Article Abstract
Parasagittal sinus dural arteriovenous fistulas (DAVFs) are rare and aggressive vascular malformations with a high risk of intracranial hemorrhage (ICH). We present the case of a 75-year-old man with altered consciousness, anisocoria, and left hemiparesis due to a large subcortical ICH. Imaging revealed a ruptured varix associated with a parasagittal sinus DAVF (Cognard type IV, Borden type III). The patient underwent emergency hematoma evacuation, followed by successful transarterial embolization via the contralateral middle meningeal artery (MMA) using N-butyl-2-cyanoacrylate. Despite complete angiographic obliteration, the clinical outcome was poor. Parasagittal sinus DAVFs should be considered in the differential diagnosis of large subcortical hemorrhages. It should also be noted that certain cases may result in unfavorable clinical outcomes. When ipsilateral arterial access is unavailable, a contralateral approach via the MMA can be effective.

Background And Purpose: Superior sagittal sinus (SSS) dural arteriovenous fistulas (DAVFs) are sinus-type fistulas with shunting point(s) centered on the sinus or parallel parasinus wall, while its counterpart parasagittal DAVFs are non-sinus-type fistulas with shunting point(s) centered on the junctional zone of the bridging vein and the SSS. SSS DAVFs can be challenging to treat due to the widespread shunting zone, eloquence of the involved venous structure and their rarity. We explore the clinical data, imaging characteristics, endovascular treatment modalities and treatment outcomes of SSS DAVF, with the aim of identifying the ideal treatment strategies.

Introduction: Dural sinus venous thrombosis in postpartum women is a well known complication, but intracranial venous lake thrombosis (IVLT) has not been previously described, nor its association with intracranial hypotension following epidural anesthesia (EDA). This study aims to describe and characterize a cohort of patients with IVLT with regards to imaging findings and symptoms.
Materials And Methods: This retrospective study included patients from the picture and archiving communication system based on search strategies from referral text including: "headache + EDA", "complicated EDA", "post dural puncture headache", "childbirth + headache", "delivery + headache" between November 2005 and June 2024.

Background: Non-sinus type parasagittal dural arteriovenous fistula (DAVF) is associated with a high incidence of cortical venous reflux and is susceptible to the development of progressive symptoms, including venous infarction and cerebral hemorrhage. Well-developed superficial temporal arteries (STAs) and/or occipital arteries (OAs) are frequently involved, which present a challenge in controlling liquid embolic material when injecting liquid embolic material from the middle meningeal artery (MMA). We developed a method to control the feeding from cutaneous vessels using a circular plastic disc and a rubber band.
