Hydro- and hemodynamic effects of catheterization of vessels. IV. Catheterization in the dog.
In four dogs the hemodynamic effects of renal artery catheterization has been analysed. Aortic and renal arterial blood pressure and renal blood flow were determined and injection of contrast medium made before during, and after the catheterization maneuver, using catheters with different outer diameters. No effect on the blood pressure or the mean renal blood flow was found until catheters were used with the outer diameter close to the inner diameter of the renal artery.
