[Distal hemoperfusion during coronary angioplasty with prolonged balloon inflation].

We present the results of 6 coronary angioplasties associated with coronary distal hemoperfusion by an injection pump. The inflation mean time was 5 min 10 sec and the quantity of perfused blood was 43 +/- 14 ml. The procedure was successful in all cases. No biochemical alterations were detected in the perfused blood. A significant clinical and electrocardiographic improvement was observed in all but 2 cases. The cause was the occlusion of a collateral branch and a high flow pattern, respectively. Technical aspects and usefulness of this and other perfusion systems are analysed.
