The occurrence of dural arteriovenous fistulas (DAVFs) at the craniocervical junction (CCJ) is an uncommon vascular malformation. The diagnosis and treatment of CCJ DAVFs present a formidable challenge. This study aims to investigate the effect of endovascular embolization and microsurgery on improving patient prognosis. ⋯ CCJ DAVFs are uncommon disorders characterized by a diverse range of clinical manifestations. The functional prognosis of endovascular treatment may be superior to microsurgery.

The treatment of complex intracranial aneurysms with bypass surgery using 2 branches of the superficial temporal artery (STA) proves to be an effective surgical option. However, the harvest of these 2 STA branches, combined with a pterional craniotomy, carries the potential risk of delayed wound healing of the skin flap. This study undertook a retrospective analysis to examine and identify the factors associated with this delayed wound healing. ⋯ In the treatment of complex intracranial aneurysms, where harvesting of the 2 STA branches is involved with a pterional craniotomy, producing a smaller skin flap (L- or T-shaped incision) is effective in minimizing the risk of delayed wound healing. The process of harvesting the STA and closing the wound demands meticulous care, taking into consideration the normal anatomical structures and the subdermal vascular plexus of the scalp.

The ventriculoatrial (VA) shunt is a surgical intervention used to manage hydrocephalus, although it is less often utilized compared to the ventriculoperitoneal (VP) shunt or endoscopic third ventriculostomy. Placement of the distal catheter typically involves the utilization of either the common facial vein (CFV) or the internal jugular vein (IJV), 2 frequently employed options for venous access. This study aims to determine whether there is a statistically significant difference between the long-term patency (2 years) of the distal end of the VA shunt of these 2 options. ⋯ In VA shunt surgery, both the CFV and IJV can be used as venous access sites for the right atrium because there is no discernible difference between their complications or long-term patency. Anatomical considerations, patient-specific characteristics, and the surgeon's preference should all be considered when choosing the venous access location for the placement of a VA shunt.

Distal anterior cerebral artery (dACA) aneurysms are rare. Ruptured dACA aneurysms typically present with subarachnoid hemorrhage in conjunction with intracerebral hematoma and cause neurological deterioration. This study aimed to determine their risk of rupture and examine associated factors. ⋯ Distal anterior cerebral artery (dACA) aneurysms may rupture, even when small. We found a significant difference between ruptured and unruptured aneurysms with respect to maximum diameter, aspect ratio, and size ratio. Treatment for small aneurysms should be considered based on size ratio and aspect ratio, not just size.

This is the first study to evaluate the predictive value of the cervical vertebral bone quality (VBQ) score on zero-profile cage (ZPC)subsidence after anterior cervical discectomy and fusion (ACDF) using the Hounsfield units (HU) value of computed tomography as the reference. ⋯ The VBQ score may be a valuable tool for independently predicting ZPC subsidence after single-level ACDF.
