目的:探讨研究宫颈癌子宫动脉血管网的方法及其临床意义。方法:用15%的过氯乙烯填充剂对一例宫颈癌离体子宫标本行子宫动脉和卵巢动脉分色灌注并铸型。分别于灌注前后行64层螺旋CT薄层扫描,并以最大密度投影法(MIP)和容积再现(VR)行三维重建。结果:(1)铸型和CT三维重建的宫颈癌子宫动脉血管网模型均可清晰的显示病变部位的血管供应及分布情况、子宫动脉及其分支的走行以及与卵巢动脉的关系;(2)利用CT薄层扫描重建的可视化模型可以从多方面清楚的显示病灶的大小及浸润范围。结论:应用血管铸型和CT薄层扫描技术可成功构建宫颈癌子宫动脉血管网模型,并可了解宫颈癌病灶的浸润范围及其血供特点等,对宫颈癌的诊断和治疗有一定的临床价值。
Objective: To explore the method of studying the uterine artery network of cervical cancer and its clinical significance. Methods: Uterine artery and ovarian artery were isolated and cast with a 15% perchlorovinyl filler on an isolated uterus specimen of cervical cancer. Sixty-four spiral CT thin films were scanned before and after perfusion. Three-dimensional reconstruction was performed by maximum density projection (MIP) and volume rendering (VR). Results: (1) The uterine artery network model of cervical cancer with three-dimensional reconstruction of the mold and CT can clearly show the vascular supply and distribution of the diseased part, the movement of the uterine artery and its branches, and the relationship with the ovarian artery. (2) The visualization model using CT thin-layer scan reconstruction can clearly show the size and infiltration range of lesions in many aspects. Conclusion: The uterine artery vascular network model of cervical cancer can be successfully constructed by using vascular casting and CT thin-layer scanning, and the infiltration range and blood supply characteristics of cervical cancer can be understood. There is a certain clinical diagnosis and treatment of cervical cancer value.
