Embolization of symptomatic renal angiomyolipoma with a mixture of lipiodol and PVA, a mid-term result.

Abstract

OBJECTIVE:

To evaluate the clinical effect of renal artery embolization with a mixture of lipiodol and polyvinyl alcohol (PVA) particles on symptomatic renal angiomyolipoma and to present the mid-term results from our single-center site.

METHODS:

We performed a retrospective review of the seven patients who underwent embolization with a mixture of lipiodol and PVA particles to treat symptomatic renal angiomyolipoma in our center between February 2011 and December 2013. Medical records and follow-up results were reviewed and analyzed.

RESULTS:

Seven patients underwent eight episodes of embolization using a mixture of lipiodol and PVA particles to treat symptomatic renal angiomyolipoma. One patient required a subsequent embolization of the right kidney 9 months after the initial embolization of the left kidney. No nephrectomy was required in any of these cases during follow-up. None had recurrence of tumor bleeding or rupture during follow-up. Decreased tumor size was achieved in six patients (85.7%) during the mid-term follow-up.

CONCLUSIONS:

Embolization with a mixture of lipiodol and PVA particles is an effective and safe treatment for symptomatic renal angiomyolipoma. Based on the durable mid-term results of the present study, a mixture of lipiodol and PVA particles is recommended for embolization.
