目的 探讨利用CT血管成像术(CTA)原始数据集构建的在体骨盆及腹盆腔动脉血管网数字化三维模型在子宫动脉栓塞术(UAE)入路规划中的应用.方法 基于CTA检查获取1例子宫肌瘤患者的原始二维断层图像数据集,利用Mimics 10.01软件分别对在体骨盆、腹盆腔动脉血管网进行三维重建并配准融合,测量各级动脉长度、分叉角度及相对位置,并进行UAE术前的入路规划.结果 本研究构建的在体骨盆及腹盆腔动脉血管网数字化三维模型可以清楚地显示腹主动脉、双侧髂总动脉、左右髂外动脉、左右髂内动脉及其多级分支.右侧子宫动脉在臀下动脉开口以下15.91 mm处发出,左侧子宫动脉在臀下动脉开口以下15.21 mm处发出,均与膀胱上动脉及阴部内动脉相邻.同时,能精确测量各级动脉的长度及分叉角度,腹主动脉分叉位于第5腰椎体上缘,角度为66.58°;右侧髂内、外动脉分叉角度为46.23°,右侧髂总动脉长度为51.43 mm;左侧髂内、外动脉分叉角度为36.45°,左侧髂总动脉长度为67.50 mm.根据术前的入路规划,导丝越过臀下动脉至其下方15.00 mm处旋转数字减影血管造影术(DSA)球管,可以较清楚地显示子宫动脉开口向外,转动导丝,比较容易进入子宫动脉.结论 基于CTA数据集,利用三维重建软件,可以构建出符合临床要求的在体骨盆及腹盆腔动脉血管网数字化三维模型,为子宫动脉介入手术前的入路规划提供依据.
目的 探討利用CT血管成像術(CTA)原始數據集構建的在體骨盆及腹盆腔動脈血管網數字化三維模型在子宮動脈栓塞術(UAE)入路規劃中的應用.方法 基于CTA檢查穫取1例子宮肌瘤患者的原始二維斷層圖像數據集,利用Mimics 10.01軟件分彆對在體骨盆、腹盆腔動脈血管網進行三維重建併配準融閤,測量各級動脈長度、分扠角度及相對位置,併進行UAE術前的入路規劃.結果 本研究構建的在體骨盆及腹盆腔動脈血管網數字化三維模型可以清楚地顯示腹主動脈、雙側髂總動脈、左右髂外動脈、左右髂內動脈及其多級分支.右側子宮動脈在臀下動脈開口以下15.91 mm處髮齣,左側子宮動脈在臀下動脈開口以下15.21 mm處髮齣,均與膀胱上動脈及陰部內動脈相鄰.同時,能精確測量各級動脈的長度及分扠角度,腹主動脈分扠位于第5腰椎體上緣,角度為66.58°;右側髂內、外動脈分扠角度為46.23°,右側髂總動脈長度為51.43 mm;左側髂內、外動脈分扠角度為36.45°,左側髂總動脈長度為67.50 mm.根據術前的入路規劃,導絲越過臀下動脈至其下方15.00 mm處鏇轉數字減影血管造影術(DSA)毬管,可以較清楚地顯示子宮動脈開口嚮外,轉動導絲,比較容易進入子宮動脈.結論 基于CTA數據集,利用三維重建軟件,可以構建齣符閤臨床要求的在體骨盆及腹盆腔動脈血管網數字化三維模型,為子宮動脈介入手術前的入路規劃提供依據.

Objective To investigate the construction and significance of in vivo pelvis and abdominal-pelvic arterial vascular network in digital three-dimensional (3D) model for uterine artery embolization (UAE) in the application of surgical approach planning based on computerized tomographic angiography(CTA).Methods A series of digital imaging and communications in medicine 3.0 (Dicom 3.0) were obtained from a woman with myoma of uterus by CTA scanning.Then the software Mimics Version 10.01 was used to construct the pelvic and the arterial vascular network 3D model.Results The digital model could clearly display the abdominal aorta,bilateral common iliac arteries,left and right external iliac artery,internal iliac artery and its branches around the stage ; the right uterine artery emitted in the inferior gluteal artery opening below 15.91 mm,the left uterine artery in inferior gluteal artery below the opening of 15.21 mm,the adjacent artery of internal pudendal artery.At the same time,the artery length and angle of bifurcation were accurately measured.The bifurcation angle of abdominal aorta in fifth lumbar vertebral body edge,was 66.58°,the bifurcation angle of right internal iliac artery was 46.23°,the length of right common iliac artery was 51.43 mm,the bifurcation angle between left and external internal iliac artery was 36.45°,the length of left common iliac artery and 67.50 mm.According to the preoperative approach planning,guided wire across the inferior gluteal artery to the lower 15.00 mm and rotating digital subtraction angiography(DSA) tube,could clearly display the uterine artery opening outward by rotating guide wire,which was relatively easy to enter the uterine artery.Conclusion The female pelvic arterial network model in vivo could be successfully constructed by using Mimics Version 10.01 software with database collected through CTA,which may contribute to the materialization of digital models and be used for preoperative surgical simulator.
