Modified chest wall lateral intercostal artery perforator (MCW-LICAP) flap: a versatile flap in the era of...

Breast reconstruction following oncological resection is becoming more common in recent years. In some ladies, implant reconstruction is not ideal due to significant implant visibility or palpability. Autologous reconstruction addresses the limitations of implant reconstruction but results in potential donor site morbidities. To date, there is no clear advantage ascribed to any technique. With appropriate selection, patients with adequate lateral mammary fold have the option of reconstruction with MCW-LICAP flap. We present our techniques and outcomes from a series of 29 patients who underwent MCW-LICAP flap.

A retrospective review of consecutive patients who underwent curative resection for breast cancer with immediate MCW-LICAP flap reconstruction, between July 2018 to April 2022 was conducted. The techniques used with its variations along with video demonstrations are presented.

A total of 29 patients underwent 34 procedures. Nineteen breast conserving surgeries and 15 mastectomies were completed, and immediate reconstruction performed in all cases. Twenty-three patients had MCW-LICAP, 1 with a Stacked intercostal artery perforator (STICAP) flap, and 5 had MCW-LICAP combined with a Goldilocks mastectomy. There were no cases of complications requiring re-operation. All patients had acceptable time to adjuvant therapy with a median of 36 days. Learning curve analysis showed a significant reduction in operative time after the 6th case.

In our preliminary experience, MCW-LICAP flap is a safe, reliable, and versatile oncoplastic reconstruction option.
