A well-documented association exists between the vasa vasorum and vasopathologies, including atherosclerosis. However, information on the role of the vasa vasorum during vascular degenerative changes of vasospasm after subarachnoid hemorrhage (SAH) is insufficient. ⋯ The vasa vasorum and their vasospasm play a crucial role in the pathogenesis of basilar artery degeneration in the vasospasm following SAH.

Minimally invasive surgical techniques may have beneficial effects on spontaneous intracerebral hemorrhage. Accurate localization of the hematoma and real-time guided puncture are more important in minimally invasive surgical procedures than in traditional craniotomy. Here, we introduce a novel simple puncture positioning and guidance system for intracerebral hematoma and demonstrate its utility for hematoma puncture surgery in a simulation experiment and series of patients. ⋯ We demonstrate a novel simple puncture positioning and guidance system that has the advantages of simplicity, low-cost, device availability, and individual real-time guidance. We believe this system may be useful in resource-limited centers where navigation is not available.

Pituitary stalk sectioning is only essential in cases of craniopharyngioma originating from the stalk or metastatic tumor to the stalk. Some patients can discontinue postoperative antidiuretic hormone (ADH) supplementation with special conditions. ⋯ Total removal was achieved in 91% of all cases. Half of the patients could discontinue ADH supplementation, which was associated with preservation of thyroid function. The findings of hypothalamic enhancement on postoperative MRI may be associated with recovery from DI.
