrospectively categorized into group A (38 patients underwent conventional BRTO) and group B (21 patients underwent selective or superselective BRTO). Balloon-occluded retrograde transvenous obliteration (BRTO) is a well-established interventional radiological technique for treatment of isolated gastric varices (GV).
