Transversely‐inset great toe hemi‐pulp flap transfer for the reconstruction of a thumb‐tip defect

Thumb‐tip defect is a common traumatic disease, and replantation of an amputated thumb‐tip is the first choice of treatment when available. When an amputee is not available, local flaps such as volar advancement flap are used for reconstruction. However, it is difficult to cover whole defect area by a local flap when a defect is relatively large. In this report, we present a case of the use of a free great toe hemi‐pulp flap transfer to reconstruct a thumb‐tip defect. A 69‐year‐old right‐handed male suffered from the right thumb‐tip crush amputation in Tamai Zone 2. The distal phalanx and the nail matrix were preserved, and the defect size was 5 cm × 4 cm. The thumb‐tip was reconstructed with a free great toe hemi‐pulp flap under local anesthesia. The flap included extended subcutaneous adiposal tissue (skin size 4.5 cm × 3 cm; fat size 4.5 cm × 5.5 cm) to reconstruct the nail bed, and was transversely inset at the recipient site to cover the whole area of the defect. The donor site could be primarily closed without skin grafting. At postoperative 6 months, the patient was satisfied with good results of the reconstructed thumb‐tip and the donor site. Transversely‐inset great toe hemi‐pulp flap may be useful to reconstruct a thumb‐tip defect, which allows relatively wide defect reconstruction. © 2014 Wiley Periodicals, Inc.

Free latissimus dorsi flap with long venous grafts for closure of a soft tissue defect of the spine in a patient with Noonan's syndrome: A case report

A 23‐year‐old male patient was operated for a soft tissue defect of the spine using a free musculocutaneous latissimus dorsi flap with two 21‐cm long venous grafts connecting the flap to its vascular supply at the thoracodorsal vessels. This young patient suffered from Noonan's Syndrome that is a complex hereditary malformation syndrome with clinical features often leading to spinal deformities and gibbus development. The defect originated from a former internal vertebral fixation that was necessary for erective correction of such a spinal deformity. After perforation of the introduced material and debridement the defect was 4 × 8 cm in size, which was successfully closed by the free latissimus dorsi transfer. However, two venous grafts were necessary because the extension of the pedicled muscle was not sufficient to reach the defect. This is the first case in literature where a free flap was used with two venous grafts to close a soft tissue defect of the spine in the special case of a vertebral deformity based on a Noonan's Syndrome. © 2009 Wiley‐Liss, Inc.

Fibula osteo‐adipofascial flap for reconstruction of a cervical spine and posterior pharyngeal wall defect

When reconstructing combined defects of the cervical spine and the posterior pharyngeal wall the goals are bone stability along with continuity of the aerodigestive tract. We present a case of a patient with a cervical spine defect, including C1 to C3, associated with a posterior pharyngeal wall defect after excision of a chordoma and postoperative radiotherapy. The situation was successfully solved with a free fibula osteo‐adipofascial flap. The reconstruction with a fibula osteo‐adipofascial flap provided several benefits in comparison with a fibula osteo‐cutaneous flap in our case, including an easier insetting of the soft tissue component at the pharyngeal level and less bulkiness of the flap allowing our patient to resume normal deglutition. © 2013 Wiley Periodicals, Inc.

Successful management of osteoradionecrotic precoccygeal defect with the free latissimus dorsi muscle flap: Case report and literature review

Perineal wound complications following abdominoperineal resection (APR) are still frequent and most troublesome complications. We report the case of a 79‐year‐old male found to have the huge precoccygeal defect with infection after APR for rectal carcinoma. Before surgery, the patient received a complete course of chemoradiation therapy to treat for downgrade staging of the rectal malignancy. Extensive debridement of the perianal wound was performed for three times, followed by perianal reconstruction and packing and augmentation of the precoccygeal dead space with free latissimus dorsi (LD) muscle flap. Although persisted wound infection was still observed after reconstruction, the patient still led a good result after one time of further debridement and split‐thickness skin graft. We selected free LD muscle flap to fill and seal off the large pelvic dead space without the needs to change the jackknife position of the patient after debridement. To the best of our knowledge, this is the first case reported in the literature with the radiation‐associated perianal wound infection after APR reconstructed successfully by free LD muscle flap. © 2011 Wiley‐Liss, Inc.

