Middle meningeal artery embolization (MMAE) for the management of chronic subdural hematoma (cSDH) has been suggested as a preferred treatment in patients where reinitiating antithrombotic (AT) therapy is necessary. In this study, we evaluate whether reinitiating AT therapy before cSDH resolution after MMAE affects radiographic and clinical resolution. ⋯ Reinitiating AT therapy before cSDH resolution was associated with decreased rates of resolution, but comparable rates of reoperation and residual symptoms. Our results support the cautious reinitiation of AT therapy in patients requiring it after MMAE.

Venous air embolism (VAE) can cause significant morbidity and mortality. Prevention and management of VAE include cessation of air entrainment, positioning changes, and hemodynamic support. The degree to which position change and cardiac output (CO) moderate resolution of intracardiac air has not been rigorously studied using contemporary transesophageal echocardiography (TEE). ⋯ During VAE, both patient position and CO can significantly affect how bubbles move through intracardiac chambers. However, augmenting CO during VAE may be clinically more feasible, efficient, and productive than changing positioning-especially during crises unless the changing in position is intended to halt the entrainment of air. Further TEE studies of intravascular air movement affected by other position changes (lateral, reverse Trendelenburg) and vasopressors should be considered.

In patients experiencing pain secondary to pathological compression fractures, balloon-assisted kyphoplasty and subsequent stereotactic body radiation therapy (SBRT) may allow for restoration of vertebral height and irradiation of the underlying malignancy to control local disease progression. The aim of this study was to evaluate the safety and efficacy of kyphoplasty treatment before SBRT in patients with spinal metastases and benign tumors. ⋯ The combined kyphoplasty and SBRT treatment paradigm can be used to treat patients with painful pathological compression fractures. Long-term LC and patient-reported improvement in pain were observed without the morbidity associated with open surgery.

Understanding sport-related concussion (SRC) mechanisms can aid in prevention and treatment. Concussions in basketball have received relatively less attention compared with collision sports. In a cohort of concussed high school basketball players, this pilot study sought to (1) describe the mechanisms of how concussions occur in basketball and (2) assess the relationship between mechanisms and acute symptomatology and recovery time. ⋯ In this pilot study of concussed high school basketball players, head-to-ground was the most common concussion mechanism, with similar rates during offensive and defensive plays. Although head-to-body contact increased acute symptoms, other mechanisms did not predict recovery time. Given the limited information on concussions in basketball, the preliminary results of this pilot study may help inform larger studies on basketball SRC mechanisms.
