RESUMO

BACKGROUND/OBJECTIVES: To analyze the best noninvasive tests prognosis marker in patients with diabetic foot ulcer (DFU) who underwent endovascular revascularization based on clinical outcomes, such as healing rate, time to heal, and free amputation survival after at least a six-month follow-up. METHODS: A multicentric prospective observational study was performed with 28 participants with ischemic or neuroischemic DFU who came to the participant centers and underwent endovascular revascularization between January 2022 and March 2023. Toe systolic pressure (TP), ankle systolic pressure (AP), the ankle brachial pressure index (ABPI), the toe brachial pressure index (TBPI), transcutaneous pressure of oxygen (TcPO2), and skin perfusion pressure (SPP) were evaluated using PeriFlux 6000 System, Perimed, Sweden, before (Visit 0) and four weeks after revascularization (Visit 1). The primary clinical outcome was an evaluation of the clinical evolution of noninvasive tests comparing Visit 0 and Visit 1, estimating the sensitivity for predicting wound healing of noninvasive tests at six months following initial recruitment. RESULTS: After six months, 71.43% (n = 20) of DFU healed, four patients (14.3%) received major amputations, and one (3.5%) died. The two tests that best predicted wound healing after revascularization according to the ROC curve were TcPO2 and TP with sensitivities of 0.89 and 0.70 for the cut-off points of 24 mmHg and 46 mmHg, respectively. CONCLUSIONS: TcPO2 and TP were the two tests that best predicted wound healing in patients who underwent endovascular revascularization. Clinicians should consider the importance of the evaluation of microcirculation in the healing prognosis of patients with diabetic foot ulcers.

RESUMO

Introducción. En cirugía vascular el modelo tradicional de la consulta médica exigía que el enfermo visitara el centro sanitario al menos en tres ocasiones. En el modelo de consulta de alta resolución, al realizar las exploraciones complementarias, se unifican las tres consultas en una. Objetivo. Plantear el modelo de única consulta en nuestro medio y analizar sus ventajas y desventajas mediante una descripción de los recursos necesarios. Pacientes y métodos. Estudio descriptivo de la actividad de consulta externa de Angiología y Cirugía Vascular en nuestro centro durante el mes de noviembre de 2004. Resultados. Durante ese mes atendimos en consulta a 432 pacientes: 148 nuevos (34,25%) y 284 (65,74%) revisiones. Se realizó alguna prueba diagnóstica al 100% de los pacientes con patología de troncos supraaórticos (TSA), hipertensión arterial /insuficiencia renal y fístula arteriovenosa; al 83% de los enfermos con aneurisma aortoilíaco; al 56% con arteriopatía periférica; y al 41% con insuficiencia venosa. Así, las pruebas complementarias se realizaron en el 40% (59/148) de los pacientes nuevos y en el 58% (165/284) de las revisiones. En todas las consultas se informó a los enfermos del resultado del estudio y del tratamiento necesario, por lo que evitamos 302 consultas sucesivas. El tiempo medio para la realización de un Doppler de miembros inferiores fue de 6 minutos; de un eco-Doppler de TSA, de 14 minutos; de uno abdominal, 9,6 minutos; femoral, 10 minutos; arterial preoperatorio de miembros inferiores, 50 minutos; venoso, 7,4 minutos, y renal, 30 minutos. Conclusiones. La consulta de alta resolución es factible en la mayoría de nuestros pacientes y disminuye el número de revisiones por cada caso


Introduction. In vascular surgery the traditional model of medical clinics required the patient to visit the health care centre on at least three occasions. In the one-stop clinic model, on performing the complementary examinations, the three visits become just one. Aim. To propose the single visit model in our area and to analyse its advantages and disadvantages by means of a description of the resources that would be needed. Patients and methods. We conducted a descriptive study of the activity in the Angiology and Vascular Surgery outpatient department in our centre during November 2004. Results. Throughout that month 432 patients visited: 148 were new cases (34.25%) and 284 (65.74%) were checkups. Diagnostic tests were carried out in 100% of patients with pathologies involving the supra-aortic trunks (SAT), arterial hypertension/renal failure and arteriovenous fistula; in 83% of patients with aortoiliac aneurysms; 56% of those with peripheral arterial disease; and 41% of subjects with venous insufficiency. Complementary tests were performed in 40% (59/148) of new patients and in 58% (165/284) of the checkups. In all visits patients were informed of the results of the study and the treatment they would require, which avoided the need for 302 successive visits. The average time required to perform a Doppler of the lower limbs was 6 minuts; a Doppler ultrasound recording of the SAT was 14 minutes; of the abdomen, 9.6 minutes; femoral, 10 minutes; preoperative arterial of the lower limbs, 50 minutes; venous, 7.4 minutes; and renal, 30 minutes. Conclusions. The one-stop clinic is a feasible proposition with most of our patients and reduces the number of checkups required by each case

