[Investigation by borrowing-lending-phenomenon under conditions of intraarterial induced vasodilatation (author's transl)].

In fourty patients with peripheric atherosclerosis obliterans blood flow was measured by means of venous occlusion plethysmography during an intraarterial and an intravenous infusion of ATP. The intraarterial application showed a significantly higher increase of blood flow than the intravenous in the sick extremities. The "borrowing-lending-phenomenon" happened more seldom than after an intravenous load. This withdrawal of blood occurred most frequently in patients with proximal occlusions, when the infusion reached casually the arteria femoralis profunda only. The "borrowing-lending-phenomenon" can be measured by the poststenotic pressure and by the volume of blood flow in time. Then the patients complain about a begining or an increasing of an ischemic pain at rest.
