Complications of transradial catheterization.

Cardiac catheterization via the transradial approach has increased in the United States over the past few years; however, wide-scale adoption still lags in comparison to many international health care systems. Transradial catheterization has a unique set of complications and risks that each operator must appreciate. Radial artery spasm and radial artery occlusion are the most common complications, while bleeding complications such as hematomas and perforations are much less frequent. Each of these issues can be managed successfully with minor changes to one's practice. In this review of the current state of the art, the reader will develop an appreciation for the prevalence of each of the common complications as well as the less common, but potentially highly morbid, events. Throughout this evidence-based review, practical prevention strategies and specific treatment pathways are described for each issue that is covered. Published by Elsevier Inc.
