Background: Endovascular embolization of the middle meningeal artery (MMA) has emerged as an adjunctive and stand-alone modality for the management of chronic subdural hematomas (cSDH). We report our experience utilizing proximal MMA coil embolization to augment cSDH devascularization in MMA embolization.
Methods: MMA embolization cases with adjunctive proximal MMA coiling were retrospectively identified from a prospectively maintained IRB-approved database of the senior authors.
Results: Of the 137 cases, all patients (n = 89, 100%) were symptomatic and underwent an MMA embolization procedure for cSDH. 50 of the patients underwent bilateral embolizations, with 53% (n = 72) for left-sided and 47% (n = 65) for right-sided cSDH. The anterior MMA branch was embolized in 19 (14%), posterior in 16 (12%), and both in 102 (74.5%) cases. Penetration of the liquid embolic to the contralateral MMA or into the falx was present in 38 (28%) and 31 (23%) cases, respectively, and 46 (34%) cases had ophthalmic or petrous collateral (n = 41, 30%) branches. MMA branches coiled include the primary trunk (25.5%, n = 35), primary and anterior or posterior MMA trunks (20%, n = 28), or primary with the anterior and posterior trunks (54%, n = 74). A mild ipsilateral facial nerve palsy was reported, which remained stable at discharge and follow-up. Absence of anterograde flow in the MMA occurred in 137 (100%) cases, and no cases required periprocedural rescue surgery for cSDH evacuation. The average follow-up length was 170 ± 17.9 days, cSDH was reduced by 4.24 ± 0.5(mm) and the midline shift by 1.46 ± 0.27(mm). Complete resolution was achieved in 63 (46.0%) cases.
Conclusion: Proximal MMA coil embolization is a safe technique for providing additional embolization/occlusion of the MMA in cSDH embolization procedures. Further studies are needed to evaluate the potential added efficacy of this technique.

Bilateral chronic subdural hematoma (bCSDH) represents a common neurosurgical entity frequently associated with elevated retreatment rates. However, the underlying mechanisms driving its high recurrence remain incompletely understood. Emerging evidence implicates the middle meningeal artery (MMA) in the pathogenesis and progression of chronic subdural hematomas.

Spontaneous intracranial hypotension (SIH) is caused by cerebrospinal fluid leak and has an incidence of approximately five per 100,000 person-years. SIH leads to a range of clinical symptoms, from debilitating postural headaches to subdural hematomas (SDHs). The pathophysiology of the disease is not fully understood, but has garnered interest in recent years.

Objective: Non-acute subdural hematomas (NASDHs) often recur or persist, particularly among older patients with comorbidities. Middle meningeal artery embolization (MMAe) has emerged as a promising primary treatment alternative. Dual-lumen balloon microcatheters significantly reduce the risk of reflux, which is a limitation of single-lumen microcatheters.

Monomelic amyotrophy (MMA) is a lower motor neuron predominant disorder affecting an upper limb, which can mimic amyotrophic lateral sclerosis (ALS). It often presents with unilateral, distal upper limb weakness and atrophy, whose trajectory is one of an initial period of progression followed by a prolonged plateau, as opposed to the typically relentless progression as is seen in ALS. This case report describes a novel observation of a patient with MMA with an unexplained ipsilateral partial Horner's syndrome (miosis and ptosis).

Mitochondrial dysfunction is increasingly recognized as a driver of sarcopenia pathogenesis, progression, and prognosis. Muscle mass is a fundamental and objective component of sarcopenia. In some studies, relative muscle loss has been used to define sarcopenia.
