A new transhepatic endoprosthesis, a so-called screw endoprosthesis with a spiral-shaped elevation to prevent dislodgement, is presented. The elevation is created by a silver wire wound around the endoprosthesis. Further, the wire may be used as a marker for radiotherapy or for taking biopsies, and it makes it easier to control the position of the endoprosthesis. The screw endoprosthesis was used in 22 patients, including 9 patients with high strictures in which dislodgement is known to be frequent, and 2 patients in whom previously inserted ordinary endoprostheses had been dislodged. The insertion of the screw endoprosthesis was easy. The complication rate was similar to that of ordinary transhepatic endoprosthesis. No cases of dislodgement were observed.
本文介绍了一种新型经肝内支架，即所谓的螺旋内支架，其带有螺旋形凸起以防止移位。该凸起由缠绕在内支架周围的银线制成。此外，该银线可用作放射治疗或活检的标记物，并且便于控制内支架的位置。螺旋内支架应用于22例患者，其中包括9例已知移位频繁的高位狭窄患者以及2例先前植入的普通内支架已发生移位的患者。螺旋内支架的插入操作简便。并发症发生率与普通经肝内支架相似。未观察到移位病例。
