经膈下动脉介入化疗栓塞术治疗原发性肝癌

目的观察膈下动脉形成肝癌侧枝血供的因素和几率。方法在对137例患者介入治疗中,造影寻找膈下动脉,并超选形成肿瘤血供的膈下动脉,进行化疗栓塞。结果137例患者中有21例经膈下动脉介入治疗(占15.3%),其中原发性肝癌手术切除后复发2例(9.5%),首次介入治疗出现膈下动脉供血3例(14.3%),2次或多次介入治疗后出现膈下动脉供血16例(76.2%)。结论膈下动脉是原发性肝癌的最重要侧枝供血动脉,经膈下动脉介入化疗栓塞原发性肝癌成功率高而且并发症少。

Transcatheter Arterial Chemoembolization for Hepatocellular Carcinoma Via the Inferior Phrenic Artery

Objective To investigate the factors and rate of the forming of the collateral feeding arteries from inferior phrenic artery(IPA) in hepatocellular carinoma(HCC).Methods IPA was demonstrated on angiographs in 137 patients with HCC during transcatheter arterial chemoembolization(TACE),TACE was performed through diaphragmatic inferior artery(DIA) super setectively.Results Of 137 cases,21 cases underwent TACE through DIA(15.3%),of them 2 cases were recurrent after surgical operation(9.5%),3 cases had the tumor receive blood supply from IPA at first TACE(14.3%) and 16 cases were occured after TACE tow and more times(76.2%).Conclusion Collateral branches originated from IPA are important feeding arteries in HCC,TACE of IPA can be performed with a high success rate without major complications.
