Carotid Endarterectomy with routine carotid stump pressure measurement, intraoperative hemodynamic management and selective use of shunt Introduction: During carotid endarterectomy (CEA) clamping cerebral perfusion is maintained by contralateral circulation through the Circle of Willis and it is correlated to the stump pressure (SP). If it is below 50 mmHg there is risk of stroke due to hypoperfusion and a shunt must be used, but systemic blood pressure can be temporarily elevated making the use of shunt unnecessary. Aim: Results of CEA with SP measurement to evaluate cerebral perfusion in cross-clamped hemisphere and hemodynamic intraoperative management reducing the use of shunt. Material and Methods: Retrospective study of CEAs performed in 73 patients under general anaesthesia with SP measurement, hemodynamic management and selective use of shunt. Demographics, clinical and perioperative morbimortality variables were analized. Results: 73 patients, average age 71.1 years, 69.9% symptomatic. In 54 patients SP was above 50 mmHg and shunt was not used, in 19 SP was below 50 mmHg, it was elevated through intraoperative hemodynamic management and shunt was not needed. In only 3 cases SP did not reach 50 mmHg and a Pruitt-Inahara shunt was used. Two patients presented postoperative transient central neurological deficit and 2 died due to myocardial infarction. Conclusion: CEA with SP measurement and hemodynamic management reduced the use of carotid shunting and it was a safe procedure to treat patients with severe carotid stenosis who need surgical intervention.
Objective: To evaluate short and midterm results after endovenous radiofrequency obliteration for treatment of saphenous reflux. Material and Method: Review and updated follow-up of a clinical series of patients after endovenous radiofrequency obliteration of insufficient saphenous trunks at the Hospital Dr. Eduardo Pereira, Valparaíso. Diagnosis was based on clinical parameters and color doppler ultrasonography. A preoperative and postoperative quality of life questionnaire was executed. Results: 77 patients (57 female) with an average age 58.3 years (23-83) and a mean follow-up time of 13.6 months. Patients consulted for symptomatic primary varicose veins of one lower extremity (49) or both (28) with 105 extremities. According to CEAP classification there were C2:84, C3:1, C4:9, C5:4 and C6:7. There were no C0 or C1 extremities. Superficial tributaries of more than 3 mm diameter were removed using Muller's method in all extremities. Furthermore, in some patients procedures were performed as complementary treatments: perforating veins ligation, skin grafting of ulcers or cutaneous-aponeurotic resection and deferred skin graft. A color doppler ultrasonography was performed one month later observing proper saphenous vein obliteration in 99% of cases and 94% at 6-months follow-up. There were no signs of deep vein thrombosis in all patients. The quality of life questionnaire revealed symptomatic relief and surgical satisfaction in the majority of patients. Conclusion: Endovascular radiofrequency obliteration for treatment of saphenous reflux is an effective method for the short and mid terms and can be done alongside other procedure. Key words: radiofrecuency; saphenous vein. ResumenObjetivo: Evaluar los resultados iniciales y en el mediano plazo del tratamiento con radiofrecuencia (RF) de la Insuficiencia Venosa Superficial (IVS) de las extremidades inferiores. Material y Método: Serie de pacientes operados en el Hospital Dr. Eduardo Pereira, Valparaíso por IVS con tratamiento de los troncos safenos insuficientes mediante ablación RF. El diagnóstico fue clínico y mediante eco-doppler color. Se efectuó un cuestionario de calidad de vida en el pre y posoperatorio. Resultados: 77 pacientes (57 mujeres), edad promedio de 58,3 años (23-83) y un seguimiento promedio de 13,6 meses. Los pacientes consultaron por várices primarias sintomáticas de una extremidad inferior (49) o ambas (28) con 105 extremidades, clasificación CEAP C2:84, C3:1, C4:9, C5:4, y C6:7. No hubo extremidades C0 o C1. Se agregó extirpación de tributarias varicosas superficiales mayores de 3 mm de diámetro con gancho en todas las extremidades. Además, en algunos pacientes se realizó ligadura directa de venas perforantes, injerto de úlceras, o resección cutáneo-aponeurótica e injerto diferido como tratamientos complementarios. Se realizó controles con eco-doppler color observando una correcta ablación ecográfica de la vena safena en un 99% a un mes y 94% a los 6 meses de seguimiento. Hubo ausencia de trombosis venosa profunda en todos los pacientes. El ...
Introducción: La embolización de arteria renal (EAR) es un procedimiento percutáneo que ocluye la arteria renal, con la consecuente isquemia del territorio vascular. Sus indicaciones más comunes son la hematuria y el manejo paliativo en cáncer renal metastásico. A pesar del desarrollo técnico y de la experiencia progresiva, los estudios incluyen un número reducido de pacientes y en nuestro país se revisan casos aislados. Objetivo: Describir la experiencia en el Servicio de Salud Valparaíso San Antonio y revisar la literatura existente. Material y Método: Realizamos un estudio descriptivo de los pacientes sometidos a EAR por anemia severa secundaria a hematuria, durante los años 2012 a 2020. Posteriormente, realizamos una revisión de la literatura en PubMed, hasta abril de 2020. Resultados: Incluimos 9 pacientes, 6 (66,7%) hombres y 3 (33,3%) mujeres. La mediana de edad fue de 69 años (RIC=18). La principal causa de la hematuria fue cáncer renal avanzado (7 pacientes). No hubo complicaciones, y se logró éxito clínico en todos los pacientes. Nuestra búsqueda de literatura arrojó 571 referencias y 24 cumplieron con nuestros criterios de elegibilidad. La edad de los pacientes y las causas subyacentes de hematuria fueron variadas. La menor tasa de éxito clínico fue de 65%, sin embargo, 15 estudios (62,5%) reportaron un éxito igual o mayor al 90%. Seis estudios reportaron más de un 10% de pacientes con alguna complicación. Conclusión: Nuestros resultados y la evidencia revisada muestran que la EAR parece ser segura y eficaz en el manejo de anemia severa secundaria a hematuria.
