Randomized Controlled TrialEffects of subcutaneously infiltrated nitroglycerin on diameter, palpability, ease-of-puncture and pre-cannulation spasm of radial artery during transradial coronary angiography.
The success of transradial catheterization depends on meticulous access of radial artery which in turn depends on palpating a good radial pulse. ⋯ Subcutaneously infiltrated nitroglycerin leads to significant vasodilation of radial artery. This avoids pre-cannulation spasm of radial artery, enhances palpability of the radial pulse and thus makes the puncture of radial artery easier.

Cardiovascular manifestations of tertiary syphilis include aortitis, aortic root dilation, aneurysm formation, aortic regurgitation, and coronary ostial stenosis. Coronary ostial lesions have been detected in as many as 26% of patients with syphilitic aortitis. However nonostial coronary stenosis and coronary aneurysms in same patient is rarely described in cardiovascular syphilis.
