Subdural Tension on the Brain in Patients with Chronic Subdural Hematoma Is Related to Hemiparesis but Not to Headache or Recurrence

摘要: Background Hemiparesis is a major symptom of chronic subdural hematoma (CSDH). Its severity does not always correlate with size. The authors analyzed thickness, pressure, and tension to clarify the mechanism hemiparesis in CSDH patients. Methods A burr-hole surgery was performed on 124 CSDHs 102 Hematoma thickness midline shift were measured by computed tomography, pressure surgery. According Laplace law, calculated as follows: (half thickness × pressure)/2. Student t test Pearson correlation coefficient (r) applied statistical analysis findings. Results Motor weakness identified 76.5% our cases. Tension strongly related (r = −0.747, P Conclusions most influencing factor This study also elucidates for quick recovery from after that motor cortex decreased immediately drainage.
