ABSTRACT

BACKGROUND AND OBJECTIVE: Doctors provide patients the information in written form by informed consents (IC), being the readability essential in the quality of care. The primary endpoint was to analyze the readability of IC published by the Chapter of Endovascular Surgery (CCEV) of the Spanish Society of Angiology and Vascular Surgery (SEACV) in 2019, and its evolution to those published by the SEACV in 2007. MATERIALS AND METHODS: The ICs were organized by sectors and we obtained the following parameters: syllables, words, phrases, average words/phrases and syllables/words, Flesch, Flesch-Szigriszt, Fernández-Huerta and Gunning-Fog indexes, as well as the grade on the Inflesz scale. RESULTS: The Flesch index classified the CCEV consents as very difficult, and the Gunning-Fog index reflected a readability equivalent to university texts. The Flesch-Szigriszt, Fernández-Huerta indexes and Inflesz scale classified them as normal. The ICs with less readability were those referring to supra-aortic trunks (SAT) and miscellaneous in the Fernández-Huerta (P<.020 and P<.05, respectively) and Flesch-Szigriszt (P<.05) indexes. However, ICs regarding venous pathology showed a better readability in this indexes (P<.006). CCEV consents were significantly longer than SEACV consents (P=.021). In addition, there was a decrease over time in the mean value of the Fernandez-Huerta and Flesch-Szigriszt indexes (P=.002). CONCLUSIONS: Although CCEV consents had a normal readability, it has been observed a decrease in the readability indexes compared to those published in 2007 by the SEACV. In addition the length and content of the ICs should be reviewed, especially those relating to SAT and miscellaneous.

ABSTRACT

ANTECEDENTES Y OBJETIVO: En las últimas dos décadas, las técnicas endovasculares han supuesto un avance sin precedentes en el tratamiento quirúrgico de las enfermedades vasculares. Sin embargo, dichas técnicas suponen una exposición a radiación ionizante tanto para los pacientes como para el equipo quirúrgico. Algunos estudios sugieren la realización de análisis citogenéticos de manera complementaria a la dosimetría habitual. No obstante, hasta la fecha los datos sobre las alteraciones genéticas producidas por la exposición crónica a dosis bajas de radiación son escasos. El presente estudio es parte del Iradient Study (Ionizing RADiation in ENdovascular Treatments) de inestabilidad genómica en angioIólogos y cirujanos vasculares (PI-18-967). El objetivo principal fue validar el análisis genómico mediante tinción de bandas GTG (G-banding by Trypsin with Giemsa) como marcador de alteraciones genómicas en angiólogos y cirujanos vasculares expuestos de manera crónica a dosis bajas de radiación ionizante. Material y Métodos. Estudio nacional, observacional y transversal de casos y controles de aneuploidias en angiólogos y cirujanos vasculares expuestos de manera crónica a bajas dosis de radiación ionizante versus controles no expuestos a radiación ionizante. Las variables categóricas se analizaron mediante el Test exacto de Fisher siendo que las variables cuantitativas se analizaron prueba de Kruskall-Wallis o U de Mann-Whitney. RESULTADOS: Se incluyeron 24 sujetos como casos, provenientes de 13 centros distintos, y 4 sujetos sanos como controles. El tiempo de exposición medio a radiación ionizante del grupo de casos fue 18.9 ± 3.2 años. No se objetivó correlación entre la edad y el tiempo de exposición a radiación ionizante y la presencia de aneuploidias. En el estudio de tinción de bandas GTG no se observaron diferencias significativas en cuanto al porcentaje de metafases hipodiploides (controles 27.06 ± 16.00% versus casos 18.80 ± 8.59%, p = 0.144), porcentaje de metafases hiperdiploides (controles 3.58 ± 3.55% versus casos 1.48 ± 2.53%, p = 0.082) ni en cuanto al porcentaje de alteraciones estructurales (controles 3.97 ± 3.43% versus casos 10.63 ± 8.89%, p = 0.126). CONCLUSIONES: La edad y el tiempo de exposición a radiación ionizante no se relacionan con un aumento significativo de aneuploidias mediante técnica de tinción de bandas GTG. Ni tipo de actividad endovascular realizada, ni el tipo de quirófano utilizado suponen un aumento de inestabilidad genómica según el análisis de tinción de bandas GTG. Según los resultados del presente estudio no se valida el análisis de tinción de bandas GTG como marcador de inestabilidad genómica en angiólogos y cirujanos vasculares expuestos de manera crónica a radiación ionizante


