Two techniques of vena cava filter placement with intravascular ultrasound (IVUS) guidance have been described previously. Placement with real-time IVUS imaging requires two venous access sites, one for the filter delivery system and one for the IVUS catheter, which makes the procedure more invasive. Alternatively, a single-access technique of IVUS imaging of the vena cava requires measuring the distance from the access site to the desired location for filter placement and then delivering the filter to that distance blindly, risking filter misplacement. We describe in this article a single puncture technique that allows for real-time imaging to position the filter delivery sheath using IVUS and reduces the uncertainty of the blind positioning of the filter delivery system.
此前已描述了两种在血管内超声（IVUS）引导下放置腔静脉滤器的技术。使用实时IVUS成像进行放置需要两个静脉穿刺部位，一个用于滤器输送系统，另一个用于IVUS导管，这使得该操作更具侵入性。另外，腔静脉IVUS成像的单穿刺技术需要测量从穿刺部位到滤器放置所需位置的距离，然后盲目地将滤器输送到该距离，存在滤器放置错误的风险。我们在本文中描述了一种单穿刺技术，该技术允许使用IVUS进行实时成像以定位滤器输送鞘，并减少滤器输送系统盲目定位的不确定性。
