RESEARCH CT SCAN IMAGINGS AND SOME CLINICAL CHARACTERISTICS OF CHRONIC SUBDURAL HEMATOMA IN CLINICALLY UNDIAGNOSED PATIENTS

Purpose: The goal of study was to investigate and compare clinical characteristics, surgical characteristics and CT scan characteristics of chronic subdural hematoma in patients undiagnosed clinically. Material and method: a cross-sectional study was conducted in a sample of 64 patients having non apparent clinical symptoms, with chronic subdural hematoma images, being treated surgically from 5/2010 to 7/2011in Hue central hospital. Result: Mean age is 60.45. Proportion male to female is 11.8/1. Traumatic history accounts for 65.6%. Hematoma in frontal- temporal- parietal regions accounts for 50%. Minimum midline displacement is 1mm; maximum midline displacement is 26mm. Minimum hematoma width is 1 mm; maximum hematoma width is 34 mm. Hypodensity of hematoma accounts for 67.2%. Conclusion: Headache and traumatic history are two major clinical characteristics of chronic sudural hematoma. Characteristics of chronic sudural hematoma is hypodensity, homogeneous. There is a relationship between CT scan characteristics, clinical characteristics and surgical characteristics in CSH.
