The effect of puncture technique in thoracic endovascular aortic repair with abdominal aortic aneurysm / 中国医师进修杂志

ABSTRACT

Objective To evaluate puncture technique in thoracic endovascular aortic repair with abdominal aortic aneurysm and assess the feasibility and safety of using a pre-close technique for puncture and closure of femoral access sites. Methods From May 2010 to August 2013, the pre-close technique which involved two 6 F per-close ProGlide devices deployed in the femoral artery before upsizing to a 18-25 F sheath and one or two deployed before upsizing to a 14-16 F sheath were applied to 42 patients with abdominal aortic aneurysm (group A). Forty-seven patients using surgical femoral cutdown from December 2006 to April 2010 were enrolled into group B. The rate of technical success, time from procedure to the aortic delivery, operation time, low limb braking time, local complication, time from procedure to discharge, local vascular diameter after 3 months was evaluated and compared between two groups. Results There was no significant difference in endograft external diameter between two groups ( P>0.05). The rate of technical success was 97.62%(41/42) in group A and 95.74%(45/47) in group B, and there had no significant difference (P>0.05). Time from procedure to the aortic delivery, operation time and time from procedure to discharge in group A were significantly shorter than those in group B (21.79 ± 5.79) min vs. (41.37 ± 11.79) min, (127.66±37.83) min vs. (157.84±42.71) min, (6.59±1.89) d vs. (9.14±2.57) d, P0.05. Conclusion The puncture technique with per-close ProGlide is safe and effective in percutaneous endovascular aortic repair which can be adopted as an alternative technique of surgical femoral cutdown approach in patients with abdominal aortic aneurysm.
