The artery to trigeminal nerve ganglion has been identified as a branch that arises from the extracranial segment of middle meningeal artery prior to entry into the foramen spinosum. The role of the artery in being the arterial supply to trigeminal nerve ganglion is supported by electrophysiological and clinical suppression of trigeminal nerve activity during selective intra-arterial injection of anesthetics.

Several studies using Doppler ultrasound have suggested cerebral venous drainage is through paravertebral venous plexus due to the collapse of internal jugular veins in an upright position. ⋯ Our results demonstrate prominent changes in venous drainage patterns during upright angiographic images. Further studies would have to identify the patients in whom additional information in the upright angiography may provide clinically relevant information.

Endovascular Treatment of Spontaneous Intracranial Internal Carotid Dissection in a Young Patient Affected by Systemic Lupus Erythematosus: A Case Report.
Systemic lupus erythematosus (SLE) increases the risk of cerebrovascular events due to vascular changes, resulting in the weakening of the vessel walls. Moreover, patients with SLE have more incidence of arterial lesions such as dissections. Internal carotid dissection (ICA) is an infrequent cause of ischemic stroke, representing 2% of all ischemic events. ⋯ ICA dissection with consequent ischemic stroke is an unusual first presentation of SLE disease. Our case highlights how, despite an infrequent occurrence, ICA dissection should be considered for young adults presenting with ischemic stroke, especially in those affected by SLE. This paper also shows the good technical result in the use of stenting in case of intracranial ICA dissection.

Long Acting Liposomal Bupivacaine for Percutaneous Sympathetic Stellate Ganglion Blockade: A Technical Note.
We describe the use of long acting liposomal bupivacaine for percutaneous stellate ganglion blockade to treat severe headaches following internal carotid artery dissection. ⋯ Liposomal bupivacaine injection for stellate ganglion blockade can result in a more prolonged effect compared with bupivacaine hydrochloride.

Chronic Traumatic Encephalopathy in Athletes Involved with High-impact Sports.
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease occurring most commonly in athletes and is caused by repeated concussive or subconcussive blows to the head. The main purpose of this review is to evaluate the published literature on chronic traumatic encephalopathy (CTE) in athletes participating in high-impact sports. In particular, we highlight the significance of concussive and subconcussive impacts in multiple sports, elucidate the differences between clinical/pathological features of CTE and related neurodegenerative diseases, and provide an explanation for the variation in clinical presentation between athletes of different sports. ⋯ Further longitudinal studies should be conducted to correlate the number of suffered concussive/subconcussive forces to the likelihood of developing chronic traumatic brain injury symptoms. Research striving for a reliable antemortem CTE diagnosis would be immensely beneficial, leading to more accurate estimates of prevalence, allowing clinicians to assess future risk of athletes' continued participation in sports, and enabling clinicians to make appropriate preventive recommendations.
