【摘要】：目的利用基于CT血管成像(CTA)三維重建技術(shù)構(gòu)建的子宮腺肌病子宮動(dòng)脈血管網(wǎng)數(shù)字化三維模型,探討子宮腺肌病血供特點(diǎn)。方法選取2009年9月至2016年7月在南方醫(yī)科大學(xué)南方醫(yī)院接受CTA檢查的子宮腺肌病患者84例,采集其CTA原始數(shù)據(jù)集,構(gòu)建子宮腺肌病子宮動(dòng)脈血管網(wǎng)數(shù)字化三維模型,并通過調(diào)整閾值改變血管網(wǎng)顯示密度,分析子宮腺肌病血供特點(diǎn),即血供來(lái)源、血供類型、血流豐富程度等。結(jié)果 (1)本研究成功構(gòu)建了84例子宮腺肌病子宮動(dòng)脈血管網(wǎng)數(shù)字化三維模型,可清晰的呈現(xiàn)子宮動(dòng)脈及子宮肌層、子宮腺肌病病灶的血管網(wǎng),三維立體觀察子宮腺肌病血供特點(diǎn)。(2)子宮腺肌病血供來(lái)源為雙側(cè)子宮動(dòng)脈、雙側(cè)子宮動(dòng)脈和一側(cè)卵巢動(dòng)脈、雙側(cè)子宮動(dòng)脈和雙側(cè)卵巢動(dòng)脈所占的比例分別為89.28%(75/84)、5.96%(5/84)、4.76%(4/84)。(3)子宮腺肌病血供類型為Ⅰ型(雙側(cè)子宮動(dòng)脈供血為主型)、Ⅱ型(雙側(cè)子宮動(dòng)脈供血均衡型)、Ⅲ型(一側(cè)子宮動(dòng)脈供血為主型)所占的比例分別為38.10%(32/84)、40.48%(34/84)、21.43%(18/84)。(4)子宮腺肌病血流豐富程度為富血流型、一般血流型、乏血流型所占的比例分別為69.05%(58/84)、20.24%(17/84)、10.71%(9/84)。結(jié)論利用CTA原始數(shù)據(jù)集和數(shù)字化三維重建技術(shù)可構(gòu)建出子宮腺肌病子宮動(dòng)脈血管網(wǎng)數(shù)字化三維模型,也可進(jìn)行血供特點(diǎn)分析,為子宮動(dòng)脈栓塞術(shù)的個(gè)體化應(yīng)用和臨床教學(xué)提供參考。
[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，
