Radial Artery Access, Hemostasis, and Radial Artery Occlusion
Interventional Cardiology Clinics, 2015Radial artery access is usually achieved using a micropuncture system. Hydrophilic introducers are used to improve comfort, probably by reducing spasm. A vasodilator cocktail should be administered to prevent severe spasm and anticoagulation; usually, unfractionated heparin is administered to prevent subsequent radial artery occlusion (RAO). Hemostasis

Ulnar artery catheterization with occlusion of corresponding radial artery
Catheterization and Cardiovascular Interventions, 2004AbstractThe transradial approach to coronary angiography has become a popular technique. Because of potential advantages, the transulnar approach has also recently been described. We report a successful case of transulnar catheterization with documented occlusion of the radial artery and normal inverse Allen test in a patient with limited vascular ...

Novel oral anticoagulants in the treatment of radial artery occlusion
Catheterization and Cardiovascular Interventions, 2021AbstractTransradial access of the vascular system for coronary angiography and percutaneous coronary intervention has become the primary approach in several cardiac catheterization laboratories across the world. The paradigm shift from transfemoral access has been driven by improved outcomes in patients undergoing these cardiac procedures by ...

Heparin, compression, and radial artery occlusion: Less is more
Catheterization and Cardiovascular Interventions, 2021Key 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 ...

Transulnar recanalization of a chronic radial artery occlusion
Cardiovascular Revascularization Medicine, 2017Trans-ulnar access is a viable alternative approach by experienced operators when the radial and femoral arteries cannot be accessed or used to preserve the contralateral radial artery as possible vascular graft for coronary bypass surgery, hemodynamic monitoring, or shunt creation for hemodialysis.

Radial artery occlusion: Preventing Insult to Injury
Catheterization and Cardiovascular Interventions, 2015Key Points Intra‐arterial nitroglycerin prior to transradial sheath removal may reduce the incidence of radial artery occlusion (RAO). Operators must observe careful attention to all aspects of transradial catheterization, particularly patent hemostasis; as well as independently monitor the institutional incidence of RAO to prompt improvements in ...

Interosseous artery as an access artery in case of late radial artery occlusion
Catheterization and Cardiovascular Interventions, 2017We report a new technique of arterial access through the ipsilateral interosseous artery in a case of late radial artery occlusion (RAO). RAO, although not frequent, is a limiting iatrogenic complication after transradial intervention (TRI) and precludes repeat use of the same radial artery for future procedures. Our technique involves obtaining access

Transulnar catheterization in patients with ipsilateral radial artery occlusion
Catheterization and Cardiovascular Interventions, 2013BackgroundThe transradial approach to percutaneous coronary intervention (PCI) has recently gained popularity among interventionalists. However, radial artery occlusion (RAO) limits the ability for repeat catheterization. In current practice, transulnar catheterization is thought to be a contraindication in patients with ipsilateral RAO ...

Radial artery occlusion by a paradoxical embolism: A case report
The Journal of Hand Surgery, 1995Paradoxical embolism was first described by Cohnheim in 1877. It is defined as a systemic arterial embolization caused by the passage of a venous thrombus through a right-to-left circulatory shunt. This shunt can be due to an intracardiac defect, or an arteriovenous communication.
