恶性肿瘤引起下腔静脉梗阻血管内支架治疗的临床应用

Clinical application of self-expendable metallic stent implantation in malignant inferior vena cava obstruction

目的探讨恶性肿瘤引起下腔静脉梗阻血管内支架治疗的临床效果。方法16例下腔静脉梗阻患者中,原发性肝癌7例,肝转移癌6例,胃癌2例,胰腺癌腹膜后淋巴结转移1例(其中男性9例,女性7例,年龄40～70岁)。均造成下腔静脉的完全或部分梗阻,采用经皮股静脉穿刺行血管内支架治疗。结果16例患者均一次成功植入血管支架。下腔静脉梗阻症状明显改善。全部病例均无严重并发症。结论血管支架植入术可迅速缓解下腔静脉恶性梗阻的临床症状,是治疗恶性下腔静脉梗阻有效的姑息性治疗方法。

Objective To evaluate the therapeutic effect of metallic Z-type self-expendable stent in malignant vena cava inferior obstruction. Method A total of 16 patients were enrolled, male 9, female 7, aged 40 - 70 years, including 7 cases of primary hepatocarcinoma, 6 cases of metastases of liver, 2 cases of gastric carcinoma and 1 case of pancreatic cancer. Complete or partial occlusion of vena cava inferior were existed in these patients and the treatment of percutancous endovascular stent implantation were performed. Results The intravascular stent were successfully implanted in all of the 16 cases and no serious complications were found. Conclusion The intravascular stent implantation is an effective approach for relieving symptoms caused by malignant vena cava inferior obstruction.
