Introducción: Los aneurismas de aorta abdominal resultan dilataciones arteriales a dicho nivel. Su ruptura constituye uno de los principales riesgos y provoca la muerte del paciente, de ahí la importancia de tratarlos a tiempo. Las opciones actuales de tratamiento son la cirugía abierta y la reparación aneurismática endovascular; esta última representa la primera línea de tratamiento, por constituir una técnica mínimamente invasiva con bajas tasas de morbilidad y mortalidad. Objetivo: Evaluar el tratamiento endovascular del aneurisma de la aorta abdominal con endoprótesis percutáneas en pacientes cubanos. Métodos: Entre enero y abril de 2018 se realizó un estudio prospectivo, descriptivo y cualitativo en 6 pacientes del sexo masculino con aneurisma de aorta abdominal, seleccionados aleatoriamente, que cumplieron los criterios de uso de endoprótesis vasculares y estuvieron de acuerdo con realizar el proceder. Se colocaron 6 dispositivos en una sala de angiografía, y se utilizó en los pacientes anestesia general y guía fluoroscópica. Resultados: De forma satisfactoria fue posible el tratamiento endovascular por vía percutánea de los 6 pacientes seleccionados; solo 1 presentó una complicación menor y fue dado de alta a las 72 horas y el resto fue egresado en menos de 24 horas. Se logró implementar por vez primera en el país el sistema de cierre percutáneo Proglide sin complicaciones. Conclusiones: El tratamiento endovascular por vía percutánea de aneurismas de aorta abdominal con endoprótesis vasculares es una alternativa eficaz para la cirugía convencional en pacientes que cumplen los criterios de uso del dispositivo(AU)

Introduction: Abdominal aortic aneurysms are arterial dilations in that level. Their rupture is one of the main risks and it causes death in patients; that is why the importance of treating them early. Among the current treatment options are open surgery and endovascular aneurismal reparation, being the last one in the first line of treatment since it is a minimal invasive technique with low rates of morbidity and mortality. Objective: To evaluate the endovascular treatment of abdominal aortic aneurysm with percutaneous endoprosthesis in Cuban patients. Methods: It was conducted from January to April 2018 a retrospective, descriptive and qualitative study in 6 male patients with aneurysm of the abdominal aorta, selected randomly and who met the criteria of vascular endoprosthesis use and agreed with the performance of the procedure. Six devices were placed in an angiography room and it was used general anaesthetic and fluoroscopic guidance. Results: It was possible in a satisfactory way the endovascular treatment by percutaneous way in the six patients selected; just one presented a minor complication and he was discharged after 72 hours; and the rest were discharged in less than 24 hours. It was implemented for the first time in the country without complications the system of percutaneous closure called Proglide. Conclusions: Endovascular treatment by percutaneous way of abdominal aortic aneurysms with vascular endoprosthesis is an efficient alternative for conventional surgery in patients that met the criteria of use of the device(AU)

Resumen Introducción: Los aneurismas infecciosos constituyen una patología poco frecuente y se caracterizan por presentar infección de la pared del vaso implicado. El mejor tratamiento no está definitivamente establecido. Objetivo: Describir un caso de aneurisma infeccioso con manejo endovascular. Caso clínico: Presentamos un paciente de sexo masculino de 75 años que ingresa por cuadro compatible con abdomen agudo y que en el posoperatorio se pesquisa un aneurisma infeccioso del tronco celíaco, el cual se trata mediante una endoprótesis y manejo antibiótico. Discusión: El manejo tradicional del aneurisma infeccioso es la cirugía abierta que incluye la extirpación o exclusión del aneurisma y de su tejido perivascular infectado, pero conlleva gran morbimortalidad. Conclusión: El aneurisma infeccioso puede ser manejado de forma mínimamente invasiva con técnica endovascular, con baja morbilidad inmediata, pero con resultados a largo plazo aun no concluyentes.

Introduction: Infectious aneurysms are a rare disease and are characterized by infection of the involved vessel wall. The best treatment is definitely not established. Aim: To describe a case of infectious aneurysm with endovascular management. Case report: We present a 75-year-old male patient admitted to a table compatible with acute abdomen and that an infectious aneurysm of the celiac trunk is investigated in the postoperative period, treated with an endoprosthesis and antibiotic management. Discussion: The traditional management of the infectious aneurysm is open surgery that includes the removal or exclusion of the aneurysm and its infected perivascular tissue, but it leads to great morbidity and mortality. Conclusion: The infectious aneurysm can be managed minimally invasively with endovascular technique, with immediate low morbidity, but with long-term results that are still inconclusive.

