ABSTRACT

La ecografía tiroidea es la principal herramienta diagnóstica en el manejo de los nódulos tiroideos, siendo la presencia de microcalcificaciones un signo de malignidad. Sin embargo, existen escasas publicaciones acerca de la presencia de microcalcificaciones en ausencia de nódulo identificable y su asociación con cáncer de tiroides. Presentamos un caso de una mujer de 26 años, que, tras hallazgo incidental de bocio, se describe en ecografía un tiroides con alteración difusa de su ecogenicidad e imágenes compatibles con microcalcificaciones sin claro nódulo definido en su polo inferior. Tras realización de punción aspiración con aguja fina de la lesión con resultado Bethesda categoría 5, se decide realizar tiroidectomía total, presentando estudio histológico con diagnóstico de carcinoma papilar de tiroides variante clásica con metástasis ganglionares p(T1bN1a). Tras una revisión sistemática, los estudios hasta hoy publicados sugieren que la presencia de microcalcificaciones aisladas sin nódulo identificable debe considerarse un importante factor de riesgo de cáncer de tiroides, especialmente en gente joven, y en aquellas asentadas sobre una tiroiditis de Hashimoto. Por ende, resulta imperativo mantener una alta sospecha ante el hallazgo de este tipo de lesiones, recomendando una valoración exhaustiva de las mismas con la realización de una punción aspiración con aguja fina a todas las lesiones con dichas características.


Thyroid ultrasound is the main diagnostic tool in the management of thyroid nodules, with the presence of microcalcifications being a sign of malignancy. However, there are few publications about the presence of microcalcifications in the absence of an identifiable nodule and its association with thyroid cancer. We present a case of a 26-year-old woman who, after an incidental finding of goiter, a thyroid with diffuse echogenicity alteration and images compatible with microcalcifications without a clear nodule defined in the lower pole of the lobe is described on the ultrasound. After performing a fine needle aspiration of the lesion resulting in a Bethesda category 5, a total thyroidectomy was performed, presenting in the histological study a diagnosis of a classic variant of a papillary thyroid carcinoma with lymph node metastases p (T1bN1a). After a systematic review, the studies previously published suggest that the presence of isolated microcalcifications without an identifiable nodule should be considered an important risk factor for thyroid cancer, especially in young people, and in those with a concomitant Hashimoto's thyroiditis. Therefore, it is imperative to maintain a high suspicion of the discovery of this type of lesion, recommending an exhaustive assessment of them with the performance of a fine needle aspiration to all lesions with these features.

ABSTRACT

Abstract A 68-year-old man previously subjected to radiotherapy had a prior aortic valve replacement due de radiation induced calcification of the aortic valve. Presently the patient developed severe calcification of the mitral valve ring leading to critical mitral valve stenosis. A supra annular implantation of an On X Conform valve was successfully achieved. The clinical course was uneventful, and the echocardiographic evaluation demonstrated a normal function of the valve. Different alternatives for the surgical management of this complication are discussed.

ABSTRACT

OBJECTIVE@#To discuss the efficacy and safety of simultaneous bilateral endoscopic surgery (SBES) for bilateral upper urinary tract calculi, and to summarize the initial experience.@*METHODS@#Patients diagnosed with bilateral upper urinary tract calculi who underwent SBES in the Department of Urology, Beijing Chao-Yang Hospital from January 2019 to January 2020 were enrolled retrospectively. The demographic and clinical data of the patients were recorded, and the operation status, stone free rate (SFR) and peri-operative complications were analyzed. The primary end point was SFR, and second end point was peri-operative complications.@*RESULTS@#A total of 23 patients underwent SBES, of which SBES was completed in 19 patients (12 males, and 7 females). The mean age was (41.3±12.0) years. Fourteen patients underwent modified supine position surgery and 4 patients in prone split-leg position. There was no statistical difference in the demographic and baseline clinical data of the patients in different positions. One patient underwent right percutaneous nephrolithotomy (PCNL) and left endoscopic combined intra-renal surgery (ECIRS) in the prone split-leg position, while 18 patients received simul-taneous surgery with PCNL and contralateral retrograde intra-renal surgery (RIRS). The mean anesthesia and operation time was (128.7±26.5) min and (70.7±20.3) min, respectively, which was significantly longer in the patients with prone split-leg position than in the patients with modified supine position, anesthesia time in the patients with prone split-leg position and modified supine position: (148.4±20.4) min vs. (121.6±25.3) min, respectively, t=-2.121, P=0.049, while the operation time in the patients with prone split-leg position and modified supine position: (86.4±21.1) min vs. (65.1±17.4) min, respectively, t=-2.222, P=0.040. There was no significant difference between the two groups in indwelling of nephrostomy [prone split-leg position and modified supine position: (2.6±0.9) d vs. (2.1±1.0) d, respectively; t=-0.880, P=0.391] and the length of hospital stay [prone split-leg position and modified supine position: (6.0±2.7) d vs. (5.2±1.8) d, respectively; t=-0.731, P=0.475]. One month after the operation, the SFR was 78.9%, and 3 patients had minor peri-operative complications (Clavien-Dindo grades Ⅰ/Ⅱ) without any serious complications (Clavien-Dindo grades Ⅲ/Ⅳ/Ⅴ).@*CONCLUSION@#The simultaneous bilateral endoscopic surgery would decrease the operation time and anesthesia exposure under the premise of ensuring the SFR, which is helpful to reduce the risk of peri-operative complications, especially to the patients who can not tolerate the second-stage or long-time operation.

