Abstract:
A 60-year-old patient, known for cirrhosis of alcoholic origin with several hemorrhagic risk factors, is hospitalized for stone cholangitis. He benefits from endoscopic retrograde cholangiopancreatography which is complicated by several upper digestive hemorrhages due to bleeding from the duodenal papilla. The hospital stay is compounded by bacteremia, suspicious for endocarditis, prompting the performance of a PET-CT. Just after this medical examination, the patient again presents with rectal bleeding. In certain 18F-FDG PET-CT preparation protocols, the administration of heparin is carried out in order to improve the quality of the images.
