摘要

目的:探讨体重指数(BMI)对腹腔动脉(CA)峰值收缩速度(PSV)记录的影响。研究对象与方法:40名男性受试者被纳入前瞻性研究。研究对象根据体重指数分为两组。A组BMI≤25 Kg/m(2), B组BMI >25 Kg/m(2)。两组受试者在仰卧位和禁食4小时时,均采用双工超声记录CA原点直径和PSV。两组人的年龄和性别都是匹配的。采用独立学生t检验检验两组直径与PSV之间是否有统计学意义。结果:A组患者平均年龄(year,±SD)为29.35±1.35,平均BMI (Kg/m(2),±SD)为23.1±1.60。B组平均年龄30±2.1岁,平均BMI为31±5.1。A组CA平均直径(cm,±SD)为0.66±0.076,B组CA平均直径为0.80±0.066。而A组平均PSV (cm/s,±SD)为117±28.1,b组平均PSV(±SD)为102±12.4,独立学生t检验显示两组直径差异有统计学意义(p=0.005), PSV仅达到统计学意义(p=0.049)。结论:BMI较高的受试者由于CA直径较大,可能由于CA起源周围脂肪组织堆积较多,PSV降低。

Subject body mass index affects Doppler waveform in celiac artery by duplex ultrasound.

Objective: The aim of this study is to evaluate the effect of body mass index (BMI) on peak systolic velocity (PSV) recording in the celiac artery (CA).

Subjects & methods: Forty male participants were entered prospectively into the study. The subjects were divided into two groups according to their body mass index. Group A included subjects with BMI ≤25 Kg/m(2) and those in group B with BMI >25 Kg/m(2). The diameter and PSV at the origin of CA of subjects in both groups were recorded while the subject positioned in supine and during expiration phase and fasted for 4 hours using duplex ultrasound. Both groups were matched for age and sex. Independent Student's t-test was used to test if there is any statistical significance between diameter and PSV in both groups.

Results: Group A's, average age (year, ±SD) was 29.35±1.35 and average BMI (Kg/m(2), ±SD) was 23.1±1.60. Group B's, average age was 30±2.1 and their average BMI was 31±5.1. The average diameter (cm, ±SD) of CA in group A was 0.66±0.076 and in group B was 0.80±0.066. However, the average PSV (cm/s, ±SD) was 117±28.1 in group A and 102±12.4 in group B. Independent student t-test showed statistical significance between both groups for the diameter (p=0.005) and just reached statistical significance for PSV (p=0.049).

Conclusion: Subjects with higher BMI showed reduced PSV due to a larger CA diameter and probably due to more fatty tissue accumulation around the CA origin.
