Abstract: Objective To explore the incidence and associated factors of aortic artery calcification (AAC) by lateral lumbar X-ray score in maintenance hemodialysis (MHD) patients.Mehtods A total of 155 MHD patients with complete clinical data in our hospital were enrolled in the study.Lateral lumbar X-ray score of the abdominal aorta was used to determine AAC in MHD patients.Results Aortic calcification was most severe in front of the fourth lumbar segment and ameliorated in higher lumbar levels.63.63％ of MHD patients presented visible calcification in the abdominal aorta,and 28.39％ had severe calcification with more than three segments.Age (OR=1.094,P＜0.01),dialysis vintage (OR=1.013,P=0.022),triglyceride (OR=1.261,P=0.030) and phosphate level (OR=1.324,P=0.023) were risk factors of abdominal aorta calcification,however serum albumin level (OR =0.239,P=0.013) was protect factor of aortic calcification.Conclusions Incidence of AAC is quite high in MHD patients and associated with increasing of age,duration of hemodialysis,serum triglyceride,phosphate level and plasma albumin.The semi-quantitative X-ray method of determining vascular calcification is less expensive and may be widely available clinically.
