  • Calcific myonecrosis is a rare condition in which hypoperfusion due to compartment syndrome causes soft tissue and muscle to become calcified. As calcific myonecrosis gradually deteriorates, secretions steadily accumulate inside the affected area, forming a cavity that is vulnerable to infection. Most such cases progress to chronic wounds that are unlikely to heal spontaneously. After removing the calcified tissue, the wound can be treated by primary closure, flap coverage, or a skin graft. In this case, a 72-year-old man had extensive calcific myonecrosis on his left lower leg, and experienced swelling and increasing tenderness. After removing the muscle calcification, we combined two anterolateral thigh free flaps, which were harvested from the patient's right and left thigh, respectively, to reconstruct the wound with a dead-space filler and skin-defect cover at the same time. The patient recovered without revision surgery or major complications.

  • Purpose: The concept and development of perforator free flaps have led to significant advances in microsurgery. Ongoing developments in perforator free flap surgery are aimed at reducing complications and improving surgical outcomes. The aim of this study was to evaluate the effectiveness and application of supermicrosurgery in free flap surgery. Materials and Methods: A total of 267 patients with soft tissue defects of the lower extremity due to various etiologies from January, 2007 to January, 2013. The patients received either an anterolateral thigh free flap (n=83), a superficial circumflex iliac artery free flap (n=152), an upper medial thigh free flap (n=19), or a superior gluteal artery perforator free flap (n=13). Microanastomosis was performed using a perforator-to-perforator technique, either end-to-end or end-to-side. Results: The mean postoperative follow up period was eight months (range: one to 16 months) and flap loss occurred in 11 cases out of 267. All cases of flap loss occurred within two weeks of surgery due to either arterial insufficiency (n=5) or venous congestion (n=6). Conclusion: Supermicrosurgery enables the selection of the most efficient perforator for microanastomosis at the defect site. It also reduces the time required for dissection of recipient vessels, and reduces the possibility of injury to major vessels. Microsurgery using a vessel of less than 1 mm has been reported to increase the risk of flap failure; however, using the most advanced surgical tools and developing experience in the technique can produce success rates similar to those found in the literature.

  • The use of the implantable Doppler device eases the burden of free flap monitoring, and allows caregivers to notify healthcare personnel of a potential vascular event. A 24-year-old female patient underwent anterolateral thigh adipofascial flap surgery to provide a buried flap on the left temporal area for a depressed and infected skull wound. The author was able to salvage the flap from two venous occlusions, which was made possible by early notifications from the caregiver who reported changes in the Doppler signal.

  • With the recent development in microsurgery, the use of a perforator flap has been widely implemented. If the length of the ALT flap pedicle is insufficient despite adequate preoperative planning, pedicle length extension is necessary. We planned for a reverse ALT free flap using the distal vessel of the descending branch for pedicle length extension in the case of ALT perforator branch originating from the proximal portion of the descending branch. For the management of venous congestion, the distal venae comitantes were anastomosed to the proximal venous stump in an antegrade manner, successfully resolving the venous congestion. Modified reverse-flow ALT free flap, wherein the venae comitantes are anastomosed to the proximal vein stump, is a good option that allows for relatively simple pedicle extension within the same operative field when securing an adequate pedicle length is difficult because of the origin of the perforator from the proximal descending branch, unlike the initial surgical plan.

  • Inevitable immobilization after surgery on lower extremities can induce chronic constipation. Elderly diabetic women usually express ambiguous gastrointestinal symptoms and signs. We present here a case of panperitonitis developed from severe fecal impaction in an elderly diabetic woman after hand reconstruction using material harvested from the lower extremities. A 68-year-old diabetic female underwent anterolateral thigh free flap and wound revision twice on the left thumb. Three weeks after surgery, she complained about mild abdominal pain though she had daily defecation. Despite encouraging ambulation, her compliance was low. Resection of the sigmoid colon and colostomy were performed after diagnosis with bowel perforation. However, the patient went into septic shock and died with multiorgan failure after the guardians issued a DNR (do not resuscitate) order. For preventing bowel perforation, increased uptake of dietary fiber and early ambulation postoperatively should be encouraged, after even hand surgeries.

