ReviewRecent Advances and Future Directions in Middle Meningeal Artery Embolization for Chronic Subdural Hematomas.
The purpose of this review is to present a brief background on chronic subdural hematomas (cSDH), middle meningeal artery (MMA) embolization, and its role in decreasing recurrence of cSDH. A review of the most up-to-date literature should demonstrate the efficacy of this procedure. ⋯ The latest data shows that MMA embolization is a safe procedure, with low complication rates and low recurrence rates. While cSDH managed with surgical evacuation can have a recurrence rate upwards of 30%, MMA embolization alone or as an adjunct to surgery decreases recurrence to less than 5% in most studies. MMA embolization can be especially useful in high-risk populations such as the elderly, patients on anti-platelet medication, and those with coagulopathies. It can also be done awake, done without general anesthesia, and is significantly less invasive than traditional surgical techniques. In reviewing the literature on MMA embolization, it is clear that there are numerous retrospective studies and systematic reviews demonstrating its safety and efficacy, and some prospective dual-arm studies that present novel information. The numerous clinical trials that are currently underway should help to further establish MMA embolization as standard of care in the management of cSDH.

Observational Study
Nationwide Readmission Rates and Hospital Charges for Patients With Surgical Evacuation of Nontraumatic Subdural Hematomas: Part 1-Craniotomy.
Despite patients experiencing high recurrence and readmission rates after surgical management of nontraumatic subdural hematomas (SDHs), few studies have examined the causes and predictors of unplanned readmissions in this population on a national scale. ⋯ National trends in 30-day readmission rates after nontraumatic SDH treatment by craniotomy provide quality benchmarks that can be used to drive quality improvement efforts on a national level.

Spontaneous acute subdural hematoma (sASDH) is a rare neurosurgical condition, with the literature mainly consisting of case reports. In the present study, we compared sASDH with traumatic ASDH (tASDH) to determine the differences in presentation, radiological features, and outcomes in a population-based setting. ⋯ In the present population-based study of surgically evacuated ASDH cases, 9% were spontaneous without previous trauma. The outcomes (GOS scores) were significantly more favorable for those with sASDH than for those with tASDH. In one half of the patients with sASDH, arterial bleeding was noted perioperatively, although the preoperative radiological examinations revealed no abnormalities for most patients. However, the lack of sufficient examinations such as computed tomography angiography made it difficult to establish the most common etiology of bleeding in those with sASDH. Further research is warranted to determine the reference standard method for the investigation of sASDH.

The transradial approach has increasingly been used for neurointerventions because of the improved safety profile compared with transfemoral. However, it is important to be aware of potential complications such as radial artery (RA) spasm, RA occlusion, pseudoaneurysm, extravasation, arteriovenous fistula, and wrist hematoma as well as their management. ⋯ Transradial access for neurointervention has a low rate of local complications, particularly when taking appropriate prevention measures. Appropriate management of complications can prevent procedural failure and has low morbidity rates demonstrating the overall safety profile of transradial access even when complications occur.

Middle meningeal artery embolization (MMAE) is an effective minimally invasive treatment for chronic subdural hematomas (cSDHs). The authors investigated outcomes of primary, adjunct, and rescue MMAE and primary surgery for the treatment of cSDH using a large-scale national database. ⋯ This analysis suggests no significant difference in the need for surgical rescue, complication, or mortality between primary MMAE, adjunct MMAE, and rescue MMAE. Additionally, primary MMAE is associated with a significantly lower need for surgical rescue than primary surgery.
