血管内导管打结在血管造影并发症中是严重的,但不常见。Syme(1967)报导用手术解除动脉内导管打结。文献已报导4例在透视监视下用非手术使打结导管解脱的技术。Young 和Maurer 处理1例经股动脉插管的5号法国聚乙烯导管打结。使导管由暂时性静置,再快速推动使结松开和增大,导丝进入结内,然后抽拉导管和导丝入髂总动脉使结解开。Hawkins 和Tonkin 处理1例J 形6号法国导管打解病例,用直接转向导丝解脱导管结。Chinichian 等处理1例8号法国headhunter导管打结,经对侧股动脉插入第二支8号法国导管穿过导管结使之解脱的方法。Thomas 和Sievers处理1例7号法国headhunter 导管打结。经对侧股动脉插入猪尾样导管,导入可转向导丝,使其能
Endovascular catheterization is serious but not uncommon in angiographic complications. Syme (1967) reported surgical removal of intra-arterial catheter kinks. The literature has reported 4 cases of non-surgical under the fluoroscopy in the knotted catheter release technique. Young and Maurer treated 1 French Polyethylene catheter cannulated via femoral artery. The catheter from a temporary rest, and then quickly push the knot to open and increase the guide wire into the knot, and then pull the catheter and the guide wire into the common iliac artery to open the knot. Hawkins and Tonkin treated one case of French Type 6 French catheter to resolve the case with a direct steering guidewire to release the catheter junction. Chinichian and other treatment of a case of No. 8 French headhunter catheter knot, the contralateral femoral artery insertion of a second French catheter through the catheter junction so that the release of the method. Thomas and Sievers handled 1 case of French Headhunter Catheter Knot 7. The contralateral femoral artery insertion of pig tail-like catheter into the guide wire can be turned to enable it
