To evaluate the influence of the technical problems experienced when scanning transabdominally, a comparison was made between transabdominal and intra-abdominal Doppler parameters of the aorta and the splanchnic arteries. Peroperative color duplex sonography of the abdominal aorta and the splanchnic arteries was performed on 25 patients who were undergoing abdominal vascular reconstructive surgery under stabilized standardised anaesthesia. Doppler samples and diameter measurements were taken of the aorta, celiac, common hepatic, splenic, superior and inferior mesenteric arteries, both trans- and intra-abdominally. Significantly higher velocities were recorded in the celiac artery during intra-abdominal examinations. There was a trend toward higher recorded velocities in the other vessels. There was also a significant difference in the diameter measurements of most of the vessels. The trans- and intra-abdominal results were not always equivalent. The differences were not due to technical aspects. Transabdominal duplex sonography is difficult and may not be completely accurate in detecting quantitative flow parameters in the splanchnic arteries.
为评估经腹扫描时遇到的技术问题的影响，对腹主动脉和内脏动脉的经腹与腹内多普勒参数进行了比较。对25例在稳定的标准化麻醉下接受腹部血管重建手术的患者进行了腹主动脉和内脏动脉的术中彩色双功超声检查。经腹和腹内均对主动脉、腹腔干、肝总动脉、脾动脉、肠系膜上动脉和肠系膜下动脉进行了多普勒取样和直径测量。腹内检查时腹腔干的记录速度明显更高。其他血管的记录速度有升高趋势。大多数血管的直径测量也存在显著差异。经腹和腹内结果并不总是等效的。差异并非由于技术方面。经腹双功超声检查在检测内脏动脉的定量血流参数方面存在困难且可能不完全准确。
