Purpose
Spinal dural arteriovenous fistulas (sDAVF) are the most common spinal vascular lesions. The arterialization of the recipient vein results in venous hypertension and chronic ischemia. Intravascular injection of acrylic glue in order to occlude the draining vein is the principle of endovascular treatment, but a significant portion of embolization procedures do not succeed. We present our initial experience of endovascular balloon augmented embolization of sDAVF using a dual-lumen balloon.Clinical presentation
Three patients harboring sDAVF were submitted to endovascular treatment by onyx injection assisted by a double-lumen balloon as the sole therapy. Control angiography demonstrated complete obliteration of the fistula in all cases with clinical improvement.Conclusion
Dual-lumen balloon onyx embolization of spinal dural arteriovenous fistulas appears to be an acceptable and feasible alternative. 相似文献5.

目的对表现为蛛网膜下腔出血的高颈段硬脊膜动静脉瘘发病机制进行分析,预测出血因素,避免漏诊,指导治疗。方法对5例表现为蛛网膜下腔出血的高颈段硬脊膜动静脉瘘的临床资料进行总结。结果5例瘘口均位于枕大孔区~颈2节段,由椎动脉脊膜支供血.通过髓周静脉引流。所有5例引流静脉均向颅内引流,有不同程度扩张,3例伴有静脉瘤样改变。手术后复合瘘口均消火,4例治愈,1例死亡。结论高颈段硬脊膜动静脉瘘向颅内引流并伴有引流静脉扩张易出血,颅内压增高可能是诱发出血的因素。血管造影应全面,避免小部分蛛网膜下腔出血的患者造影假阴性。手术夹闭瘘口并切断近端引流静脉是可靠的治疗方法。 相似文献

Spinal dural arteriovenous fistula (SDAVF) is a relatively common acquired vascular malformation of the spinal cord. Assessment of a SDAVF is often difficult because of non-specific findings on non-invasive imaging modalities. Diagnosis of a SDAVF is often delayed, and some patients receive unnecessary treatment and treatment delays, often resulting in a poor outcome. The aim of this study was to characterize the clinical presentation, typical imaging findings, and long-term outcome of SDAVF. Forty patients (13 women, 27 men; mean age 58.18 ± standard deviation 14.75 years) who were treated at our hospital from June 1992 to March 2014 were retrospectively reviewed. We investigated the baseline characteristics, clinical presentation, imaging findings, treatment modalities, and outcome of the patients. The most common clinical presentation was a sensory symptom (80%), followed by motor weakness (70%), and sphincter dysfunction (62.5%). Roughly one-third (32.5%) of patients had a stepwise progression of fluctuating weakness and sensory symptoms, but the most common presentation was chronic progressive myelopathic symptoms (47.5%). Thirty-four patients (85%) had T2 signal change on the spinal cord MRI, indicative of cord edema. Thirty-eight patients had typical perimedullary vessel flow voids on T2-weighted MRI. Twenty-eight patients were treated with endovascular embolization, five patients underwent surgery, and four patients underwent both. Clinical outcome was determined by severity of initial deficit (p = 0.008), extent of cord edema (p = 0.010), treatment failure (p = 0.004), and a residual fistula (p = 0.017). SDAVF causes a treatable myelopathy, so early diagnosis and intervention is essential. 相似文献

Long-term follow-up and outcome in patients treated for spinal dural arteriovenous fistula 总被引:7,自引:0,他引:7
Clinical outcome was examined in 21 patients treated for spinal dural arteriovenous fistula after 5–50 months. We compared
the neurological condition (motor function, pain, sensory disturbance, vegetative dysfunction) and Barthel index before and
after fistula occlusion. Neurological impairment was assessed as improved, unchanged, or deteriorated. All patients initially
showed paraparesis of varying degree, and a sensory loss with a defined level in 81% before treatment. The greatest postoperative
change that we measured was in motor activity (67% improved), and the most important deterioration was in male potency (28%
deteriorated). We observed unchanged or absent symptoms in pain in 71% of our patients. We were thus able not only to stop
but even to reverse the progression of symptoms and the degree of disability. On average, neurological symptoms stabilized
within 1 year. The results of this study confirm that spinal dural arteriovenous fistula should be treated as early as possible
after diagnosis.

Long-term surgical outcomes of patients with delayed diagnosis of spinal dural arteriovenous fistula
Spinal dural arteriovenous fistula (dAVF) is an extremely rare vascular entity that is usually misdiagnosed. We sought to determine the long-term clinical outcomes of patients undergoing microsurgical treatment for delayed diagnosis of spinal dAVF. This retrospective study identified patients with delayed diagnosed spinal dAVF at our institution from 2009 to 2018. Patients’ data, including demographics, imaging, and follow-up data, were evaluated. This cohort included 65 consecutive patients with 68 dAVFs and a male-to-female ratio of 4:1 and a mean age of 53.5 ± 13.7 years. The presenting symptoms consisted of limb weakness (n = 42, 64.6%), paraparesis (n = 34, 52.3%), sphincter disturbances (n = 8, 12.3%), and pain (n = 13, 20.0%). The proportion of patients with each symptom significantly increased and patients experienced increased disability when the diagnosis was finalized. The mean length of delay of diagnosis was 20.7 ± 30.0 months. Surgery resulted in complete occlusion of the fistula on the first attempt in all patients. Three patients developed recurrent fistulas, and three died in the follow-up period. Improved motor function was achieved in 38 patients (59.5%). Other symptoms, such as sensory disorders, sphincter dysfunction, and pain, improved by 37.3%, 32.3%, and 66.7%, respectively. Patients with spinal dAVF usually exhibit progressive ascending myelopathy and often remain misdiagnosed for months to years. Some patients’ increased disability cannot be reversed through surgery. 相似文献
