Transradial access for peripheral and cerebrovascular interventions.

OBJECTIVES: In the present review, we report indications, equipment, techniques, results, and complications of transradial access (TRA) in peripheral as well as in cerebrovascular interventions.
BACKGROUND: Percutaneous peripheral and cerebrovascular interventions are usually performed using transfemoral access; however, the risk of vascular complications with this approach is not negligible. Moreover, femoral access may be precluded by advanced vascular disease, and brachial access has been traditionally used as an alternative approach despite the risk of local complications. While TRA has gained wide acceptance for coronary procedures, little is known about its use for peripheral and cerebrovascular interventions. Thanks to dedicated equipment, most vascular territories may now also be treated by TRA.
CONCLUSIONS: TRA may become the alternative access of choice for peripheral and cerebrovascular interventions when femoral access is precluded. In addition, TRA may become the preferred access for the treatment of selected peripheral lesions.
