INTRODUCTION@#Percutaneous transluminal angioplasty (PTA) is commonly used to treat patients with chronic limb-threatening ischaemia (CLTI). This study aimed to examine the mortality and functional outcomes of patients with CLTI who predominantly had diabetes mellitus in a multi-ethnic Asian population in Singapore.@*METHODS@#Patients with CLTI who underwent PTA between January 2015 and March 2017 at the Vascular Unit at Singapore General Hospital, Singapore, were studied. Primary outcome measures were 30-day unplanned readmission, two-year major lower extremity amputation (LEA), mortality rates, and ambulation status at one, six and 12 months.@*RESULTS@#A total of 221 procedures were performed on 207 patients, of whom 184 (88.9%) were diabetics. The one-, six- and 12-month mortality rate was 7.7%, 16.4% and 21.7%, respectively. The two-year LEA rate was 30.0%. At six and 12 months, only 96 (46.4%) and 93 (44.9%) patients were ambulant, respectively. Multivariate analysis revealed that preoperative ambulatory status, haemoglobin, Wound Ischaemia and foot Infection (WIfI) score, and end-stage renal failure (ESRF) were independent predictors of one-year ambulatory status. Predictors of mortality at one, six and 12 months were ESRF, preoperative albumin level, impaired functional status and employment status.@*CONCLUSION@#PTA for CLTI was associated with low one-year mortality and two-year LEA rates but did not significantly improve ambulation status. ESRF and hypoalbuminaemia were independent predictors of mortality. ESRF/CKD and WIfI score were independent predictors of loss of ambulation at six months and one year. We need better risk stratification for patients with CLTI to decide between initial revascularisation and an immediate LEA policy.

Shark attacks are rare unique pathological processes. Some of them represent devastating injuries with a high morbidity and significant mortality. Related published articles are limited. The increased human interaction within the environment of sharks is the cause of rising incidence of such attacks. This study reported a case of level 4 shark injuries (shark-induced trauma scale) in a 33-year-old male patient, who presented with an extensive injury of the right lower limb with the characteristic features of shark bite. At admission the patient was in a state of shock with profuse bleeding that was controlled by tourniquet. The patient was resuscitated according to the advanced trauma life support. Clinical examination showed hard signs of vascular injury with absent pedal pulse, associated neurological deficits and severance at the knee joint. Prompt vascular intervention after resuscitation was performed to manage the major vascular injuries, together with proper washout and debridement of all the necrotic tissues under strong antibiotic coverage to prevent infection. After that, the patient underwent sequenced plastic, orthopedic, and neurological interventions. Strict follow-up was conducted, which showed that the patient was saved and achieved a functioning limb. This study aims to highlight the management of level 4 shark injuries, which are considered serious and challenging with a high fatality rate and a great risk of amputation due to the associated major vascular injuries. Immediate well organized management plan is crucial. Prompt resuscitation and surgical intervention by a highly-skilled medical team are required to improve the chance of patient survival and limb salvage.

Introduction: One of the surgical treatment techniques used as an alternative to amputation is limb salvage surgery (LSS) with endoprothesis. Although the LSS can improve quality of life, causes a variety of functional deficiencies, and creates a need to integrate physical therapy rehabilitation into the team for LSS. Objective: To carry out a review on the physiotherapeutic interventions in the postoperative LSS in patients with proximal tibial osteosarcoma. Methods: Literature review, aimed at physiotherapeutic protocols in the rehabilitation of patients submitted to preservation surgery of limbs of proximal tibia. Results: Among the articles studied, three were selected for comparison of physiotherapeutic treatment protocols in the postoperative of preservation surgery of limbs of proximal tibia. Conclusion: We concluded that a greater incentive is needed in the development of research related to physiotherapeutic rehabilitation protocols in the LSS postoperative period in the proximal tibia, in order to obtain more treatment alternatives that aim to improve the quality of life and survival of these patients.

