【摘要】：目的:探討CT血管造影(CT angiography,CTA)在血管化髂骨肌瓣臨床設(shè)計(jì)中的應(yīng)用價值。方法:選取2014年8月~2015年9月,收治的12例擬行血管化髂骨肌瓣修復(fù)手術(shù)的患者。術(shù)前行CT血管造影,利用影像工作站(Philips Medical Systems),觀察并測量旋髂深動脈(deep circumflex iliac artery,DCI)起始管徑、起始點(diǎn)與雙側(cè)髂前上棘連線的成角以及起始點(diǎn)至髂前上棘的距離。依據(jù)成角的角度及距離行旋髂深動脈起始點(diǎn)體表定位,并模擬血管化髂骨肌瓣切取。結(jié)果:旋髂深動脈起始管徑(2.8±0.61)mm,旋髂深動脈起始點(diǎn)與雙側(cè)髂前上棘連線的成角(55±1.7)°,旋髂深動脈起始點(diǎn)距髂前上棘的距離為(65.1±1.24)mm。依據(jù)重建影像可以成功模擬血管化髂骨肌瓣的切取。結(jié)論:CT血管造影可以準(zhǔn)確顯示旋髂深動脈的解剖位置,能夠指導(dǎo)血管化髂骨肌瓣的制備。
[Abstract]:Objective: to evaluate the value of CT angiographyCTAs in the clinical design of vascularized iliac bone flap. Methods: from August 2014 to September 2015, 12 patients with vascularized iliac bone flap were selected. Before operation, CT angiography was performed. The diameter of deep circumflex iliac artery of deep iliac circumflex artery, the angle between the starting point and bilateral superior iliac spine and the distance between the starting point and the anterior superior iliac spine were observed and measured by using Philips Medical system. The starting point of deep iliac circumflex artery was located according to the angle and distance, and the vascularized iliac muscle flap was removed. Results: the initial diameter of deep circumflex iliac artery was 2.8 鹵0.61mm. the distance between the starting point of deep circumflex iliac artery and bilateral anterior superior iliac spine was 55 鹵1.7 擄. The distance between the starting point of deep circumflex iliac artery and anterior superior iliac spine was 65.1 鹵1.24 mm. Based on the reconstructed images, the vascularized iliac muscle flap can be successfully simulated. Conclusion the anatomical position of deep circumflex iliac artery can be accurately displayed by using VCT angiography, and it can guide the preparation of vascularized iliac muscle flap.