Dacron vascular prostheses have been widely used in vascular surgery since the mid-1970s. They have been proven to be the most durable and reliable conduits for arterial replacement in aortic and peripheral surgeries for decades. However, an extremely rare complication, namely late non-anastomotic graft rupture, due to intrinsic structural prosthetic disruption can occur, resulting in acute hemorrhage or false aneurysm formation. We report a case of this rare complication due to non-anastomotic rupture of a bifurcated knitted Dacron aortic vascular graft in a patient who had undergone an aorto-bi-iliac bypass 6 years ago. The patient was successfully treated in an emergency setting with endovascular therapy using an iliac limb of an abdominal aortic endoprosthesis.

@#Introduction: Proximal femur resection and endoprosthetic reconstruction is the preferred treatment for extensive bony destruction and pathological fractures. Due to the relatively high cost of endoprosthesis, we adopted the modified unipolar hemiarthroplasty (MUH) for reconstruction when the mode of treatment was for palliation. Materials and Methods:This is a retrospective case study of six patients, who had bone and multi-organs metastases with extensive proximal femur involvement with pathologic fractures who underwent resection and MUH reconstruction during the period 2013 to 2017. All patients were classified as Group B / C based on Scandinavian Sarcoma Group survival scoring, with estimated survival of maximum six months. The basic MUH construct consisted of AustinMoore prosthesis which was secured to a Küntscher nail using cerclage wire and cemented into the femoral canal. Subsequently, the whole length of the prosthesis which remained outside the canal was coated with cement. Results:The mean age was 61.8 years. The mean survival was 3.9 months, post-operation. There was no implant failure during patients’ life span; however, a third of the patients developed infection. Wheel chair ambulation was started immediately post-operation for all patients, and two patients progressed to walking frame ambulation. The total cost of each construct was below US$490 in comparison to long-stem hemiarthroplasty (roughly US$ 1700). Conclusion: Our aim was to alleviate pain, facilitate rehabilitation, ease nursing care and improve quality of life for metastatic bone disease patients until end of life. MUH for the treatment of pathological fracture in proximal femoral metastases is a feasible palliative surgical modality in resource-limited settings.

We evaluated functional outcomes for patients who underwent surgery for resection and endoprosthesis replacement for primary tumours around the knee. We used the Musculoskeletal Tumour Society Scoring System (MSTS) for functional evaluations to compare differences between distal femur (DF) and proximal tibia (PT) placements. The study sample included 34 cases of distal femur and 20 cases of proximal tibia endoprosthesis replacement. Primary tumours were classified as follows: 33 osteosarcoma, 20 stage III giant cell tumour (GCT) and one case of mesenchymal chondrosarcoma. The mean MSTS score for both DF and PT endoprosthesis together was 21.13 (70.43%), and The MSTS scores for DF was 21.94 (73.13%) and PT was 19.75 (65.83%) Infection developed in 7 cases and 5 of which were PT endoprosthesis cases. Three deep infections required early, two-stage revision and resulted in poor MSTS scores. We conclude that endoprosthesis replacement for primary bone tumours had early good to excellent functional outcome. There were no differences in functional outcomes when comparing distal femur endoprostheses with proximal tibia endoprostheses.

The most common form in bile duct cancers is a highly desmoplastic cancer with a growth pattern characterized by periductal extension and infiltration. The prognosis of bile duct cancers, especially hilar cholangiocarcinoma, is limited by tumor spread along the biliary tree leading to refractory obstructive cholestasis, cholangitis, and liver failure. Although biliary endoprosthesis improves occlusion rates and reduces the number of therapeutic interventions, median survival time is not ameliorated. Photodynamic therapy (PDT) is a local photochemical tumor treatment that consists of a photosensitizing agent in combination with laser irradiation of a distinct wavelength. Tumor ablation with PDT combined with biliary stenting reduces cholestasis and significantly improves median survival time in selected patients with bile duct cancers.

Severe injury to the knee and the surrounding area is frequently associated with injury to ligaments of the knee joint and structures in the popliteal fossa. This case involved a popliteal artery occlusion, severe bone loss of distal femur, loss of collateral ligaments, and extensor mechanism destruction of the knee. Initially, prompt recognition and correction of associated popliteal artery injury are important for good results after treatment. After successful revascularization, treatment for severe bone loss of distal femur and injury of the knee joint must be followed. We treated this case by delayed reconstruction using modular segmental endoprosthesis after revascularization of the popliteal artery. This allowed early ambulation. At 36 months after surgery, the patient had good circulation of the lower limb and was ambulating independently.

