【摘要】：目的利用基于CT血管成像(CTA)三维重建技术构建的子宫腺肌病子宫动脉血管网数字化三维模型,探讨子宫腺肌病血供特点。方法选取2009年9月至2016年7月在南方医科大学南方医院接受CTA检查的子宫腺肌病患者84例,采集其CTA原始数据集,构建子宫腺肌病子宫动脉血管网数字化三维模型,并通过调整阈值改变血管网显示密度,分析子宫腺肌病血供特点,即血供来源、血供类型、血流丰富程度等。结果 (1)本研究成功构建了84例子宫腺肌病子宫动脉血管网数字化三维模型,可清晰的呈现子宫动脉及子宫肌层、子宫腺肌病病灶的血管网,三维立体观察子宫腺肌病血供特点。(2)子宫腺肌病血供来源为双侧子宫动脉、双侧子宫动脉和一侧卵巢动脉、双侧子宫动脉和双侧卵巢动脉所占的比例分别为89.28%(75/84)、5.96%(5/84)、4.76%(4/84)。(3)子宫腺肌病血供类型为Ⅰ型(双侧子宫动脉供血为主型)、Ⅱ型(双侧子宫动脉供血均衡型)、Ⅲ型(一侧子宫动脉供血为主型)所占的比例分别为38.10%(32/84)、40.48%(34/84)、21.43%(18/84)。(4)子宫腺肌病血流丰富程度为富血流型、一般血流型、乏血流型所占的比例分别为69.05%(58/84)、20.24%(17/84)、10.71%(9/84)。结论利用CTA原始数据集和数字化三维重建技术可构建出子宫腺肌病子宫动脉血管网数字化三维模型,也可进行血供特点分析,为子宫动脉栓塞术的个体化应用和临床教学提供参考。
[Abstract]:Aim to explore the characteristics of uterine adenomyosis blood supply by using a digital three-dimensional model of uterine arterial vascular network based on CT angiography (CTA) 3D reconstruction technique. Methods from September 2009 to July 2016, 84 patients with adenomyosis who underwent CTA examination in Southern Hospital of Southern Medical University were selected. The original CTA data sets were collected and a three-dimensional digital model of uterine artery network of adenomyosis was constructed. By adjusting the threshold value to change the display density of vascular network, the characteristics of blood supply in adenomyosis were analyzed, that is, the source of blood supply, the type of blood supply, the degree of blood flow and so on. Results (1) the digital three-dimensional model of uterine artery vascular network in 84 cases of adenomyosis was successfully constructed in this study, which could clearly present the vascular network of uterine artery and myometrium, and the lesion of uterine adenomyosis. (2) the blood supply of adenomyosis was derived from bilateral uterine artery, bilateral uterine artery and one ovarian artery. The proportion of bilateral uterine artery and bilateral ovarian artery were 89.28% (75 / 84) and 5.96% (5 / 84) respectively. 4.76% (4 / 84). (3) of adenomyosis were type 鈪，
