Microvascular anastomosis with suture technique is a basic skill but there are several problems such as stenosis, thrombosis and long operating time. Recently plastic surgeons have developed non-suturing mechanical coupling devices for microvascular anastomosis. The authors applied non-penetrating vascular clips (VCS clips) in the field of free flap surgery of head and neck area. Between August of 2004 and January of 2005, we performed 9 free flaps (16 vessels) using small-sized VCS clips. Four stay sutures were applied first and then VCS clips were placed between sutures about 1 mm apart. Vascular pedicle of free flap included the descending branch of lateral circumflex femoral vessel, thoracodorsal vessel, deep inferior epigastric vessel and cephalic vein. The recipient vessels were the superior thyroid artery, superficial temporal artery, internal jugular vein, external jugular vein, and superficial temporal vein. We performed 13 end-to-end (4 arteries and 9 veins) and 3 venous end-to-side anastomoses. No flap related complication occurred but we applied additional clips or sutures in two cases due to blood leakage after completion of anastomosis. Primary patency rates seemed to be good and more rapid anastomosis could be done than conventional suture technique. Advantages of VCS technique are high patency rate, low thrombogenecity and rapidity. Although the high cost of VCS instrument may be a problem, this clip could be applied safely in microvascular free tissue transfer.

Reconstruction of the composite mandibular defect resulting from ablative resection of tumor involved jaw has been challenging task to the plastic surgeon. A wide variety of different techniques were used with limited success until the advent of microsurgery. The high success rate of microsurgical procedures has allowed for significant improvement in both functional and aesthetic results. A variety of free flap donor sites have been used successfully for mandibular reconstruction. Between April of 1991 and August of 1998, 20 mandibular reconstructions were performed for oncologic defects. 4 patients underwent mandibular reconstruction with pectoralis major flap, 3 patients with free nonvascularized bone graft, 1 patient with metal plate. 12 patients underwent microvascular mandibular reconstruction(8: fibula, 4: ilium). The type of free flap was determined by the requirements of the defect. Satisfactory aesthetic and functional results were achieved in all cases without significant complications. So microvascular mandibular reconstruction should be considered as primary choice in all mandibular defect without hesitation.
One hundred & seventy four consecutive free-flap transfers were reviewed to analyze distribution of the type of reconstructions, kinds of donor flaps as well incidence of complications. The role of emergent exploration and the effect of preoperative wound conditions in flap survival were evaluated. Free flap transfer for head and neck reconstruction was most common as 93 cases, followed by for upper extremity of 30 cases, for lower extremity 30 cases, 18 penile reconstructions and for trunk & breast 3 cases. Nine flaps exhibited signs of ciruclatory insufficiency between 5 hours and 7 days. Three were managed conservatively with ultimate partial necrosis of the flaps. Eight flaps required return to the operating room. On exploration, early arterial occlusion was revealed in 1 flap, late arterial occlusion in 2 flaps, early venous occlusion in 1 flap, late venous thrombosis in 2 flaps, prolonged venous spasm in 1 and hematoma in 1 flap. The average time from the first abnormal examination to exploration was 2.6 hours. There were no false-positive explorations. Four free flaps failed in spite of the correction of the cause of circulatory compromise. The remaining 4 flaps were salvaged following the correction the casuse. Recipient vessel problems such as irradiation and infection were the most common cause of circulatory crisis. Among the eight flaps requiring return to the operating room, single vein was anastomosed in three flaps and two veins in the remaining five. In the totally failed four flaps only single vein was anastomosed in three cases. The results of this study demonstrate the efficacy of clinical monitoring and the role of early exploration. Precautious selection of recipient vessels and two vein anastomosis are recommended for safe and better prognosis.