INTRODUCCIÓN: El trauma vascular es un evento de baja frecuencia, con alta morbimortalidad que afecta la población joven; requiere en general un manejo quirúrgico. Se asocia a complicaciones desde la reintervención quirúrgica hasta la amputación de la extremidad, influenciado por variables tanto asociadas al trauma como a la atención hospitalaria. OBJETIVO: Determinar los factores de riesgo relacionados con amputación, en pacientes con trauma arterial periférico (TAP), atendidos en un Hospital de III nivel Huila- Colombia entre 2014-2017. MATERIALES Y MÉTODOS: Estudio observacional, analítico de corte retrospectiva con pacientes mayores de 13 años con TAP. RESULTADOS: Se incluyeron 79 pacientes, con un 1,56% de las consultas en nuestro Servicio de Urgencia. 89% hombres, promedio de edad 28,5 años. La principal comorbilidad fue la farmacodependencia 8,8%. El MESS (mangled extremity severity) promedio fue de 5,27 puntos y un tiempo critico de isquemia de extremidad > a 6 horas en el 38%. El mayor compromiso fue de miembros superiores, secundario a heridas por arma cortopunzante. La lesión predominante fue la transección arterial. Las principales complicaciones posquirúrgicas fueron la trombosis del vaso (21,5%) y la amputación (13,9%). Factores de riesgo asociados a amputación fueron la edad > 20 años, estancia hospitalaria > 7 días, MESS > 7 puntos, que presentaran como complicación quirúrgica la trombosis arterial y que requirieran reintervención quirúrgica. CONCLUSIONES: El trauma arterial periférico es una patología con gran repercusión socioeconómica y secuelas funcionales. Es necesaria la atención oportuna con tratamiento de las variables relacionadas con mal pronóstico, con el fin de disminuir las tasas de morbimortalidad.

INTRODUCTION: Vascular trauma is a low frequency event, with high morbidity and mortality that affects the young population; In general, it requires surgical management. It is associated with complications from surgical reintervention to amputation of the limb, influenced by trauma associated variables such as hospital care. AIM: Determine risk factors related to amputation, in patients with peripheral arterial trauma (TAP), treated at a Hospital of III level Huila-Colombia between 2014-2017. MATERIALS AND METHOD: Observational, retrospective analytical study with patients older than 13 years with TAP. RESULTS: We included 79 patients with an incidence of 1.56%. 89% men, average age 28.5 years. The main comorbidity was 8.8% drug dependence. The MESS (Mangled extremity severity) average was of 5.27 points and a critical time of limb ischemia > to 6 hours in 38%. The greater commitment was of superior members, secondary to injuries by sharp weapon. The predominant lesion was arterial transection. The main postoperative complications were vessel thrombosis (21.5%) and amputation in 13.9%. Risk factors associated with amputation were determined by age > 20 years, hospital stay > 7 days, MESS > 7 points, and that they presented arterial thrombosis as a surgical complication and finally required surgical reoperation. CONCLUSIONS: Peripheral arterial trauma is a pathology with great socioeconomic impact and functional sequelae. It is necessary the timely attention with treatment of the variables related to poor prognosis, in order to decrease the morbidity and mortality rates.

Background: Extremity arterial injuries are an important cause of loss of life/limb after trauma. Early intervention is important for the good outcome. Objectives: The objective of this study is to review the pattern of presentation and study the factors that influences the outcome of extremity arterial injuries in our hospital. Patients and Methods: This is a retrospective study of all patients with injuries to the extremity arteries requiring surgical intervention from July 2007 to June 2015. Data obtained included biodata, ischemic time, arteries involved, surgical intervention, and outcomes and analyzed using SPSS version 22. Setting: Our hospital is the main referral hospital for vascular trauma serving four adjoining states in Nigeria and is linked to major cities by at least 3 Trunk-A federal roads. Subjects: The subjects are patients who were managed in our cardiovascular surgical unit for the study duration (July 2007­June 2015) who had extremity arterial injuries. Results: A total of 36 patients presenting with 40 arterial injuries in 37 limbs were studied. The mean age was 28.4 ± 10.3 years with male preponderance (88.9%). Gunshot injuries were the most common cause of arterial injuries (37.8%), followed by assault (27%). The mean time from injury to presentation for acute injuries was 20.4 h but 23 of the patients (63.8%) presented to the accident and emergency department within 12 h of injury. A limb salvage rate of 64.9% was achieved though ischemic times of ≥12 h were associated with poor outcomes. Conclusion: Prolonged ischemic time is associated with poor outcomes. Efforts should be put in place to reduce the limb ischemic times

