Spinal arteriovenous fistula (SAVF), including spinal dural arteriovenous fistula and spinal extradural arteriovenous fistula (SEAVF), is a rare spinal vascular disorder characterized by abnormal intradural and extradural arteriovenous shunting, often resulting in progressive motor, sensory, and autonomic dysfunction. Due to its nonspecific presentation and overlapping imaging findings with other spinal diseases, SAVF is frequently misdiagnosed, delaying appropriate treatment and increasing the risk of neurological deterioration. Here, we present a case in which heavily T2-weighted imaging and dynamic contrast-enhanced magnetic resonance angiography at 3T were valuable for the diagnosis of SEAVF.

Purpose: This study aimed to evaluate the prognostic value of thrombus stiffness, measured by strain elastography, in independently predicting the success of endovascular treatment for thrombosed hemodialysis fistulas.
Methods: The study employed a retrospective observational design. Forty-nine patients with chronic kidney disease undergoing hemodialysis and experiencing fistula dysfunction were included.

A patient in their early 60s presented with a headache and right-sided numbness. Imaging revealed a hemorrhagic lesion in the left thalamus and venous engorgement involving the left sphenoparietal sinus, with drainage through the basal vein of Rosenthal and the superficial middle cerebral vein. The trans-Galen approach was utilized for embolization, successfully obliterating the fistulas using coils without retrograde opacification.

Purpose: To describe a case of abnormal fusion between the long P1 segment of the posterior cerebral artery (PCA) and the long posterior communicating artery (PCoA) diagnosed by magnetic resonance angiography (MRA).
Methods: An 83-year-old woman with left pulsatile tinnitus underwent cranial MRA using a 3-Tesla scanner. MRA was performed using a standard 3-dimensional time-of-flight technique.

Background: Cryptogenic stroke constitutes approximately 40% of ischemic strokes in young adults, imposing a significant socioeconomic burden. However, the source of embolus has been specifically investigated in a few number of studies. In this report, We document the first case of a cryptogenic stroke associated with a pulmonary arteriovenous fistula (PAVF), providing evidence of mural thrombus formation within the PAVF vessel.

Background Traditionally, transfemoral and conventional trans-radial access sites have been used in coronary interventions. While the former is prone to complications like bleeding, hematoma, arteriovenous (AV) fistula, and increased morbidity and mortality, the latter is associated with instances of spasm and occlusion of the artery and compartment syndrome. Distal radial and ulnar access have recently been explored as alternative access sites.
