Papaverine use for radial artery sheath entrapment

Özet

Transradial approach currently represents the preferred arterial access approach for percutaneous coronary procedures primarily due to the reduced access-site complications comparedwith femoral access (1). However, because of its thinner caliberand higher sensitivity to mechanical and humoral stresses thanother somatic vessels, radial artery is prone to spasm (2). In general, spasm is a benign complication that can be resolved with nitrates or Ca 2+-channel blockers, but in some rare cases, the spasmis so severe and prolonged that it may lead to radial sheath entrapment, with documented rare cases of radial avulsion (3).
