RESUMO

INTRODUCCIÓN: El traumatismo penetrante cardiaco (TPC) por sus características y en particular por su alta mortalidad, constituye un desafío quirúrgico permanente. OBJETIVOS: Describir las características, resultados inmediatos y factores pronósticos en TPC. MATERIALES Y MÉTODO: Estudio descriptivo transversal, revisión de protocolos prospectivos de traumatismo torácico, registros de pabellón y fichas clínicas. Período enero de 1990-diciembre de 2017. Se incluyeron todos los pacientes con TPC operados. Se describen y analizan diversas variables. Se realizó regresión logística con análisis univariado y multivariado para identificar variables asociadas a morbilidad, deterioro neurológico y mortalidad. RESULTADOS: 220 pacientes operados por TPC, 209 (95,0%) hombres, edad promedio 30,4 ± 13,3, mediana 27 años. Mecanismo: agresión en 202 (91,8%). El agente traumático fue en 186 (84,5%) arma blanca, en 21 (9,5%) arma de fuego. Presentaban taponamiento 169 (76,8%) pacientes, ingresaron en shock 103 (46,8%) y en paro cardiorrespiratorio 20 (9,1%). Vía de abordaje fue esternotomía en 157 (71,4%), toracotomía izquierda en 58 (26,4%). Las cavidades cardiacas lesionadas más frecuentes fueron ventrículo derecho en 110 (50,0%), ventrículo izquierdo en 72 (32,7%). Se hospitalizaron en UCI en el postoperatorio 135 (61,4%), se transfundieron 74 (33,6%), presentaron complicaciones 60 (27,3%) y se reoperaron 21 (9,5%). Mortalidad 28 (12,7%). La estadía postoperatoria tuvo una mediana de 6 días (rango 1-150). Se identificaron factores pronósticos. DISCUSIÓN: Los TPC operados son más frecuentes en hombres agredidos con arma blanca, la cavidad lesionada más frecuente es el ventrículo derecho. Nuestra morbimortalidad es comparable con series internacionales.


INTRODUCTION: Penetrating cardiac trauma (PCT) constitute a permanent surgical challenge due to it characteristics and high mortality. AIM: To describe the findings, outcomes and prognostic factors in PCT. MATERIAL AND METHOD: Cross-sectional descriptive study, review of prospective thoracic trauma protocols and surgical registries. Period January 1990-December 2017. All patients with PCT were included. Various variables are described and analyzed. Univariate and multivariate analysis were performed to identify factors associated with morbidity, neurologic dysfunction and mortality. RESULTS: 220 patients PCT, 209 (95.0%) men, mean age 30.4 ± 13.3, median 27 years. Mechanism: Aggression in 202 (91.8%). The traumatic agent was cold steel in 186 (84.4%) and fire arm in 21 (9.5%). 169 (76.8%) patients presented with tamponade, 103 (46.8%) shock and 20 (9.1%) cardiopulmonary arrest. Approach was sternotomy in 157 (71.4%), left thoracotomy in 58 (26.4%). The most common injured areas were right ventricle in 110 (50.0%), left ventricle in 72 (32.7%). 135 (61.4%) patients needed postoperative ICU and 74 (33.6%) were transfused. Complications occurred in 60 (27.3%). Twenty-one (9.5%) were reoperated. Mortality 28 (12.7%). The postoperative median stay was 6 days (Range 1-150). Prognostic factors were identified. DISCUSSION: Operated PCT are more frequent in men with stab wound, the most common injured area is the right ventricle. The morbidity and mortality is comparable with international series.