  • Trichoblastic carcinoma usually occurs as a malignant transformation of the trichoblastoma, but is very rare. A 25-year-old man was admitted with trichoblastoma in the nuchal area with frequent recurrences since birth. The preoperative neck magnetic resonance image revealed lobulated soft tissue lesions involving superficial fascia and infiltrating into both proximal trapezius muscles. In our department, wide excision and reconstruction with a free anterolateral thigh flap were performed. Histological examination revealed skin adnexal carcinoma, originating from the hair follicles, consistent with trichoblastic carcinoma. There was no palpable mass 5 years postoperatively, and there was no recurrence on follow-up positron emission tomography-computed tomography. Trichoblastic carcinomas are rare and difficult to diagnose, but histopathological findings include atypical basaloid keratinocytes with crowded, hyperchromatic nuclei, and increased mitotic activity. The presence of hypercellular stroma is a criterion for distinguishing trichoblastic carcinoma from basal cell carcinoma. A rare giant trichoblastic carcinoma was reported, which was the biggest one in the literature.

  • There are various types of flap in head and neck reconstruction. We chose the appropriate flap considering the indication and patient's condition. In case of conventional flaps, its type is decided according to the reconstruction site. In other words, the types of considerable flaps are limited in a way. But, perforator flaps can reduce donor limitation and harvest flaps depending on the condition of the recipient. Therefore, the flap is very useful for the head and neck reconstruction needed for 2-dimensional or 3-dimensional reconstruction. We report the 29 cases of perforator-based flap including 8 cases of latissimus dorsi perforator free flap, 5 thoracodorsal perforator free flap, 4 anterolateral thigh perforator free flap, 3 peroneal osteocutaneous perforator free flap and 9 submental perforator island flap for the head and neck reconstruction. Free flaps include 2 cases of chimeric pattern, 7 controlled resurfacing pattern, 4 3-D pattern, 3 dermoadiposal pattern, 1 folded pattern and 3 osteocutaneous pattern. The flaps were successfully used for the head and neck reconstruction. But one patient died during a follow up period because of the recurrence of tumor. Various perforator flaps(island/free pattern) can be highly competitive to the conventional flaps in the head and neck reconstruction, considering a thin character for resurfacing, more flexible and versatile option, variable composition, long pedicle with donor structures saved, and less prominent donor morbidity.

  • Although uncommon, shark attacks can lead to devastating outcomes for victims. Surgeons also face unique challenges during operative management such as exsanguination, shock, specific injury patterns and infections. This case report presents the management of a 39-year-old previously healthy female attacked by a shark while on vacation in Mexico. The patient sustained severe injuries to her left arm and her left thigh. She was transferred to a Canadian institution after ambiguous operative management in Mexico and presented with no clear antibiotic coverage and a Volkman's contracture of the left upper extremity. In total, the patient underwent four washouts of wounds, two split-thickness skin grafts, one free anterolateral thigh flap, and one free transverse rectus abdominus myocutaneous flap for the reconstruction and salvage of the left lower extremity. This article highlights the specifics of this case and describes important points in managing these devastating injuries.

  • Background Single free flaps are a commonly used reconstructive method for multiple soft tissue defects in digits. We analyzed the flap size, division timing, and degree of necrosis in cases with various types of flap division. Methods We conducted a retrospective review of the medical charts of patients who had undergone single free flap reconstruction for multiple soft tissue defects across their digits from 2011 to 2020. The flap types included were the lateral arm free flap, venous forearm free flap, thenar free flap, hypothenar free flap, anterolateral thigh free flap, medial plantar free flap, and second toe pulp free flap. Flap size, anastomosed vessels, division timing, and occurrence of flap necrosis were retrospectively investigated and then analyzed using the t-test. Results In total, 75 patients were included in the analysis. The success rate of the free flaps was 97.3%. All flaps were successfully divided after at least 17 days, with a mean of 47.17 days (range, 17-243 days) for large flaps and 42.81 days (range, 20-130 days) for the medium and small flaps (P=0.596). The mean area of flap necrosis was 2.38% in the large flaps and 2.58% in the medium and small flaps (P=0.935). Severe necrosis of the divided flap developed in two patients who had undergone flap division at week 6 and week 34. Conclusions In cases where blood flow to the flap has been stable for more than 3 weeks, flap division can be safely attempted regardless of the flap size.
