Efficacy analysis of flexible neuroendoscopy combined with dry-field techniques in the treatment of chronic subdural hematoma

Abstract

[2] With improvements in medical imaging technology and related basic research, the perception of CSDH as an inflammatory vascular proliferative disease has gradually reached consensus. [3] In addition to head trauma, brain atrophy leading to expanded subdural space is the premise and primary reason for the occurrence of CSDH in the older adult population. The study was conducted by the Declaration of Helsinki and was approved by the Institutional Review Board of Capital Medical University. Inclusion criteria were as follows: (1) medical history of head trauma or no clear medical history; (2) symptoms such as headache, vomiting, blurred vision, seizures, memory and mental retardation, or mental disorders; (3) neurologic dysfunction, such as hemiplegia or aphasia; (4) CT showed crescent, half-moon, or fusiform low density appearing mainly below the inner plate cranial bone, possibly accompanied by brain deformation and midline shift; (5) no medication history for CSDH; (6) suspension of anticoagulant drugs such as aspirin for more than 10 days; and (7) non-recurrent CSDH.
