The intra-arterial injection of Iskedyl for hyperselective vascular exploration.

The development of spasm with the introduction of catheters into very small calibered arteries has tended to interfere with routine superselective catheterization. To overcome this problem the vasodilating drug Iskedyl, which containes raubasine 6.25 mg and dihydroergosistine 0.3125 mg in an ampule of 2.5 ml, has been injected into the artery being manipulated. The study was conducted on 112 patients undergoing hyperselective explorations of intracranial, thoracic, abdominal and peripheral arteries of small caliber and the results have been most gratifying and encouraging.
