生物瓣膜与机械瓣膜有什么区别 怎样选择 黄继江 徐州矿务集团总医院 机械瓣是由于钛合金做成，寿命可以在五六十年，缺点是终生抗凝，每天都不能少，而且需要定期检测，根据情况调整用药。生物瓣寿命短，工序就多复杂，影响因素比较多，质量就不好控制，寿命长短不同。在置换过程中，要求严格，好的可以用20多年，也有2-3个月就坏的，一般来说寿命在15年左右。血流动力学方面生物瓣膜很有优势，在仿生性很好。生物瓣优点是对抗凝要求不高，可以不吃药。生物瓣膜与机械瓣膜的选择：小孩子（10岁以下）代谢旺盛，血液中钙磷含量高，容易在瓣膜周围沉积，所以这类患者也是以选用机械瓣优先，其他患者都以用生物瓣膜优先。如70岁以上身体健康，可以独立生活的老人、年轻女性病人、预期寿命在15年之上的、肿瘤患者、特殊生活方式的病人，或者是杂技演员、特技演员等都可以用生物瓣膜。 What is the difference between biological valve and mechanical valve? How to choose The mechanical flap is made of titanium alloy, The life span can be fifty or sixty years, The disadvantage is lifetime anticoagulation, Every day, And it needs to be tested regularly, Adjust medication according to the situation. The life span of biological valve is short, The process is more complicated, There are many influencing factors, Quality is not easy to control, Life span is different. In the process of replacement, Strict requirements, It can be used for more than 20 years, It's also broken in 2-3 months, Generally speaking, the life span is about 15 years. Biological valves have advantages in hemodynamics, Good in bionics. The advantage of bioprosthetic valve is that the anticoagulation requirement is not high, No medicine. Selection of biological valve and mechanical valve: young children (under 10 years old) are metabolized vigorously, The content of calcium and phosphorus in blood is high, It is easy to deposit around the valve, So this kind of patients also choose mechanical valve first, Biological valve is preferred in other patients. If you are over 70 years old and healthy, The elderly, young female patients who can live independently, patients with life expectancy over 15 years, cancer patients, patients with special lifestyle, Or acrobats and stuntmen can use biological valves.
