BACKGROUND
For patients who undergo mechanical valve replacement, the greatest disadvantage is that they require long-term or permanent use of anticoagulant therapy to prevent thromboembolism. To date, mechanical valve replacement without anticoagulation has been published in the literature.
CASE SUMMARY
We present the case of a 75-year-old female who underwent mechanical mitral valve replacement (MVR) on midJune, 2007. However, this patient had not been taking anticoagulant medication since she experienced warfarin overdose in the first month after the operation. She had been well without using any anticoagulation, and there were no complications of the mechanical valve.
DISCUSSION
There was no thrombosis for such a long period of time because she suffered from FX deficiency. To the best of our knowledge, she may be the only patient who has been well without any anticoagulation since not taking warfarin 12 years ago.
背景
对于接受机械瓣膜置换术的患者而言，最大的不利之处在于他们需要长期或终身使用抗凝治疗以预防血栓栓塞。迄今为止，文献中已报道了无需抗凝的机械瓣膜置换术案例。
病例摘要
我们呈现一名75岁女性的病例，该患者于2007年6月中旬接受了二尖瓣机械瓣膜置换术（MVR）。然而，该患者自术后第一个月华法林过量以来就未服用抗凝药物。她未使用任何抗凝药物却状况良好，且机械瓣膜未出现任何并发症。
讨论
由于她患有因子X缺乏症，所以在如此长的时间内未发生血栓形成。据我们所知，自12年前停用华法林以来，她可能是唯一未进行任何抗凝治疗却状况良好的患者。