ABSTRACT

Los trastornos metabólicos ocasionados por la insuficiencia renal y la diálisis para su tratamiento pueden conducir a la precipitación de sales de fosfato cálcico con la consecuente formación de tumores en diversas localizaciones. Estos pueden ser únicos o múltiples, pudiendo ocasionar obstrucción y compresión de distintas estructuras anatómicas con la consecuente alteración funcional. Si bien el manejo clínico de las alteraciones antes citadas es fundamental, la cirugía adquiere relevancia en estas situaciones. Se presenta un caso de Calcinosis Tumoral única ubicada en el tercio anterior del septum nasal, ocasionando obstrucción de la fosa nasal. La tomografía computada orientó el diagnóstico y la resección tumoral completa por vía nasal fue el tratamiento elegido. El informe de anatomía patológica confirma el diagnóstico de Calcinosis Tumoral. A los nueve meses de seguimiento en el postoperatorio no se evidencia recidiva.


Metabolic disorders caused by chronic renal failure and dialysis for its treatment can lead to the precipitation of calcium phosphate salts with the consequent formation of tumors in various locations. These can be single or multiple, and may cause obstruction and compression of different anatomical structures with consequent functional alteration. Although the clinical management of the above mentioned alterations is fundamental, the surgery acquires relevance in these situations. We present a case of unique tumoral calcinosis located in the anterior third of the nasal septum, causing obstruction of the nasal fossa. Computed tomography guided diagnosis and complete tumor resection by nasal route was the treatment chosen. The pathological anatomy report confirms the diagnosis of tumor calcinosis. At nine months post-operative follow-up there was no evidence of tumor recurrence.

ABSTRACT

Las calcificaciones del manguito rotador afectan mayormente al tendón del supraespinoso. El compromiso del tendón del subescapular es menos frecuente y sólo unos pocos casos han sido reportados. Presentamos un caso de una calcificación del subescapular en un paciente sin respuesta al tratamiento conservador, que fue tratado con la remoción completa de la misma y la posterior reparación del defecto residual con un arpón de doble sutura reforzada. Un año luego de la cirugía el paciente se presentaba sin dolor, con movilidad completa y sin restos de calcio en los estudios postoperatorios. La combinación de la remoción completa de la calcificación y la subsecuente reparación del defecto con arpones en forma artroscópica puede resultar en excelentes resultados funcionales, sin comprometer la integridad del manguito rotador en pacientes con calcificaciones del subescapular. Nivel de Evidencia: V...


The supraspinatus tendon is the most common tendon associated with the calcific tendinosis of the rotator cuff. The subscapularis tendon is rarely affected, and only a few prior cases have been reported. We present a case of a subscapularis tendon calcification in a patient with a failed conservative treatment that was treated arthroscopically with complete removal of the calcific deposit and posterior repair of the defect with suture anchors. One year after surgery the patient had no pain, he had full range of motion and there were not residual calcium deposits in the postoperative studies. The combination of complete calcium removal and posterior repair with suture anchors can led to excellent functional outcomes without compromising the integrity of the rotator cuff in patients with calcifications of the subscapularis tendon.

