How safe is embolization for angiomyolipoma on kidney?

How safe is embolization for angiomyolipoma on kidney?

Depends on reason: Embolization is indicated for renal angiomyolipomas in the setting of bleeding from the tumors. In such cases, the procedure can be life-saving and can also help preserve kidney tissue (as opposed to taking the whole organ out). In skilled hands, it is considered to be relatively safe and necessary procedure. As with all vascular procedures, the major risk is bleeding from the site. ...Read more

It carries a risk of bleeding. Embolization or placing coils into the small arteries feeding the mass is one way to treat it. The decision may require careful evaluation of the size and location of the mass. ...Read more
