新型血管封堵器在心导管术后应用120例观察

目的评价新一代血管封堵器Angio-Seal STS在冠状动脉造影及介入术后股动脉封闭中的应用价值。方法对重庆医科大学附属第一医院心内科2004-09—2005-12收治的298例病人,分为血管封堵器A组(120例)和人工压迫B组(178例),观察止血成功率、止血时间、卧床时间及血管性并发症。结果A组在止血时间、卧床时间及腰背痛不适上明显低于B组(P<0·05)。在止血成功率、腹股沟皮下血肿及血管迷走神经反射方面两组差异无显著性(P>0·05)。结论Angio-Seal STS血管封堵器对股动脉穿刺点能快速、有效地止血,缩短卧床时间,且不增加血管性并发症。Angio-Seal STS特点是自身紧闭式缝合,无须已往使用Angio-Seal后放置的弹簧。

Application of vascular closure device with the new Angio - Seal STS to cardiac catheterization

Objective To evaluate the value of Vascular Closure Device(VCD)with the new Angio-Seal STS(Self-Tightening Suture)in femoral artery closure after coronary angiography(CAG)or percutaneous coronary intervention(PCI).Methods Totally 298 patients were divided into Angio-Seal STS group(group A,n=120)and manual compression group(group B,n=178).The success rate of hemostasis,the time of hemostasis,the time of bedrest and the complication rate were observed.Results Compared with group B,the time of hemostasis,the time of bedrest and the rate of distress on the waist were markedly decreased in group A(P<0.05).But there were no notable differences in the success rate of hemostasis,groin hematoma and vasovagal reflex(P>0.05).Conclusion Angio-Seal STS vascular closure derice provided a safe and effective means of obtainig rapid arterial hemostasis after cardiac catheterization.It reduces the bedrest time and discomfort without increasing complications.Angio-seal STS device has the feature of self tightening suture,and doesn't need the post-placement tension spring.
