GOLDBLATT was the first to demonstrate that hypertension could be experimentally created by the development of renal ischemia.1 Since that time, various procedures have been undertaken to increase blood flow to the kidney with only limited success.
In 1928, Wearn described a vast sinusoidal plexus lying between the cardiac muscle fibers.2 It remained for Vineberg to clinically capitalize on this anatomical setting by implanting the internal mammary artery into the myocardium.3 He stated that a hematoma did not occur, and that the implanted artery remained patent. This claim was eventually confirmed, in 1962, by Sones and Shirey who used a technique for selective coronary angiography.4
The apparent success of arterial implantation into the myocardium raised the question as to whether the kidney might also have its vascular supply increased by an extrarenal arterial implant. The purpose of this paper is to describe the implantation technique which
