Vein/Arterial Grafts Harvested within the Incision for a Free Groin Flap.

The free groin flap results in less donor-site morbidity than other skin flaps and is suitable for use in children and adolescents. However, the vascular pedicle is relatively short and vessel diameter is small, which makes vascular anastomosis technically difficult. To overcome this limitation, we harvested vein and arterial grafts from the flap elevation area without placing additional skin incisions. Use of short (2-3 cm) vein/arterial grafts greatly simplified flap insetting and vascular anastomosis. This procedure may expand the indications for free groin flap transfer.

Free perivascular tissue flap transfer.

Local flaps and composite grafting are the procedures of choice for reconstructing relatively small soft tissue defects. However, despite their limited conveyable volume, local flaps sometimes require a wide dissection area and long new incisions. Composite grafts also have serious limitations and require a well-vascularized recipient bed. To overcome these limitations, we used a free vascularized perivascular tissue flap based on the descending branch of the lateral femoral circumflex artery. Using this method, we performed reconstructions for seven patients (four cases in head and neck region and three cases in lower limb) with various soft tissue defects (ranged from 4.0 cm(3) to 40.0 cm(3)). This flap was easily elevated, without the need for precise preoperative flap design, and the flap volume was adjustable regardless of whether deep fascia and muscle were included. The flap has a rich vascular supply, which allows bone and cartilage tissue to be combined with the transfer of soft tissue, and satisfactorily treats chronic wounds with poor blood supply.

Covering implantable left ventricular assist device (DuraHeart) with free flap.

Severe donor shortage in Japan makes the waiting period for heart transplantation extremely long and the left ventricular assist devices (LVADs) are often used for bridge-to-transplant. We present three cases of infected and exposed DuraHeart LVAD system treated with free flaps. Four free flaps (two latissimus flaps and two anterolateral thigh flaps) were transferred using the right internal thoracic vessels or left deep inferior epigastric vessels as recipients. The potential significance of the continuous low pressure blood flow generated by the LVAD system on microvascular patency has not been previously reported. All flaps survived and worked efficiently to control the infection and cover the devices. Heart transplantation was conducted in the two of three patients. Free flap transfer is an efficient treatment for the patients with infected and exposed implantable LVAD.

The role of latissimus dorsi myocutaneous flaps in secondary breast reconstruction after breast-conserving surgery.

OBJECTIVE: Secondary reconstruction after breast-conserving surgery is generally challenging because of the nature of irradiated tissue. The aim of this study was to validate the use of latissimus dorsi myocutaneous (LDM) flaps for secondary breast reconstruction after breast-conserving surgery. METHODS: Fifteen consecutive patients who underwent secondary reconstruction with an LDM flap after breast-conserving surgery were included in the study. The esthetic outcome in comparison with the contralateral breast was evaluated by observer assessments consisting of 7 criteria. In addition to comparing pre- and postoperative scores for each criterion, factors affecting overall esthetic outcome were analyzed. RESULTS: There was no major recipient- or donor-related complication. In 13 patients, the skin paddle of the LDM flap was exposed to the skin surface. In all patients, overall esthetic scores increased postoperatively. Age, period between breast-conserving surgery and LDM flap, body mass index, or preoperative breast size did not affect the overall esthetic outcome. Tumors in the lower quadrants tended to result in poorer esthetic scores, especially in breast shape and scar (P = .04 and .02, respectively). CONCLUSIONS: Given their high vascularity and moderate flap volume, LDM flaps could be a reliable option for secondary breast reconstruction after breast-conserving surgery. Although exposure of skin paddle to the skin surface is inevitable in most cases, esthetic improvement could be achieved, including the breast scar. On the contrary, immediate reconstruction would certainly be more desirable, especially in cases of tumors in the lower quadrants.

[Case of bilateral pneumothorax observed during the administration of gefitinib for lung adenocarcinoma with multiple pulmonary metastases].

A 61-year-old woman who had never smoked was given a diagnosis of adenocarcinoma of the lung with multiple pulmonary metastases. Systemic chemotherapy consisting of carboplatin and paclitaxel was not effective, thereafter daily oral administration of gefitinib was initiated. Six days later, bilateral pneumothorax was found. The extent of the pneumothorax was slight and she recovered without drainage within about one month although treatment of gefitinib was restarted. Gefitinib was effective for lung cancer in this case. Bilateral pneumothorax is a rare complication of chemotherapy for lung cancer. Only 3 such cases under treatment with gefitinib were reported in Japan.
