RESUMO

Abstract: Introduction: Multiple vascular compression aimed for transradial access have been developed. We aimed to compare the time required to achieve hemostasis in three different radial vascular compression devices. Methods: ST and non-ST elevation MI, unstable and stable angina as well as diagnostic coronary angiograms patients with transradial vascular access (TVA) in 2 centers were enrolled between June 2010-November 2010. Patients were divided according the TVA compression device (TAVCD) used. Group I received TR Band(tm) (Terumo, Tokyo, Japan), Group II received Neptuno(tm) (Biotronik, Berlin, Deutschland) and Group III received Finale(tm) (Merit Medical, South Jordan, UT).Patients were evaluated immediately after TVACD implantation and 24 hour post-procedure follow up. Results: 60 patients were enrolled in this observational study (Group I = 22 patients; Group II = 18; Group III = 20). All patients demonstrated evidence of radial pulse after hemostasis. 28% developed a superficial hematoma (Group I, 31%; Group II, 30%; Group III, 22%). Pain at the access site was uncommon among patients in both immediate and follow-up evaluations, however, 3% (Group I and II) presented paresthesia immediately following the procedure that resolved by the 24-hour evaluation. Conclusion: In our study, all three evaluated radial compression devices successfully achieved hemostasis regardless of the slight alterations of mechanism, yet similarity in aim of non-occlusive compression. Group I (TR band) had a slight increase in compression time recorded but all groups required an approximate three hours to display no evidence of bleeding. None of the patients in the study presented major vascular complications. We consider that further investigation of radial compression devices as compared to manual compression are necessary to evaluate their advantages and may further simplify the procedure


Resumen: Introducción: Múltiples dispositivos de compresión vascular para el acceso radial han sido desarrollados. Nuestro objetivo es comparar el tiempo requerido para lograr la hemostasis con tres diferentes dispositivos de compresión vascular radial. Métodos: Pacientes de angiografía coronaria de diagnóstico, con elevación y no elevación del ST, con angina de pecho inestable y estable, así como pacientes con acceso vascular radial (AVR) en dos centros, fueron incluidos entre junio y noviembre de 2010. Los pacientes fueron divididos según el dispositivo de compresión AVR (DCAVR) usado. Al Grupo I se le dio el TR Band(tm) (Terumo, Tokio, Japón), el Grupo II recibió el Neptuno(tm) (Biotronik, Berlín, Alemania) y el grupo III recibió el Final(tm) (Merit Medica, South Jordan, UT). Los pacientes fueron evaluados inmediatamente después de la implantación del DCAVR y a las 24 horas de postprocedimiento para seguimiento. Resultados: 60 pacientes fueron incluidos en este estudio observacional (Grupo I = 22 pacientes; Grupo II = 18; Grupo III = 20). Todos los pacientes mostraron evidencia de pulso radial después de la hemostasis. 28% desarrolló un hematoma superficial (Grupo I, 31%; Grupo II, 30%; Grupo III, 22%). El dolor en el sitio de acceso fue poco común entre los pacientes de los dos evaluaciones inmediatas y de seguimiento, sin embargo, el 3% (Grupo I y II) presentó parestesias inmediatamente después del procedimiento que se resolvieron para la evaluación de 24 horas. Conclusión: En nuestro estudio, los tres dispositivos de compresión radiales evaluados lograron con éxito la hemostasis sin importar las pequeñas variaciones del mecanismo, dando resultados similares en el objetivo de la compresión no oclusiva. Grupo I (Banda TR) tuvo un ligero aumento en el tiempo de compresión registrado pero todos los grupos requieren un tiempo aproximado de tres horas para mostrar ninguna evidencia de sangrado. Ninguno de los pacientes en el estudio presentó mayores complicaciones vasculares. Consideramos necesario hacer investigación adicional de los dispositivos de compresión radiales, en comparación con la compresión manual para evaluar sus ventajas y poder simplificar aún más el procedimiento.

RESUMO

INTRODUCTION: Catheter-based renal sympathetic denervation is an emerging therapy for resistant hypertension (RHTN) patients, resulting in a significant blood pressure reduction. The presence of accessory renal arteries and anomalous branching patterns are reported in approximately 20-27 % of patients. However, accessory renal arteries, when smaller than 4 mm in diameter, they are out of the inclusion criteria for renal denervation therapy. For this reason patients with evidence of accessory renal arteries have been excluded in previous clinical trials. Recent data suggest that accessory renal arteries may play an important role in non-response therapy when they do not receive renal denervation treatment. CASE REPORT: In this report, we present the outcome of a patient with resistant hypertension and an anomalous right renal artery, having undergone denervation of both principal and accessory renal arteries. The renal ablation by radiofrequency energy of a distant accessory renal artery resulted in a safe procedure with no clinical complications. CONCLUSION: Consistent with literature the RDN of all, main and accessory renal arteries, was effective in decreasing patient blood pressure while decreasing the need for antihypertensive medication.
