A patient with conditions such as Acute Left Ventricular Failure when standing erect, the lower lobe veins contain more blood, and the upper lobe veins remain relatively small. In acute LVF, there is such a back-pressure that the upper lobe veins also fill with blood and become engorged. This is referred to as upper lobe diversion.
