[A new method for direct measurement of the aortofemoral pressuregradient in connection with translumbar aortography (author's transl)].

A new method to measure simultaneously and directly the aorto-femoral pressure-gradient is described. The study can be performed in connection with translumbar aortography. In addition of being easy to perform the following advantages can be obtained by using this method: 1. Additional angiographic projections are unnecessary. 2. Informations regarding the absolute value of the aortofemoro pressure-gradient at rest and after maximal vasodilatation is obtained.
