coil assisted retrograde transvenous obliteration

ConclusionĬARTO-II was feasible and safe and could be performed relatively quickly. The recurrence rate of GV during follow-up was 2.8% (mean follow-up, 207 days). Contrast-enhanced computed tomography after CARTO-II confirmed complete variceal thrombosis in all cases. Mean length of the procedure was 132.8 min. The mean number of metallic coils used per procedure was 3.36. No patients experienced severe complications such as coil migration or pulmonary embolization. In all patients, GV sclerosis, coil placement and removal of the balloon catheter were successfully completed. Technical and clinical success rates, number of coils used, presence or absence of severe complications, timing of the procedure, and rate of GV recurrence after the procedure were analyzed retrospectively. CARTO-II was performed with ethanolamine oleate iopamidol, and the balloon catheter was immediately removed after coil placement. In the CARTO-II procedure, coil embolization of the drainage vein was performed “after” injection of the sclerosant to prevent migration of the sclerosant. In the CARTO procedure, coil embolization of the drainage vein is performed “before” injection of the sclerosant to replace the use of balloon catheter. Thirty-six consecutive patients who had undergone CARTO-II between June 2016 and April 2018 were included in the study. To investigate the technical feasibility, safety and clinical outcomes of coil-assisted retrograde transvenous obliteration II (CARTO-II) for gastric varices (GV).