PURPOSE: Mangled injury is defined as severe injury, including three or more tissues such as bones, nerves, vessels, muscles, and tendons in the upper or lower extremities. The choice of treatment results in different cosmetic and functional outcomes for mangled injury. In this study, we estimated patients' quality of life after treatment with the future intention of having patients make proper decisions at the time of injury. METHODS: Twenty patients were treated at Asan Medical Center from January, 2009 to November, 2011, and 11 patients were included who agreed with the questionnaire. We used 36-item short form health survey (SF-36) for estimating quality of life after treatments. RESULTS: Subjective satisfaction of cosmetic and functional aspects was higher in the reconstruction group than in the amputation group. However, in the estimation of specified satisfaction using SF-36, the amputation group was more satisfied than the reconstruction group. CONCLUSION: Among the many treatment considerations at the time of injury, expected cosmetic and functional outcomes were important parts determining the decision. In our study, the amputation group showed a better satisfaction level. This result could help patients make more appropriate decisions in the case of mangled injury.

Ameloblastoma in the tibia is rare. Limb reconstruction after tumor resection is challenging in terms of selection of the operative method. Here, we report a case of radical resection of an ameloblastoma in the mid-distal tibia combined with limb salvage using a three-dimensional (3D)-printed prosthesis replacement, with 1-year follow-up results. After receiving local institutional review board approval, a titanium alloy prosthesis was designed using a computer and manufactured with 3D-printing technology. During the operation, the stem of the prosthesis was inserted closely into the proximal tibial medullary cavity. Then, the metal ankle mortise and the talus were compacted closely. Radiographic results at 1-year follow up showed that the prosthesis was well placed, and no loosening was observed. The Musculoskeletal Tumor Society (MSTS) 93 functional score was 26 points, and the functional recovery percentage was 86.7%. Computer-assisted 3D-printing technology allowed for more volume and structural compatibility of the prosthesis, thereby ensuring a smooth operation and initial prosthetic stabilization. During the follow up, the presence of bone ingrowths on the porous surface of some segments of the prosthesis suggested good outcomes for long-term biological integration between the prosthesis and host bone.

PURPOSE: The clinical characteristics and results of femoropopliteal artery injury (FPAI) remain unclear. In this study, we evaluated the outcomes and risk factors of limb loss in patients treated for FPAI. MATERIALS AND METHODS: We retrospectively reviewed data from a database of patients who underwent revascularization for an FPAI at a single institution between January 2013 and December 2017. We reviewed and analyzed the characteristics, postoperative results, and factors that influence amputation rates. RESULTS: Twenty-four femoropopliteal arterial reconstructions in 24 patients were included in this study. Among the patients were 20 (83.3%) male with a first-quartile age of 28 years and a third-quartile age of 45 years (range, 15–68 years). The mean injury severity score (ISS) was 16 (range, 4–55), and 5 patients (20.8%) had ISSs of >20 points. The mean mangled extremity severity score (MESS) was 3.8 (range, 1–11), and 8 patients (33.3%) had MESSs of >5 points. In terms of arterial reconstruction methods, autogenous saphenous vein grafting, vein patching, and primary closure were performed in 9 patients (37.5%), 4 patients (16.7%), and 11 patients (45.8%), respectively. Despite arterial reconstruction, 5 patients (20.8%) underwent above-knee amputation. ISSs of >20, MESSs of >7, and orthopedic fixation were statistically significant factors associated with amputation. CONCLUSION: In cases of FPAI with ISSs of >20, MESSs of >7, and orthopedic fixation, amputations should be considered. We were also careful to attempt limb salvage in such cases.

After diagnosis of peripheral artery disease in diabetic patients, revascularization can be considered in those who are not improved after guideline-directed medical therapy. Recently, more aggressive approaches with interventional treatment have been recommended. Before revascularization therapy, it is important to differentiate patients with claudication or critical limb ischemia, and the final goal and treatment modality of interventional treatments should be based on clinical diagnosis. For patients with claudication, the goal of revascularization is improvement of functional capacity or quality of life; however, in more severe forms of critical limb ischemia, the purpose of revascularization is limb salvage and ultimately saving patient's life. With improvement of vascular interventions, interventional treatment for peripheral artery disease is preferred, although surgical treatment might show better results than intervention in some cases.

