Abstract
BACKGROUND
Over the years, the improvements in microsurgical field allowed the reconstruction of increasingly larger and more complex defects. In this context, we conceived linking more flaps with a single vascular supply. The double free flaps with intra-flap anastomosis offer a better match with recipient site requirements, still having a minimal donor and recipient site morbidity. In the present paper, we describe our experience with this procedure, focusing on its features and providing a collection of cases in different areas and clinical settings.
PATIENTS AND METHODS
Consecutive single-center case series with 16 patients who received defect reconstruction using double free flaps with intra-flap anastomosis between February 2019 and August 2021. The median age was 58 years old (range 39-77). Nine patients were men and seven were women. The defects were located throughout the body, including breast, head and neck, lower and upper limbs. In 12 cases, the cause of the defect was surgical removal of a tumor, while in four cases the cause was trauma. The main indication for this procedure was related to the need of covering a large defect, either in terms of volume or surface, resorting to only one vascular axis.
RESULTS
A total of 32 flaps were harvested, including 10 different techniques. The flaps size ranged from 6 × 3 cm to 24 × 8 cm. Eleven patients completely healed without any complications. No flaps were lost. Three patients developed a minor wound dehiscence and one a wound infection treated conservatively with antibiotic therapy. One patient experienced both of these complications. The median follow up was 12 months and ranged between 6 and 24 months. At the final clinical evaluation, the reconstructive result was stable in all cases and all the patients had a complete resumption of their daily activities.
CONCLUSIONS
Double free flaps reconstruction with intra-flap anastomosis represents a valid and reliable option for the coverage of complex defects in case of depleted recipient sites. This procedure allows us to transfer high amounts of tissue resorting to a single vascular axis. However, it represents a technical challenge and a highly experienced microsurgical team is required.