RESUMO

BACKGROUND: Thymectomy improves clinical outcomes and decreases the need for medical treatment in patients with myasthenia gravis (MG). AIM: To describe the immediate and long-term results of extended transsternal thymectomy (ETT) in patients with MG. MATERIAL AND METHODS: A review of databases, surgical protocols, clinical records and interviews of patients subjected to extended transsternal thymectomy for MG between 1990 and 2016. Perioperative clinical characteristics, anticholinesterase treatment, immediate and remote surgical results were analyzed and patients were followed from one to 10years. RESULTS: We studied 58 patients aged 35 ± 14years (72%) women. In the preoperative period, according to Osserman classification, nine patients (15,5%) were in grade I, eight (13,8%) in grade IIA 8 and 40 (69%) in grade IIB. The pathological study of the surgical piece showed thymic hyperplasia in 39 cases (67,2%). Four patients had postoperative complications but none died. In the Follow-up at 1, 3, 5, 8 and 10years the Masaoka palliation rate was 71.7, 77.5, 67.7, 70.0 and 70,6% respectively. The figures for remission rate were 13.0, 15.0,19.4, 35.0 and 35,3% respectively. The figures for Zielinski positive results were 79.6, 87.5, 87.1, 90.0 and 82,4% respectively. The DeFilippi score improved by 80.4, 87.5, 87.1, 90.0 and 82.4% respectively. The Myasthenia Gravis Foundation of America Post-Intervention State improved by 67.4, 77.5, 77.5, 75.0 and 70,6% respectively. Mean Myasthenia Gravis Activities of daily living (MGADL) and Myasthenia Gravis Quality of life scale 15 (MGQOL 15) were 1.65 and 6.31 respectively. CONCLUSIONS: In selected patients with MG, extended transsternal thymectomy in MG has good immediate and long-term results.

RESUMO

BACKGROUND: Trauma is the leading cause of death in young patients and thoracic trauma (TT) is responsible for 25-35% of trauma deaths. AIM: To describe and compare features, trauma severity indexes and morbidity of patients admitted for TT in the past three decades. MATERIAL AND METHODS: Review of a TT database, operative notes and medical records of patients. These were separated by decade of admission (1981-1990, 1991-2000, 2001-2010). TT characteristics were compared. Injury Severity Score (ISS), Revised Trauma Score (RTS-T) and Trauma Injury Severity Score (TRISS) were calculated. RESULTS: A total of 3,068 TT were reviewed. In the 1981-1990 period, 604 cases of TT were registered (19.7%), in the 1991-2000 period, 1,070 cases (34.9%) and in the 2001-2010 period, 1,394 cases (45.4%) (p < 0.05). The ages of patients in each of these periods were 34.9 ± 15.5, 33.9 ± 16.2 and 35.7 ± 18.2 years respectively (p < 0.05). The proportion of patients aged 65 years or more were 6.6, 7.7 and 10.1% respectively, the proportion of females was 6.1, 9.4 and 12.0%, respectively. The causing agents per decade were knife wounds in 51.5, 61.1 and 60.0% of cases respectively, firearms in 2.5, 3.3 and 5.0% of cases respectively, multiple trauma in 13.9, 14.5 and 9.0% respectively and morbidity in 18.7, 19.7 and 11.7%, respectively. The ISS per decade was 11.9 ± 6.5, 12.9 ± 6.9 and 10.4 ± 6.8 respectively. No significant difference were found in mortality (1.5, 3.0, 2.0% respectively) or TRISS score (2.7, 3.2 and 3.8% respectively). CONCLUSIONS: An increase in the number of hospital admission for TT has occurred in the last three decades, with an increase in the proportion of admissions of subjects aged 65 years or more, females and with firearm injuries.

RESUMO

Doege-Potter syndrome is characterized for hypoglycemia associated with solitary pleural fibrous tumors. We report a 38-year-old woman with a history of weight loss, malaise and edema. After an episode of symptomatic hypoglycemia, she was admitted to the hospital, where she had new episodes of hypoglycemia. A Chest X ray and scan showed a right pleural tumor that was surgically excised. After surgery the episodes of hypoglycemia subsided. The pathological study of the tumor revealed a solitary fibrous pleural tumor. After 15 months of follow up, the patient is symptom free and without evidence of tumor relapse.

RESUMO

The plasmacytomas tumors are caused by a malignant proliferation of plasma cells. Primary tumors of the sternum are uncommon, being this kind of tumors exceptional. We present the case of a 72 years old man with a sternal plasmacytoma, that after 2 years of receiving radiotherapy treatment, had tumor growth, associated with coronary artery disease. In this case, surgical resection of solitary sternal plasmacytoma was performed associated with coronary artery bypass grafting surgery. The chest wall reconstruction was done with a polypropylene mesh. More than 5 years long-term follow up was completed and the patient is asymptomatic and free of malignant proliferation of plasma cells.