PURPOSE: Tumor infiltration around the knee joint or skip metastasis, repeated infection sequelae after tumor prosthesis implantation, regional recurrence, and mechanical failure of the megaprosthesis might require combined distal femur and proximal tibia replacement (CFTR). Among the aforementioned situations, there are few reports on the indication, complications, and implant survival of CFTR in temporarily arthrodesed patients who had a massive bony defect on either side of the knee joint to control infection. MATERIALS AND METHODS: Thirty-four CFTR patients were reviewed retrospectively and 13 temporary arthrodesed cases switched to CFTR were extracted. All 13 cases had undergone a massive bony resection on either side of the knee joint and temporary arthrodesis state to control the repeated infection. This paper describes the diagnosis, tumor location, number of operations until CFTR, duration from the index operation to CFTR, survival of CFTR, complications, and Musculoskeletal Tumor Society (MSTS) score. RESULTS: According to Kaplan-Meier plot, the 5- and 10-year survival of CFTR was 69.0%±12.8%, 46.0%±20.7%, respectively. Six (46.2%) of the 13 cases had major complications. Three cases underwent removal of the prosthesis and were converted to arthrodesis due to infection. Two cases underwent partial change of the implant due to loosening and periprosthetic fracture. The remaining case with a deep infection was resolved after extensive debridement. At the final follow-up, the average MSTS score of 10 cases with CFTR was 24.6 (21–27). In contrast, the MSTS score of 3 arthrodesis cases with failed CFTR was 12.3 (12–13). The average range of motion of the 10 CFTR cases was 67° (0°–100°). The mean extension lag of 10 cases was 48° (20°–80°). CONCLUSION: Although the complication rates is substantial, conversion of an arthrodesed knee to a mobile joint using CFTR in a patient who had a massive bony defect on either side of the knee joint to control infection should be considered. The patient's functional outcome was different from the arthrodesed one. For successful conversion to a mobile joint, thorough the eradication of scar tissue and creating sufficient space for the tumor prosthesis to flex the knee joint up to 60° to 70° without soft tissue tension.

Las úlceras del pie diabético son el principal factor de riesgo para las amputaciones no traumáticas en personas con diabetes. El éxito de la intervención requiere un completo entendimiento de la patogénesis y una implementación oportuna y estandarizada de un tratamiento efectivo. Es necesario un enfoque multidisciplinario para inicialmente controlar y tratar múltiples factores causantes de la ulceración severa del pie diabético. El desbridamiento, control de la infección y revascularización son pasos clave para la estabilización de la herida y su preparación para una reconstrucción exitosa. La microcirugía y supermicrocirugía permite proporcionar un tejido bien vascularizado para controlar la infección, un contorno adecuado para el calzado, durabilidad y anclaje sólido para resistir las fuerzas de cizallamiento durante la marcha. De esta manera, se puede lograr el salvataje de la extremidad, mejorando la calidad de vida y aumentando la sobrevida.

Diabetic foot ulcers are the main risk factor for non-traumatic amputations in people with diabetes. A succesful intervention requires a thorough understanding of the pathogenesis and a timely and standardized implementation of an effective treatment. A multidisciplinary approach is needed to initially control and treat multiple factors that cause severe diabetic foot ulceration. Debridement, infection control, and revascularization are key steps in wound stabilization and preparation for successful reconstruction. Microsurgery and supermicrosurgery provide a well-vascularized tissue to control infection, an adequate shoe contour, durability and solid anchorage to resist shearing forces during gait. In this way, the salvage of the limb can be achieved, improving the quality of life and increasing the survival rate.

ABSTRACT Peri-articular giant cell tumours present a unique challenge to the orthopaedic surgeon due to their locally aggressive nature. Native joint-preserving options confer less morbidity in comparison to radical excision and reconstruction; however, recurrence rates tend to be higher. The use of polymethyl methacryllate (PMMA) decreases the recurrence rate, but it has potentially devastating effects on the articular cartilage. To safeguard against this, the use of an insulating layer between the PMMA and the articular cartilage may be utilized with the goal of protecting the latter and is referred to as the Sandwich technique.

