肝癌手术后经化疗泵肝动脉二氧化碳超声造影

Enhancement of Ultrasonic Angiography of CO2 Contrast via Indwelling Hepatic Arterial A-Port after Resection of Hepatic Tumor

目的:探讨肝癌术后经化疗泵肝动脉超声造影的意义。方法:对24例肝癌切除术后行经肝动脉内留置化疗泵CO2 超声增强造影。结果:增强造影对≤3cm肝癌的检出率明显高于常规超声(P<0 01)。同时 ,还可以提供复发癌灶的病理血供 ,疗效评判及PEI治疗。结论:对肝癌切除术后留置化疗泵者应常规进行CO2

Objective:To probe the significance of ultrasonic angiography of CO2 contrast via indwelling hepatic arterial A-Port after resection of hepatic tumor Methods: Twenty-four patients were examined by ultrasonic (US) angiography of CO2 microbubbles injected via indwelling hepatic arterial A-Port after resection of hepatocellular carcinoma (HCC) Results: It demonstrated that it was more sensisitive for detecting recurrent HCC less than 3cm in diameter than conventional US (P<0 01) Meanwhile, it could demonstrate the vascular patterns of the tumor and assess the therapeutic effect and to be treated with percutaneous ethanol injection (PEI) Conclusion: It is suggested that US with CO2 microbubbles can be used routinely in patients with indwelling arterial A-Port after removal of HCC
