目的 评价彩色多普勒成像诊断胰腺癌周围血管受侵情况的准确性。方法 应用彩超对 4 7例胰腺癌病人胰周血管受侵情况进行预测评估 ,并与外科结果进行了比较。结果 通过手术的 4 7例病人受侵血管的诊断 ,彩超的敏感性、特异性和准确性分别是 80 %、91%和 85%。阳性和阴性预测值分别是 91%和 80 %。结论 彩超在评价胰腺癌血管受侵时有一定敏感性和高度特异性。当彩超检测到有血管包裹时 ,可以做出不可切除的肯定诊断 ,可以避免进一步的诊断过程。
Objective To evaluate the accuracy of color Doppler imaging in the diagnosis of peripheral vascular invasion of pancreatic cancer. Methods Forty-seven patients with pancreatic cancer who underwent periurethral vascular invasion were prospectively assessed by color Doppler ultrasound and compared with surgical findings. Results The sensitivity, specificity and accuracy of color Doppler ultrasound were 80%, 91% and 85%, respectively, for the diagnosis of invasive blood vessels in 47 patients. The positive and negative predictive values were 91% and 80%, respectively. Conclusion Color Doppler ultrasound in the evaluation of vascular invasion of pancreatic cancer has a certain sensitivity and high specificity. When the color Doppler ultrasound detects a blood vessel package, you can make a positive diagnosis of unresectable, to avoid further diagnosis.
