Comparing Patency Rates of Arteriovenous Dialysis Access following Percutaneous Thrombectomy Using Various Catheter Directed Therapies.

Background: Arteriovenous fistulas often require frequent interventions to maintain patency for hemodialysis. Interventions may include open or percutaneous thrombectomy with additional targeted interventions as indicated. We evaluated the primary and cumulative functional patency rates following three unique approaches to percutaneous thrombectomy of thrombosed dialysis access.

Endovascular Repair of Transected Axillary Artery via Snare Assisted Through and Through Femoral to Brachial Artery Access.

Axillary artery injury is a rare but complex surgical problem that often requires challenging exposures, lengthy operations, and morbid outcomes for repair. For these reasons, endovascular repair is an attractive alternative as it obviates many of the challenges present with open repair. While pseudoaneurysms, dissections, and short segment injuries with limited arterial disruption are regularly treated endovascularly, complete arterial transections are almost exclusively treated with open repair as obtaining wire access across the site of injury is often not possible.

Endovascular Treatment of Innominate Artery Bifurcation Injury with Balloon-Expandable Covered Stents Utilizing Kissing Stent Technique.

Major injury of the innominate artery is traditionally treated with an open repair which is technically challenging, associated with large volumes of blood loss and prolonged operative times. Endovascular treatment with covered stent placement across the injury is an attractive alternative. However, placement of a single covered stent across the innominate artery bifurcation into one of its distal branches will not prevent bleeding because of retrograde perfusion from the unstented branch distal to the bifurcation.
