We aimed to compare duration of uterine artery embolization, radiation exposure, safety and quality of life associated with the procedure in patients undergoing uterine artery embolization using transradial and transfemoral access. METHODSThis randomized controlled trial was conducted from February 2013 to March 2017 in three hospitals. Transradial access was used in 78 patients and transfemoral access in 75 patients. Clinical characteristics of the patients were comparable between the two groups. Patients were evaluated for the success and duration of the procedure, radiation exposure, major and minor complications. Quality of life associated with the procedure was assessed among patients with uterine fibroids. RESULTSEmbolization procedures were successfully performed in all patients in both groups. The duration of uterine artery embolization (32.27±7.99 vs. 39.24±9.72 minutes, p < 0.001), uterine artery catheterization time (12.36±5.73 vs. 19.08±6.06 minutes, p < 0.001) and radiation exposure (0.28±0.14 vs. 0.5±0.21 mZv, p < 0.001) were significantly lower in the transradial access group. The rate of major (0% vs. 2.7%, p = 0.37) and minor (11.53% vs. 17.3%, p = 0.42) complications was comparable between the two groups. Transradial access was associated with a statistically significant improvement in the quality of life associated with the procedure among patients with uterine fibroids. CONCLUSIONTransradial access in uterine artery embolization has the same efficacy and safety compared to transfemoral access. This access reduces radiation exposure and duration of the procedure.

The prevalence of peripheral arterial disease requires the search for an optimal solution for preserving blood flow by using devices of various modifications. Drug-coated balloons are widely used in the surgical treatment of peripheral arterial disease. The article aims at the summarization of the study results on the efficacy and safety of the various drug-coated balloons, in particular, with paclitaxel, in the treatment of steno-occlusive lesions in the peripheral arterial disease. Comparing the study results is fraught with certain difficulties, given the differences in the study endpoints, the demographic characteristics of patients and the lesion patterns. Nevertheless, the study results of percutaneous transluminal angioplasty (PTA) with drug-eluting ballons on the femoropopliteal segment are superior to the results obtained using conventional PTA and other endovascular interventions in the same vascular bed. PTA with drug-eluting balloons has a Class 1 recommendation in accordance with the issued recommendations of the SCAI (Society for Cardiovascular Angiography and Interventions). However, conducting PTA with paclitaxel-eluting balloons requires further determination of the possibilities of its use.
