Correlations between age, body size, sex, and conformation and ultrasound-measured femoral vessel diameter in the dog, with implications for transvascular procedural planning.

Transvascular interventional radiology procedures have advanced in veterinary medicine, but basic knowledge about expected vascular size and vascular imaging requires further exploration. A prospective analytical study of 230 client-owned dogs was carried out to investigate correlations between ultrasound-measured femoral artery (FA) and femoral vein (FV) diameter and various morphometric and demographic dog variables, compare ultrasound-measured femoral vessel diameter to diameter predicted by body weight, compare right- and left-sided femoral vessel diameter, and assess measurement repeatability. Internal diameter of the FA and FV was measured with ultrasound bilaterally.
