Abstract
Este estudio se llevó a cabo para caracterizar el flujo sanguíneo normal del testículo canino y medir la velocidad sistólica máxima (PSV), la velocidad telediastólica (EDV), el índice de resistencia (RI) y el índice de pulsatilidad (PI) de las arterias testiculares semanalmente durante un período de 6 meses en cinco perros Beagle sanos, así como para evaluar si se producían cambios a lo largo de este tiempo.
Los exámenes ecográficos se realizaron con un transductor lineal de 11 MHz. Los vasos testiculares se subdividieron en tres categorías: arterias supratesticulares, arteria marginal y vasos intratesticulares. En las arterias supratesticulares se registraron dos mediciones, en la porción craneal y en la porción en asa (looping).
No se observaron diferencias significativas en ninguno de los parámetros estudiados durante los 6 meses que duró el estudio. La porción craneal de la arteria supratesticular mostró un patrón de flujo característico de vaso de alta resistencia, mientras que en la porción en asa de la arteria supratesticular, así como en las arterias marginales e intratesticulares, el flujo presentó un patrón de baja resistencia.
Los valores de PSV, RI y PI fueron más elevados en la porción craneal de la arteria supratesticular, seguidos por la porción en asa de la arteria supratesticular, la arteria marginal y los vasos intratesticulares. Las mediciones de EDV fueron mayores en la porción en asa de la arteria supratesticular.
This study was performed to characterize the normal blood flow of the canine testis and to measure the peak systolic velocity (PSV), end-diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI) of testicular arteries weekly during a period of 6 months in five healthy Beagle dogs and to evaluate whether there were any change along this time. The ultrasonographic exams were made with an 11 MHz linear transducer. The vessels of the testes were subdivided into three categories: supratesticular arteries, marginal artery and intratesticular vessels. At the supratesticular arteries, two measurements were recorded at the cranial and the looping parts. No significant differences in any of the parameters studied were observed for the 6 months that the study was performed. The cranial part of the supratesticular artery showed a flow pattern of high-resistive vessel, whereas in the looping part of the supratesticular artery, marginal and intratesticular arteries, the flow showed a low-resistance pattern. PSV, RI and PI values were higher at the cranial part of the supratesticular artery, followed by the looping part of the supratesticular artery, marginal and intratesticular vessels. EDV measurements were higher in the looping part of the supratesticular artery.
