【摘要】：目的:通过对比超声造影(CEUS)与增强CT(CECT)对门静脉癌栓(PVTT)的诊断敏感性、分型准确率,并比较不同类型的PVTT术后辅助治疗方案选择的差异,以探讨CEUS对PVTT的影像学意义。方法:回顾性分析我院34例PVTT患者的临床和影像学资料,全部患者均经术后病理证实。以临床病理学分型为基础,依据CEUS、CECT对癌栓侵犯门静脉的显示情况进行影像学分型。结果:CEUS、CECT诊断PVTT的敏感性分别为94.1%、91.2%,这2种方法比较差异无统计学意义(P0.05);CEUS、CECT对PVTT的分型准确率分别为93.8%、90.0%,这2种方法比较差异亦无统计学意义(P0.05)。CEUS分型和临床病理分型之间呈高度正相关(rs=0.960,P0.05),CEUS分型和CECT分型之间亦呈高度正相关(rs=0.876,P0.05)。对于合并PVTT患者术后采用的不同辅助治疗方式(化疗栓塞、化疗、放疗)而言,不同类型PVTT患者之间比较差异有统计学意义(P0.05)。结论:CEUS对PVTT的诊断敏感性高,且分型准确,与临床病理分型高度符合,故CEUS可作为PVTT治疗前评估的重要影像学方式;CEUS与CECT的诊断价值相似,临床上两者可互补以提高PVTT诊断的准确率;CEUS对PVTT的分型有利于指导术后进一步治疗。
[Abstract]:Objective: to compare the sensitivity and accuracy of contrast-enhanced CT with contrast-enhanced CT in the diagnosis of portal vein tumor thrombus (PVTT), and to compare the choice of different types of adjuvant treatment after PVTT. To explore the imaging significance of CEUS in PVTT. Methods: the clinical and imaging data of 34 cases of PVTT in our hospital were retrospectively analyzed. All the patients were confirmed by postoperative pathology. Results the sensitivity of CECT in the diagnosis of PVTT was 94.1 and 91.2, respectively. There was no significant difference between the two methods. The accuracy of CECT in the classification of PVTT was 93.8% and 90.0%, respectively. Methods there was no significant difference between P0.05U. CEUS classification and clinicopathologic classification. There was a high positive correlation between CEUS classification and CECT classification. Different adjuvant treatment methods (chemoembolization, chemoembolization) were used in patients with PVTT. In terms of chemotherapy and radiotherapy, there were significant differences among different types of PVTT patients (P 0.05). Conclusion: the sensitivity of PVTT is high, the classification is accurate, and it is highly consistent with the clinicopathologic classification. Therefore, CEUS can be used as an important imaging method to evaluate PVTT before treatment. The diagnostic value of CEUs is similar to that of CECT, and they can complement each other in clinic to improve the diagnostic accuracy of PVTT. The classification of PVTT by CEUs is helpful to guide the further treatment after operation.
