Objective: imaging analysis and its influencing factors of vascular tortuosity of the radial artery path, variation multiple correlation regression analysis, to explore transradial coronary intervention in the diagnosis and treatment of patients, vascular tortuosity of the radial artery path, mutation incidence and its associated effects factor. Method: chronologically consecutive Guangxi Medical University Affiliated Hospital interventional transradial line of coronary heart disease for the first time were 1400 cases from July 2007 to September 2010. Inclusion criteria: (1) Allen test was positive; (2) The right upper limb deformities, no active infection focus puncture site; (3) for the first time, CAG or PCI via the radial artery, and complete the radial artery paths vascular angiography (RAG). Exclusion criteria include: (1) Allen test was negative; ⑵ weak pulse or pulseless radial artery; (3) the failure of the radial artery puncture and the need to replace the artery approach to complete contrast; (4) previous transradial line CAG or by PCI; (5) patients with peripheral vascular disease; ⑹ the forearm arterial trauma history; ⑺ severe renal insufficiency the; ⑻ hemodialysis history. The records of all patients with a history of information underwent radial the artery path artery angiography, record the radial artery Path vascular tortuosity, variations in again next coronary angiography (CAG) or coronary intervention the therapeutic (PCI). Classic computer quantitative coronary angiography (QCA) measurements of the radial artery, brachial artery, subclavian artery, brachiocephalic trunk artery tortuosity and variability contrast imaging analysis, and the patient's ethnicity, gender, age, height, weight, body mass index, blood pressure, blood sugar, blood lipids and smoking and other factors, multivariate logistic regression analysis to explore the interventional transradial line coronary heart disease patients, radial artery, brachial artery, subclavian artery, brachiocephalic trunk artery tortuosity and variability incidence and related factors, evaluate the application of the Transradial coronary heart disease interventional techniques in Guangxi crowd coronary heart disease treatment in the feasibility and safety. Results: arteriography found 170 (12.1%) patients with vascular tortuosity of the path of the radial artery, and variation in 57 (4.1%) patients. The blood vessel tortuosity occurred as follows: the radial artery tortuosity was 3.6% (51/1400), about 0.4% of the brachial artery tortuosity (5/1400), subclavian artery tortuosity of about 5.4% (75/1400), brachiocephalic trunk artery tortuosity of about 2.8% (39/1400); occurrence of the abnormal blood vessels are as follows: 1.7% (24/1400) of high radial artery, radial artery rings 0.6% (8/1400), the double radial artery and 0.1% (2/1400), double brachial artery and 0.1% (2/1400) 0.4% (6/1400), small subclavian artery, esophagus after the origin of the right subclavian artery 0.6% 0.1% (8/1400), the small arteries of the brachiocephalic trunk (2/1400) , brachiocephalic trunk artery malformations 0.4% (5/1400). The Guangxi crowd radial artery path vascular tortuosity subclavian artery and radial artery tortuosity most common. Transradial intervention the clinic overall success rate of 96.1% (1346/1400). Radial the arterial paths vascular tortuosity and variability in patients, interventional transradial failure rate were 11.8% and 22.8%, respectively, in patients with normal radial artery path failure rate was 1.8% (21/1173). Multivariate logistic regression analysis showed that age (OR = 2.695, 95% CI 2.232 - 3.253; P = 0.000), female (OR = 5.127, 95% CI 3.000 - 8.762; P = 0.000), height (OR = 0.612, 95% CI 0.465 - 0.807; P = 0.000), body mass index (OR = 2.377, 95% CI 1.834 - 3.082; P = 0.000), hypertension (OR = 1.668, 95% CI 1.132-2.458; P = 0.010), hyperlipidemia disease (OR = 1.273, 95% CI 1.425-2.049; P = 0.034) and smoking (OR = 5.750,95% CI 3.636-9.093; P = 0.000), are the main factors affecting vascular tortuosity of the radial artery path. Factors independently associated with vessel variation of the radial artery path for women (OR = 3.613, 95% CI 3.208 - 7.826; P = 0.000). Conclusion: Guangxi crowd radial artery path vascular tortuosity and variations are not uncommon, and clinics failed one of the main reasons for transradial coronary intervention. Elderly, female, short stature, high body mass index, hypertension, hyperlipidemia, and smoking are the main factors affecting vascular tortuosity radial artery path. While women are main factors is the radial artery paths vascular variation.
