Case Reports
Nonaneurysmal Perimesencephalic Subarachnoid Hemorrhage Associated with an Anomalous Anastomotic Cisternal Vein.
A 54-year-old woman with no relevant medical history presented with severe headache, nausea, and vomiting for 8 days. Imaging examination revealed a subarachnoid hemorrhage in the left interpeduncular cistern without aneurysms. ⋯ In the primitive pattern, the basal vein of Rosenthal drains into the lateral mesencephalic vein and to the petrosal sinus. This anomalous flow may predispose to subarachnoid hemorrhage, emphasizing the association between nonaneurysmal perimesencephalic hemorrhage and venous anomalies.

The prior trials investigating triple-H therapy for preventing delayed cerebral ischemia (DCI) enrolled patients with aneurysmal subarachnoid hemorrhage (aSAH) who underwent early aneurysm therapy within 3 days. However, surgical clipping might be performed during 4-7 days that high incidence cerebral vasospasm is likely. We examined effects of hypervolemia-augmented blood pressure (HV-ABP) protocol on DCI prevention when clipping was delayed. ⋯ Achieving the targets recommended in the HV-ABP protocol was associated with reducing the DCI incidence in patients with aSAH who underwent delayed clipping.

Randomized Controlled Trial Multicenter StudyAssociation of Fluid Balance and Hemoglobin Decline With Neurological Outcome After Aneurysmal Subarachnoid Hemorrhage.
To explore the relationship between fluid balance and hemoglobin decline with secondary infarctions and neurologic outcome in aneurysmal subarachnoid hemorrhage (aSAH) patients. ⋯ Increased fluid balance influences hemoglobin decline through hemodilution. Fluid overload, rather than a slight decrease in hemoglobin levels, appears to be the primary factor contributing to poor outcomes in aSAH patients. The results suggest aiming for euvolemia and that a modest hemoglobin decline may be tolerated. It may be advisable to adopt a restrictive approach to transfusions, as they can potentially have a negative effect on outcome.

The Link between Vitamin D and the Risk of Aneurysmal Subarachnoid Hemorrhage: A Systematic Review.
Vitamin D (VD) is one of the fat-soluble vitamins proposed to be associated with aSAH. According to the clinical evidence, this investigation explores the link between VD concentrations and clinical outcomes in aSAH patients. ⋯ This study highlights the complex association between VD concentration and the risk of aSAH. The observed inconsistencies in study outcomes suggest that the relationship between VD and aSAH is multifaceted and may be influenced by various factors, including study population, geographical location, and methodological approach.
