Elderly patients often suffer from cardiovascular diseases and are treated with anticoagulation medications, which must be taken into consideration when planning elective surgery.
The etiology, diagnostic work-up and clinical management of selected inherited and acquired hemophilic and thrombophilic coagulation disorders are described.
Data from clinical studies, current guidelines and expert opinions are discussed.
Beside inherited hemophilic coagulation defects, elderly patients very frequently show an acquired bleeding tendency caused by the intake of analgesic drugs or long-term medication due to cardiovascular diseases. In rare cases, elderly patients can develop acquired hemophilia caused by autoantibodies to coagulation factors resulting in a severe bleeding disorder. Moreover, elderly patients have an increased risk to develop venous or arterial thrombotic events. Prior to surgery a relevant bleeding tendency should be excluded by the combination of medical history, clinical investigation and screening of laboratory parameters. If laboratory parameters are outside the normal range, e.g. a prolonged activated partial thromboplastin time (aPTT), the reasons must be clarified prior to an elective surgery.
The clinical management of elderly patients under anticoagulation treatment should start early and must also cover the post-surgery period. When planning treatment for patients at risk, a physician qualified in clinical hemostaseology should be consulted. For the management of thrombosis prophylaxis, the implementation of clinical guidelines is a valuable measure.
老年患者常患有心血管疾病并接受抗凝药物治疗,在计划择期手术时必须考虑这些因素。
描述特定遗传性和获得性血友病及血栓形成倾向凝血障碍的病因、诊断检查和临床管理。
讨论来自临床研究、现行指南和专家意见的数据。
除遗传性血友病性凝血缺陷外,老年患者常因服用镇痛药或因心血管疾病长期用药而出现获得性出血倾向。在罕见情况下,老年患者可因针对凝血因子的自身抗体而发生获得性血友病,导致严重出血性疾病。此外,老年患者发生静脉或动脉血栓事件的风险增加。在手术前,应通过病史、临床检查和实验室参数筛查相结合来排除相关出血倾向。如果实验室参数超出正常范围,例如活化部分凝血活酶时间(aPTT)延长,在择期手术前必须查明原因。
接受抗凝治疗的老年患者的临床管理应尽早开始,并且还必须涵盖术后阶段。在为有风险的患者制定治疗计划时,应咨询具有临床止血学资质的医生。对于血栓形成预防的管理,实施临床指南是一项有价值的措施。
