胰腺癌血管侵犯的CT术前评价

Preoperative Assessment of Vascular Invasion in Pancreatic Cancer——Value of CT

目的探讨胰腺癌血管侵犯的CT分级标准。方法在CNKI及PubMed上检索并复习近10年来关于CT评价胰腺癌侵犯胰周血管的文献,对CT评价胰腺癌血管侵犯程度的价值进行综述。结果多层螺旋CT是判断胰腺癌可切除性的最佳影像学方法。目前主要的胰周血管侵犯CT分级标准包括:根据肿瘤和血管间关系的CT分级标准、根据肿瘤包绕血管程度的CT分级标准、根据管腔狭窄程度的CT分级标准及联合受侵血管狭窄程度与肿瘤包绕血管程度的CT分级标准。结论胰腺癌血管侵犯的CT分级标准还不统一,每个标准都有缺陷。

Objective To probe CT grading criteria of vascular invasion in pancreatic cancer. Methods Retrieved articles in CNKI and PubMed about value of CT in preoperative assessment of vascular invasion in pancreatic cancer last ten years. Results Multislice helical CT is considered the best imaging method to assess the invaded peripancreatic vessels in pancreatic cancer. There are different CT criteria of vascular invasion in pancreatic cancer based on extension of hypodense tumor and its relation to blood vessels, on the degree of circumferential contiguity of tumor to vessel, on the degree of lumen stenosis, and on the degree of contiguity between tumor and vessels combined vascular caliber. Conclusion CT grading criteria are not uniform, each one has defects.
