Abstract
By the use of 125I-labeled fibrinogen test, the incidence of postoperative deep vein thrombosis (DVT) and the effectiveness of prophylactic low-dose heparin treatment were investigated in 110 patients who underwent elective neurosurgical procedures. Fifty patients were appointed randomly to a control group and 50 to a heparin group (10 patients were excluded since they had DVT before surgery). The incidence of DVT was reduced from 34% in the control group to 6% in the heparin group (p less than 0.005). No statistically significant differences were observed in transfusion requirements, postoperative hemoglobin concentration, and the occurrence of postoperative hematomas between the two groups. Positive correlation was observed between DVT and motor deficit (p less than 0.05). Preoperative assessment of patients' sensitivity to the standard 5000-unit dose of heparin was performed in all treated patients and is thought an important factor in improving the safety of heparin prophylaxis.Keywords