Reconstruction of a full‐thickness,complex nasal defect that includes the nasal septum using a free,thin superficial inferior epigastric artery flap

Complex nasal defects present a surgical challenge, particularly in cases with a full‐thickness defect that extends into the nasal septum. Although the superficial inferior epigastric artery (SIEA) flap has been widely used as a bulky flap for soft tissue augmentation, reports on its use as a thin flap are limited. We present a case of complex nasal defect reconstruction using a free, thin SIEA flap. A 65‐year‐old man with a recurrent malignant peripheral nerve sheath tumor around the left nose and cheek underwent wide tumor resection, leaving a full‐thickness nasal defect that included portions of the nasal septum, nasal bone, and maxilla. A free, thin SIEA flap was elevated and primarily thinned by microdissecting the pedicle distally. The flap was then folded and inset to close the nasal septum and skin. The flap survived completely and complete closure of the nasal septum was observed. As the SIEA runs toward superficial layers as it is traced distally, primary thinning of the flap is possible. We believe that this method may represent an alternative to the superficial circumflex iliac artery perforator flap in cases in which the superficial circumflex iliac artery system is hypoplastic. © 2014 Wiley Periodicals, Inc.

Sliding free transverse rectus abdominis myocutaneous flap for closure of a massive abdominal wall defect: A case report

Despite considerable advances in reconstructive surgery, massive abdominal wall defects continue to pose a significant surgical challenge. We report the case of a 72‐year‐old morbidly obese female patient with Clostridium septicum‐related gas gangrene of the abdominal wall. After multidisciplinary treatment and multiple extensive debridements, a massive full‐thickness defect (40 cm × 35 cm) of the right abdominal wall was present. The abdominal contents were covered with a resorbable mesh to prevent evisceration. Finally, the composite defect was successfully reconstructed through a contralateral extended free transverse rectus abdominis myocutaneus (TRAM) flap (50 cm × 38 cm). An arterio‐venous loop to the superficial femoral vessels using the great saphenous vein was necessary to allow the flap to reach the defect. Postoperatively, a minor wound healing disorder of the flap was successfully treated with split skin grafting. Six month after surgery, the patient presented with a completely healed flap coverage area and a small abdominal hernia without the need of further surgical revision. This case illustrates the use of a sliding free TRAM flap for closure of a massive abdominal wall defect.

Endoscopic transcervical anterior release and posterior fixation in the treatment of irreducible vertical atlantoaxial dislocation

Vertical atlantoaxial dislocation is a type of atlantoaxial instability with upper cervical spinal cord compression. The transoral ondontoid resection with posterior fixation is the gold standard for ventral decompression. Results are satisfying though surgery can be challenging due to its invasiveness. The endoscopic transcervical anterior release could provide sufficient ventral decompression with less collateral damage. In the illustrative case, anatomic reduction was achieved with significant improvement in neurological function and radiographic parameters. Endoscopic transcervical anterior release and posterior fixation appears to be a viable and interesting alternative for the treatment of vertical atlantoaxial dislocation in properly selected individuals, and its implementation could significantly reduce the post-surgical complications.

Use of a 72‐cm‐long extended bilateral deep inferior epigastric artery perforator free flap for reconstruction of a lower leg with no suitable recipient vessel around the injury zone: A case report

In free‐flap reconstruction of the lower extremity, due either to trauma or pre‐existing vascular disease, healthy vessels may not be readily available in the proximity of the defect. A variety of options including a cross‐leg free flap, vein grafts, arteriovenous loops, and “bridging” flaps have been used to address the issue. The purpose of this report is to present a case in which a 72‐cm long extended bilateral deep inferior epigastric artery perforator (DIEP) free flap was used for coverage of a 20 × 25 cm soft tissue defect of the lower leg following a Gustilo grade IIIC fracture in a 29‐year‐old man. Because usable recipient vessels were far from the zone of injury, and to avoid complications accompanying long vein grafts, a long flap was necessary. The exposed tibia required coverage with a free flap, but peripheral portions of the defect with exposed muscles could be covered with a skin graft. Thus, a 72 × 12 cm flap was chosen. The flap was based on both bilateral DIEPs and on the superficial circumflex iliac artery (SCIA). The flap survived completely with no complications. After one debulking surgery, the flap and the donor site showed pleasing cosmesis, and the patient could walk without crutches at 18 months after the first surgery. In cases where no healthy recipient vessels can be found close to the defect, we believe that the use of an extended bilateral DIEP flap may be a feasible option which shortens or precludes vein grafts with no additional flap donor sites.     