ABSTRACT

Introducción: Las calcificaciones del manguito rotador son una causa frecuente de dolor crónico de hombro y pueden provocar a una limitación funcional importante del mismo. Si bien la mayoría de los pacientes responden favorablemente al tratamiento conservador algunos requieren cirugía. La cirugía artroscópica es una alternativa con baja morbilidad y ventajas cosméticas. Objetivos: Evaluar los resultados clínicos luego de la remoción artroscópica de calcificaciones del supraespinoso y reparación del manguito rotador sin acromioplastía. Materiales y Métodos: Realizamos una evaluación retrospectiva de los resultados clínicos de la remoción artroscópica de los depósitos de calcio y posterior reparación del manguito rotador sin acromioplastía. Se evaluaron 30 pacientes consecutivos con una edad media de 49.2 años. El seguimiento promedio fue 35 meses (12 a 88 meses). EL dolor se evaluó subjetivamente con la escala visual análoga EVA pre y postoperatorio. La evaluación funcional se realizó con el score de Constant, UCLA y Quick DASH. Se realizaron radiografías postoperatorias y RNM para evaluar las calcificaciones remanentes y la indemnidad de la reparación del supraespinoso. Resultados: La EVA mejoró significativamente desde un promedio de 8.7 antes de la cirugía a 0.8 luego de la operación (p<0.001). El Constant promedio aumentó de un promedio de 23.9 antes de la cirugía a 85.3 en el postoperatorio (p< 0.001), el Quick DASH disminuyó de un promedio de 47.3 preoperatorio a 8.97 en el postoperatorio (p< 0.001) y el escore de UCLA aumentó de un promedio de 15.8 en el preoperatorio a 32.2 en el postoperatorio (p< 0.001). Conclusiones: La remoción artroscópica y la reparación del manguito rotador sin acromioplastía disminuye significativamente el dolor y mejora la función del hombro en pacientes con calcificaciones del supraespinoso.

Background: Calcified rotator cuff tendinitis is a common cause of chronic shoulder pain that leads to significant pain and functional limitations. Although most patients respond well to conservative treatment, some eventually require surgical treatment. Arthroscopic surgery is a valid option due to lower morbidity and better cosmetics. Purposes: Evaluate the clinical outcome after calcific deposit arthroscopic removal and rotator cuff repair without acromioplasty for the treatment of calcified tendinitis of the supraspinatus tendon. Methods: We retrospectively evaluated the clinical outcomes of the arthroscopic removal of calcium deposits and rotator cuff repair without acromioplasty of 30 consecutive patients with a mean age of 49.2 years. The mean follow up was 35 months (range 24-88 months). Preoperative and postoperative functional assessment was performed using the Constant score, UCLA score, and Quick DASH. Pain was subjectively measured by with a visual analog scale (VAS). Radiographs and magnetic resonance (MRI) were performed to evaluate the recurrence of calcifications and the indemnity of the supraspinatus tendon repair. Results: The VAS improved significantly from a mean of 8.7 before surgery to 0.8 after the operation (p< 0.001). The mean Constant score increased from 23.9 preoperatively to 85.3 postoperatively (p<0.001) the mean Quick DASH score decreased from 47.3 preoperatively to 8.97 postoperatively (p< 0.001) and the UCLA score increased from 15.8 preoperatively to 32.2 postoperatively (p< 0.001). MRI examination at last follow-up (70 % of patients) showed no tendon tears and 96.2% of patients was satisfied with their results. Conclusions: Arthroscopic removal and rotator cuff repair without acromioplasty can lead to good results in patients with symptomatic calcifying tendonitis of the supraspinatus tendon. Level of Evidence: IV. Study Design: Cases Series...

ABSTRACT

Coral reef aorta is described as an uncommon entity characterized by the presence of coarse calcifications, which are developed in the visceral aorta. These calcifications grow toward the lumen of the artery and can result in significant stenosis, so that causing malperfusion of the lower limbs, visceral ischemia or hypertension secondary to renal involvement. We report here a case of a 54-year-old patient with coral reef aorta and symptomatic. The clinical presentation of the patient required the surgical approach. A review of literature in major databases was conducted to compare health-related aspects of the disease presentation and management. Coral reef aorta should be considered as the diagnosis for patients with visceral and limbs ischemia. The approach in our case was consistent with other studies previously published in the literature.


A aorta em recife de corais é descrita como uma entidade incomum caracterizada pela presença de calcificações grosseiras, que se desenvolvem na aorta visceral. Essas calcificações crescem em direção ao lúmen da artéria e podem resultar em estenose significativa, gerando má perfusão dos membros inferiores, isquemia visceral ou hipertensão secundária ao acometimento renal. Relata-se aqui o caso de um paciente de 54 anos portador de aorta em recife e sintomático. O quadro clínico do paciente exigiu abordagem cirúrgica. Foi realizada revisão de literatura nas principais bases de dados para comparar os aspectos relacionados à apresentação e à conduta da doença. Em pacientes com sinais de isquemia visceral ou em membros inferiores, deve-se considerar o diagnóstico de aorta em recife de coral. A abordagem, no caso relatado, foi consistente com estudos publicados anteriormente na literatura.

