【摘要】：目的:采用256层螺旋计算机断层摄影术(MSCT)对右心耳及其毗邻的形态结构进行定量研究,为右心耳临床介入和外科治疗提供影像学依据。方法:回顾性分析我院行计算机断层摄影术血管造影(CTA)检查结果阴性者200例,男96例,女104例,40岁者29例,40~60岁者114例,60岁者57例。将原始扫描数据进行右心耳重建,对右心耳容积及径线等参数进行测量,并从性别和年龄方面进行比较,提出右心耳各参数95%正常参考值范围。结果:(1)右心耳容积、高度、基底部长径、基底部周长、正位展距男性均大于女性,差异均有统计学意义(P均0.05)。经体表面积标化后,右心耳基底部长短径、面积及周长女性均大于男性,差异均有统计学意义(P均0.05)。(2)40岁者右心耳正位展角及正位展距较40~60岁及60岁者大(P0.05),40~60岁者与60岁者间差异无统计学意义(P0.05)。(3)提出右心耳各参数95%正常参考值范围:容积4.83~19.97 ml、高度21.46~41.80 mm、基底部长径25.89~41.65 mm、基底部短径19.34~36.24 mm、基底部面积459.30~1 093.28 mm~2、基底部周长86.16~147.04 mm、正位展角1.67°~31.23°、正位展距8.07~34.37 mm。结论:256层MSCT可以对右心耳解剖结构相关参数进行定量研究,并初步建立右心耳各参数95%正常参考值范围,为临床治疗右心耳相关疾病提供影像学参考。
[Abstract]:Objective: to quantitatively study the morphologic structure of the right atrial appendage and its adjacent by 256-slice spiral computed tomography (MSCT), and to provide the imaging basis for the clinical intervention and surgical treatment of the right atrial appendage. Methods: a retrospective analysis was made on 200 cases with negative (CTA) results of computed tomography angiography in our hospital, including 96 males, 104 females, 29 40 years old, 114 40 years old and 57 60 years old. The original scanning data were reconstructed and the parameters such as volume and diameter of the right atrial appendage were measured and compared from gender and age. The range of 95% normal reference values of each parameter of the right atrial appendage was put forward. Results: (1) the volume and height of the right atrial appendage, the length of the base, the circumference of the base and the distance between the male and the female were significantly higher than those in the female (all P 0.05). After the surface area was standardized, the length, area and circumference of the base of the right atrial appendage were larger in the female than in the male. There was significant difference between the two groups (P < 0. 05). (2). The angle and distance of right atrial appendage in 40 years old were larger than those in 40 and 60 years old (P0.05). There was no significant difference between 4060 years old and 60 years old (P0.05). (3). The range of 95% normal reference value of each parameter of right atrial appendage was put forward: volume 4.83 ~ 19.97 ml, height 21.46 ~ 41.80 mm, base length and diameter 25.89 ~ 41.65 mm,. Base bottom short diameter 19.34 ~ 36.24 mm, base bottom area 459.30 ~ 1 093.28 mm~2, base bottom circumference 86.16 mm, 147.04 mm, forward angle 1.67 掳~ 31.23 掳, orthostatic spread distance 8.07 ~ 34.37 mm. Conclusion: 256-layer MSCT can be used to quantitatively study the anatomical structure parameters of right atrial appendage, and to establish 95% normal reference range of right atrial appendage parameters, which can provide imaging reference for clinical treatment of right atrial appendage related diseases.
