Transient and Regional Ischemia Related to Continuous Saline Solution Infusion during Radial Artery Access

This case series illustrates a radial access complication seen in 7 of 9 consecutive patients (age range, 44-53 y) undergoing uterine artery embolization in May and June 2017. Demonstrative images and videos identify a transient and clinically consequential skin ischemia caused by intraprocedural saline solution infusion through the occlusive radial artery sheath. All complications documented were classified as mild adverse events (class A) according to Society of Interventional Radiology criteria. Complication severity ranged from transient blanching to ischemic necrosis of the skin. Operator cognizance of this phenomenon with appropriate adjustment of saline solution infusion rates will prevent tissue ischemia and necrosis in radial access cases.
