[Angiographic and clinical evaluation of the topical administration of nitrate derivatives in distal obstructive arteriopathies of the legs. Initial experiences].
The vasodilator effect obtained by the topic use of a nitroglycerin compound (TNG) has been angiographically tested on 11 patients affected by distal arteriopathy of the legs. All patients presented arteriosclerotic vascular lesions; two of them also suffered from diabetic angiopathy. Arteriography of the legs has proved to be a very important tool in the evaluation of the patients' response to the administration of the drug. An hour after 80 mg of TNG had been applied to the skin of the examined leg, arteriography showed a marked dilation, especially of the muscular arteries and the undamaged tracts of the arteries of the legs. Angiographic evaluation of the functional blood supply thus obtained provides prognostic information and helps in the choice of the subsequent therapy. Furthermore, the clinical efficacy of prolonged treatment with this drug has been tested in 10 out of the 11 patients. They all responded with an immediate and persistent hemodynamic improvement, evaluated according to Fontaine's classification.
