[Endovascular treatment of traumatic and iatrogenic intrarenal arterial lesions by microcoil embolization].
Selective embolization is the best treatment for intrarenal arterial lesions due to trauma or percutaneous procedures with non-controlled or recurrent haematuria. Three male patients, aged 20-70 (mean 49 years), were recently treated in our institution by means of arterial embolization with microcoils. Two patients presented a pseudo-aneurysm and an arterio-venous fistula secondary to percutaneous nephrolithotomy and one patient presented an isolated pseudo-aneurysm due to trauma. In the 3 cases, haematuria (associated with retroperitoneal haemhorrage in one case) was not controlled and required repeated units of blood. Embolization allowed definitive treatment of these lesions. One of our patients with a solitary functional kidney presented rapidly increasing renal failure which completely resolved after arterial embolization. We think that microcoils are the embolic agents of choice to perform endovascular treatment in this indication.
