| 目的 探讨三维DSA显示子宫动脉（UA）开口位置的价值。方法 选择90例接受子宫动脉栓塞术患者，经导管分别选择入左、右髂内动脉，行三维DSA血管造影，然后对图像进行三维后处理，每间隔5°旋转，采集三维图像，观察UA最佳显示角度范围;统计UA起源及开口角度，以臀上动脉开口为定位点，测量UA开口距臀上动脉开口距离。结果 在对侧斜位和同侧斜位＞30°~60°显示UA开口最好;116支（116/180，64.44%）UA起源于髂内动脉前干；33支（33/180，18.33%）起源于臀下阴部干；17支 （17/180，9.44%）起源于阴部内动脉；10支（10/180，5.56%）起源于髂内动脉主干；4支（4/180，2.22%）起源于臀上动脉。UA与起源动脉夹角0~30°为19支，占10.56%（19/180）；＞30°~60°70支，占38.89%（70/180）；＞60°~90°74支，占41.11%（74/180）；＞90°~120°8支，占4.44%（8/180）；＞120°~150°5支，占2.78%（5/180）；＞150°~180°4支，占2.22%（4/180）。UA开口至臀上动脉开口距离为3.04~18.31 mm，平均（11.71±4.28）mm。结论 三维DSA可较好地显示子宫动脉起源、开口角度以及距臀上动脉的距离。 |

| Objective To explore the value of three-dimensional DSA (3D-DSA) in displaying the location of the origin of uterine artery. Methods A total of 90 female patients underwent uterine artery (UA) embolization were enrolled. The bilateral internal iliac artery catheterization were performed by 3D-DSA, then the images were reconstructed in every 5 degree interval to choose the optimum range of viewing angle. The origination and the degree of the origin artery and UA were calculated. The distance between the origin of UA and superior glutea artery which was identified as the locating point was measured. Results Bilateral and contralateral oblique position of ＞30°-60°were the optimal projection positions of UA. Totally 64.44% (116/180) of UA originated from the anterior trunk of internal iliac artery, 18.33% (33/180) originated from the inferior gluteal trunk, 9.44% (17/180) originated from the internal pundenal artery, 5.56% (10/180) originated from internal iliac artery, and 2.22% (4/180) originated from the superior gluteal artery; 10.56% (19/180) of the angle of the origin artery and UA were 0-30°, 38.89% (70/180) were ＞30°-60°, 41.11% (74/180) were ＞60°-90°, 4.44% (8/180) were ＞90°-120°, 2.78% (5/180) were ＞120°-150°, 2.22% (4/180) were ＞150°-180°. Distance between the origin of UA and superior gluteal artery was 3.04-18.31 mm, average was (11.71±4.28)mm. Conclusion 3D-DSA can clearly display the origination, viewing angle and the distance away from superior gluteal artery. |