RESUMO

Introducción. El stent carotídeo con protección cerebral es una alternativa al tratamiento quirúrgico convencional en los pacientes de alto riesgo. Los sistemas de protección proximal son los únicos que previenen la embolia cerebral antes de cruzar la lesión. Recientemente se ha descrito una nueva técnica de stent carotídeo mediante abordaje cervical con reversión de flujo. Presentamos nuestra experiencia inicial con este procedimiento. Pacientes y métodos. Entre octubre de 2003 y noviembre de 2004 hemos tratado a 11 pacientes de alto riesgo, 9 varones y 2 mujeres, con una media de edad de 80 años (rango: 72-83 años), de los cuales el 91% era sintomático, uno de ellos con oclusión de la carótida interna contralateral. Resultados. Todos los pacientes se intervinieron con anestesia local, sin complicaciones neurológicas ni locales. Todos presentaron buena tolerancia a la reversión del flujo, y sólo hubo una bradicardia durante la dilatación (9%) resuelta con atropina. Todos fueron dados de alta en 48 horas. Durante el seguimiento medio de 11,1 meses (rango: 6-12 meses), un paciente falleció a los 3 meses por infección respiratoria. No hubo ningún evento neurológico. También hubo un paciente con reestenosis asintomática superior al 70%. Conclusiones. El tratamiento de la estenosis carotídea puede realizarse de forma sencilla y segura mediante la implantación de un stent por abordaje cervical con reversión de flujo. Elimina la dificultad de acceso en pacientes con enfermedad aortoilíaca o anatomía desfavorable del cayado, y evita las complicaciones femorales pospunción. Mientras no dispongamos de más datos sobre la efectividad y permeabilidad a largo plazo, preferimos reservar este procedimiento para los pacientes de alto riesgo (AU)


Introduction. Carotid stenting with cerebral protection is an option for the treatment of high-risk patients. Proximal occlusion catheters have the advantage of preventing cerebral embolisms before crossing the plaque. Recently a new transcervical approach with carotid flow reversal has been introduced for carotid artery stenting. We describe our initial experience with this technique. Patients and methods. Between October 2003 and November 2004 we have stented 11 high-risk patients, 9 men and 2 women, mean age 80 years (range: 72-83 years); 91% symptomatic, one of them associated contralateral carotid artery occlusion. Results. All procedures were successfully performed under local anesthesia without neurologic or local complications. Flow reversal was well tolerated in everyone, and one patient had angioplasty-induced bradycardia (9%) treated with atropine. All patients were discharged within 48 hours. During the 11.1 mean follow up (6-12 months) one patient died because of pneumonia. There was not any neurologic event. One patient had an asymptomatic reestenosis higher than 70%. Conclusions. Treatment of carotid stenosis can be accomplished simply and safely using the transcervical carotid artery stenting with flow reversal. It eliminates the problems of access in patients with aortoiliac disease or unfavourable arch anatomy, and avoids the femoral postpuncture complications. We prefer to keep this procedure for high-risk patients until more long-term patency rates are available (AU)

RESUMO

Objetivo. Evaluar la prevalencia de la enfermedad arterial periférica (EAP) en atención primaria (AP), mediante un estudio piloto epidemiológico transversal basado en la medición del índice tobillo-brazo (ITB). Pacientes y métodos. Medición del ITB en pacientes que acuden a la consulta de AP. Criterios de inclusión: mayores de 65 años, o entre 50 y 65 años con factores de riesgo de aterotrombosis. Se han incluido 300 pacientes, cuya media de edad es de 69 años. Un paciente fue excluido por no cumplir los criterios de inclusión. De los 299, el 48% eran varones, y el 66%, mayores de 65 años. El 86% tenía factores de riesgo de aterotrombosis: hipertensión arterial (69%), hipercolesterolemia (50%), diabetes tipo I o II (28%) y consumo de tabaco de más de 15 cigarrillos al día (12%). El 5% tenía antecedentes de enfermedad cerebrovascular, el 13% de enfermedad coronaria y el 8% de EAP. Resultados. El 23% de los 299 pacientes presentó un ITB £ 0,9, es decir, EAP leve/moderada, frente al 77% con un ITB > 0,9. No se identificó ningún paciente con EAP grave (ITB < 0,4). La prevalencia de la EAP era más alta en mayores de 65 años (p < 0,05). El 31% de los ITB < 0,9 se derivó a Cirugía Vascular. Conclusión. La prevalencia de la EAP es del 23% en AP en mayores de 50 años y es más alta en mayores de 65 años (p < 0,05). El ITB es una prueba sencilla al alcance de personal entrenado y constituye el marcador más significativo de cribado de EAP


AIM. To evaluate the prevalence rate of peripheral arterial disease (PAD) in primary care (PC) by means of a cross-sectional epidemiological pilot study based on measurements of the ankle brachial index (ABI). PATIENTS AND METHODS. Measurement of the ABI in patients who visit PC centres. Eligibility criteria: over 65 years of age or between 50 and 65 with risk factors for atherothrombosis. A total of 300 patients were included, their mean age being 69 years. One patient was excluded because he did not satisfy the eligibility criteria. Of the remaining 299, 48% were males. 66% were over 65 years old. 86% had risk factors for atherothrombosis, namely, arterial hypertension (69%); hypercholesterolemia (50%); type 1 or 2 diabetes (28%); smoking more than 15 cigarettes a day (12%). The study showed that 5% of them had a history of cerebrovascular disease, 13% heart disease and 8% PAD. RESULTS. A total of 23% of the 299 patients had an ABI £ 0.9, that is to say mild or moderate PAD, versus 77% with an ABI > 0.9. No patients were found to have severe PAD (ABI < 0.4). The rate of prevalence of PAD was higher in those aged above 65 (p < 0.05). Of the cases of ABI < 0.9, 31% were referred to vascular surgery. CONCLUSION. The prevalence rate of PAD is 23% in PC in patients above the age of 50 and is higher in those over 65 years old (p < 0.05). The ABI is a simple test that can be utilised by trained members of staff and is the most powerful marker in screening for PAD
