Simultaneous combined balloon-occluded retrograde transvenous obliteration and partial splenic embolization for gastric fundal varices.

ABSTRACT

BACKGROUND: We previously reported the techniques and usefulness of simultaneous combined balloon-occluded retrograde transvenous obliteration (B-RTO) and partial splenic embolization (PSE), based on the hypothesis that concomitant PSE can diminish the increase in portal venous pressure after B-RTO. OBJECTIVE: After experiencing more cases and performing longer-term follow-up, we re-evaluated the efficacy of simultaneous combined B-RTO and PSE for gastric fundal varices (GVs). METHODS: We performed B-RTO in 36 consecutive patients treated for GVs from 2005 to 2013. Twenty-three patients underwent simultaneous combined B-RTO and PSE (Group 1) and 13 underwent B-RTO monotherapy (Group 2). The outcomes were retrospectively evaluated. RESULTS: There were no significant differences in baseline characteristics between the two groups except that the splenic volumes were larger in Group 1 than 2. B-RTO was technically successful in 21 of 23 patients (91.3%) in Group 1 and in 12 of 13 patients (92.3%) in Group 2. In all patients with ruptured GVs (six in Group 1 and five in Group 2), complete hemostasis was obtained by B-RTO. Exacerbation of esophageal varices was significantly less frequent in Group 1 than 2 (p = 0.0017). CONCLUSION: Concomitant PSE with B-RTO may contribute to prevention of the exacerbation of esophageal varices after B-RTO.
