Comparative assessment of the antirestenotic efficacy of two paclitaxel drug-eluting balloons with different coatings in the treatment of in-stent restenosis.

Background/objectives: Preclinical investigations have suggested that coating technology is crucial for the efficacy of drug-eluting balloons (DEB). Aim of this study is to compare the antirestenotic efficacy of two paclitaxel DEB with different coatings in the treatment of in-stent restenosis (ISR) by means of a morphological and functional assessment.

Methods: In a single center, prospective, non-randomized study, the shellac-paclitaxel coated DIOR, and the urea-paclitaxel coated IN.

Breast cancer surgery without drains: no influence on seroma formation.

It is not clear whether drains are necessary after breast cancer surgery. The purpose of this study was to compare seroma formation in patients that had postoperative drainage for 24 h with patients that had no drain after breast cancer surgery. In this retrospective cohort study 96 patients with a primary breast cancer were included.
