Arterial spasm during renal angioplasty.
Spasm of the renal arteries during transluminal angioplasty is a well-documented phenomenon with serious potential sequelae, particularly in young patients with fibromuscular dysplasia. The authors report their experience in 98 cases (105 arteries). Tolazoline, lidocaine, nitrates (or calcium blockers, if available), and heparin should be administered either directly into the renal artery or systemically prior to angioplasty to decrease the incidence and severity of spasm.
