Cambios de flujo en las venas yugulares internas tras cirugía oncológica cervical no ganglionar / Blood flow change in, the internal jugular veins after oncological neck surgery without lymph node dissection

RESUMEN

Para evaluar la influencia de la cirugía cervical no ganglionar sobre la permeabilidad y el flujo de las venas yugulares internas (M), se realizó un estudio prospectivo. Fueron evaluadas diez VYI en 8 pacientes oncológicos operados entre Septiembre de 1994 y Febrero de 1997. Se efectuaron registros pre y postoperatorios de las VYI mediante ecografía-Doppler (ED). Su media de edad fúe, de 56,3 años (rango: 38-72 años). Todos los sujetos menos uno eran varones. No hubo casos de trombosis postoperatoria. No se encontraron diferencias significativas entre las medidas ED pre-postoperatorias. En resumen la cirugía cervical oncológica no ganglionar no parece afectar ni la permeabilidad de las VYI, ni las características ED de las mismas (AU)

ABSTRACT

The effect of oncological surgery of the head and neck area without lymph node dissection on the patency and blood flow of the internal jugular veins (IJV) was assessed in a prospective study. Ten IJV of 8 patients who underwent surgery between September 1994 and February 1997 were evaluated. Ultrasound Doppler (UD) of both IJV was performed before and after surgery. Mean age of patients was 56.3 years (range, 38 to 72 years), and all but one were men. There was no case of postoperative thrombosis. No significant differences were found between the preoperative and postoperative measurements. Consequently, oncological surgery of the head and neck area without lymph node dissection did not seem to affect the patency and UD characteristics of the IJV (AU)
