We have modified a snare technique originally described for transcolonoscopic removal of colonic polyps for the retrieval of intravascular foreign bodies. The key difference from other snare techniques is the employment of a wire snare with a crimp in its midportion that enables the formation of a loop in a plane perpendicular to the axial direction of the guiding catheter. With this technique we have quickly removed a variety of objects from the right heart and pulmonary arteries in four patients.
我们改良了一种最初用于经结肠镜切除结肠息肉的圈套技术，用于取出血管内异物。与其他圈套技术的关键区别在于使用了一种在中部有压接的金属丝圈套器，这使得能够在与引导导管轴向垂直的平面上形成一个环。通过这种技术，我们已在4例患者中迅速从右心和肺动脉取出了各种异物。
