With the development of ultrasonic diagnostic techniques in recent years, ultrasound-guided placement of inferior vena cava (IVC) filters has been widely used in clinics, and satisfactory results have been achieved. Our study aims to observe the accuracy of hand-carried ultrasound-guided retrievable vena cava filter placement, evaluate the feasibility and safety of this new method, and provide a scientific and effective interventional method and clinical data to prevent acute pulmonary embolism (PE) after battle injury of limbs.
Two hundred patients with post-traumatic thrombosis of the extremities were enrolled. The renal vein was located under the guidance of hand-carried ultrasound. The retrievable filter was fixed 1-2 cm below the opening of the renal vein. The self-expanding filter was used after the filter's position was confirmed by injecting the contrast agent under the digital subtraction angiography (DSA) fluoroscopy.
All the 200 patients underwent the operation successfully. The position of the hand-carried ultrasound localizer was consistent with the DSA localizer. All the filters were expanded smoothly. No complications related to the operation occurred.
The study concluded that the hand-carried ultrasound-guided retrievable vena cava filter placement has a high success rate and can prevent acute PE after limbs' battle injury.
近年来随着超声诊断技术的发展，超声引导下腔静脉滤器置入术在临床上已广泛应用，并取得了满意的效果。本研究旨在观察便携式超声引导下可回收腔静脉滤器置入的准确性，评估该新方法的可行性和安全性，为预防肢体战伤后急性肺栓塞（PE）提供科学有效的介入方法及临床资料。
选取200例创伤后肢体血栓形成患者。在便携式超声引导下定位肾静脉。将可回收滤器固定于肾静脉开口下方1-2cm处。在数字减影血管造影（DSA）透视下注入造影剂确认滤器位置后使用自膨胀滤器。
200例患者均成功完成手术。便携式超声定位器与DSA定位器位置一致。所有滤器均顺利展开。未发生与手术相关的并发症。
本研究得出结论，便携式超声引导下可回收腔静脉滤器置入成功率高，可预防肢体战伤后急性PE。
