目的:比较CTA与DSA对胰腺癌血管侵犯估计的应用价值。方法:对56例胰腺癌的CTA和DSA表现进行分析。结果:56例中22例患者无血管受累,CTA与DSA检查结果及手术结果均一致。血管受累的34例中,25例CTA与DSA结果一致,9例不一致。结论:与DSA相比,CTA有非侵袭性和高敏感性的优点,在胰腺癌术前评估中有着更大的价值。
Objective: To compare the value of CTA and DSA in the estimation of vascular invasion in pancreatic cancer. Methods: The clinical manifestations of CTA and DSA in 56 cases of pancreatic cancer were analyzed. Results: Twenty-two of 56 patients had no vascular involvement. The results of CTA and DSA were consistent with those of surgery. Among the 34 cases of vascular involvement, 25 cases of CTA were consistent with DSA results and 9 cases were inconsistent. Conclusion: Compared with DSA, CTA has the advantages of noninvasiveness and high sensitivity, which is of great value in the preoperative evaluation of pancreatic cancer.
