Abstract

Purpose

This study aimed to evaluate the usefulness of a coaxial double balloon catheter for simplification of the balloon-occluded retrograde transcatheter obliteration (BRTO) procedure compared with a single-balloon catheter.

Materials and methods

Thirty-three patients who underwent BRTO with a single-balloon catheter (Single-balloon group, n = 15) or a coaxial double balloon catheter (Coaxial group, n = 18) were included, retrospectively. The frequency of additional procedures for stagnation of sclerosant including ethanol injection, coil embolization, and additional balloon occlusion for collateral draining veins; the dose of ethanolamine oleate (EO); and the complication rate and the success rate of sclerosant stagnation were evaluated.

Results

Additional procedures were needed in four patients in the Coaxial group, which was significantly lower than that in the Single-balloon group (nine patients, P = 0.038). The dose of EO in the Coaxial group (11.2 ± 6.6 g) was lower, but not significantly different than that in the Single-balloon group (14.4 g ± 6.1 g, P = 0.184). The complication rate and the success rate of sclerosant stagnation were not different between the two groups.

Conclusion

The use of a coaxial double balloon catheter can simplify the BRTO procedure compared with a single-balloon catheter.
