[Significance of the use of glycerol trinitrate in functional angiologic diagnosis].

On 95 patients functional rheographic investigations and pressure measurements of the arteries of the big toes were carried out before and after the administration of glycerol trinitrate. Using the nitrate-induced decrease of the tone of the vessels persons with healthy vessels could more certainly be differed from patients with organic arterial occlusive disease of the lower extremities stage I and IIa. Despite the administration of glycerol trinitrate the rheography, however, does not reach the extraordinarily high reliability of the ultrasound-Doppler-pressure measurement in the early diagnosis of the arterial occlusive disease.
