Heparin, compression, and radial artery occlusion: Less is more

Abstract

Key Points Radial artery occlusion is a function of anticoagulation, compression time, compression pressure, and vascular injury from sheath size and puncture attempts. This study showed that increased levels of anticoagulation during transradial cases is associated with a higher incidence of occlusive hemostasis, increasing the risk of radial artery occlusion. Reductions in compression time as made possible by adjunctive hemostatic patches may obviate the need for high doses of heparin.

Effect of Hand Dominance on Radial Artery Spasm and Occlusion: A Prospective Observational Study

“…11 Despite the use of special hydrophilic sheaths and catheters, assisted-tracking techniques and pre-procedural vasodilator and anticoagulant application that reduce complications, RAS is still seen in 10-30% of procedures, RAO occurs in 2-10% of patients after TRA and access-site crossover still varies between 4.6% and 10%. [12][13][14][15] Hand dominance is the most important behavioral asymmetry determined by hemisphere dominance of the brain. 16 It exists in 3 forms as right, left, and mixed.…”
