The bleeding occurs within the layers of tissue that surround the brain. It collects under the brain’s toughWhat causes SDH to appear without trauma?
While rare, SDH’s can also appear without trauma. Abnormal blood vessels, dehydration, cancer, and blood clotting disorders have caused spontaneous SDH’s. Blood clotting medications, anabolic steroids used in body building, or cocaine use might also be factors. What are the different types of SDH?Does preoperative neurologic status predict outcome after drainage of chronic SDH?
Outcome after drainage of a chronic SDH has also been found to correlate with preoperative neurologic status. Early diagnosis before a significant neurologic deterioration may correlate with a more favorable prognosis. No correlation has been found between preoperative CT findings and postoperative outcome.What are the mortality and morbidity associated with sdsdhs?
SDHs can be associated with high mortality and morbidity, even when the best medical and neurosurgical care is provided. They are usually caused by trauma but can be spontaneous or result from a procedure (eg, lumbar puncture). [ 1] Anticoagulation (eg, with heparin or warfarin) may be a contributing factor.
