¶Background. Despite the high risk of venous thromboembolic events (VTE) in neuro-surgical patients, heparin prophylaxis has not been routinely established due to concern about bleeding complications. After initiating early low molecular weight heparin (LMWH) prophylaxis, we reviewed our patients in order to examine the viability of this practice.
Method. Over a 3 year period, the records of patients admitted for elective neuro-surgery (ES), head injury (HI) or spontaneous intracranial haemorrhage (ICH) were analysed. Prophylaxis was performed with certoparin (3000 U anti-factor Xa s.c.) on the evening before ES and within 24 hours after surgery or admission whenever a CT did not show a progress-sive haematoma. Contraindications for LMWH were prothrombin time <70%, partial thrombo-plastin time >40 s, platelet count <100.000/ml, and platelet aggregation test sum <60%. The incidence of bleeding complications, VTE, and resulting morbidity/mortality was assessed.
Findings. 294 patients were admitted for ES, 344 for HI, and 302 for ICH. 155 of these were excluded because of contraindications. Intracranial bleeding was recorded in 1.5% (ES 1.1%, HI 3.5%, ICH 0%) and operative revision was performed in 1.1% (ES 0.7%, HI 2.8%) of patients. One case of moderate disability and no mortality occurred. The incidence of VTE and pulmonary embolism was documented in 0.2% and 0.1% of patients, with no associated mortality. No heparin induced thrombocytopenia was observed.
Interpretation. In neurosurgical patients, antithrombotic prophylaxis with certoparin was determined to be safe and efficacious when contraindications are carefully considered and a 12-hour time interval before and after surgery was guaranteed. This retrospective analysis should encourage a prospective trial of early LMWH prophylaxis.
