What is Optimal Post-operative Prophylactic Therapy in Irradiated Breasts Undergoing Repeat Surgery

• Status: Not yet recruiting
• Trial end date: 2025-12-31
• Target enrollment: 0
• Participant gender: Female

Summary

This study will look at whether females who have previously had breast surgery and radiation and are undergoing repeat breast surgery require any post operative interventions. The reason the investigators are conducting this study is because females who have undergone breast radiation are at higher risk of wound complications following breast surgery. The investigators will randomize recruited female participants into three arms, one which is post operative antibiotics for one week, one which is a wound VAC, and one which is no intervention. The investigators goal is to identify whether these patients will require any postoperative interventions.
