RESUMO
OBJETIVO: Analizar las diferencias según el sexo en el perfil clínico de riesgo de los pacientes amputados de miembro inferior por causa no traumática. MÉTODO: Estudio retrospectivo descriptivo con 697 pacientes amputados de miembro inferior por causa no traumática, en un Servicio de Angiología y Cirugía Vascular, durante un periodo de 5 años y divididos en función del sexo. Se analizaron variables demográficas (edad) y clínicas (causa, comorbilidad, factores de riesgo cardiovascular y nivel de amputación). RESULTADOS: La edad media (± desviación estándar) de las mujeres fue mayor (75.3 ± 12 frente a 68.9 ± 11 años; p < 0.001) y ellas presentaron mayor frecuencia de factores de riesgo cardiovascular concomitantes, tales como diabetes, hipertensión y obesidad, que los varones, mientras que ellos presentaron mayor frecuencia de tabaquismo. No hubo diferencia significativa entre sexos respecto a la distribución de las causas de amputación, siendo la principal causa la isquémica, destacando la arteriosclerosis. Las mujeres presentaron mayor frecuencia y predisposición para un nivel de amputación mayor. CONCLUSIONES: En nuestro estudio, las mujeres presentaron un perfil de riesgo cardiovascular más desfavorable y el sexo femenino fue un predictor independiente de amputación mayor de miembro inferior por causa no traumática. OBJECTIVES: To analyse the possible gender differences within the clinical risk profile of lower-limb amputee patients who had a non-traumatic amputation. METHOD: A retrospective study with 697 lower-limb amputee patients, classified according to their gender, has been conducted at the Angiology and Vascular Surgery Department for 5 years. The variables considered were demographic variables (age and gender) and clinic variables (cause of the amputation, comorbidity, cardiovascular risk factors and the amputation level). RESULTS: Regarding to the results, the average of women was older than men (75.3 ± 12 vs. 68.9 ± 11 years; p < 0.001), showing an increasing frequency to concomitant cardiovascular risk factors, such as diabetes, hypertension, and obesity. However, men present a higher frequency to smoking. There were no gender differences in the main cause of the amputation, the ischemic cause, being notably into this cause the subgroup of arteriosclerosis cause. Women showed a higher frequency and predisposition for major amputation. CONCLUSIONS: This study showed that women had a more unfavorable cardiovascular risk profile than men, being the female gender an independent predictor to a major lower-limb amputation with non-traumatic amputation.

OBJECTIVE: The International Commission on Radiological Protection (ICRP) has highlighted the large number of medical specialties using fluoroscopy outside imaging departments without programmes of radiation protection (RP) for patients and staff. Vascular surgery is one of these specialties and endovascular aneurysm repair (EVAR) is one of the most challenging procedures requiring RP guidance and optimisation actions. The recent European Directive on Basic Safety Standards requires the use and regular update of diagnostic reference levels (DRL) for interventional procedures. The objective of the study was to know the doses of patients undergoing EVAR with mobile Xray systems and with hybrid rooms (fixed Xray systems), to obtain national DRLs and suggest optimisation actions. METHODS: The Spanish Chapter of Endovascular Surgery launched a national survey that involved hospitals for 10 autonomous communities representing the 77% of the Spanish population (46.7 million inhabitants). Patient dose values from mobile Xray systems were available from nine hospitals (sample of 165 EVAR procedures) and data from hybrid rooms, from seven hospitals, with dosimetric data from 123 procedures. The initial national DRLs have been obtained, as the third quartile of the median values from the different centres involved in the survey. RESULTS: The proposed national DRLs are 278 Gy cm2 for hybrid rooms and 87 Gy cm2 for mobile Xray systems, and for cumulative air kerma (cumulative AK) at the patient entrance reference point, 1403 mGy for hybrid rooms, and 292 mGy for mobile systems. CONCLUSION: An audit of patient doses for EVAR procedures to identify optimised imaging protocol strategies is needed. It is also appropriate to evaluate the diagnostic information required for EVAR procedures. The increase by a factor of 3.2 (for kerma area product) and 4.8 (for cumulative AK) in the DRLs needs to be justified when the procedures are performed in the hybrid rooms rather than with mobile Xray systems.
