In unresectable metastatic liver lesions positive for somatostatin receptors repeated, transhepatic high doses of (111)In-DTPA-Phe(1)-octreotide show an effective therapeutic outcome. Given the locoregional modality character of the administration technique plus the extremely short range of (111)In Auger and internal conversion electrons emission, no nephro-, liver- or myelo-toxicity has so far been observed.
Superselective embolization resulted in permanent cessation of bleeding. Serious parenchymal infarction was prevented and serum creatinine level returned to the pre-bleeding values. Embolization should be considered as the treatment of choice in this patient population.
We report a case of a 33-year-old woman with tuberous sclerosis and bilateral angiomyolipomas. She suffered from acute left flank pain due to retroperitoneal haemorrhage. During renal arteriography an arteriovenous shunting was found in the left tumour. Angiomyolipoma is a rare cause of angiographically demonstrable arteriovenous shunting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
