RESUMEN

Es sabido que la presión de pulso es una onda y que tiene velocidades mucho mayores que el flujo san-guíneo. Tales características son inherentes a la transmisión de energía vibratoria y obligan a la resonancia. Este fenómeno ha sido inadecuadamente entendido como el producto de la turbulencia del flujo sanguíneo y sin trascendencia en la patología circu-latoria o aneurismática. La resonancia en el nuevo modelo se propone como generada por la presión de pulso, presentándose sobre segmentos predecibles como lo son las bifurcaciones y aneurismas, generando fuerzas muy intensas de elongación debidas a desacoplamientos vibratorios. Se implantaron 40 aneurismas en la aorta abdominal de ratas Wistar machos mediante técnicas microquirúrgica. Inmediatamente después se realizaron mediciones de la presión de pulso me-diante cronómetro electrónico.
