Ultrasound Evaluation of Lower Extremity Arteries After Topical Nitroglycerin Administration

Summary

There have not been any published studies showing the use of topical nitroglycerin on the dilatory effect on the posterior tibial or dorsalis pedis arteries. The objective of this study is to determine the response of the posterior tibial artery and dorsalis pedis artery to topical administration of nitroglycerin. This study may provide further information for the utility of this artery in the treatment of peripheral arterial disease.
