目的 探讨彩色多普勒血流显像在胰头癌、胆管远端癌时胰周血管受侵的应用价值。方法 根据恶性肿瘤和相邻血管组织 ,即肠系膜上动脉 (SMA)、肠系膜上静脉 (SMV)和门静脉 (PV)的关系 ,设计胰腺多普勒评分 (PDS)为 4个等级 :1分 ,2分 ,3分和 4分。检测 16例胰头癌和 2例胆管远端癌患者与CT比较。结果 显示PDS评分 1、2、3分者证实符合例数为 9例 (9/ 10例 ) ,PDS评分为4分者 ,证实符合例数为 8例 (8/ 8例 ) ,总的准确例数为 17例 (17/ 18例 )。CT的符合例数为 14例 (14/18例 ) ,与CT相比 ,彩色多普勒检测对胰头癌和远端胆管癌时胰周血管受侵的应用价值更高。结论应用彩色多普勒血流显像对胰头癌和远端胆管癌时胰周血管受侵的检查方法是一种比较理想的方法。
Objective To investigate the value of color Doppler flow imaging in detecting pancreatic vascular invasion in pancreatic head cancer and distal bile duct cancer. Methods The pancreatic Doppler Score (PDS) was designed based on the relationship between malignant tumors and adjacent vascular tissues, namely superior mesenteric artery (SMA), superior mesenteric vein (SMV), and portal vein (PV): 4 points: 1 point, 2 points Points, 3 points and 4 points. Detection of 16 cases of pancreatic head cancer and 2 cases of distal bile duct cancer compared with CT. The results showed that the PDS scores of 1, 2 and 3 were confirmed as 9 cases (9/10 cases), PDS scores were 4 points, and the number of confirmed cases was 8 cases (8/8 cases). The number was 17 cases (17/18 cases). The number of matched cases of CT was 14 cases (14/18 cases). Compared with CT, color Doppler detection had higher value in the application of pancreatic vascular invasion to pancreatic head cancer and distal bile duct cancer. Conclusion The application of color Doppler flow imaging in the detection of pancreatic vascular invasion in pancreatic head cancer and distal bile duct cancer is an ideal method.
