作者对1991年～1993年所放置的长期静脉导管进行回顾性分析,以评价放置过程出现的问题,近期及远期并发症,感染发生率及导管寿命方面存在的差异。209例共放置253条导管,其中介入放射学方法为102例120条导管,余107例、133条导管经外科方法置入。 结果表明,102例介入放射学方法均首次置管成功,而外科方法有6例(4.5％)失败,其中5例在第二次应用介入放射学法放置时,静脉造影发现原来位 The authors retrospectively analyzed long-term venous catheters placed between 1991 and 1993 to evaluate the differences in placement problems, recent and long-term complications, incidence of infection, and catheter life. A total of 253 cases were placed in 209 cases, of which 102 cases were involved in radiography, 120 cases were catheterized, and the remaining 107 cases and 133 catheters were surgically implanted. The results showed that 102 cases of interventional radiology were the first successful catheterization, and surgical methods in 6 cases (4.5%) failed, of which 5 cases were placed in the second interventional radiography, venography found that the original
