Transradial catheterization is usually performed via 5\u2010Fr or 6\u2010Fr catheters; 7\u2010Fr sheath insertion enables complex coronary interventions but may increase the RAO risk.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We prospectively enrolled 130 consecutive patients undergoing complex TRI using 7\u2010Fr sheaths. Radial artery ultrasound assessment was performed before and after TRI. Early RAO was defined as the absence of flow on ultrasound within 6\u201324\u2009hr after TRI. Multivariate logistic regression was used to determine the factors related to early RAO after TRI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>7\u2010Fr sheaths were mainly used for chronic total occlusion (44.6%), bifurcation (30.0%), and tortuous calcification (25.4%) lesions. All patients were successfully sheathed. Percutaneous coronary intervention (PCI) procedural success was 96.2%; 119 patients (91.5%) had preserved radial artery patency after TRI. All 11 RAO cases (8.5%) were asymptomatic. The radial artery diameter was significantly larger postoperatively (3.1\u2009\u00b1\u20090.4\u2009mm) than preoperatively (2.6\u2009\u00b1\u20090.5\u2009mm) (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). No parameters significantly differed between patients with and without RAO. TRI history was the only independent risk factor of early RAO (odds ratio: 6.047, 95% confidence interval: 1.100\u201333.253,<jats:italic>p<\/jats:italic>= .039).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>7\u2010Fr sheath use after transradial access for complex PCI is feasible and safe.
