目的
回顾性评估64排CT对Calot三角及其周围胆囊管和胆囊动脉的术前显示。
材料和方法
获得机构审查委员会批准，放弃知情同意。共有245名连续患者（133名男性，112名女性），包括48名随后接受胆囊切除术的患者，进行了检查。两名独立的观察员评价了CT数据集的基础上，轴向截面，冠状面和矢状面多平面重建，和三维容积渲染。胆囊动脉和Calot三角之间的关系也进行了评估，Calot三角由肝脏的下表面，肝总管和胆囊管界定，每个病人都根据胆囊动脉的起源和Calot三角的路线进行了分类。进行统计分析，并计算百分比和置信区间。
结果
245例中234例显示胆囊动脉。223例同时显示胆囊三角和胆囊动脉。173例患者在Calot三角中可见一条胆囊动脉，12例患者在Calot三角中可见两条胆囊动脉。18例患者在Calot三角中发现一条动脉，其副动脉来自Calot三角外的不同来源，20例患者未发现胆囊动脉。在随后接受胆囊切除术的48例患者中，42例（92%; 95%置信区间：87%，98%）观察到囊性动脉。胆囊动脉与Calot三角的关系与所有患者的手术记录一致。
结论
胆囊管和胆囊动脉的结构可以在术前用64排CT显示。
PURPOSE
To retrospectively assess 64-detector row computed tomography (CT) in the preoperative depiction of the cystic duct and cystic arteries in and around the Calot triangle.
MATERIALS AND METHODS
Institutional review board approval was obtained, with waiver of informed consent. A total of 245 consecutive patients (133 men, 112 women), including 48 patients who subsequently underwent cholecystectomy, were examined. Two independent observers evaluated the CT data set on the basis of axial sections, coronal and sagittal multiplanar reformations, and three-dimensional volume rendering. The relationship between the cystic arteries and the Calot triangle--which is bordered by the undersurface of the liver, common hepatic duct, and cystic duct--was also evaluated, and each patient was classified on the basis of the origin of the cystic arteries and the course to the Calot triangle. Statistical analysis was performed, and percentages and confidence intervals were calculated.
RESULTS
The cystic arteries were delineated in 234 of the 245 patients. Both the Calot triangle and the cystic arteries were delineated in 223 patients. One cystic artery was seen in the Calot triangle in 173 patients, and two cystic arteries were seen in the Calot triangle in 12. One artery in the Calot triangle with accessory arteries from different origins outside the Calot triangle was seen in 18 patients, and no cystic artery was identified in 20. Cystic arteries were seen in 42 (92%; 95% confidence interval: 87%, 98%) of the 48 patients who subsequently underwent cholecystectomy. The relationship between the cystic arteries and the Calot triangle was in agreement with the surgical records for all patients.
CONCLUSION
The configuration of the cystic duct and cystic arteries can be depicted preoperatively with 64-detector row CT in patients scheduled to undergo cholecystectomy.
