Prevalence of Distal Radial Artery Occlusion in Cardiovascular Catheterization Via Distal Radial Access

Prevalence of Distal Radial Artery Occlusion (DRAO) in Patients Undergoing Cardiovascular Catheterization Via Distal Radial Access (DRA)

Explore the prevalence of distal radial artery occlusion after cardiac catheterization via distal radial artery and the risk factors

Cardiac catheterization via distal radial artery is prevalent worldwide, which can reduce the prevalence of radial artery occlusion. However, the distal radial artery occlusion has not been detected. This study is designed to explore the prevalence of distal radial artery occlusion in patients undergoing cardiac catheterization via distal radial access at 1 day and 3 months after the procedure, which is explored by ultrasound. In addition, the risk factors of distal radial artery occlusion are also analyzed.

Inclusion Criteria:

• Age ≥ 18 years;
• Palpable distal radial artery

Exclusion Criteria:

• Age ≥ 90years;
• Height≥ 185cm;
• Cardiogenic shock;
• Refuse to sign the written informed consent.
