Value of MR cholangiography in the evaluation of postoperative biliary complications following orthotopic liver transplantation.

摘要: The aim of this study was to describe the spectrum abnormal biliary findings as seen with magnetic resonance cholangiography (MRC) in symptomatic patients after orthotopic liver transplantation (OLT). In our we included 12 consecutive post-OLT who presented clinical and/or biochemical suspicion complications. all MRC performed on a 1.0-T whole-body magnet and breathhold half-Fourier acquired single-shot turbo spin echo rapid acquisition relaxation enhancement sequences were used. Diagnostic confirmation obtained percutaneous transhepatic (PTC; n = 3 patients), endoscopic retrograde (ERC; or follow-up. A vast array abnormalities detected 11 patients: high-grade, obstructive, anastomotic stricture most common unique abnormality. Findings consistent bile duct necrosis, second abnormality, accompanied by arterial 2 5 subsequent MR- digital subtraction angiography. Compared direct (n highly accurate for detection characterization postoperative final diagnosis, which based PTC-ERC available data, imaging alone able provide specific diagnosis 9 patients. Magnetic is an accurate, time-saving, non-invasive modality evaluation whom complications exists. Although precise value MRA patient group requires larger dedicated studies, single session "all-in-one" MR both system series proved be substantial benefit obtaining complete diagnosis.
