Complications of radial catheterization
Optical coherence tomography (OCT) has been used by Yonetsu et al to define the damage to the radial artery in 73 arteries of 69 patients [1]. 32% of patients developed intimal tears and 16% of patients developed medial dissections. Repeat catheterization was associated with increased fibro-intimal hyperplasia. Cardiac catheterization via the radial approach may render the radial artery unsuitable for coronary artery bypass grafting. There can be a loss of pulse in about 4% of cases. Use of smaller guide catheters and sheathless guides may potentially reduce the risk of these complications.
