Two weeks after TAE, the patient showed abrupt symptoms of duodenal obstruction. Resolving hematomas after successful selective transcatheter arterial embolization should be thoroughly observed because they might result in duodenal fibrotic encasement featuring inflammatory duodenal wall thickening, duodenal deformity, dysmotility, and fi nally obstruction.展开更多
