  • Title: [Neurological complications after open heart surgery. Risk factors identified in a retrospective study].
    Author: Steuer J, Ivert T.
    Journal: Lakartidningen; 1998 Sep 30; 95(40):4348-53. PubMed ID: 9800454.
    Abstract:
    Cerebral complications were documented in 2 per cent (133/6666) of open heart procedures performed in adults at the Karolinska hospital, during the 7-year period, 1990-96. In 32 per cent (42/133) of cases, the neurological symptoms appeared after an uneventful postoperative interval of 2-14 (median 3) days. These patients were older and were characterised by a tendency toward a greater prevalence of carotid artery disease and of postoperative atrial arrhythmia. By contrast, the subgroup whose cerebral symptoms occurred immediately after the operation was characterised by greater severity of the symptoms, long operation time, and poor preoperative left ventricular function. Aggressive postoperative anticoagulant treatment, especially in patients with supraventricular arrhythmias, would seem to be justified to reduce the risk of neurological complications.