ABSTRACT

OBJETIVO: A troca valvar aórtica é procedimento rotineiro com risco aceitável. Em alguns casos, a mortalidade é elevada, contraindicando o procedimento. O implante minimamente invasivo transcateter de valva aórtica parece ser alternativa, reduzindo a morbimortalidade. A avaliação dos resultados clínicos, segurança e eficácia do procedimento são o objetivo desse estudo. MÉTODOS: Uma prótese transcateter, balão expansível foi utilizada em 33 casos de alto risco. EuroScore médio foi de 39,30% e STS score de 30,28%. Oito pacientes apresentavam disfunção de bioprótese e o restante, estenose aórtica calcificada. Os procedimentos foram realizados em ambiente cirúrgico híbrido, sob controle ecocardiográfico e fluoroscópico. Através de minitoracotomia esquerda, as próteses foram implantadas pelo ápice ventricular, sob estimulação de alta frequência ou choque hemorrágico. Foram realizados controles clínicos e ecocardiográficos. RESULTADOS: A correta liberação da prótese foi possível em 30 casos. Três conversões ocorreram. A mortalidade operatória foi de um caso e a mortalidade em 30 dias, 18,18%. O gradiente médio reduziu de 43,58 para 10,54 mmHg. A fração de ejeção apresentou aumento significativo após o 7º pós-operatório. Insuficiência aórtica residual esteve presente em 30,30% dos pacientes. Ocorreu uma complicação vascular periférica e um caso de bloqueio atrioventricular total. Um paciente apresentou acidente vascular cerebral. A mortalidade em 30 dias foi de 18,18%. CONCLUSÃO: O implante transapical de valva aórtica transcateter é procedimento seguro e com resultados de médio prazo satisfatórios. São necessários estudos de longo prazo com maior poder amostral no intuito de determinar resultado hemodinâmico, qualidade de vida e sobrevida em longo prazo.


OBJECTIVE: Aortic valve replacement is a routine procedure with acceptable risk, but in some cases, such risk can justify contraindication. Minimally invasive transcatheter aortic valve implantation has emerged as an alternative, with lower morbidity and mortality. The aim of this study was clinical, safety and efficacy assessment. METHODS: Thirty-three high risk patients underwent transcatheter balloon expandable aortic valve implantation. Mean Logistic EuroScore risk was 39.30% and STS score 30.28%. Eight patients presented with dysfunctional bioprosthesis, remaining ones presented calcified aortic stenosis. Procedures were performed in a hybrid OR under fluoroscopic and echocardiography guidance. Using a left minithoracotomy the prosthesis were implanted trough the ventricular apex under rapid ventricular pacing or hemorrhagic shock. Echocardiographic and angiographic controls were performed. RESULTS: Implant was feasible in 30 cases. Three conversions occured. There was only one case of operative death. Median transvalvular aortic gradient reduced from 43.58 mmHg to 10.54 mmHg. Left ventricular function improved in the first 7 postoperative days. Paravalvular aortic regurgitation was mild and present in 30.30%. One case presented major vascular complication and another one permanent pacemaker implant. One major stroke case occurred. Overall 30-day mortality was 18.18%. CONCLUSION: The transapical implantation of catheter mounted bioprosthesis is a safe procedure with acceptable midterm results. Long term follow-up with increased sample power is mandatory in order to access hemodynamic, life quality and survival.

ABSTRACT

Tumor amorfo calcificado do coração consiste em uma massa cardíaca de natureza não-neoplásica, rara, que pode simular malignidade e causar sintomas por causar obstrução ou embolização de fragmentos calcificados. Apresentamos um caso de tumor em jovem de 17 anos, sexo masculino, em valva tricúspide, com achados patológicos clássicos. Preferiu-se abordar por esternotomia mediana clássica, instalação do circuito de circulação extracorpórea e atriotomia direita, exérese do tumor, plastia de DeVega na valva tricúspide e bicuspidização da mesma. O estudo anatomopatológico demonstrou presença de extensa calcificação e áreas de metaplasia óssea. O paciente evoluiu bem no pós-operatório, recebendo alta hospitalar no 8º dia pós-operatório.


Calcified amorphous tumor of the heart consists of a cardiac mass of rare nonneoplastic nature that mimics malignancy and causes symptoms due to obstruction or embolization of calcific fragments. We present a case of tumor 17-year-old young, male, in tricuspid valve, with classic pathological findings. It was preferred to approach for classic median esternotomy, installation of the circuit of extracorporal circulation and right atriotomy, exereses of tumor, DeVega's plasty in tricuspid valve and bicuspidization. The amatomopathological study demonstrated presence of extensive calcification and metaplastic bone areas. The patient had an uneventful hospitalization.

