Caracterización de las variantes anatómicas de las venas pulmonares en pacientes candidatos a aislamiento de venas pulmonares en Colombia

Introducción y objetivos: El conocimiento de la anatomía de las venas pulmonares y de la aurícula izquierda es fundamental para la planeación y prevención de posibles complicaciones durante la ablación de las venas pulmonares, procedimiento realizado para el manejo de la fibrilación auricular. Este estudio pretende caracterizar la anatomía (tamaño y forma) de las venas pulmonares y determinar las variantes anatómicas más comunes de las mismas. Métodos: Se analizaron 277 estudios de angioresonancia tridimensional y tomografía computarizada realizados previo al procedimiento de aislamiento de venas pulmonares. Se evaluaron los diámetros de la aurícula izquierda, de los ostia de las venas pulmonares y se determinaron la presencia de venas pulmonares comunes, accesorias y ramificaciones tempranas. Resultados: 75% de nuestros pacientes presentaron la anatomía normal de dos venas pulmonares derechas y dos izquierdas. En un 10,1% de los casos se encontraron venas supernumerarias y en un 11,2% se encontró un tronco común. En un 61% de los pacientes se encontraron ramas ostiales, las cuales en un 39,4% de los casos se presentaron en la vena pulmonar inferior derecha. Conclusiones: La evaluación de la morfología de la aurícula derecha y las venas pulmonares por medio de angioresonancia o tomografía computarizada, es necesaria para la realización de ablación por radiofrecuencia dada la alta frecuencia de variantes anatómicas y presencia de ramas ostiales.

Calidad de vida en salud en pacientes con insuficiencia venosa mixta luego de varicosafenectomia

INTRODUCCIÓN: Estudios demuestran la mejoría de la insuficiencia venosa profunda luego de realizar varicosafenectomía, la amplia brecha entre resultados positivos (30-70%) deja en cuestionamiento la realización de cirugía para esta condición. Sin embargo, la mejoría en la calidad de vida en el postoperatorio pudiera ser otra razón para realizar varicosafenectomía en pacientes con insuficiencia venosa mixta. METODOLOGÍA: Se realizó un estudio de corte transversal en pacientes con diagnóstico de insuficiencia venosa mixta llevados a varicosafenectomía. En el periodo post operatorio se practicaron encuestas de calidad de vida de tipo genérico y específico realizando un análisis uni y bivariado de dicha información mediante el programa Stata. RESULTADOS: Se obtuvieron 60 pacientes, al practicar las encuestas de calidad de vida se encontraron datos estadísticamente significativos (p 0.04) en la percepción de su salud con respecto al año anterior y escalas de las encuestas referentes a estados generales de salud como función física y vitalidad. Adicionalmente, se encontró mejoría en el estado de la piel y no se evidenciaron complicaciones tales como Tromboembolismo pulmonar o Trombosis venosa profunda. CONCLUSIONES: Los resultados del presente estudio demuestran que la mayor parte de los pacientes luego de varicosafenectomía tienen una buena percepción de calidad de vida en salud, reflejada en las altas puntuaciones en la mayoría de las escalas de la SF-36, y los bajos puntajes en el cuestionario específico de insuficiencia venosa. La mejoría en la piel de la mayoría de los pacientes en el periodo postoperatorio y la mínima presencia de complicaciones como TEP o TVP hacen que la remoción de los troncos safenos incompetentes en este tipo de pacientes pueda establecerse como indicación quirúrgica

Effects of pulmonary rehabilitation program in a patient with severe asthma diagnosis

Objective: to present the effectiveness of pulmonary rehabilitation programs in the treatmentof a patient with asthma, this is the case of a young Caucasian girl —17 years old— with severe asthma diagnosis, with symptoms since she was eight years old, 10th grade student. Method: She was referred to the program of Pulmonary Rehabilitation after three hospitalizations during the last year due to asthmatic crises, dyspnoea in activities of daily living, and intolerance to physical exercise. In the initial evaluation, a patient with non-controlled asthma was found; she was receiving short-acting medication admitting that she was not complying with regular use and with a prescribed dose of the pharmacological treatment and that she ignored the importance of this commitment for optimal evolution. The patient expressed concern about the progressive deterioration at her respiratory and functional level during the last year and her fear and anxiety for not being able to breathe during activities befitting her age. Results: One month after receiving bronchodilators and long-acting steroids permanently and complying with recommendations about regular use and adequate inhalatory technique, the patient was included in a three-times a-week program of pulmonary rehabilitation during eight weeks for upper and lower extremity endurance and resistance training. Conclusion: This intervention showed significant changes in the patient at functional level and a greater social participation.

Quality of life and Chronic Obstructive Pulmonary Disease

The Chronic Obstructive Pulmonary Disease (COPD) has a progressive and irreversible character and it’s associated to the triad of dyspnea, exercise limitation and the evident deterioration of quality of life. In the United States the prevalence of COPD in adult population is approximately of 6% in men, and 1 to 3% in women and it’s the fourth cause of mortality by no transmissible chronic diseases. In 1993, the National Health Interview Surgery considered that 12 millions of Americans suffer from chronic bronchitis and 2 million had emphysema. These two affections are responsible for more than 13% of the hospitalizations. As this affection progresses, patients experience a diminution in quality of life related to health (CVRS), their capacity to work get worse and their participation in physical and social activities reduces. Nevertheless, it has been confirmed that the isolated evaluation of COPD seriousness, defined by the reduction of the Forced Expiratory Volume in the First Second (FEV1), does not provide enough information to know the health state perceived by the patients. The fact that the CVRS is the result of the interaction of multiple physical, psychological and social factors, unique for each individual, can explain this finding. This paper is a general and updated approach to the integral handling of patients with COPD, and it discusses the concept of quality of life, related to health improvement.

Description and analysis of pulmonary rehabilitation care programs current state in four cities of Colombia

Purpose: there are many studies reporting the benefits of pulmonary rehabilitation, but few of them exhibit the behavior and activities of these services. This article presents the characteristics of services, parts management and training level of team members, in addition to the variables or instruments used to measure the effectiveness and impact in these programs. Method: it was made a cross sectional convenience sample which included seven pulmonary rehabilitation services in four Colombian cities (Bogotá, Medellín, Manizales and Cali), selected by the coverage, for having at least one year of experience and for being formally established and recognized nationwide. The interdisciplinary team of each service answered a survey that was validated through a pilot test and expert consensus. Participation was voluntary. Results: labor onset pulmonary rehabilitation services correspond to an average of a decade, with COPD and asthma pathologies of attention. The programs are characterized by an outpatient treatment with an average duration of eight to twelve weeks, with a frequency of an hour three times a week. Also, the director of the service is regularly a pulmonologist and the coordinator a physiotherapist (57.14%). The posgradual training of these professionals is notable, and they report to have procedural, administrative and communicative skills, but qualify regular there research skills. The physical and technological resources are well tested. 71.42% have done impact studies, but only 28.57% have been published. All have in common training in upper limbs, lower limbs, respiratory muscles, counseling, functional assessment and quality of life. The effectiveness and impact of programs is measured by the walking test, quality of life questionnaires and activities of daily living.