Los plasmocitomas son tumores originados por una proliferación neoplásica de células plasmáticas. Los tumores primarios de esternón son infrecuentes, siendo los plasmocitomas solitarios de esternón excepcionales. Presentamos el caso de un hombre de 72 años con un plasmocitoma esternal que después de 2 años post tratamiento con radioterapia presentó aumento de tamaño tumoral asociado a enfermedad coronaria. Se realizó resección quirúrgica del plasmocitoma solitario del esternón asociada a cirugía de revascularización miocárdica con 4 bypass coronarios. La pared torácica fue reconstituida con una malla de polipropileno. A más de 5 años de seguimiento el paciente se encuentra asintomático cardiovascular y libre proliferación maligna de células plasmáticas.

RESUMO

Introducción: La mediastinitis necrotizante descendente (MND) requiere un manejo precoz y agresivo por su alta morbimortalidad. Objetivo: Describir características de las MND manejadas por nuestros equipo y determinar factores de riesgo de letalidad. Material y Método: Estudio descriptivo retrospectivo. Período enero 1993-junio 2004. Información de base de datos Equipo Cirugía Cardiotorácica y fichas clínicas. Se describe edad, género, características clínicas, tiempos de evolución, etiología, tratamiento quirúrgico, morbimortalidad y evolución. Para determinar factores de riesgo de letalidad se realiza el análisis multivariado de 14 factores pre, intra y postoperatorios, utilizando la prueba de regresión logística, método fordward stepwise. Resultados: 10 casos, todos masculinos. Edad promedio 42,2 años. Síntomas frecuentes: dolor en 8, disnea 7 y fiebre 6. Tiempo de evolución de síntomas-consulta promedio 5,8 días; entre consulta-diagnóstico 3 días; todos se operaron al momento del diagnóstico. El origen fue en 4 casos dental, en 3 otorrinolaringológico y en 3 no precisado. El promedio de cirugías por paciente fue 1,7 con rango 1-3. En 5 se realizó abordaje cervical simultáneo y en 4 casos traqueostomías. No necesitaron ventilación mecánica postoperatoria 9, promedio 16 días. Seis pacientes presentaron complicaciones postoperatorias, la más frecuente una insuficiencia renal aguda y neumonía en 3. Fallecieron 5 en falla orgánica múltiple. Promedio de hospitalización postoperatoria 26,1 días, rango 8-90. En el análisis multivariado se encontró como factor de riesgo de letalidad el número de unidades de hemoderivados en el postoperatorio y la necesidad de transfusión de plasma. Conclusiones: La MND presenta alta morbimortalidad. Para nuestra serie la utilización de hemoderivados en el postoperatorio seria un factor asociado a letalidad.

RESUMO

Introducción: Los tumores cardíacos son infrecuentes, su incidencia va del 0.0017 al 0.28 por ciento siendo de ellos el 75 por ciento benignos. Los más frecuentes son los mixomas de localización auricular. Objetivo: Describir las características de los tumores cardíacos certificados por anatomía patológica. Material y método: Estudio descriptivo-retrospectivo. Período enero 1984-junio 2004. Información obtenida de la base de datos del equipo de Cirugía Cardiotorácica, fichas clínicas y registros de anatomía patológica. Se describe sexo, edad, características clínicas, método diagnóstico, tratamiento quirúrgico, anatomía patológica, evolución y seguimiento. Resultados: Total 10 casos, 8 hombres. Edad promedio 42.7 años. Síntomas cardiovasculares 8 pacientes, 1 asintomático y 1 corresponde a necropsia. Manifestación clínica más frecuente disnea en 7. Cuatro pacientes en capacidad funcional mayor o igual a III al momento del diagnóstico. Principal método diagnóstico: ecocardiograma transtorácico. Se realizó tratamiento quirúrgico en 9 pacientes, en 5 resección y en 4 resección y cierre del defecto residual con parche. En un paciente portador de insuficiencia aórtica, se realizo cirugía de reemplazo valvular aórtico y resección del tumor, todos con circulación extracorpórea. La localización fue en 9 casos auricular, 8 en aurícula izquierda y uno ventricular izquierdo y todos fueron mixomas. Presentaron morbilidad 3 pacientes, un neumotórax, una dehiscencia esternal y un hematoma de la esternotomía. No hubo reoperaciones ni mortalidad. En el seguimiento todos mejoraron su capacidad funcional. Conclusiones: Los tumores cardíacos son infrecuentes, siendo los más habituales los mixomas auriculares izquierdos. Presentan clínica inespecífica y son de baja morbimortalidad operatoria.
