1.2 手术方法
图1 使用血管缝合器的手术步骤Figure 1 Suture steps for suture-mediated vascular closure device A, the diameter of brachial artery measured by angiography was 6.48 mm; B, push the vascular closure device forward gently until pulsatile blood spray appears in the observation hole, then stop the advancement and keep the device in place (pay attention to observation hole); C, complete the plunger depression and remove the device while pulling tension on the blue Prolene; D, tighten the vascular suture knot and observe the bleeding in the puncture site; E, after the suture procedure was completed, the bleeding at the puncture point stopped. |
