Predesigned chimeric deep inferior epigastric perforator and inguinal lymph node flap for combined breast and lymphedema reconstruction: A comprehensive algorithmic approach.

The combined use of a deep inferior epigastric perforator (DIEP) flap coupled with vascularized inguinal lymph nodes (VILNs) for simultaneous breast and lymphedema reconstruction has already been well established, and promising results have been reported. However, a standardized approach for the planning and shaping of this combined flap is still lacking. We aimed to propose a comprehensive algorithmic approach for delayed unilateral breast and lymphedema reconstruction using a predesigned abdominal flap associated with inguinal lymph node transfer. We present in detail the preoperative measurements and surgical technique of the chimeric flap, which combines a predesigned DIEP template and a preselected inguinal lymph node flap, based on the preoperative computed tomography angiography and SPEC-CT findings, respectively; four different flap types are described according to the location of the pedicles of the two flap components. Our results of a series of 34 consecutive female patients with unilateral mastectomy and arm lymphedema, who underwent this combined predesigned reconstructive procedure, are retrospectively analyzed and reported. We recorded a high survival rate of the chimeric flaps in our series, with only one case of partial ischemic loss of a DIEP skin island. In the majority of our patients, the pedicles of the combined flaps were located in opposite positions. After a mean 35-month follow-up, we recorded a 47% mean volume difference reduction of the lymphedematous compared to the unaffected arm; no donor-site lymphedema was documented. Self-evaluation questionnaires showed high patient satisfaction rates regarding breast reconstruction. This algorithmic approach provides standardized guidance for accurate design and transfer of the DIEP-VILN chimeric flap while achieving highly satisfactory outcomes for both breast and lymphedema reconstruction.

Simultaneous upper limb melanoma and breast cancer related lymphedema management.

We present a rare case of a patient with malignant melanoma in the lymphedematous arm associated with breast cancer and its lymphedema management. Histology of previous lymphadenectomy and results of current lymphangiographies suggested the need for SLN biopsy, and simultaneously perform of distal LVAs to manage lymphedema.