A persistência do canal arterial (PCA) é uma anomalia relativamente freqüente e de simples correção. A correção envolve a ligadura do ducto com ou sem a sua secção. A anomalia em adultos pode provocar hipertensão pulmonar persistente e disfunção ventricular. A correção em adultos é controversa e de maior risco. Um caso de correção endovascular com acesso intra-abdominal da PCA em adulto é descrito.

The patent ductus arteriosus (PDA) is a common type of congenital heart defect and its correction is simple when performed early in life. Surgery is performed using stitches or clips. In adults, the anomaly can lead to pulmonary hypertension and ventricular dysfunction. Surgery in adults is controversial and high-risk. This report describes an alternative endovascular approach in an adult patient.

PURPOSE: To establish a correlation between intrasac pressure measurements of a pressure sensor and an angiographic catheter placed in the same aneurysm sac before and after its exclusion by an endoprosthesis. METHODS: Patients who underwent endovascular abdominal aortic aneurysm repair and received an EndoSureTM wireless pressure sensor implant between March 19 and December 11, 2004 were enrolled in the study. Simultaneous readings of systolic, diastolic, mean, and pulse pressure within the aneurysm sac were obtained from the catheter and the sensor, both before and after sac exclusion by the endoprosthesis (Readings 1 and 2, respectively). Intrasac pressure measurements were compared using Pearson's correlation and Student's t test. Statistical significance was set at p<0.05. RESULTS: Twenty-five patients had the pressure sensor implanted, with simultaneous readings (i.e., recorded by both devices) obtained in 19 patients for Reading 1 and in 10 patients for Reading 2. There was a statistically significant correlation for all pressure variables during both readings, with p<0.01 for all except the pulse pressure in Reading 1 (p<0.05). Statistical significance of pressure variations before and after abdominal aortic aneurysm exclusion was coincident between the sensor and catheter for diastolic (p>0.05), mean (p>0.05), and pulse (p<0.01) pressures; the sole disagreement was observed for systolic pressure, which varied, on average, 31.23 mmHg by the catheter (p<0.05) and 22 mmHg (p>0.05) by the sensor. CONCLUSION: The excellent agreement between intrasac pressure readings recorded by the catheter and the sensor justifies use of the latter for detection of post-exclusion abdominal aortic aneurysm pressurization.

Purpose: This multicenter study was carried out to estimate the clinical and radiological results of cemented bipolar endoprosthesis replacement arthroplasty of a hip fracture in patients aged over 50 years in Jeju Island. Materials and Methods: Eighty-eight hips underwent bipolar endoprosthesis in 2002. Thirty-two patients died during the follow-up period and 7 patients refused a radiological evaluation or an interview. Two patients who underwent cementless bipolar endoprosthesis were excluded. Forty- nine hips (48 patients) completed the average 27 months follow-up. A neck fracture was involved in 40 hips (39 patient) and an intertrochanteric fracture was involved in 9 hips (9 patients). The average age was 77.7 years. The results were evaluated using clinical and radiological methods. Results: At the last follow-up, the average Harris hip score was 70.1 and 22 hips (45%), which indicated excellent and good results, respectively. Among the 42 patients with normal activity at the preoperative period, 28 patients were still active at the final follow-up. The number of medical illnesses and the severity of mental deterioration were also associated with the poor Harris hip scores. The pressurization cementing technique was found to be excellent at the radiological evaluation. One femoral stem appeared to have loosened and subsided but there was no revision surgery. Conclusion: The clinical result of the cemented bipolar endoprosthesis in multicenter study showed that the only 45% of patients showed results >good. The major factors influencing the results were the postoperative activity, the number of medical illnesses, and the severity of the mental changes.

Introducción: la colocación endoscópica de stents para descomprimir una obstrucción biliar es un tratamiento comúnmente utilizado para enfermedades malignas de la vía biliar y para estenosis benignas de la misma. Se han descrito complicaciones inusitadas derivadas de la colocación de endoprótesis biliares, incluyendo la migración. Se presenta un caso clínico con el objetivo de compartir con la comunidad científica una rara complicación y la única publicada, secundaria a la migración de un stent biliar. Caso clínico: mujer de 47 años de edad, con estenosis de ámpula de Vater benigna, a quien se le colocó endoprótesis biliar, con la cual mejoró clínicamente. Posterior a la colocación del stent se le realizó colecistectomía abierta con exploración de vías biliares. Al año y medio posterior a la colocación del stent, la paciente presentó dolor vago en abdomen bajo y disuria; se le practicaron estudios de imagen donde se observó un extremo del stent biliar en colon sigmoides y otro en vejiga. Se realizó intervención quirúrgica encontrando fístula colovesical, la cual se resolvió en un solo tiempo quirúrgico. La paciente fue egresada con resultados satisfactorios.

