Superselective endo-vascular treatment of renal vascular lesions.
Embolization with platinum micro-coils delivered through the Tracker-18 micro-catheter was performed in 6 patients when peripheral selective catheterization with standard angiographic catheters was not possible. The patients had a total of 7 peripheral renal vascular lesions (3 arteriovenous fistulas, 2 false aneurysms, 1 direct vascular trauma and 1 arteriovenous malformation). In all patients we initially used platinum micro-coils as the embolic agent. Two patients required repeat embolization with glue. Endo-vascular treatment was technically successful in all cases and no complications were encountered. There was no renal parenchyma infarction in 3 patients and small peripheral infarctions (10 to 15% of the renal parenchyma) occurred in 3. Super selective endo-vascular treatment with a variable stiffness catheter is safe and useful technique when classical methods of embolization are not possible.
