Expanded Polytetrafluoroethylene-covered Stent Treatment of Angioplasty-related Extravasation during Hemodialysis Access Intervention: Technical and 180-day Patency

In 21 patients, the ePTFE-covered stent successfully treated PTA-induced rupture with no need for acute secondary procedures such as thrombolysis or surgery. There was no instance of pseudoaneurysm formation or delayed bleeding. The ePTFE-covered stent offers advantages compared to prolonged PTA or bare stents when attempting to preserve hemodialysis access after PTA-induced rupture.
