A patient with ischemic dilated cardiomyopathy and history of ventricular fibrillation received an implantable cardioverter defibrillator by the nonthoracotomy approach. Four years later, during elective replacement of an exhausted pulse generator, a superior vena caval thrombotic occlusion with collateral circulation through the azygos and emiazygos vein systems was documented. This occlusion occurred despite an anticoagulant treatment in the standard therapeutic range. We speculate that thrombotic occlusion might be secondary to a mechanical vessel injury.
一名患有缺血性扩张型心肌病且有室颤病史的患者通过非开胸手术途径植入了植入式心律转复除颤器。四年后，在择期更换耗尽的脉冲发生器时，记录到上腔静脉血栓形成性闭塞，并通过奇静脉和半奇静脉系统形成侧支循环。尽管抗凝治疗处于标准治疗范围内，但仍发生了这种闭塞。我们推测血栓形成性闭塞可能继发于机械性血管损伤。
