Revascularization of traumatic renal artery dissection by endoluminal stenting: three cases.

Traumatic injury of renal arteries is rare and can induce renal dysfunction and hypertension. Management options include observation, nephrectomy, surgical repair, and, more recently, percutaneous angioplasty. We report three cases of renal artery thrombosis occurring in young multitrauma patients (mean age 28.7 years) treated with stenting. Immediate satisfactory results were obtained in all cases. Postprocedure anticoagulant and antiplatelet treatment were given according to associated contraindicating lesions. During follow-up, in-stent restenosis occurred in one patient and was treated successfully with a second stenting procedure. No renal dysfunction or hypertension was observed after 28.6 months follow-up. Percutaneous angioplasty is a valuable alternative to surgical treatment in selected patients.
