Transjugular intrahepatic portosystemic shunt: evaluation with Doppler sonography.

abstract：:Tumors of the skull base frequently have some blood supply from cavernous branches of the internal carotid artery (ICA). Preoperative embolization of such pedicles can expedite the subsequently performed surgery. Sometimes, however, the tumor vessels are multiple and very small so selective catheterizations are not po...
