Mother-in-Child Assisted Tracking (MiCAT): A Mechanical Technique to Overcome Severe Radial Artery Spasm.

The Journal of invasive cardiology, 2022
BACKGROUND Severe radial artery spasm (RAS) and tortuosity may hinder guide catheter advancement and manipulation, requiring the arterial access site to be changed.

Radial Long Sheath Angioplasty for Proximal Severe Flow Limiting Radial Artery Spasm Utilizing the Dotter Technique.

World Neurosurgery, 2022
BACKGROUND Although studies continue to demonstrate the advantages of transradial access (TRA) for neurointerventions, radial artery spasm (RAS) remains a frequent cause of TRA failure. Dotter initially described a technique to dilate areas of peripheral

A randomized trial of flow-mediated dilation to prevent radial artery spasm during transradial approach.

Minerva Cardioangiologica : a Journal on Cardiovascular Pathophysiology, Clinical Medicine and Therapy, 2021
BACKGROUND Although transradial approach has been increasingly preferred for percutaneous coronary interventions, radial artery spasm (RAS) is still one of the major disadvantage.

Measurement of radial artery spasm using an automatic pullback device

Catheterization and Cardiovascular Interventions, 2001
AbstractCurrent evaluation of radial artery spasm (RAS), a frequent finding during the transradial approach for coronary angiography and angioplasty (TRA), is subjective. A quantitative measure of RAS will help in evaluation and comparison of management strategies.

Pretreatment with α-adrenergic blockers for prevention of radial artery spasm

The Annals of Thoracic Surgery, 2002
Radial artery (RA) conduits are prone to early vasospasm. Current intraoperative treatment with papaverine fails to inhibit postoperative RA constriction. Pretreatment with topical a-antagonist solutions can inhibit RA vasoconstriction and cause dilatation for a longer period than achieved with papaverine.In 10 patients undergoing myocardial ...

Transdermal Nitroglycerin Patch as a Potential Pretreatment to Prevent Radial Artery Spasm During Transradial Cardiac Catheterization.

The Journal of invasive cardiology, 2021
A recent guideline has recommended the radial artery as the access site for coronary catheterization due to lower risk of bleeding and vascular complications.

Abstract 4371559: Intra-Arterial Vasodilators for Radial Artery Spasm and Occlusion Prevention in Trans-radial Coronary Procedures: A Network Meta-Analysis of Randomized Control Trials

Circulation
Background: Radial artery access is the preferred approach for coronary procedures, however, radial artery spasm (RAS) and radial artery occlusion (RAO) remain frequent complications, and no standardized prevention strategy has been universally ...

Differential Predictors of Severe Versus Milder Radial Artery Spasm: Insights From a Large Contemporary Distal Radial Access Cohort

Catheterization and cardiovascular interventions
Radial artery spasm remains a frequent procedural challenge in transradial intervention; however, its predictors may differ for severe and milder forms of spasm. This distinction is poorly characterized, particularly in contemporary distal radial access (

Implementation of a radial long sheath protocol for radial artery spasm reduces access site conversions in neurointerventions

Journal of NeuroInterventional Surgery, 2020
Background Many neurointerventionalists have transitioned to transradial access (TRA) as the preferred approach for neurointerventions as studies continue to demonstrate fewer access site complications than transfemoral access.
