Percutaneous interventional thrombectomy of an endovascular AV-fistula, a case report.

Dialysis access thrombosis is a common complication in the process of care. With the introduction of endovascular AV-fistulas [AVF]s the situation gained complexity with new potential thrombosis localizations. Several thrombectomy methods are available for recanalization of thrombosed AVFs ranging from invasive surgical methods to minimal invasive endovascular approaches. Early assessment, diagnosis and treatment is crucial for prolonging the life span of an AVF and preventing the need for placement of central venous catheters. To our best knowledge, we present the first case in which an obstructed antecubital communicating vein (aka perforating vein) of an endovascular created AVF was re-opened via interventional thrombectomy with the Rotarex® System (BD Interventional). The procedure was performed primarily under ultrasound guidance with fluoroscopic support. Our case report shows that this method, if done correctly and successfully, may prevent loss of the dialysis access. Additionally, we point towards the central role of ultrasound in this method.
