Renal arteriovenous malformations (AVMs) are abnormal communications between the intrarenal arterial and venous systems. These malformations are either congenital, acquired (often by iatrogenic means) or idiopathic, and are usually diagnosed while revealing the source of macrohematuria (Multislice spiral CT or angiography). Endovascular method - super selective embolization (SSE) was widely implemented (as monotherapy) in diagnostics and treatment of congenital renal arteriovenous malformations that are clinically apparent during the last decade. This method is considered to be an alternative to an open surgery (kidney resection or nephroectomy).
We posses an experience of successful use of SSE to treat hematuria caused by congenital AVMs in three patients. In all observations we managed to gain a good clinical effect without performing an open surgery. The complications during the embolization and post-embolization period were not observed.
Thus, the SSE is an effective and less invasive method of endovascular diagnostics and liquidation of hemorrhage, caused by congenital renal AVM.
