The purpose of this study is to evaluate the effects of respiration, localization of the Doppler sample, and the presence of origin stenosis on the Doppler parameters of coeliac and superior mesenteric arteries in 22 patients undergoing elective abdominal vascular reconstructive surgery under standardized stable anesthesia. Deep inspiration decreased peak systolic and end diastolic velocities of the coeliac artery origin. Proximal to distal Doppler velocities of normal coeliac and superior mesenteric artery origins were comparable. However, in the presence of an origin stenosis, the increase of Doppler velocities at the origin of the coeliac and superior mesenteric arteries is likely to be missed by transabdominal scanning.
本研究的目的是评估在标准化稳定麻醉下接受择期腹部血管重建手术的22例患者中,呼吸、多普勒样本的定位以及起始部狭窄的存在对腹腔干和肠系膜上动脉多普勒参数的影响。深吸气降低了腹腔干起始部的收缩期峰值和舒张末期速度。正常腹腔干和肠系膜上动脉起始部从近端到远端的多普勒速度具有可比性。然而,在存在起始部狭窄的情况下,经腹扫描可能会漏诊腹腔干和肠系膜上动脉起始部多普勒速度的增加。