RESUMEN Los tumores de células gigantes periarticulares representan un desafío único al cirujano ortopédico debido a su naturaleza localmente agresiva. Las opciones de conservación de las articulaciones nativas confieren menos morbilidad en comparación con la supresión y reconstrucción radicales. Sin embargo, las tasas de recurrencia tienden a ser más altas. El uso de polimetilmetacrilato (PMMA) disminuye la tasa de recurrencia, pero tiene efectos potencialmente devastadores sobre el cartílago articular. Para protegerlo, el uso de una capa aislante entre el PMMA y el cartílago articular puede ser utilizarse con el objetivo de proteger este último, lo que se conoce como la técnica del sándwich.

Orthopaedics is an area where 3-dimensional (3D) printing technology is most likely to be utilized because it has been used to treat a range of diseases of the whole body. For arthritis, spinal diseases, trauma, deformities, and tumors, 3D printing can be used in the form of anatomical models, surgical guides, metal implants, bio-ceramic body reconstruction, and orthosis. In particular, in orthopaedic oncology, patients have a wide variety of tumor locations, but limited options for the limb salvage surgery have resulted in many complications. Currently, 3D printing personalized implants can be fabricated easily in a short time, and it is anticipated that all bone tumors in various surgical sites will be reconstructed properly. An improvement of 3D printing technology in the healthcare field requires close cooperation with many professionals in the design, printing, and validation processes. The government, which has determined that it can promote the development of 3D printing-related industries in other fields by leading the use of 3D printing in the medical field, is also actively supporting with an emphasis on promotion rather than regulation. In this review, the experience of using 3D printing technology for bone tumor surgery was shared, expecting orthopaedic surgeons to lead 3D printing in the medical field.

BACKGROUND: Limb salvage surgery with vascular reconstruction is currently considered as the standard treatment for extremity soft tissue sarcoma (STS), showing equivalent oncologic outcome compared with amputation. In this retrospective study, the surgical and functional outcomes after arterial or venous reconstruction in limb salvage surgery for STS were analyzed. METHODS: Consecutive patients who underwent vascular resection and reconstruction as part of limb salvage surgery for extremity STS from July 2009 to June 2015 were included in this study. Incidence of surgical complication, graft patency, and patients' functional outcome were reviewed. RESULTS: During the study period, 14 arteries and 13 veins were reconstructed in 17 patients (artery only in 4, vein only in 3, artery and vein in 10). Autologous great saphenous vein (GSV) was the most commonly used vascular conduit in both arterial and venous reconstruction (78.6% and 77.0%). The patency of synthetic graft was significantly lower than that of the autologous vein conduit (log rank test, P = 0.001). Among 15 patients with tumors in lower extremity, 13 were ambulatory after limb salvage surgery. During median follow up of 23.3 months (interquartile range 39.9 months), 2 patients (11.7%) needed amputation of the initially salvaged limb due to local recurrence. CONCLUSION: Limb salvage surgery of soft tissue tumor combined with vascular reconstruction showed favorable functional outcome with good local control. Autologous vein conduit is preferred over synthetic graft both in arterial and venous reconstruction.

