摘要:

目的 机械瓣置换患者妊娠期间抗凝对母体和胎儿具有重要意义.华法林抗凝效果好,血栓栓塞发生率低,但其易致胎儿畸形、流产及死胎.肝素及低分子肝素致畸率低,但血栓栓塞的发生率高于华法林.研究表明日剂量5 mg以下时华法林对胎儿影响较小.对于血栓风险高的患者孕期全程使用华法林是可行的选择,但应慎重评估风险并结合患者本人意愿综合考量.

关键词: 机械瓣, 妊娠, 华法林, 抗凝

Abstract:

Anticoagulation therapy during pregnancy is critical to both mother with prosthetic heart valves and fetus. Warfarin offers the best maternal protection against thrombosis, but it might be associated with a high risk of fetal malformations and pregnancy loss. Heparin derivatives are associated with a reduced risk of fetal damage, but an increased risk of valve thrombosis in the mother. The risk of warfarin-related embryopathy might be dose-related.The use of warfarin throughout pregnancy for those patients at the greatest risk of thromboembolism is feasible.And the patient's preferences should also be take into account.

Key words: prosthetic heart valves, pregnancy, warfarin, anticoagulation
