[Atrial fibrillations: daily occurrence possibly leading to embolism in an extremity]. / Boezemfibrilleren: alledaags, maar mogelijk leidend tot embolisatie naar een extremiteit.

A 64-year old woman had been tired and short of breath for the previous few months. During the past few days she had experienced disruptions in the movement and feeling of the right arm and both feet as well as a loss of strength and a heavy feeling in her right leg. Due to atrial fibrillation she had recently started using digoxin and due to possible arterial embolisms in the extremities she had recently started using acenocoumarol. Further investigations revealed one large thrombus in the left atrium, two large thrombi in the left auricle and a serious constriction in the right iliac artery. The thrombi were treated with heparin and oral anticoagulants; the ischaemia which probably occurred as a result of this was successfully treated with embolectomy. After the cardiac thrombi had disappeared, the patient was electrically converted to sinus rhythm. One month later, the patient was still in sinus rhythm and her clinical picture had improved. As she does not feel the atrial fibrillation, she will be permanently maintained on oral anticoagulants. In patients with atrial fibrillations, the possibility of an embolisation towards the extremities deserves serious consideration.
