Long-term results of the transcatheter arterial embolization for ruptured renal angiomyolipoma

Purpose : The long-term results were studied in patients who underwent transcatheter arterial embolization (TAE) for the spontaneous rupture of renal angiomyolipoma (AML).Materal and Methods : Five cases (1 male, 4 females) who underwent TAE for spontaneous AML rupture between November 1996 and February 2000 were studied. Spontaneous rupture of AML was diagnosed with CT.Result : In 4 cases, after performing TAE only one time, the tumor size was reduced and there has been no re-rupture or re-bleeding during the ongoing follow-up. In the other case, an enucleation operation was carried out 11 days after TAE in accordance with the patient's request.Discussion : Recently, there have been a few reports on the long-term effectiveness of TAE, a conservative treatment for renal AML rupture. Our study indicated that TAE might be recommended for patients with renal AML rupture not only for stanching and pre-operative treatment but also for a conservative treatment with regular follow-up.
