Application of Color Doppler Flow Imaging in Portal Vein Chemotherapy by Ultrasound Guided Percutaneous Transhepatic Portal Injection / 中华超声影像学杂志

ABSTRACT

To evaluate the role of color Doppler flow imaging in the portal vein chemotherapy by ultrasound guided percutaneous transhepatic portal injection, the blood supply of liver tumor and portal hemodynamics were studied in 15 patients with primary hepatic carcinoma and one patient with secondary hepatic carcinoma. The continuous wave in the lesion and forward continuous wave in the portal vein seen by pulsed Doppler in nine cases, were indications for this therapeutic method. The distribution of the drugs in the liver could be observed by color Doppler flow imaging when injection was being done. The therapeutic efficacy of portal vein chemotherapy in liver tumor may be evaluated by color Doppler folw imaging and puncture biopsy.
