Acute renal failure followed by percutaneous mechanical thrombectomy with AngioJet

Percutaneous mechanical thrombectomy (PMT) is a well-established technique for treatment of acute arterial and venous thrombosis. AngioJet (Boston Scientific, Inc., Natick, MA, USA) is a unique system that uses high-velocity saline jets to fragment and aspirate thrombus with the Venturi-Bernoulli effect. This inevitably leads to intravascular erythrocyte hemolysis, resulting in hemoglobinuria. Cell-free hemoglobin can cause renal tubular damage by complex intrarenal oxidative reactions which trigger a heme toxicity response. Only several cases of acute kidney injury following AngioJet PMT have been published in literature. To our knowledge, this is the first reported case of dialysis-requiring AKI after PMT for peripheral arterial thrombosis.
