超声评估椎动脉起始段纡曲

Ultrasonic evaluation on tortuosity of vertebral artery ostium

目的观察超声评估椎动脉起始段(VAO)纡曲的价值。方法纳入37例于颈内静脉置管前接受颈部血管超声检查的结直肠肿瘤患者,并根据VAO纡曲角度将其分为≤90°组(n=10)及>90°组(n=27)。比较2组患者一般资料,包括性别、年龄及体质量指数(BMI),以及超声特征,包括VAO纡曲角度及活动度等;分析超声评估VAO纡曲的价值。结果≤90°组与>90°组患者性别、BMI及右侧VAO活动度差异均无统计学意义(P均>0.05),而≤90°组患者年龄及左侧VAO活动度均大于>90°组(P均<0.05)。平静呼吸及深吸气末时,2组患者左侧VAO纡曲角度均小于右侧(P均<0.05);且平静呼吸状态时,左侧VAO纡曲角度小于深吸气末(P<0.05)。结论超声对评估VAO纡曲角度及其在呼吸运动下的变化具有一定价值。

Objective To observe the value of ultrasound for evaluation on the tortuosity of vertebral artery ostium(VAO).Methods Totally 37 patients with colorectal tumors who underwent cervical vascular ultrasound before internal jugular vein catheterization were enrolled.The patients were then divided into≤90°group(n=10)and>90°group(n=27)according to the tortuosity angle of VAO.The general data,including gender,age and body mass index(BMI),as well as ultrasonic indexes,including tortuosity angle and activity of VAO were compared between 2 groups.The value of ultrasound for evaluating tortuosity of VAO was analyzed.Results There was no significant difference of patients'gender,BMI nor activity of right VAO between≤90°group and>90°group(all P>0.05),but the patients'age and activity of left VAO in≤90°group were greater than those in>90°group(both P<0.05).The tortuosity angle of left VAO was smaller than that of the right under calm breathing and at the end of deep inhalation(both P<0.05),and the tortuosity angle of left VAO under calm breathing was smaller than that at the end of deep inhalation(P<0.05).Conclusion Ultrasound had certain value for evaluating tortuosity angle of VAO and its changes under respiratory motion.
