Rheolytic Thrombectomy with AngioJet®Is Safe and Effective in Revascularization of Renal Arteries' Acute Occlusion on Previous Complex Aortic Endovascular Repair

Acute occlusion of the visceral arteries is a threatening complication following branched endovascular aortic repair (EVAR). Its prompt diagnosis and treatment are mandatory to restore renal function. Several techniques have been used to manage this complication. We report 2 clinical cases of patients, previously treated with implantation of an off-the-shelf thoracoabdominal aortic endograft, with acute bilateral occlusion of the renal arteries. Both patients were successfully treated with AngioJet rheolytic thrombectomy. Acute occlusion of the renal arteries can dramatically complicate the outcome of patients treated with branched EVAR. Prompt diagnosis and treatment are required. Rheolytic thrombectomy rapidly removes intra-arterial thrombus through Bernoulli effect, preventing the risk of distal embolization and rapidly restoring the renal function.
