下腔静脉恶性梗阻的支架介入治疗

目的 评价下腔静脉恶性梗阻支架介入治疗的疗效。方法 对36例下腔静脉恶性梗阻患者采用Z形自膨胀式金属支架治疗。术前、术后对患者下腔静脉闭塞、狭窄段内径、患者梗阻症状的积分进行比较。术后1周采用CT增强扫描对比观察。结果36例下腔静脉闭塞、狭窄段长度为3.0～14.2cm(中住值为7.3cm),下腔静脉狭窄段内径由术前0～0.6cm(中位值为0.3cm),扩张至术后内径1.2～2.1cm(中位值为1.5cm)(Z=-54.435,P<0.0001),二者比较差异有显著性。共用支架47个,支架释放成功率100％。结论 Z形自膨胀式金属支架介入治疗是下腔静脉恶性梗阻有效姑息的治疗方法。

INTERVENTIONAL TREATMENT OF STENTS IN MALIGNANT OBSTRUCTION OF INFERIOR VENA CAVA

Objective To evaluate the effectiveness of endovascular deployment of metallic Z - type self -expandable stents in treating the patients with inferior vena cava(IVC) malignant obstruction. Methods 36 patients with IVC obstruction were enrolled in this study. The diameter of stenotic segment and the scores of patients' IVC syndrome were compared before and after stents placement. The enhanced CT scans were performed one week after operation. Results There were 36 patients. The lengths of IVC stenosis were 3.0- 14.2cm( median length was 7. 3cm). The diameter of stenotic segment of IVC was increased from 0 -0.6cm(median length was 0.3cm)to 1.2 - 2. lcm(median length was 1. 5cm)(Z = - 54.435, P<0.0001) . There were 47 stents being precisely placed. Technical successful rate of stents placement was 100 % . Conclusion Endovascular deployment of metallic Z - type self - expandable stents was an effective palliative treatment for patients with IVC malignant obstruction.
