Percutaneous thrombectomy with the JETi6 device for the treatment of acute renal artery thrombosis with renal failure

Abstract

Introduction: Renal artery thrombosis (RAT) is a rare disease which causes decreased renal blood flow and can result in permanent renal damage and subsequent arterial hypertension. Cardiac embolization is the most frequent cause, however in situ thrombosis of an underlying atherosclerotic stenosis is not uncommon. Methods: Acute renal failure was seen in a 79-year-old woman following acute thrombosis of the renal artery. Percutaneous renal thrombectomy with the JETi6 device was performed as well as complementary stenting for an underlying atherosclerotic stenosis. Results: Rapid flow restoration was achieved and normalization of renal function and blood pressure were seen. Follow-up at 1 month showed no complications. Conclusion: Guidelines for the management of renal artery thrombosis are lacking. Compared to thrombolysis, percutaneous thrombectomy allows rapid flow restoration, with better preservation of renal function, and fewer hemorrhagic complications. Additional angioplasty when underlying stenosis is present allows longer vessel patency. This is a unique report highlighting the efficacy and safety of the JETi6 thrombectomy device in the treatment of an acute in situ renal artery thrombosis.
