肠系膜上动脉方位与胡桃夹现象的体位关系

Relationship between the position of superior mesenteric artery and the posture of the nut cracker phenomenon

目的分析胡桃夹现象(NCP)患者肠系膜上动脉(SMA)方位与体位的关系,探讨体位疗法对NCP的治疗作用。方法46例NCP患者,根据SMA的不同方位分为正前位、左前位、右前位3组,并对各组病例进行平卧位、左侧卧位、右侧卧位,前倾位和直立位的左肾静脉超声检查,对每组各种体位超声测值进行比较。结果各组患者直立位NCP均加重,前倾位均减轻。左前位组左侧卧位减轻,右前位组右侧卧位减轻。结论SMA方位与不同体位NCP缓解有关。多体位超声检查对制定个体化的体位治疗方案具有重要意义。

Objective To analyze the relationship between the superior mesenteric artery（SMA） in different positions and nut cracker phenomenon（NCP） in different postures,and to explore the effect of postural therapy on the NCP.Methods Based on the different positions of SMA,46 NCP patients were divided into 3 groups：front,left,and right anterior.The left renal vein in all cases were examined with ultrasonography at the supine position,the left decubitus position,the right decubitus position,anteversion position and erect position,then the values of different positions in each group were compared.Results NCP appeared aggravated at the erect position of each group,and was relieved at the anteversion position,the left decubitus position of the left anterior group,and the right decubitus position of the right anterior group.Conclusion The position of SMA is related to the relief of NCP in different postures.Ultrasonography at different postures is of great significance to design the individual postural therapy for patients with NCP.
