【摘要】： 本研究通过脾动脉CTA重建图像,观察研究了脾动脉主干的走行及其与周围组织关系。鉴于国内尚缺乏脾动脉三维重建的研究资料,对于脾动脉与胰腺的解剖关系也无详细研究,本研究通过影像学方法观测脾动脉的局部影像解剖资料以期为临床胰腺外科手术、脾外科手术、腹腔镜手术以及医学影像学提供解剖学资料。通过对脾动脉主干的三维重建,清楚地显示血管图像以及与周围组织的关系,研究中观察到:脾动脉主干及其分支走形较不规则,远端与胰尾、脾门关系密切且复杂。在腹部多种手术中需仔细处理脾动脉的解剖关系,也是腹腔镜手术中需要重点处理的内容。但是,CTA对于研究脾叶动脉及其分支尚不甚理想。VR能容易地重建脾动脉主干及其较大的分支,但是由于需要人工设置CT值范围,因此不能客观地反映血管狭窄情况,临床应用受到限制。尽管如此,CTA能显示脾动脉及其周围多个血管的关系、腹部内脏器官的形态结构、毗邻关系,立体感强。随着后处理软件的发展,CTA将广泛应用于血管显像及病变观察,甚至有望替代DSA。
[Abstract]:In this study, CTA images of splenic artery were used to observe and study the course of splenic artery trunk and its relationship with surrounding tissues. In view of the lack of three-dimensional reconstruction of splenic artery in China, there was no detailed study on the anatomical relationship between splenic artery and pancreas. The purpose of this study was to provide anatomical data for clinical pancreatic surgery, splenic surgery, laparoscopic surgery and medical imaging. Through the three-dimensional reconstruction of the main trunk of the splenic artery, the images of the blood vessels and their relationship with the surrounding tissues were clearly displayed. In the study, it was observed that the main trunk of the splenic artery and its branches were irregular in shape, the distal part and the tail of the pancreas. The splenic portals are closely related and complex. The anatomical relationship of the splenic artery needs to be carefully handled in various abdominal operations. But CTA is not ideal for studying the splenic lobe artery and its branches. VR can easily reconstruct the splenic artery trunk and its larger branches, but because of the need to set the CT value range manually, Therefore, it can not objectively reflect the situation of vascular stenosis, and its clinical application is restricted. Nevertheless, CTA can show the relationship between splenic artery and its surrounding vessels, the shape and structure of abdominal visceral organs, and the adjacent relationship. With the development of post-processing software, CTA will be widely used in vascular imaging and pathological observation, and may even replace DSA.
