AbstractIt is written to discuss the effect and syndromes of novel YL-1 hollow needle aspiration drainage system to treat chronic subdural hematoma. Collecting clinical data about 697 patients with chronic subdural hematoma in neurosurgery of People' Hospital in North Jiangsu from January 2004 to December 2014, including clinical manifestation, imaging data, operation time, postoperative complications and prognostic factors and so on. 593 patients got cured, 53 patients with recurrence, 19 patients with acute subdural hematoma, 13 patients with poor drainage, 9 case of patients with acute epidural hematoma, puncture failure in 6 cases, 3 cases of pulmonary infection, one got intracranial hemorrhage (brain stem and basal ganglia hemorrhage). The total time of the operation is 15-28 min, the mean time is 18 ± 3.6 min, the average retention time of novel YL-1 hollow needle aspiration drainage system was 2.6 ± 1.3 days, the average use of urokinase was 30,000 ± 2.10,000 units. It takes a short time for novel YL-1 hollow needle aspiration drainage system to treat chronic subdural hematoma without any syndromes like brain tissue injury, tension pneumocrania, intracranial infection and so on. The clinical cure rate is 85.08 %, recurrence rate is 7.6 %. Using novel YL-1 hollow needle aspiration drainage system to treat chronic subdural hematoma is such a minimally invasive surgical technology which has a higher curative rate, small damage, is also easy to operate with security and less severe complications.
