【摘要】：目的通过256层螺旋CT血管成像技术观察胆囊动脉正常解剖、起源变异,研究其对胆囊切除术前评估的临床意义。方法回顾性分析215例在我院行上腹部增强CT扫描或CTA血管造影患者的影像资料。观察胆囊动脉的起源、测量胆囊动脉横径、起源距离。结果 215例胆囊动脉中大多数是单支型,其中两支型胆囊动脉4例,共计219支胆囊动脉,男128支,女91支。正常起源于肝右动脉183支,占83.6%;起源变异36支,占16.4%。胆囊动脉正常起源和起源变异在不同性别间均无显著差异(P0.05)。对183支正常起源于肝右动脉的胆囊动脉起源距离测量,男106支,平均(33.15±11.75)mm,女77支,平均(27.54±12.94)mm,胆囊动脉正常起源距离在不同性别间具有显著差异(P0.05)。胆囊动脉横径测量,男106支,平均(1.95±0.34)mm,女77支,平均(1.92±0.34)mm,正常起源胆囊动脉横径在不同性别间无显著差异(P0.05)。结论 256层螺旋CT能明确观察胆囊动脉的正常解剖及起源变异,为胆囊术前做好评估,提供参考资料。
[Abstract]:Objective to observe the normal anatomy and origin variation of gallbladder artery by 256-slice spiral CT angiography and to evaluate its clinical significance before cholecystectomy. Methods the imaging data of 215 patients with enhanced CT or CTA angiography in upper abdomen were analyzed retrospectively. The origin of gallbladder artery was observed and the transverse diameter and origin distance of gallbladder artery were measured. Results most of the 215 gallbladder arteries were of single branch type, of which 4 were of two type, with 219 gallbladder arteries, 128 in males and 91 in females. The normal origin was 183 right hepatic artery (83.6) and the origin variation was 36 (16.4). There was no significant difference in normal origin and variation of gallbladder artery between sexes (P0.05). The origin distance of normal gallbladder artery originated from right hepatic artery was measured, male 106, mean (33.15 卤11.75) mm, female 77, mean (27.54 卤12.94) mm,. The normal origin distance of gallbladder artery was significantly different between sexes (P0.05). The mean transverse diameter of gallbladder artery was (1.95 卤0.34) mm, and (1.92 卤0.34) mm,. There was no significant difference in the transverse diameter of gallbladder artery between different sexes (P0.05). Conclusion 256-slice spiral CT can clearly observe the normal anatomy and origin variation of gallbladder artery, and provide reference materials for the evaluation of gallbladder before operation.
