Postoperative ultrasound-guided percutaneous placement of a new breast brachytherapy balloon catheter.

Background: The optimal technique and timing for the implantation of a recently developed breast brachytherapy balloon catheter (MammoSite; Proxima Therapeutics, Alpharetta, Georgia) have not been well defined. We hypothesized that placing this postoperatively, utilizing percutaneous ultrasound-guided placement, would be preferable.

Methods: Patients who met eligibility requirements for breast brachytherapy were implanted with the MammoSite device utilizing percutaneous ultrasound-guided technique.