Purpose: Breast reconstruction with abdominal flap has many advantages. However, it might cause abdominal complications such as bulging or hernia. SIEA (Superficial inferior epigastric artery) flap is the most advanced form of abdominal flap which has no adverse effect on abdominal fascia. We report 2 cases of breast reconstruction with SIEA flap with reference review. Methods: From Jun 2006 to Jan 2009, 110 patients underwent breast reconstruction with free abdominal flap. We tried to find the SIEA in every cases and adopted SIEP flap if the diameter was larger than 1mm and it had visible pulsation. 2 patients underwent breast reconstruction with SIEA flap. After design of abdominal flap SIEA was investigated with portable Doppler. SIEA was usually found 4-5 cm lateral to the midline. Flap was elevated with SIEA and SIEV to their maximal length at hiatus. Results: There were no complications, such as infection, hematoma, and necrosis of flap. In both cases, flaps survived completely with excellent vascularity and breast reconstruction was successful. In one case, there was skin necrosis of mastectomy flap, and it was healed by conservative management. Conclusion: With the SIEA flap, donor site morbidity can be minimized along with reduction of operation time. If there is reliable SIEA, SIEA flap would be the preferred skills. However, the limitation of the SIEA flap is difficulty in identifying the SIEA. The reason for less availability of the flap in Korea might include high prevalence of the Caesarian section scar and relatively higher level of the lower margin of the flap.

Emergency free flap has been advocated to cover the severely injured extremity for more than two decades, due to its numerous advantages such as low incidence of flap failure and infection rate and early recovery of function. But there are very few reports about these. The authors report their experience in using the emergency free flap for reconstruction of extremities. For last 10 years, 4 patients ranging from 3 to 27 years old with severely traumatized extremities were treated with emergency free flap transfers. Three were males and the other was a female. Flap size ranged from $2{\times}5\;cm^2$ to $7{\times}22\;cm^2$. The locations of the recipient site were the dorsum of the foot, the cubital fossa, the popliteal fossa and the upper arm. The number of the donor sites used was as follows: one scapular flap, two parascapular flaps, and one radial forearm flap with the radial bone. All of the flaps survived without need of re-exploration. There was no infection or flap loss. Involved joints have recovered a normal range of motion. Therefore, we consider that the emergency free flap is a very safe and reliable method to cover the severely injured extremities.
Purpose: To report the clinical results of the use of arterialized venous free flaps in reconstruction in soft tissue defects of the finger and to extend indications for the use of such flaps based on the clinical experiences of the authors. Materials and Methods: Eighteen patients who underwent arterialized venous free flaps for finger reconstruction, between May 2007 and July 2009 were reviewed retrospectively. The mean flap size was 4.7${\times}3.2$ cm. The donor site was the ipsilateral volar aspect of the distal forearm in all cases. There were 8 cases of venous skin flaps, 5 cases of neurocutaneous flaps, 4 cases of tendocutaneous flaps, 1 case of innervated tendocutaneous flap. The vascuality of recipient beds was good except in 4 cases (partial devascuality in 2, more than 50% avascuality (bone cement) in 2). Results: All flaps were survived. The mean number of included veins was 2.27 per flap. Mean static two-point discrimination was 10.5 mm in neurocutaneous flaps. In 3 of 5 cases where tendocutaneous flaps were used, active ROM at the PIP joint was 60 degrees, 30 degrees at the DIP joint and 40 degrees at the IP joint of thumb. There were no specific complications except partial necrosis in 3 cases. Conclusions: An arterialized venous free flap is a useful procedure for single-stage reconstruction in soft tissue or combined defect of the finger; we consider that this technique could be applied to fingers despite avascular recipient beds if the periphery of recipient bed vascularity is good.
