Acute subdural hematoma (ASDH) occurs after tearing of bridging veins within the dura resulting in the accumulation of blood between the arachnoid and dura layers within 72 hours after traumatic head injury. Also, antigen fibrin D-dimer (DD) is the principal enzymatic degradation product of cross-linked fibrin by plasmin. We observed that early tranexamic acid (TXA) treatment resolved hyper-fibrinolysis and rapid disappearance ASDH. ⋯ Historically, hyper-fibrinolysis is associated with poor outcome in head trauma. However, early initiation of TXA which is noninvasive treatment modality for ASDH could avert surgery and reduce cost, anesthesia, and other complications associated with surgery.

Surgical evacuation is the standard treatment for chronic subdural hematomas (CSDHs) but is associated with a high risk of recurrence and readmission. Middle meningeal artery embolization (MMAE) is a novel treatment approach which could be performed upfront or in adjunction to surgical evacuation. MMAE studies are limited by small sample sizes. This study aimed to describe and compare outcomes of MMAE in adjunction to surgery with those of surgery alone on a national level. ⋯ This analysis of large-scale national data indicates that MMAE performed in adjunction to surgery for treatment of CSDH is associated with higher direct costs, higher complication rates, and longer length of stay but lower readmission rates compared with surgical evacuation alone.

Some patients with subdural hematoma (SDH) with acute extra-arachnoid lesions and without concomitant subarachnoid blood or contusions may present in similarly grave neurological condition compared with the general population of patients with SDH. However, these patients often make an impressive neurological recovery. This study compared neurological outcomes in patients with extra-arachnoid SDH with all other SDH patients. ⋯ Patients with extra-arachnoid SDH have significantly better 2-week neurological outcomes and lower mortality than predicted by the Corticosteroid Randomization After Significant Head Injury model. Neurosurgeons should consider surgery for this patient subset even in cases of poor neurological examination, older age, and large hematoma with high degree of midline shift.

Although tranexamic acid (TXA) has occasionally been used to prevent postoperative recurrence of chronic subdural hematoma (CSDH) after burr hole craniotomy (BC), robust evidence of its efficacy has been lacking. ⋯ Oral administration of TXA reduced the occurrence of repeat surgery after BC for CSDH.

We sought to describe the resolution time of chronic subdural hematoma (CSDH) after middle meningeal artery embolization (MMAE) and potential variables that may affect hematoma resolution. ⋯ MMAE is an effective and minimally invasive treatment for CSDH with a lower recurrence rate. The median resolution time of CSDH following MMAE was 19 weeks (interquartile range: 8-24). Burr-hole irrigation contributed to early hematoma resolution but had no significant effect at 6 months. In addition, residual hematoma thickness, postoperative midline shift, and specific type of hematoma were associated with delayed hematoma resolution at 4 months.
