Breast arterial calcifications are common mammographic findings which are associated with coronary artery disease. The aim of this study was to find the prevalence of breast arterial calcifications in women presenting for mammography in a tertiary care centre.
This descriptive cross-sectional study was performed in the Department of Radiology, in a tertiary care hospital after taking ethical clearance, Reference number 352(6-11)E-2, 077/078, data was collected from Syngovia database from March-June 2021 which included 1614 mammograms. Convenience sampling was done and mammograms evaluated for presence of vascular or non-vascular calcification. Further, vascular calcification was graded. Data was entered in Statistical Package for Social Sciences version 25. Point estimate at 95% Confidence Interval was done, and frequency and proportion were calculated.
The prevalence of breast arterial calcification was 188 (11.6%) at 95% Confidence Interval (10.03-13.2). The mean age of women included in this study was 48.42±9.55 years with the largest number of patients in the age group 40-49 years, 682 (42.3%), and least in the age group 80-89 years, 3 (0.2%). All patients in the age group 80-89 years, 3 (100%) had vascular calcifications followed by 70-79 years group, 22 (57.5%) and none in patients younger than 30 years.
We found an increase in the number and grade of vascular calcifications in breasts with the patient's age. When present breast arterial calcifications must be mentioned in mammogram report. Identification of such calcifications on mammogram should prompt further screening for atherosclerotic disease.
乳腺动脉钙化是常见的乳腺 X 线摄影表现,与冠状动脉疾病相关。本研究旨在探讨三级保健中心行乳腺 X 线摄影的女性中乳腺动脉钙化的发生率。
本研究为描述性横断面研究,在伦理审查通过后于三级保健医院放射科开展,注册号为 352(6-11)E-2、077/078,研究数据来自 2021 年 3 月至 6 月的 Syngovia 数据库,共纳入 1614 例乳腺 X 线摄影检查。采用便利抽样,评估乳腺 X 线摄影中是否存在血管或非血管钙化。进一步对血管钙化进行分级。采用社会科学统计软件包(SPSS)25 版录入数据,计算 95%置信区间的点估计值,以及频率和比例。
1614 例乳腺 X 线摄影中,乳腺动脉钙化的发生率为 188 例(11.6%,95%置信区间:10.03%13.2%)。本研究中女性的平均年龄为 48.42±9.55 岁,年龄最大的组为 4049 岁,682 例(42.3%),年龄最大的组为 8089 岁,3 例(0.2%)。8089 岁年龄组的所有患者(100%)均存在血管钙化,其次是 70~79 岁年龄组,22 例(57.5%),30 岁以下患者中无一例存在血管钙化。
随着患者年龄的增长,乳腺血管钙化的数量和程度逐渐增加。乳腺动脉钙化存在时,必须在乳腺 X 线摄影报告中提及。乳腺 X 线摄影中发现此类钙化时,应提示进一步筛查动脉粥样硬化疾病。
