RESUMO

Nuevamente, desde el Capítulo de Diagnóstico Vascular de la Sociedad Española de Angiología y Cirugía Vascularnos proponemos la actualización de una guía de diagnóstico. Concretamente, la Guía de estudio de la isquemiade miembros inferiores. Creemos que la elaboración, la difusión y la utilización de guías de todo tipo permitiráuna mayor homogenización en el uso y en la difusión de las técnicas de diagnóstico que utilizamos en nuestroquehacer diario. La homogenización permitirá una mayor fiabilidad y prestigio en estas exploraciones. Por otra parte, la naturaleza de las guías de diagnóstico requiere mucha menos renovación que otro tipo de guíasy de documentos: las exploraciones que configuran nuestro motivo de ser no suelen variar de forma profundaa lo largo del tiempo. Ahora bien, es cierto que las explicaciones pueden darse de otro modo y complementarlas ya existentes, en absoluto obsoletas. Con este espíritu hemos abordado la elaboración de esta actualización. Se ha respetado completamente la guía previa publicada en 2009. Solo nos hemos permitido reescribir, por suimportancia y por su papel como piedra angular en el estudio de la isquemia de miembros inferiores, el capítulodedicado al estudio con ecografía Doppler arterial de las extremidades inferiores, aunque siempre con una visióncomplementaria, no excluyente, a lo ya publicado hace tantos años. El resto de la guía expone tres exploracio-nes emergentes, no tratadas previamente, pues casi no existían, que pueden suponer un avance, una mejora sicabe, en el estudio arterial de las extremidades isquémicas. Se trata del tiempo de aceleración pedal, tema derabiosa actualidad, de la determinación de la presión transcutánea de oxígeno, tan importante en la patologíaisquémica del diabético, y, finalmente, de la angiografía de perfusión, técnica de diagnóstico emergente y coninfinidad de posibilidades, muchas de ellas ni siquiera estudiadas...(AU)


Once again, from the Vascular Diagnosis Chapter of the Spanish Society of Angiology and Vascular Surgery, wepropose to update a diagnostic guide. Specifically, the Lower Limb Ischemia Study Guide. We believe that theelaboration, diffusion, and use of guides of all kinds will allow a greater homogenization in the use and diffusion ofthe diagnostic techniques that we use in our daily work. Homogenization will allow greater reliability and prestigein these explorations. On the other hand, the nature of diagnostic guides requires much less renewal than other types of guides anddocuments: the examinations that make up our reason for being do not usually vary profoundly over time. Now, it istrue that the explanations can be given in another way and complement the existing ones, which are by no meansobsolete. It is in this spirit that we have approached the making of this update. The previous guideline publishedin 2009 has been fully respected. Due to its importance and its role as a cornerstone in the study of lower limbischemia, we have rewritten the chapter dedicated to the study with arterial Doppler ultrasound of the lower limbs,although always with a complementary vision, not exclusive, to what was already published so many years ago. The rest of the guide exposes three emerging explorations, not previously treated, since they hardly existed, whichmay represent an advance, an improvement, if possible, in the arterial study of ischemic extremities. It deals withpedal acceleration time, a high topic, with the determination of transcutaneous oxygen pressure, so important inthe ischemic pathology of diabetics, and, finally, with perfusion angiography, an emerging diagnostic techniquewith infinite possibilities, many of them not even studied. To carry out this work we have turned to proven professionals in each treated section. We believe that the guidewill help to better carry out our daily explorations in ischemia of the lower limbs.(AU)

RESUMO

OBJETIVO: Analizar el coste-efectividad de la aplicación de algoritmos diagnósticos en pacientes con sospecha de un primer episodio de trombosis venosa profunda (TVP) en la atención primaria, en comparación con la derivación sistemática a centros especializados. Diseño: Estudio observacional, transversal y analítico. EMPLAZAMIENTO: Pacientes seleccionados en urgencias hospitalarias derivados desde la atención primaria para completar estudio y diagnóstico. Participantes: Se reclutó a 138 candidatos con clínica compatible con un primer episodio de TVP; 22 fueron excluidos (sin informe de derivación, clínica de más de 30 días, anticoagulados y TVP previa), incluyéndose finalmente a 116 pacientes, un 61% mujeres, de 71 años edad media. Mediciones principales: Variables de las escalas de probabilidad clínica de Wells y Oudega, dímero-D (portátil y hospitalario), ecografía-Doppler y costes directos generados por los 3 circuitos analizados: derivación sistemática de todos los pacientes, derivación según escala de Oudega o de Wells. RESULTADOS: En el 18,9% se confirmó el diagnóstico de TVP. Las 2 escalas de probabilidad clínica presentaron una sensibilidad del 100% (IC del 95%: 85,1-100) y una especificidad alrededor del 40%. Con la aplicación de las escalas, se hubiesen podido evitar con total seguridad un tercio de las derivaciones a urgencias hospitalarias (p < 0,001) y se hubieran podido disminuir los costes del proceso diagnóstico en 8.620 € según Oudega y 9.741 € según Wells, por cada 100 pacientes atendidos. CONCLUSIONES: La aplicación de algoritmos diagnósticos en las sospechas de TVP permitiría al médico de atención primaria una orientación más resolutiva y coste-efectiva del proceso diagnóstico


OBJECTIVE: To analyse the cost effectiveness of the application of diagnostic algorithms in patients with a first episode of suspected deep vein thrombosis (DVT) in Primary Care compared with systematic referral to specialised centres. DESIGN: Observational, cross-sectional, analytical study. Location: Patients from hospital emergency rooms referred from Primary Care to complete clinical evaluation and diagnosis. Participants: A total of 138 patients with symptoms of a first episode of DVT were recruited; 22 were excluded (no Primary Care report, symptoms for more than 30 days, anticoagulant treatment, and previous DVT). Of the 116 patients finally included, 61% women and the mean age was 71 years. Main measurements: Variables from the Wells and Oudega clinical probability scales, D-dimer (portable and hospital), Doppler ultrasound, and direct costs generated by the three algorithms analysed: all patients were referred systematically, referral according to Wells and Oudega scale. RESULTS: DVT was confirmed in 18.9%. The two clinical probability scales showed a sensitivity of 100% (95% CI: 85.1 to 100) and a specificity of about 40%. With the application of the scales, one third of all referrals to hospital emergency rooms could have been avoided (P < .001). The diagnostic cost could have been reduced by € 8,620 according to Oudega and € 9,741 according to Wells, per 100 patients visited. CONCLUSION: The application of diagnostic algorithms when a DVT is suspected could lead to better diagnostic management by physicians, and a more cost effective process