BACKGROUND AND OBJECTIVES: The past two decades have witnessed the development and growth of the endovascular techniques, however, this new technology is not exempt from risks, since its use requires an ionizing radiation exposure to both patients and surgeons. In this context, the long-term repercussion of this type of chronic exposure to low dose ionizing radiation of the vascular sur-geons is still unknown. Some studies suggest the use of routine cytogenetic analysis to complement the conventional dosimetry, yet he real genomic effects of chronic low dose ionizing radiation exposure is still unclear and an ideal biodosimetry marker hasn't been described. The present study is part of the Iradient Study (Ionizing RADiation in ENdovascular Treatments) of genomic instability in vascular surgeons (PI-18-967). In this setting, the main goal of the present study was to validate the cytogenetic GTG-banding (G-banding by Trypsin with Giemsa) technique as a biomarker of genomic instability associated to the chronic low dose exposure to ionizing radiation of vascular surgeons. MATERIAL AND METHODS: National, observational and transversal case control study of ge-nomic instability among vascular surgeons chronically exposed to low dose ionizing radiation compared to healthy control patients with no previous history of radiation exposure. The statistical analysis of the categorical variables was performed using the Fisher exact test and the quantitative variables were studies using the Kruskall-Wallis or U de Mann-Whitney tests. RESULTS: 24 subjects from 13 different hospitals were included as cases, and 4 healthy non-exposed subjects were included as controls. There were no meaningful differences in terms age and demographical variables between groups. In the case group the mean exposure duration was 18.93±3.2 years. There was no significant correlation between age and duration of exposure and the presence of aneuploidies in the GTG-banding analysis. In the GTG-banding chromosome study there were no significant differences between groups in terms of the rate of hipodiploid metaphases (controls 27.06 ± 16.00% versus cases 18.80 ± 8.59%, p = 0.144), rate of hiperdiploid metapha-ses (controls 3.58 ± 3.55% versus cass 1.48 ± 2.53%, p = 0.082) or rate of structural chromosome aberrations (controls 3.97 ± 3.43% versus cases 10.63 ± 8.89%, p = 0.126). CONCLUSIONS: Nor the age or the duration of exposure to ionizing radiation were associated with a higher rate of chromosomal aberrations with the GTG-banding study. Also, the type of endovascular activity and the type of surgical room weren't associated with an increase in the genomic instability in the GTG-banding study. The present results do not allow the validation of the GTG-banding analysis as a biomarker of long term exposure to low dose radiation during endovascular procedures

ABSTRACT

La infección por SARS-COV-2 se ha convertido en una emergencia sanitaria internacional. Junto con la infección respiratoria, se pueden presentar complicaciones derivadas de un estado de hipercoagulabilidad, ensombreciendo el pronóstico. Se presenta el caso clínico de un paciente con neumonía vírica por SARS-COV-2, en el que se produce una isquemia arterial bilateral de extremidades inferiores


SARS-COV-2 infection has become an international health emergency. Apart from the respiratory disease, complications arising from an hypercoagulable state may occur, overshadowing the prognostic. The clinical case of a patient with SARS-COV-2 viral pneumonia is presented, in which bilateral arterial ischemia of the lower extremities occurs

ABSTRACT

Objetivo: Evaluar el efecto anatómico a largo plazo de la reparación endovascular de la aorta torácica (TEVAR) en disecciones tipo B complicadas en comparación con segmentos no tratados de la aorta. Material y métodos: Entre enero de 2008 y septiembre de 2015, 18 pacientes con disección de aorta complicada tipo B se trataron mediante TEVAR con al menos un año de seguimiento en imágenes. Se realizaron angio-TC a los 3, 6, 12 meses y anualmente (media 25,25 ± 22,9 meses) a partir de entonces y se compararon con las angio-TC preoperatorias. Se registraron las medidas de mayor diámetro de la aorta, de la luz verdadera y de la luz falsa (LF) a nivel del segmento stentado, así como en segmentos no tratados de la aorta torácica y de la aorta abdominal supracelíaca. El análisis estadístico se realizó con un análisis de la varianza de efecto mixto para medidas repetidas. Resultados: La edad media fue de 57,67 años y un 88,9% eran hombres. La indicación de TEVAR fue: 5,6% síndrome de malperfusión, 27,8% hipertensión refractaria, 11,1% diámetro > 40mm, 50% dolor persistente y 5,6% hematoma periaórtico. El mayor diámetro de la aorta permaneció estable durante el seguimiento (p = 0,230), el diámetro de la luz verdadera en el segmento tratado aumentó (p = 0,005), y el diámetro de la LF disminuyó (p = 0,020). La trombosis completa de la LF se consiguió mediante la liberación de coils en aquellos casos con permeabilidad de LF y aumento del mayor diámetro de la aorta durante el seguimiento. Conclusiones: El tratamiento mediante TEVAR de disecciones agudas de aorta promueve la remodelación a largo plazo de los segmentos tratados en detrimento del diámetro de la LF en comparación con segmentos no tratados de la aorta. El uso de coils asocia trombosis a largo plazo de la LF y la estabilización del diámetro aórtico (AU)


Objective: To evaluate the long-term anatomical effect of thoracic endovascular aortic repair (TEVAR) in acute type B aortic dissection in comparison with untreated segments of the aorta. Material and methods. A total of 18 patients with complicated type B aortic dissection were treated with TEVAR between January 2008 and September 2015, and had over one-year follow-up imaging. Computed tomography angiograms obtained at 3, 6, and 12 months and long-term (mean 25.25 ± 22.9 months) were compared with baseline scans. The largest diameters of the stented thoracic aorta, stented true lumen, and stented false lumen (FL) were recorded at each time point, as well as the values in the unstented distal thoracic aorta and the abdominal aorta (supracoeliac). Changes over time were evaluated by a mixed effect analysis of variance model of repeated measurements. Results: The mean age of the patients was 57.67 years, and 88.9% were male. Indications for TEVAR were: 5.6% malperfusion, 27.8% refractory hypertension, 11.1% diameter > 40 mm, 50% persistent pain, and 5.6% peri-aortic haematoma. The maximum diameter of the stented thoracic aorta was stable (P = .230), the diameter of the stented true lumen increased (P = .005), and the diameter of the stented FL decreased (P = .020). Complete FL obliteration was achieved more significantly by liberating coils in those cases with residual patency of the FL and an increase in aortic diameter during follow-up. Conclusions: TEVAR of acute aortic dissection promotes long-term remodelling across the stented segment, with a significant long-term decrease of false lumen diameter compared to untreated segments of the aorta. The use of coils is significantly associated with long-term obliteration of the FL and stabilisation of aortic diameter (AU)
