Radial artery occlusion (RAO)
ОглавлениеRAO is the most common post‐procedural complication of transradial access. Patients are often asymptomatic and hand function is unaffected (irrespective of Allen’s or Barbeau test) due to collateral perfusion. However, RAO precludes future radial artery procedures including repeat cardiac catheterization, arterial graft harvesting for coronary artery bypass grafts, and arteriovenous fistula formation in end stage renal failure patients [46]. Therefore, multiple strategies are available to minimize RAO including avoidance of repeat arterial puncture, a low sheath to artery size ratio, administration of intraprocedural heparin, and maintenance of radial artery patency during hemostasis after transradial access. More recently, there has been evidence suggesting that ipsilateral ulnar artery compression post‐procedure facilitates radial artery recanalization and reduces RAO (from 3.0% to 0.9% in a single center study) [47]. Most occlusions will recanalize after one month [48].
