BACKGROUND AND PURPOSE Time-resolved 3D-DSA (4D-DSA) enables viewing vasculature from any desired angle and time frame. We investigated whether these advantages may facilitate treatment planning and the feasibility of using 4D-DSA as a single imaging technique in AVM/dural arteriovenous fistula radiosurgery. MATERIALS AND METHODS Twenty consecutive patients (8 dural arteriovenous fistulas and...

Intracranial dural arteriovenous fistulas are abnormal communications between higher-pressure arterial circulation and lower-pressure venous circulation. This abnormal communication can result in important and frequently misdiagnosed neurological abnormalities.A case of rapid onset paraplegia following cervical chiropractic manipulation is reviewed. The patient's generalized spinal cord edema, ...

background: spinal dural avf is the most common type of spinal vascular malformation. however, presenting symptoms differ according to site of spinal involvement. this study described a case of arteriovenous malformation with paraparesis and incontinence. case presentation: diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out other...

Appropriate vascular function is essential for the maintenance of central nervous system homeostasis and achieved through virtue blood-brain barrier; a specialized structure consisting endothelial, mural, astrocytic interactions. While appropriate barrier typically achieved, vasculature not infallible cerebrovascular anomalies, collective terminology diverse lesions, are present in meningeal ce...

Introduction: Dural arteriovenous fistulas account for 10 to 15% of intracranial malformations. They are defined as malformations short-circuits between dural and extracranial arteries with venous sinuses. Its presentation is in frequent its management a challenge low- middle-income countries where there difficulties accessing high quality technological tools. Case: We present the case an unusu...

Cerebral arteriovenous fistulas (AVFs) are rare in childhood and are generally associated with arteriovenous malformations (AVMs). They may lead to an increase in intracerebral pressure, seizure, hemorrhage, or cardiac decompression. They may be treated with endovascular embolization. Herein we present the radiological findings, before and after endovascular treatment, of a pediatric patient wi...
