In order to achieve local control of the solitary recurrent lesion, we resected the remnant breast, which gave us a useful opportunity to examine the previously implanted flap histologically. A 33-year-old Japanese female was diagnosed with T2N0M0 breast cancer in the outer area of her left breast and underwent partial mastectomy with immediate reconstruction using a local adipofascial flap. The breast lesion was considered to be invasive ductal carcinoma, scirrhous carcinoma, lymphatic invasion+, venous invasion-, estrogen receptor+, progesterone receptor+, and HER2/neu-. Involvement was noted in three of the twenty-five resected axillary lymph nodes. She received adjuvant hormone therapy, but developed a solitary local recurrence of the skin forty-five months after the initial procedure, for which she received total mastectomy, systemic chemotherapy, and hormone therapy. During the histological examination of the local adipofascial flap that had been implanted into the partial breast defect, normal fatty tissue and the implanted fascia were seen at the implantation site. This is a rare report in which a local flap that was implanted during oncoplastic breast surgery was histologically examined.展开更多

We used three reverse adipofascial cross finger flaps raised at the same time from 2 fingers to reconstruct adjacent fingers of the patient. The patient recovered well postoperatively and had good range of movement of the fingers. This avoided the complications of the use of regional or distal flaps. To our knowledge, this is the first case reported in which three reverse adipofascial cross fingers flaps are raised at the same time, two of them from an injured finger, to cover three raw areas on two fingers of a patient.展开更多

There was loss of the pulp of the thumb extending circumferentially to the dorsal aspect with loss of the skin of the terminal phalanx and part of the proximal phalanx. The nail and germinal matrix were lost with exposure of the bone and extensor pollicis longus tendon insertion. The thumb was totally covered with a combination of two flaps: Moberg flap with V-Y advancement was used to cover most of the volar surface of the thumb and reverse adipofascial cross finger flap from the adjacent index finger was used to cover the dorsal surface and the tip of the thumb. The reverse adipofascial cross finger flap was covered with split thickness skin graft. Three weeks later this flap was divided and the thumb was mobilized freely. The patient had a full range of movement of the thumb and index finger with few settings of physiotherapy postoperatively. We recommend combining both of these flaps to reconstruct degloving injury of the thumb as they provide near adjacent tissue of similar texture, preserve sensation at the volar aspect of the thumb and also avoid the complications of the distant flaps.展开更多

Methods Four fresh cadaver legs which had been injected with colored latex were dissected under magnification to identify the origin, course an distribution of vessels from the subfascial level to the skin. The adipofascial flap was harvested from the whole medial side of the leg and fascial flap from other leg of the same cadaver. The posterior tibial artery and its first and second supra-malleolus septal arteries were retained in these flaps. Selective injection of China ink through posterior tibial artery was carried out, and dimension of inkstained areas was recorded. Results Three main trunk vessels of the leg gave off branches to deep fascia and subcutaneous tissues, forming a large vascular plexus in the subcutaneous tissues on the deep fascia and a delicate, but dense and well anastomosed vascular plexus beneath the deep fascia. The vascular plexus in the subcutaneous tissues ran deeper than the superficial venous system. The areas stained by selective injection in adipo fascial flaps were larger than those in the fascial flaps. Conclusion Subcutaneous tissues and deep fascia can he considered as an anatomic entity nourished by two very well developed vascular networks which lie on both sides of deep fascia. Incorporation of the deep fascia can not only protect the subcutaneous tissue from being lacerated during raising of the flap, but also enhance vascularity of the adipofascial flap. leaving superficial veins intact while raising the skin flap does not jeopardize the vascular plexus in the subcutaneous tissues and can preserve the superficial lymphatic vessels, so that postoperative edema of the flap or the leg could be avoided.展开更多