Free flap reconstruction of oral composite defect complicated by intraoperative cardiac arrest: A case report

We report the case of intraoperative cardiac arrest of a patient undergoing free tissue harvest for an oral composite defect and subsequent completion of reconstruction with simultaneous double flaps. A 54‐year‐old man with advanced carcinoma of the tongue underwent near‐total glossectomy, segmental mandiblectomy, and bilateral neck dissections. We planned a fasciocutaneous anterolateral thigh flap to reconstruct the glossectomy defect, and a fibula osteocutaneous flap for the mandible defect. After the fibula flap harvest, the patient suffered a cardiac arrest. After a 4‐min code, the patient regained a sinus rhythm and became hemodynamically stable. We completed the cancer resection and banked the pedicled, osteotomized fibula flap in the lower extremity. We took the patient back to the operating room on postoperative day number 5 for successful reconstruction with simultaneous fibula and ALF flaps. The microvascular surgeon must always be poised to rapidly address intraoperative complications that may critically compromise the success of the free flap or, more seriously, jeopardize the patient's life. © 2012 Wiley Periodicals, Inc.

Transplantation of a latissimus dorsi flap after nearly 6 hr of extracorporal perfusion: A case report

Prolonged ischemia of tissues inevitably leads to their necrosis. This is especially relevant in the case of transplantation or replantation. In such situations, reperfusion in a timely manner might not be possible due to transportation times or other unforeseen complications. Therefore, a readily available and simple method to oxygenate the tissue and thus widen the time frame to reperfusion seems desirable. Here, we present the case of extracorporal perfusion of a latissimus dorsi (LD) flap that was successfully transplanted after nearly 6 hr of ischemia. A 41‐year‐old patient suffered multiple injuries including complete severance of the popliteal artery requiring emergency bypass. After stabilization of the patient and subsequent debridement, a LD flap was performed for soft tissue coverage. However, there was an acute occlusion of the bypass during flap inset. To salvage the free flap, a one‐way extracorporal perfusion of the flap with heparinized isotonic saline solution was performed for a total of 5 hr and 47 min. The flap survived with minimal tip necrosis. This case report describes the application of a simple extracorporal perfusion technique for salvage of a free flap over a prolonged ischemia time and discusses the relevant literature. Due to its ease and quickness of application as well as ubiquitous availability, it might serve as a valuable tool in cases of acute problems with the recipient vessels or other incidents where several hours of ischemia time are to be anticipated.     

Reverse Sural Flap with Bifocal Ilizarov Technique for Tibial Osteomyelitis with Bone and Soft Tissue Defects

Tibial osteomyelitis, in association with bone loss and a soft tissue defect, poses a significant reconstructive challenge, especially in high-risk patients. We describe a case of methicillin-resistant Staphylococcus aureus tibial osteomyelitis with intercalary bone loss successfully managed with bifocal Ilizarov compression osteogenesis at the bone resection site and proximal distraction osteogenesis, accompanied by a reverse sural fasciocutaneous flap performed with a delayed technique. When free tissue transfer is not a reconstructive option owing to medical comorbidities or patient refusal, the reverse sural flap combined with bifocal Ilizarov compression and distraction osteogenesis can provide a reconstructive option to achieve limb salvage for these challenging cases.     

Transnasal endoscopic repair of cerebrospinal fluid rhinorrhoea

The complications associated with the employment of neurosurgical techniques for the management of cerebrospinal fluid rhinorrhoea has led to the development of extracranial approaches. The nasal endoscope can be used to improve visualisation of the site of the leak and to facilitate free graft or septal flap placement. This ensures a high rate of dural defect healing with minimal morbidity. This study describes four cases with CSF fistulas that were repaired endoscopically and the specific surgical techniques that were used. The authors believe that, in carefully selected cases, transnasal endoscopic management of CSF leaks can be the initial surgical treatment of choice.

