Summary: Contemporary treatments for spinal cord arteriovenous shunts are primarily based on clinicians' experiences. In a review of 463 patients, complete obliteration rates were 40.6% for the whole cohort, 58.5% after microsurgery, and 26.4% after embolization. The overall rate of treatment-related neurological deficits was 11.2%, with a decrease in clinical deterioration rate from 32.5%/year to 9.3%/year after interventions.

Summary: This study identified C4BPA and C1QA as potential biomarkers for the diagnosis of SDAVF, and revealed that complement pathway activation might be one of the molecular mechanisms for venous hypertension myelopathy.

Summary: This article reports a rare case of intracranial subarachnoid hemorrhage caused by cervical spinal dural fistula. The patient was treated under multidisciplinary team care and made a full recovery with no neurological defects or complications. The experience shared in this case might help improve the diagnosis and management protocol for similar conditions in future patients.

Summary: Neurovascular sonography serves as a valuable tool for screening and follow-up of dural arteriovenous fistulas (dAVFs) in the transverse sinuses/sigmoid sinuses. This case report presents a rare case of bilateral dAVFs diagnosed through neurovascular ultrasonography, which was subsequently confirmed by further imaging. The findings highlight the importance of neurovascular sonography in the diagnosis of dAVFs in the transverse sinuses/sigmoid sinuses.

Summary: A study using the CONDOR registry found that dural arteriovenous fistula-related hemorrhage had relatively lower morbidity and mortality rates in patients compared to other arterialized cerebrovascular lesions. Age and anticoagulant use were identified as risk factors for poor outcomes, while the subtype of hemorrhage and venous shunting pattern did not significantly affect the outcomes.

Summary: This study aimed to identify demographic, clinical, and radiographic variables among patients with failed embolization of type I spinal dAVF. Out of 24 surgeries reviewed, 5 patients underwent open surgery for failed embolization, with all patients achieving definitive radiographic cure at last follow-up. The increased use of endovascular treatment has led to the treatment of refractory cases with a greater degree of surgical complexity.

Summary: Spinal dural arteriovenous fistula (SDAVF) is the most common vascular malformation of the spine, but can be difficult to diagnose due to subtle magnetic resonance imaging signs. In this case study, we present a patient with SDAVF and syringomyelia of the thoracic spinal cord, and hypothesize that the fistula may cause intramedullary fluid accumulation leading to syrinx formation.

Summary: This case report highlights a rare phenomenon of SDAVF with intradural double draining veins, which was successfully treated with surgery. The patient's symptoms improved gradually postoperatively, as demonstrated by significant resolution of edema and enhancement on MRI.

Summary: Anterior falcotentorial junction dural arteriovenous fistulas (AFDAVFs) are the most complex and deeply located type of tentorial fistula, requiring a safer approach for endovascular treatment. Through new angiographic definitions and categorization of AFDAVF nidus and the deep venous system of the brain, the study aims to improve analysis of the malformation and develop a safer endovascular strategy, potentially preventing periprocedural complications and enhancing treatment safety.

Summary: This study reports a rare case of SDAVF, in which a patient experienced rapid exacerbation to complete paraplegia within hours of receiving electroacupuncture treatment. Emergency surgery was performed to address the SDAVF, leading to symptom improvement and the patient's ability to walk post-operatively. Early detection and immediate treatment are crucial for a better outcome in SDAVF cases.

Summary: This study examined the risk factors associated with the recurrence of cranial dural arteriovenous fistulas (dAVFs) after treatment. The study found that the recurrence rate of dAVFs after angiographic cure was 4.5%. Risk factors for recurrence included tentorial location, cortical venous drainage, and deep cerebral venous drainage.

Summary: This study analyzed the reasons for misdiagnosis of spinal dural arteriovenous fistula (SDAVF) by orthopedic surgeons and proposed measures to improve the diagnosis of this disease. The results showed that it is important for orthopedic surgeons to be aware of the specific clinical manifestations and magnetic resonance imaging features of SDAVF, especially in patients with bladder and bowel dysfunction. Timely multidisciplinary teamwork and avoidance of early use of steroids or inappropriate surgery are important measures. This study is of great significance in improving the understanding of SDAVF among orthopedic surgeons.

Summary: The risk of rebleeding in dural arteriovenous fistulas with cortical venous drainage presenting with hemorrhage is increased in the first 2 weeks. However, the magnitude of this increase may be lower than previously thought. Treatment within 5 days appears to be an appropriate timeframe.