OBJECTIVE: To retrospectively evaluate the impact of pedal arch quality on tissue loss and time to healing in diabetic patients with foot wounds undergoing infrainguinal endovascular revascularization. MATERIALS AND METHODS: Between January 2014 and June 2015, 137 consecutive diabetic patients with foot wounds underwent infrainguinal endovascular revascularization (femoro-popliteal or below-the-knee, arteries). Postprocedural angiography of the foot was used to divide the patients into the following three groups according to the pedal arch status: complete pedal arch (CPA), incomplete pedal arch (IPA), and absent pedal arch (APA). Time to healing and estimated 1-year outcomes in terms of freedom from minor amputation, limb salvage, and survival were evaluated and compared among the three groups. RESULTS: Postprocedural angiography showed the presence of a CPA in 42 patients (30.7%), IPA in 60 patients (43.8%), and APA in 35 patients (25.5%). Healing within 3 months from the procedure was achieved in 21 patients with CPA (50%), 17 patients with IPA (28.3%), and in 7 patients with APA (20%) (p = 0.01). There was a significant difference in terms of 1-year freedom from minor amputation among the three groups (CPA 84.1% vs. IPA 82.4% vs. APA 48.9%, p = 0.001). Estimated 1-year limb salvage was significantly better in patients with CPA (CPA 100% vs. IPA 93.8% vs. APA 70.1%, p < 0.001). Estimated 1-year survival was significantly better in patients with CPA (CPA 90% vs. IPA 80.8% vs. APA 62.7%, p = 0.004). CONCLUSION: Pedal arch status has a positive impact on time to healing, limb salvage, and survival in diabetic patients with foot wounds undergoing infrainguinal endovascular revascularization.

ABSTRACT OBJECTIVE: The objective of this study is to evaluate the efficacy of vascular reconstructive surgery after resection of bone and soft tissue tumors in extremities and the risk of progression to amputation. METHODS: This is a retrospective, observational data collection from medical records of patients who underwent resection of bone and soft tissue tumors in the period of 2002-2015. Thirteen patients met the inclusion criteria, which evaluated the correlations between certain factors (gender, tumor type, location, reconstruction, revascularization and patency, infection) with amputation in the postoperative period. RESULTS: In this study, of the 13 patients undergoing reconstruction, five (38.46%) evolved to amputation. All patients who progressed to amputation had the following in common: presence of bone sarcoma (p = 0.005), having undergone reconstruction with an orthopedic prosthesis (p = 0.005), lack of vascular patency in the revascularization site in the postoperative period (p = 0.032), and surgical site infection (p = 0.001). None of the patients with soft tissue sarcoma underwent amputation, and the only patient with bone sarcoma who did not undergo amputation had no infection and maintained vascular patency of the graft. CONCLUSION: The occurrence of infection appears to be one of the main risk factors for failure of revascularization, especially in cases of bone sarcoma in which vascular reconstruction is performed with placement of a non-conventional joint prosthesis.

RESUMO OBJETIVO: O objetivo deste estudo é avaliar a eficácia da cirurgia de reconstrução vascular após ressecção de tumores ósseos e tecidos moles em extremidades e o risco de evolução para amputação. MÉTODOS: Estudo retrospectivo, observacional, de coleta de dados em prontuário médico de pacientes submetidos a ressecção de tumores ósseos e de tecidos moles de 2002 a 2015; 13 pacientes preencheram o critério de inclusão, foram avaliadas as correlações de determinados fatores (gênero, tipo de tumor, localização, reconstrução, revascularização e patência, infecção) com amputação no pós-operatório. RESULTADOS: No presente estudo, dos 13 pacientes submetidos à reconstrução, cinco (38,46%) evoluíram com amputação. Todos os pacientes que evoluíram com amputação tinham em comum o fato de ser portadores de sarcoma ósseo (p = 0,005), ter sido submetidos a reconstrução com prótese ortopédica (p = 0,005) e não apresentar patência vascular no local da revascularização no período pós-operatório (p = 0,032), além de apresentar infecção no local da cirurgia (p = 0,001). Nenhum dos pacientes portadores de sarcoma de partes moles foi submetido à amputação e o único paciente do grupo com sarcoma ósseo que não sofreu amputação não apresentava infecção e mantinha patência vascular no enxerto. CONCLUSÃO: A ocorrência de infecção parece ser um dos principais fatores de risco para a falência da revascularização, especialmente nos casos de sarcoma ósseo em que a reconstrução vascular é feita juntamente com colocação de próteses articulares não convencionais.

Abstract: The giant cell tumor of bone is one of the most controversial neoplasms due to growth patterns that may present. The case reported shows a very aggressive tumor in a classic location, but key to hand function. Rather than treat with radical surgery, was planned and performed a wide resection with an ulnar-carpus arthrodesis and microsurgical reconstruction of the defect throught an anterolateral thigh flap. The multidisciplinary approach of bone neoplasms produce a positive impact on patients.

