- W2005717177 abstract "1 Introduction: Cerebral haemorrhage could complicate post operative course after cardiac surgery, especially after multiple mechanical valves replacement needing for anticoagulation. The interruption of vitamin K antagonists in this cases, to avoid the enhancement of the cerebral haemorrhage, can be performed with reasonable safety. Case Presentation: We report the case of a patient who underwent mitro-aortic valve replacement with mechanical valves. Postoperative course was uneventful until the 6th day when he developed paresthesias on the left side and left arm paresis; CT scan showed a sub-cortical cerebral haemorrhage. in the right temporo-parietal area. At that time, he was receiving Enoxaparin (4000 IU/day) and Acenocoumarol (1 mg/day) which were started on the 2nd postoperative day without a loading dose. The patient was then transferred to another hospital where neurosurgery intensive care unit was available; he was conservatively treated without surgery. During his stay at this hospital he did not receive vitamin K antagonists until February, 7th for a total of 117 days receiving only 4000 IU Enoxaparin daily. He was then re- evaluated at our hospital on April 2nd 2008 with transthoracic echocardiography and fluoroscopy: both valves were well functioning with no major problems. Discussion: Withholding anticoagulant therapy after mechanical heart valve replacement due to the severe haemorrhage is a complex problem that can occur after heart valve surgery. Although it has been shown that interruption of vitamin K antagonists can be performed in patients with mechanical valves with reasonable safety for a short-term period. As the patient transferred to another hospital after the occurrence of cerebral haemorrhage, he was treated only with low doses of enoxaparin for 117 days. In less than two months after the coumarols resumption, the subsequent reassessment of the valves performed using echocardiography and fluoroscopy confirmed the normal performance of both mitral and aortic valves. In this case, a very long suspension of standard anticoagulant therapy did not affect the performance of mechanical bi-leaflet mitral-aortic prostheses." @default.
