Micropuncture versus traditional puncture technique in the treatment complications of lower extremity arteriosclerosis occlusion / 中华普通外科杂志

ABSTRACT

Objective To compare the clinical results of micropuncture technique and traditional puncture technique in the treatment of lower extremity arteriosclerosis occlusion.Methods From January 2007 to February 2012,862 patients of lower extremity arteriosclerosis occlusion were treated by endovascular technology,385 patients ( 463 limbs ) by 21-G micropuncture technique and 477 patients ( 586 limbs ) by traditional 18-G puncture technique.Access sites were managed with manual pressure hemostasis or a vascular closure device.Primary endpoints included groin hematoma ( ≥ 2 cm),pseudoaneurysm,iatrogenic arteriovenous tistula,retroperitoneal hematoma,vascular perforation requiring repair and blood flow limited dissection.Results Patients assigning to undergo micropuncture technique were at higher risk,there was a significant shorter puncture time required for micropuncture technique vs.traditional puncture technique,(3.2 ± 2.3 vs.5.1 ± 3.2,P ＜ 0.05 ),the overall access site complications rate was lower in micropuncture group ( 6.2％ vs.6.7％,x2 =7.91,P ＜ 0.005 ).Conclusions In lower extremity arteriosclerosis occlusion treatment,arterial access can be completed by micropuncture which was safer and more effective than traditional puncture technique.