BACKGROUND: The endoscopic placement of endoprostheses to decompress biliary obstruction is a commonly used treatment for malignant biliary diseases and is also used in the treatment of benign biliary strictures. Unusual complications of endoprosthesis placement have been described and include the migration of the stent. We present a case to share with the scientific community, an unusual complication secondary to the migration of a biliary stent that has not previously been reported to our knowledge. CASE REPORT: We present the case of a 47-year-old female with a diagnosis of benign papillary stenosis. The patient received a biliary endoprosthesis with clinical improvement. Later she underwent open cholecystectomy and common duct exploration. At consultation 18 months later, the patient presents with indistinct lower abdominal pain and dysuria. We performed imaging studies where the biliary stent was observed, partly in the sigmoid colon and partly in the bladder. The patient underwent surgery where a colovesical fistula was found and treated during the same surgical event. The patient was discharged succesfully.

Objective: Hilar cholangiocarcinoma is one of the most common causes of biliary tract obstruction in Thailand. However, in most patients, the tumors are unresectable. Endoscopic retrograde cholangiopancreatography (ERCP) with endoprosthesis insertion can provide effective internal biliary drainage in these patients; however, there are still some controversy regarding the complications, success rate and technical aspect of this approach. The aim of this study was to report results of palliative endoscopic endoprosthesis insertion using plastic stents in unresectable hilar cholangiocarcinoma. Methods: We analyzed 72 sessions of ERCP with plastic stent insertion in 61 patients with unresectable hilar cholangiocarcinoma, treated at the Endoscopic Unit, Department of Surgery, Siriraj Hospital from 1999-2001. Statistical analysis were done using chi – square test. Results: In 72 sessions of ERCP with plastic stent insertion, overall successful drainage was 48 %. Early complication was found in 13 sessions (18%) with cholangitis 13.9%, pancreatitis 2.8%, bleeding 2.8% and intra-abdominal collection 2.8%. Unilateral stent insertion was done in 94% (right side 43.4%, left side 49.1%) and bilateral stent insertion was performed in 7.5%. The success rate of right duct stent insertion was 63.1% while that of left duct stent insertion was 36.4% (p<0.01). Mortality rate was 2.98%. Conclusion: Endoscopic endoprosthesis insertion using plastic stent is an effective method for palliative biliary drainage in patients with unresectable hilar cholangiocarcinoma with acceptable morbidity and mortality rate.

Although the reconstruction with tumor prosthesis is a routine procedure for extremity sarcomas, this option has some technical limitation in children under 10 years old. Customized expandable tumor prosthesis is too expensive in most cases and arthrodesis of any kind is not functional. This report presents one case of osteosarcoma of distal femur in eight years old child which was reconstructed with adult type total elbow endoprosthesis as a reconstructive option, and includes brief review of the literature.

Although the occurrence of fatal pulmonary embolism may be diminishing, it still accounts for a substantial proportion of postoperative deaths in the middle-aged and older persons, especially among those undergoing major orthopedic surgery, despite improvements in patient management. We experienced cardiac arrest during bipolar endoprosthesis. Cardiopulmonary resuscitation was started and the transesophageal echocardiogram showed right heart failure. We suspected acute pulmonary thromboembolism and decided to perform thromboembolectomy with cardiopulmonary bypass. A massive old blood clot and a 1.0 x 1.5 cm thrombus were removed from both pulmonary arteries. However, despite massive fluid therapy and the use of inotropic agent, the patient failed to recover successfully with postoperative management in the intensive care unit.

Palliative treatment of malignant biliary obstructions represent the principal indications of endoscopic or percutaneous transhepatic implantation of endoprostheses. Many kinds of biliary stents have been used to maintain patency of the bile ducts obstructed by benign or malignant strictures. However, the biliary stent in current use, has a tendency to become blocked. In order to maintain a long-term stent patency before clogging, biliary stents with large diameters are needed and some kinds of expandable metal stents are proposed. The Hanaro stent (Sooho medi-tech Co. LTD, Seoul, Korea) is a modified Gianturco Z biliary stent, made of 0,01-inch stainless steel wire with a zigzag pattern. It has a spiral, cylindrical configuration and is 10 mm in expanded diameter. It hes been used only with the percutaneous transhepatic technique. In this article, we describe a new method for endoscopic retrograde placement of a modified Gianturco Z biliary stent. This report describes our experience on endoscopic application of a modified Gianturco Z biliary stent in a patient with malignant obstruction of the distal common bile duct.
