We present four cases of late thrombotic obstruction of the Björk-Shiley aortic valve prosthesis. The incidence of this complication reported in the literature to vary from 0.7% to 5%. In our experience of a total of 623 Björk-Shiley aortic valve replacements, we observed this complication in only 4 patients (0.6%). Two of them had poorly controlled anticoagulation therapy. The clinical presentation was subacute in all four patients. Surgical treatment, thrombectomy and debridement, was performed in all of them. The diagnosis was made upon abrupt and progressive onset of dyspnoea, physical examination data and echocardiographic and radioscopic findings. Angiocardiographic studies were needed in two patients.
我们报告了4例Björk-Shiley主动脉瓣假体晚期血栓阻塞的病例。文献报道该并发症的发生率在0.7%至5%之间。在我们总共623例Björk-Shiley主动脉瓣置换术的经验中，仅4例患者（0.6%）出现了这种并发症。其中2例患者的抗凝治疗控制不佳。所有4例患者的临床表现均为亚急性。所有患者均接受了手术治疗，即血栓切除术和清创术。根据呼吸困难的突然和进行性发作、体格检查数据以及超声心动图和放射学检查结果做出诊断。2例患者需要进行心血管造影研究。
