No Doppler Single Position-Lateral Intercostal Artery Perforator Flap (NDSP-LICAP): a Safe and Versatile Flap for Breast Oncoplasty in Resource-Limited Setting

Introduction The lateral intercostal artery perforator flap (LICAP) has emerged as one of the safest and less morbid flaps for lateral and central breast defects. We hereby describe a reproducible no Doppler single position (NDSP) technique to harvest it in single position without handheld Doppler, making it a versatile flap for lateral breast defects in resource-limited setting also. Materials and Methods With this technique, we performed a total of 22 LICAP turnover flaps over a period of 18 months from January 2020 to June 2021. In all 22 cases, the indication of flap was to fill the post-breast conservation surgery (BCS) defects in outer quadrant of breast. All LICAP flaps were harvested by surface marking of anatomical landmarks and without handheld Doppler. Results Out of 22 LICAP turnover flaps, thirteen were harvested for left breast and nine for right breast. The median width and length of the flap were 12.2 cm and 19.6 cm, respectively. The additional mean operative time was 41 min. All LICAP flaps survived well, and grade 1 Clavien-Dindo morbidity was documented in four cases. Mean hospital stay was 2.6 days. All patients received radiotherapy on their stipulated schedule . Early cosmetic outcome was good, and long-term outcomes are awaited. Conclusion NDSP-LICAP flap is a workhorse for lateral breast defects. Precise knowledge of perforators and anatomical landmarks can be used for harvesting these flaps, thus avoiding ultrasound Doppler and dedicated training for perforator localization. This technique has short learning curve without the need for any plastic surgery training. The early cosmetic outcomes are good.
