The Intercostal Artery Perforator Flap: Expanding Breast-Conserving Therapy With a Modified Oncoplastic Approach.

Lumpectomy reconstruction using ICAP flaps can effectively expand breast conservation therapy indications in resection of breast skin, nipple-areola, or large volume defects. This technique is adoptable and of limited complexity. Enhancing breast-conserving surgery may improve outcomes compared with mastectomy reconstruction. Intercostal artery perforator patients may require fewer opioids, shorter hospital stays, and lower operative burden.