Resumen: El tumor óseo de células gigantes es una de las neoplasias más controversiales debido a los patrones de crecimiento que pueden presentar. El caso reportado muestra un tumor muy agresivo en una localización clásica, pero clave para la función de la mano. En lugar de tratarla mediante cirugía radical, se planeó y realizó una resección amplia con artrodesis cúbito-carpiana y la reconstrucción microquirúrgica del defecto mediante un colgajo anterolateral de muslo. El abordaje multidisciplinario de las neoplasias óseas repercute positivamente en los pacientes.

PURPOSE: Femorofemoral crossover bypass (FCB) is a good procedure for patients with unilateral iliac artery disease. There are many articles about the results of FCB, but most of them were limited to 5 years follow-up. The purpose of our study was to analysis the results of FCB with a 10-year follow-up period. MATERIALS AND METHODS: Between January 1995 and December 2010, 133 patients were operated in Samsung Medical Center (median follow-up: 58.8 months). We retrospectively analysed patient characteristics, the preoperative treatment, the operative procedure, and material used. RESULTS: The indications for FCB were claudication in 110 and critical limb ischemia in 23 patients. Three patients were died due to myocardiac infarction, intracranial hemorrhage, and acute respiratory failure within 30 days after surgery. The one-year primary and secondary patency rates were 89% and 97%, the 5-year primary and secondary patency rates were 70% and 85%, and the 10-year primary and secondary patency rates were 31% and 67%. The 5-year and 10-year limb salvage rates were 97% and 95%, respectively. CONCLUSION: Our long term analysis suggests that FCB might be a valuable alternative treatment modality in patients with unilateral iliac artery disease.

PURPOSE: Use of a composite graft combining a polytetrafluoroethylene graft with an autogenous vein is an option for limb salvage in the absence of an adequate single segment vein graft. We aimed to investigate the results of infrainguinal bypass with a composite graft. MATERIALS AND METHODS: We retrospectively reviewed 11 infrainguinal arterial bypasses on 11 limbs which underwent surgery from March 2012 to November 2016. RESULTS: Critical limb ischemia was common (63.6%) indication of bypass surgery and most (90.9%) of the patients had history of failed previous treatment including endovascular treatment (36.4%) and bypass surgery (72.7%). At the 2 years after graft implantations, primary patency and amputation-free survival of below-knee bypasses using composite graft were 73% and 76%, respectively. CONCLUSION: Infrainguinal arterial bypasses with composite graft had an acceptable patency. In patients without other alternative conduits for revascularization, bypass with a composite graft can be an option.

BACKGROUND: We conducted this study to identify factors that may prolong the length of the hospital stay (LHS) in patients with diabetic foot (DF) in a single-institution setting. METHODS: In this single-center retrospective study, we evaluated a total of 164 patients with DF, and conducted an intergroup comparison of their baseline demographic and clinical characteristics, including sex, age, duration of diabetes, smoking status, body mass index, underlying comorbidities (e.g., hypertension or diabetic nephropathy), wound characteristics, type of surgery, the total medical cost, white blood cell (WBC) count, C-reactive protein (CRP) levels, erythrocyte sedimentation rate, and albumin, protein, glycated hemoglobin, and 7-day mean blood glucose (BG) levels. RESULTS: Pearson correlation analysis showed that an LHS of >5 weeks had a significant positive correlation with the severity of the wound (r=0.647), WBC count (r=0.571), CRP levels (r=0.390), DN (r=0.020), and 7-day mean BG levels (r=0.120) (P 5 weeks had a significant positive correlation with the severity of the wound (odds ratio [OR]=3.297; 95% confidence interval [CI], 1.324–10.483; P=0.020), WBC count (OR=1.423; 95% CI, 0.046–0.356; P=0.000), CRP levels (OR=1.079; 95% CI, 1.015–1.147; P=0.014), albumin levels (OR=0.263; 95% CI, 0.113–3.673; P=0.007), and 7-day mean BG levels (OR=1.018; 95% CI, 1.001–1.035; P=0.020). CONCLUSIONS: Surgeons should consider the factors associated with a prolonged LHS in the early management of patients with DF. Moreover, this should also be accompanied by a multidisciplinary approach to reducing the LHS.
