The influence of preoperative anticoagulation on outcome and quality of life after surgical treatment of chronic subdural hematoma.
The main aim of this study was to investigate the influence of perioperative anticoagulation on the clinical course and outcome of 144 patients who underwent surgery for chronic subdural hematoma (CSDH). The outcome was categorized according to the modified Rankin Scale (mRS), Barthel Index and postoperative quality of life (QoL) scale. There was a significant correlation between preoperative aspirin medication and reoperation (Mann-Whitney U-test, p<0.05). Moreover, dosage and duration of postoperative low-molecular-weight heparin (LMWH) administration were associated with a higher risk of reoperation (Mann-Whitney U-test, p<0.01) and a worse outcome on the mRS (Mann-Whitney U-test, p<0.05). Intraoperative treatment with prothrombin complex concentrate led to a poor outcome on the mRS (Craddock-Flood test, p<0.05). Reoperation is the strongest predictive factor of a poor QoL after surgical treatment of CSDH. Both preoperative and postoperative anticoagulation treatment may affect reoperation rate and, thus, postoperative QoL.
