[The "Preflow technic", a new method of pharmacoradiography of the mesenteric area].
In 16 dog experiments we were able to demonstrate that the conventional selective angiography of the superior mesenteric artery (sma) is performed in a status of underperfusion. By the injection of 50% glucose in a well defined time interval preceding the application of the contrast medium an increase of blood flow can be achieved, which allows the contrast medium to pass through the mesenteric circulation as a bolus. This shows a significantly better opacity of parenchyma and of the venous phase. This technique is easily applicable, carries no side effects on the general circulation and can be recommended for clinical use.
