Prophylaxis against thromboembolism in patients with traumatic brain injury: a survey of UK practice.

Venous thromboembolism is a major complication associated with traumatic brain injury and is responsible for significant morbidity and mortality. There has been a general reluctance over the years to use anticoagulant prophylaxis for patients with head injury who have suffered intracranial bleeding or for whom intracranial surgery is needed. We conducted a postal questionnaire survey of all neurosurgical centres in the United Kingdom, enquiring about the use of thromboprophylactic methods in the management of patients with traumatic brain injury. A diversity of practice and opinion in the use of such methods was evident from the replies received. The survey highlighted concern about the failure to implement even the most simple means of prophylaxis. The evidence for the use of the various methods of prophylaxis is reviewed.
