Morphological Effect on Wall Shear Stress in Intracranial Aneurysms.

Background And Study Aims:  Both high and low wall shear stress (WSS) play important roles in the development and rupture of intracranial aneurysms (IAs). This study aimed to determine the morphological factors that affect WSS in the IA and the parent artery.

Material And Methods:  We studied a total of 66 IAs with three-dimensional imaging.

Serum caspase-cleaved cytokeratin-18 levels and outcomes after aneurysmal subarachnoid hemorrhage.

Objective: Cell apoptosis is involved in acute brain injury after aneurysmal subarachnoid hemorrhage (aSAH). The protein cytokeratin-18 (CK-18) is cleaved by the action of caspases during apoptosis, and the resulting fragments are released into the blood as caspase-cleaved CK (CCCK)-18. Our study examined the relationship between circulating CCCK-18 levels and long-term clinical outcomes among aSAH patients.

[Correlative factors of traumatic embolism in superficial cerebral vein].

Objective: To analyze the correlative factors of traumatic embolism in superficial cerebral vein and explore their corresponding treatments.

Methods: A total of 74 cases were divided into 3 groups according to their injury mechanisms. Group A: traumatic brain injury in superficial cerebral vein with cerebral contusion, acute intracerebral hematoma and subdural hematoma in the same place; Group B: traumatic brain injury in superficial cerebral vein with acute intracerebral hematoma, subdural hematoma and skull fracture in the same place; Group C: traumatic brain injury in superficial cerebral vein with acute subdural hematoma and skull fracture in the same place, without cerebral contusion or acute intracerebral hematoma.
