Résumé
The profunda femoris artery perforator (PAP) flap is gaining popularity in microsurgical reconstruction. The complications that can occur after the PAP flap harvest include donor-site lymphedema, seroma, or cellulitis. The aim of this study was to evaluate and establish a safer technique for the elevation of lymphatic vessels preserving profunda femoris artery perforator (LpPAP) flap using pre- and intraoperative ICG lymphography. In this article, we also evaluate the anatomical relationship between the PAP flap and lymph-collecting vessels. From July of 2018 to January of 2019, 24 patients with soft tissue defects after tumor resection underwent reconstruction using PAP flaps. The lymph-collecting vessels at the medial thigh area were identified using pre- and intraoperative ICG lymphography. A PAP flap was elevated taking care not to damage lymph-collecting vessels. After flap elevation, the anatomical correlation between lymph-collecting vessels and the anterior edge of the gracilis muscle was measured. The postoperative complications were assessed. PAP flaps survived completely in all cases. In all cases, using intraoperative ICG lymphography, surgeons confirmed that the lymph-collecting vessels in the medial thigh region were left intact. There were no donor site complications such as lymphedema, lymphorrhea, or cellulitis. The elevation technique of an LpPAP flap is effective in reducing the risk of damage to lymph-collecting vessels, and thus reducing chances of postoperative lymphorrhea or iatrogenic lower limb lymphedema.

BACKGROUND AND OBJECTIVES
OBJECTIVE
The profunda femoris artery perforator (PAP) flap is gaining popularity in microsurgical reconstruction. The complications that can occur after the PAP flap harvest include donor-site lymphedema, seroma, or cellulitis. The aim of this study was to evaluate and establish a safer technique for the elevation of lymphatic vessels preserving profunda femoris artery perforator (LpPAP) flap using pre- and intraoperative ICG lymphography. In this article, we also evaluate the anatomical relationship between the PAP flap and lymph-collecting vessels.
METHODS
METHODS
From July of 2018 to January of 2019, 24 patients with soft tissue defects after tumor resection underwent reconstruction using PAP flaps. The lymph-collecting vessels at the medial thigh area were identified using pre- and intraoperative ICG lymphography. A PAP flap was elevated taking care not to damage lymph-collecting vessels. After flap elevation, the anatomical correlation between lymph-collecting vessels and the anterior edge of the gracilis muscle was measured. The postoperative complications were assessed.
RESULTS
RESULTS
PAP flaps survived completely in all cases. In all cases, using intraoperative ICG lymphography, surgeons confirmed that the lymph-collecting vessels in the medial thigh region were left intact. There were no donor site complications such as lymphedema, lymphorrhea, or cellulitis.
CONCLUSION
CONCLUSIONS
The elevation technique of an LpPAP flap is effective in reducing the risk of damage to lymph-collecting vessels, and thus reducing chances of postoperative lymphorrhea or iatrogenic lower limb lymphedema.
