title: Transradial embolization of a bleeding renal angiomyolipoma.
abstract: Renal angiomyolipoma (AML) is a benign neoplasm with a propensity to bleed among patients with tumors exceeding 4 cm in diameter but can be effectively treated with transarterial embolization to arrest or prevent hemorrhage. We report the use of transradial approach to embolize a bleeding AML in a pregnant patient in order to minimize pelvic radiation. This case illustrates the utility of transradial access as an access approach for performing superselective visceral embolization when a femoral approach is undesirable or not possible.