The purpose of this study was to present the clinical significance of rectus abdominis free muscle flap for large sized diabetic ulcer and necrosis of the foot to salvage limb. From June 2000 to February 2006, eleven patients were included in our study. There were seven males and four females with a mean age of 58.3 years (48~65) at the surgery. All had a history of diabetics and subsequent huge soft tissue defect caused by necrotizing abscess formation around the foot and the ankle. After complete debridement of large sized, infected necrotic tissue, susceptible intravenous antibiotics and wound care were done. After control of infection, confirmed by clinical and laboratory findings, the rectus abdominis free muscle flap was applied to cover remained large soft tissue defect and to prevent the recurrence of infection. All flaps survived and it provided satisfactory coverage for the soft tissue defect on the foot and the ankle area for a mean of 41.1 months (24~85) follow up period. All except of one patients did not have any recurrence of infection on the operation site and could salvage their limbs. The rectus abdominis free muscle flap could be recommended for large sized soft tissue defect after necrotizing abscess in diabetic foot to salvage major limb.

In alveolar deformity of cleft patient, the flap design is very important to make the functional and esthetic outcome. Especially in bilateral cleft alveolus with wide defect, deficiency of covering tissue is a greatest problem. Wound dehiscence may develop oronasal fistula of palatal and labial region and loss of the bone graft. We report 2 cases with bilateral cleft alveolus. In both case, bilateral buccal mucosal flap was used for closure of bilateral cleft alveolus with wide defect. The one was operated with iliac bone graft according to secondary grafting method, the other was closed without bone grafting. The patient was 3 years old. So, secondary alveolar bone graft will be required some years later for the establishment of bony continuity and esthetic advantage. In both cases, we found the entire soft tissue closure without the lack of covering flap. In these case, the closure of alveolus defect was accomplished successfully by the use of bilateral buccal mucosal flap. There was no complication, secondary fistula. The most important thing is the tension-free closure of the bilateral buccal mucosal flap. So, we report these cases with literatures.
Large soft tissue defect of the ankle and foot can present a difficult reconstructive problem to the surgeon. Local musculocutaneous, local fasciocutaneous or free flap is usually the first choice for providing soft tissue coverage. However, in certain situations, local flaps from the same leg and free flap may not be suitable. These include extensive soft tissue injury, where no suitable recipient vessels can be found, previous local fasciocutaneous flap or free flap failure. In such cases, we have utilized the septocutaneous(fasciocutaneous) branch flap of posterior tibial artery from the opposite healthy limb. We present 5 cases of cross leg flaps, which have been modernized with current understanding of vascular anatomy and current fixation technology. All cross leg flaps were based on the axial blood supply of the fasciocutanous branch of the posterior tibial artery. Cross-clamping with bowel clamp was used to create intermittent periods of ischemia. Adjacent lower extremity joints were exercised during the periods of attachment. The results have been quite encouraging. We conclude that the cross leg flap using septocutaneous flap and cast immobilization can be successfully and expeditiously used to cover defects of the ante and foot.
Purpose : Various free flaps and pedicled island flaps are effective for reconstruction of soft tissue defect developed after tumor excision. We want to know the advantage of dorsalis pedis island flap for reconstruction of soft tissue defect caused by soft tissue tumor excision. Materials and Methods : Between 1992 and 2002, we performed 4 dorsalis pedis island flap procedure for reconstruction of soft tissue defect of lower limb developed after soft tissue tumor excision. Average age was 54.7 years old $(40{\sim}68)$, and male 2 cases, female 2 cases. The kinds and number of soft tissue tumors were 2 squamous cell carcinoma and 2 malignant melanoma. The procedures that we performed were all dorsalis pedis island flap. The analysis for the result of treatment was retrospectively accessed by physical examination and questionnaire for whether the change of symptom after operation, range of adjacent joint motion. Also we reviewed associated complication after operative treatment. Results : All dorsalis pedis island flaps were alive. There is no problem for activity of daily living, no skin necrosis and no limitation of motion of adjacent joint. In 1 case of them, the patients died of distant metastasis. Conclusion: Dorsalis pedis island flap procedure as a pedicled island flap procedure is very effective and easy operative procedure for reconstruction of soft tissue defect of lower limb developed after tumor excision compared to free flap procedure because there is no need for microvascular surgery, we can obtain relatively large flap and the lesion and flap donor site locate in the same limb.
