Radial artery access for peripheral endovascular procedures.

Objective: The radial artery is often used for coronary angiography, with a demonstrated decrease in local complications and an increase in postoperative mobility of the patient. Data on radial artery access for peripheral endovascular procedures, however, are limited. We describe our experience with radial artery access for diagnostic and endovascular interventions.

Methods: Between February 2012 and March 2015, there were 95 endovascular procedures performed using radial artery access in 80 unique patients. Demographic and clinical data were recorded. Perioperative, postoperative, and 30-day follow-up data were evaluated retrospectively for major and minor complications. Major adverse events included any immediate hospitalization admission, stroke, hand amputation, bleeding requiring transfusion, hematoma requiring surgery, and death. Minor complications included superficial bleeding and hematoma.

Results: The patients (52.6% male, 47.4% female) had a mean age of 72.1 ± 9.4 years. Radial artery access was used for diagnostic purposes in 15.8% of all procedures and for therapeutic intervention, including angioplasty and stenting, in 84.2%. The radial artery was the only access point in 80% of patients and was accessed in conjunction with other sites in 20%. Percutaneous access was achieved in 100% of patients with a 100% technical success rate. Hemostasis after catheterization was achieved by manual compression (22.1%) and TR band (Terumo Medical, Tokyo, Japan; 77.9%). Major adverse events occurred in three cases (3.2%) and were unrelated to radial artery access. Radial artery access site-related complications occurred in three cases (3.2%), all of which were minor hematomas that required no treatment. The risk of radial artery complication was not associated with procedure type, vessels treated, or use of heparin. The incidence of stroke, hand ischemia, and upper extremity limb or finger loss was 0%.

Conclusions: Radial artery access for peripheral endovascular procedures appears to be safe and effective and should be considered more often. Complication rates are lower than those reported for femoral artery access.
