Acute Distress Respiratory Syndrome and Cardiac Shock after AngioJet Thrombectomy for Acute Occlusion of an Aortic Endograft.

Partial thrombosis or total occlusion of aortic or limb graft are possible complications after endovascular aneurysm repair. Different strategies for therapeutic management are available; these include open surgical techniques or endovascular treatments. The choice of the treatment depends on the patient's clinical conditions and on the timing of the thrombosis. Bypass still remains the first choice in case of chronic occlusion but in the last 10 years, the use of percutaneous mechanical/rheolytic thrombectomy systems is increasing. These devices can be used in case of acute or subacute onset of native arterial and venous thrombosis or embolism and in case of graft occlusion. AngioJet is a percutaneous rheolytic mechanical thrombectomy system. Through a pressurized saline solution jet, a low-pressure zone is made up and the thrombus is fragmented and aspirated by the device. Different transient adverse effects caused by lysis of the thrombus are described such as hemoglobinuria but in some cases the release of high doses of the thrombus degradation products such as heme and adenosine diphosphate can lead to fatal consequences for the patient. We reported a case of an acute onset of acute distress respiratory syndrome, pulmonary edema, cardiac shock, and renal failure following AngioJet thrombectomy in an 81-year-old man with an acute occlusion of an aortic endograft.
