ABSTRACT
PURPOSE:
To evaluate the usefulness of placement of self-expandable stents in hemodialytic shunt-relatedsubclavian vein stenosis. MATERIALS ANDMETHODS:
Self-expandable metallic stent was placed in nine patients withhemodialytic shunt-related subclavian vein stenosis. In seven cases, angioplasty was attempted before stentplacement; in five, stents were placed immediately after failed angioplasty; and in two, due to restenosis afterangioplasty. Procedures involved a 10mm diameter, 7-10cm length Wallstent in eight cases, and a 10mm diameter, 8cm length Hanaro stent in one. In all cases, clinical follow-up, which included physical examination and themeasurement of venous resistance pressure during hemodialysis, was performed. The follow-up period was between 5months and 1 year 7 months. Repeated intervention was performed if restenosis was detected.RESULTS:
The stenoticsites were in eight cases the site of a previous subclavian venous line, and in one, the site of anatomicnarrowing at the thoracic inlet of the subclavian vein. The technical success rate was 100%; a resultingcomplication was stent migration into the right atrium in one case in which a Hanaro stent had been used; this wasremoved by snaring. During follow-up of the eight patients in whon stent placement was successful, restenosisdeveloped in three cases. This occurred during the 7th, 8th, and 15th month, respectively. Two such cases weretreated by balloon dilatation.CONCLUSION:
In hemodialytic shunt-related subclavian vein stenosis, treatmentinvolving the use of a self-expandable metallic stent is useful, especially for treating a lesion which has notresponded to angioplasty with a high patency rate.