ABSTRACT

PURPOSE: To present our experience and discuss the various endourological approaches for treating forgotten encrusted ureteral stents associated with stone formation. MATERIALS AND METHODS: From July 2006 to December 2008, 14 patients (11 men and 3 women) with encrusted ureteral stents were analyzed. The average indwelling time of the stent was 4.9 years (range 1 to 12). Plain-film radiography was used to evaluate encrustation, stone burden, and fragmentation of the stents. Intravenous urogram and a Tc99m diethylene triamine penta acetic-acid renogram was used to assess renal function. RESULTS: In seven patients, the entire stent was encrusted, in three patients the encrustation was confined to the ureteral and lower coil part of the stent, two patients had encrustation of the lower coil, and minimal encrustation was observed in two patients. Percutaneous nephrolithotomy was performed in 5 cases and retrograde ureteroscopy with intra-corporeal lithotripsy in 9 patients. Cystolithotripsy was used to manage the distal coil of the encrusted stent in eight patients. Simple cystoscopic removal of the stents with minimal encrustation was carried-out in two cases. Looposcopy and removal of the stent was performed in one patient with an ileal conduit and retained stent. Only one patient required open surgical removal of the stent. Thirteen out of 14 patients were rendered stone and stent free in one session. All except two stents were removed intact and stone analysis of encrustation and calcification revealed calcium oxalate and calcium phosphate in the majority of the cases. CONCLUSION: Endourological management of forgotten encrusted stents is highly successful and often avoids the need for open surgical techniques.

ABSTRACT

OBJETIVO: O objetivo deste estudo foi avaliar a atividade embólica de pacientes portadores de estenose aórtica calcificada submetidos a troca valvar aórtica por meio da filtração intra-aórtica com dispositivo EMBOL-X® System (Edwards Lifesciences Inc., Mountain View, CA, USA). MÉTODOS: De janeiro de 2007 a julho de 2007, foi utilizado o filtro intra-aórtico EMBOL-X após o despinçamento aórtico em 13 portadores de estenose aórtica calcificada submetidos a troca valvar aórtica consecutivamente. A média de idade dos pacientes foi 63,7 anos (34-79) e 61,5% eram do sexo feminino. A média do tempo de CEC foi 60,2±7,5 (45-72) minutos e a média do tempo despinçamento aórtico foi 50±7,5 (35-63) minutos. Após a retirada dos filtros, eles foram fixados em formalina, analisados macroscopicamente e quantificados os fragmentos capturados. Foi realizado exame histológico do material capturado. RESULTADOS Não foi observado nenhum caso de complicação neurológica. Nenhum paciente apresentou insuficiência renal pós-operatória. Não houve óbitos hospitalares. Partículas embólicas foram encontradas em cinco (38,5%) dos filtros. Das partículas embólicas capturadas, em dois (40%) filtros havia fibrina, dois (40%) apresentavam tecido conjuntivo, um (20%) continha hemácias e em um não foi possível determinar a natureza. CONCLUSÃO: O dispositivo EMBOL-X® System foi efetivo na captação de fragmentos intra-aórticos na substituição da valva aórtica em pacientes com estenose aórtica calcificada.


OBJECTIVE: This study aims to analyze the embolic activity in patients with calcified aortic stenosis who underwent aortic valve replacement using intra-aortic filtration with an EMBOL-X® System device (Edwards Lifesciences Inc., Mountain View, CA, USA). METHODS: From January 2007 to July 2007, 13 consecutive patients with calcified aortic stenosis, who underwent isolated aortic valve replacement using intra-aortic filtration by an EMBOL-X® System for 5 minutes after aortic clamp release, were evaluated. Mean patient age was 63.7 years (range 34 to 79 years) and 61.5% were female. The mean bypass time was 60.2 ± 7.5 minutes (range 45 to 72 minutes) and the mean cross-clamp time was 50 ± 7.5 minutes (range 35 to 63 minutes). Following removal, each filter was fixed in formalin and analyzed macroscopically with the captured fragments being counted. Histological examinations of the captured material were performed. RESULTS: There were no strokes or gross neurological events. There were no cases of postoperative renal failure. No deaths were reported during hospitalization. Particulate emboli were found in five (38.5%) of the filters. On histological analysis of the particulate emboli captured, two (40%) contained fibrin, two (40%) presented conjunctive tissue, one (20%) contained red blood cells and in one it was not possible to determine the nature of the particulates captured. CONCLUSION: The EMBOL-X® System device was effective in particulate emboli capture in aortic valve replacement surgery of patients with calcified aortic stenosis.
