Dural arteriovenous fistula (DAVF) is a rare complication of cerebral venous sinus thrombosis (CVST). DAVFs develop as a result of direct arterial to venous sinus communications evolving in response to an occluded sinus. The authors present a patient with Down's syndrome who developed progressive, uncontrolled seizures and chronic CVST secondary to factor V Leiden deficiency. Brain MRI and computerised tomographic venography revealed a complex secondary DAVF, which once embolised resulted in a dramatic reduction in seizures and improvement in the clinical state. DAVFs should be considered as a potential complication in patients with persistent features of CVST.

Cerebral venous thrombosis (CVT) is a rare and complex form of stroke, representing a small percentage of all stroke cases. The disease's clinical presentation is highly variable, involving a wide range of medical specialists due to its diverse manifestations. Over the past decade, significant advancements in understanding CVT have been made, particularly in light of the COVID-19 pandemic and subsequent vaccination efforts.

The purpose of the current study was to determine the angulation of the dural venous sinuses in soft tissue, to evaluate differences between types of tissue, and to discuss the potential influence of these angulations on intracranial venous hemodynamics and related pathologies. Angulations formed in different segments of the transverse, sigmoid, and superior sagittal sinuses were measured in 13 adult human cadaveric heads (26 sides). After the soft tissues were removed, measurements were also taken from the underlying bone.

Background: Intravascular injection of liquid adhesive hemostats is a rare but serious complication that can result in cerebral thromboembolism.
Observations: A 64-year-old female underwent orbitozygomatic craniotomy for posterior communicating artery aneurysm clipping with the routine use of a flowable hemostatic agent during extradural dissection. After placement of the aneurysm clip, flow was confirmed through the parent vessel and nearby branches.

Unlabelled: Right-to-left shunt may be a cause of paradoxical embolization (and cryptogenic cerebral ischemic events). Patent foramen ovale and pulmonary arterio-venous malformations are the most common cause of paradoxical embolization; however, some rare cardiovascular lesions may cause a right-to-left shunt with consequent paradoxical embolization. We describe a case of a young child with superior sinus venosus atrial septal defect who underwent surgical closure and developed a cryptogenic cerebral ischemic attack due to a rare cause of paradoxical embolization, during a long-term follow-up.

The right venous valve is critical to the proper development of the fetal heart. As the right venous valve degenerates later in fetal development, residual structures can remain, such as the terminal crest, Eustachian valve, Thebesian valve, and a prominent Chiari network, with a sail-like appearance resembling a spinnaker. While these structures are often incidentally found on adult echocardiograms, we present a case of a term neonate with hypoxia secondary to a persistent right valve of the sinus venosus.