Flow‐through fibula flap using soleus branch as distal runoff: A case report

The flow‐through fibula flap utilizing the soleus branch as a distal runoff has not yet been reported. We herein present a patient with left tibial adamantimoma in whom wide resection of the tumor resulted in a segmental tibial defect 22 cm in length. The defect was successfully reconstructed with a flow‐through free fibula osteocutaneous flap using the soleus branch of the peroneal artery as a distal runoff. The short T‐segment of the peroneal artery was interposed to the transected posterior tibial artery. The soleus branch has a constant anatomy and a larger diameter than the distal stump of the peroneal artery. Short interposed flow‐through anastomosis to the major vessels is much easier and more reliable than the conventional methods. We believe that our method represents a versatile option for vascularized fibula bone grafting for extremity reconstruction. © 2012 Wiley Periodicals, Inc. Microsurgery, 2013     

Reconstruction of an upper posterior thigh extensive defect with a free split‐anterolateral thigh (s‐ALT) flap by perforator‐to‐perforator anastomosis: A case report

The anterolateral thigh (ALT) flap is one of the most commonly used flap worldwide in reconstructive surgery, as both free flap and pedicled local flap. Here, we report the use of a free split anterolateral thigh (s‐ALT) flap for reconstruction of a 14 cm × 16 cm soft tissue defect of the left upper posterior thigh region due to sarcoma resection in a patient. The ALT flap was harvested based on two musculocutaneous perforators from the right thigh and anastomosed to the contralateral descending branch of the lateral circumflex femoral artery (LCFA) in perforator‐to‐perforator manner, in order to gain more pedicle length and being able to cover the posterior thigh defect. The post‐operative course was uneventful and the patient was discharged at 1 week post‐operative. Eleven months after the operation, the aesthetic outcome was satisfactory with no functional deficit. Even though it requires technical skills and experience in perforator dissection, we believe that the s‐ALT flap anstomosed to the contralateral LCFA in perforator to perforator fashion, may be a good solution in case of such a difficultly located extensive defect of the posterior thigh.     

A totally laparoscopic peritoneal free flap for reconstruction of hand

Management of defects on the hand and foot with exposed tendons remains a major challenge for plastic surgeons. Here, we present a case of hand reconstruction with a totally laparoscopic peritoneal flap. The anterior rectus sheath was preserved in situ. The peritoneal free flap supplied by peritoneal branches of the deep inferior epigastric artery was retrieved by laparoscopy to cover the soft tissue defect of the hand. The defect of the dorsal hand was 17 cm * 12 cm. The peritoneal flap measuring 22 cm * 15 cm survived completely without any complications. A following split-thickness skin graft offered the successful wound closure. Motor and sensory function improved gradually within the first year follow-up. The totally laparoscopic peritoneal free flap is a good choice for reconstruction of the soft tissue defects accompanied by exposed tendons on the hand and foot.     

Calcaneal reconstruction with free fibular osteocutaneous flap

Due to the role of the calcaneus in weight bearing, soft tissue coverage along with proper reduction of the fracture is the treatment following open calcaneal injury. Intra-articular calcaneal fractures present a very difficult management problem, as the lack of soft tissue and the intricate vascularity in this area pose a risk of complications. Coverage with local and free muscle flaps following excision of infected structures is a common approach for the treatment of chronic osteomyelitis. However, it is unknown which type of flap is optimal for the treatment of lateral foot wounds, especially when complicated by calcaneal osteomyelitis. A patient presented with an open wound over the lateral aspect of the heel with exposed hardware and chronic osteomyelitis of the calcaneus. Following multiple debridements, an ipsilateral osteocutaneous free fibular flap was transferred to the bony defect. Weight bearing was initiated at 2 months postoperatively, and he now ambulates with a normal gait, has normal plantar sensation, and has no difficulty maneuvering stairs. The patient has done well postoperatively and has recovered full range of motion and complete mobility. In this case report, an osteocutaneous free flap provided an excellent outcome for an active patient with a very complex and complicated condition.
