Symptomatic hepatic hemangiomas are commonly treated by transcatheter arterial embolization as an alternative to surgical resection. Bile duct complications are rare. An 80-year-old woman had a progressive refractory stricture postbleomycin transcatheter arterial chemoembolization. Magnetic resonance cholangiopancreatography showed that the hemangioma reduced in size, but there was a new 2 cm hilar stricture on cholangiopancreatography. Digital cholangioscopy and biopsy showed benign changes. Despite repeat dilations and stent treatments, she had persistent stricture and recurrent cholangitis. The stricture was not operable. The stricture was likely from angiosclerotic effects of bleomycin. The bile duct is prone to ischemic injury as it lacks dual blood supply.
有症状的肝血管瘤通常采用经导管动脉栓塞术治疗,作为手术切除的替代方法。胆管并发症很少见。一名80岁女性在博来霉素经导管动脉化疗栓塞术后出现进行性难治性狭窄。磁共振胰胆管造影显示血管瘤缩小,但胰胆管造影显示有一个新的2厘米肝门部狭窄。电子胆管镜检查和活检显示为良性改变。尽管反复进行扩张和支架治疗,她仍有持续性狭窄和复发性胆管炎。该狭窄无法手术治疗。该狭窄可能是博来霉素的血管硬化作用所致。胆管由于缺乏双重血液供应,容易发生缺血性损伤。
