Color Doppler ultrasonography was used to examine the gallbladder vascular supply in 30 volunteers and in 30 biliary lithotripsy patients pre- and 2 hours posttreatment. A preliminary study of 10 cases of acute cholecystitis was also performed. A cystic artery waveform was obtained in 24 of the volunteers, 18 pre- and postlithotripsy patients, and in 1 of 10 patients with acute cholecystitis. The mean pulsatility indices obtained were 1.04 in the volunteers, 0.98 pre- and 1.02 postlithotripsy (p greater than 0.1). This study shows that the normal gallbladder blood supply can be consistently identified using color Doppler flow imaging and that there is no appreciable difference in the cystic artery pulsatility index following medium-energy shock-wave extracorporeal lithotripsy. Preliminary results in acute cholecystitis suggest that flow is decreased below the sensitivity of the color Doppler imaging system used in this investigation.
采用彩色多普勒超声检查30名志愿者以及30例胆石症患者治疗前及治疗后2小时的胆囊血管供应情况。还对10例急性胆囊炎患者进行了初步研究。在24名志愿者、18例治疗前后的患者以及10例急性胆囊炎患者中的1例获得了胆囊动脉波形。志愿者的平均搏动指数为1.04，治疗前为0.98，治疗后为1.02（p>0.1）。本研究表明，使用彩色多普勒血流成像可始终如一地识别正常胆囊血液供应，且中等能量冲击波体外碎石术后胆囊动脉搏动指数无明显差异。急性胆囊炎的初步结果表明，血流减少至低于本研究中使用的彩色多普勒成像系统的敏感度。
