A case of right-sided frontal intracerebral arteriovenous malformation fed mainly by both ethmoidal arteries is reported. The nidus was located intracerebrally, although its main feeders were dural arteries. It was drained partially through an intracerebral abnormal vein with aneurysmal dilatation of its proximal portion into the vein of Rosenthal and the straight sinus. An acute spontaneous intracerebral hematoma was the cause of the clinical symptoms. The etiology, neuroradiology, and surgical treatment of this rare entity are discussed. 相似文献

Dural arteriovenous fistulas (DAVF) involving the craniocervical junction are uncommon lesions that may result in neurological deficits referable to posterior fossa structures and/or the spinal cord. We report on two patients with craniocervical junction DAVF whose venous drainage involved the cervical spinal cord. Both cases presented with progressive quadriparesis and parenchymal magnetic resonance signal abnormality of the cervical spinal cord. Both patients improved following embolization of the fistulas. AVF of the craniocervical junction are an uncommon, but important cause of treatable neurological deficits referable to this region of the nervous system. 相似文献

BACKGROUND Ethmoidal dural arteriovenous fistulas (EDAFs) are an unusual type of intracranial vascular lesion that commonly present with acute hemorrhage. They are often best treated surgically; however, recent endovascular advances raise questions concerning the best therapeutic approach. METHODS We present 7 cases of EDAFs managed at this institution over a 6-year period, which demonstrate the broad spectrum of clinical behavior associated with the lesions. Four patients presented with intracranial hemorrhage, 1 patient with rapidly progressive dementia, 1 patient with a proptotic, red eye, and 1 with a retro-orbital headache. RESULTS One patient underwent no treatment, 1 underwent embolization alone, 2 underwent embolization and resection, and 3 patients underwent resection alone. There was complete obliteration of the EDAF in all of the patients who underwent surgical resection. Embolization was performed through the external carotid circulation and not the ophthalmic artery. There were no treatment-related neurologic deficits. CONCLUSIONS Treatment is best managed with a multidisciplinary approach, which emphasizes complete resection of the lesions with assistance from interventional neuroradiology techniques. However, each patient must be evaluated independently as treatment may vary depending on the angioarchitecture of the lesion. 相似文献

Background Dural arteriovenous fistulas (dAVFs) are usually idiopathic lesions. While individual case reports have documented the occurrence of dAVFs in conjunction with benign meningeal tumors, a detailed characterization of this association is lacking. The objective of this study was to critically examine the relationship between benign meningeal tumors and dAVFs. Methods We performed a retrospective review of records at two institutions, identified patients with coexisting benign meningeal tumors and dAVFs at the time of clinical presentation, and examined various clinical, anatomical and radiographic characteristics. Results Ten patients (4.6 %) had coexisting benign meningeal tumors and dAVFs. The most common tumor was meningioma (90 %). Nine patients were symptomatic: five from tumor, three from dAVF, and one from both tumor and dAVF. All dAVFs were related to the meningeal tumor. Conclusions Benign meningeal tumors may be associated with dAVFs that are either in direct anatomical relation to the tumor or in distant anatomical locations. The increased propensity for development of dAVFs in patients with benign meningeal tumors may be due to multiple factors. Due to this association, additional imaging to exclude dAVFs could be considered in patients with meningeal tumors if exuberant vessels or flow voids are identified on routinely obtained magnetic resonance imaging scans. 相似文献

Intracranial dural arteriovenous fistulas (DAVFs) are relatively rare lesions consisting of anomalous connections between dural arteries and venous sinuses and/or cortical veins. Their clinical presentation is quite variable, with symptoms dependent on their location and venous drainage pattern. Lesions with cortical venous drainage, however, have the highest risk of causing the most significant morbidity and mortality. This places an emphasis on promptly suspecting and diagnosing these lesions. This review highlights the etiology, epidemiology, clinical presentation, and clinical course of patients with intracranial DAVFs. 相似文献

Opinion statement The treatment of dural fistulas is varied and complex. Treatment decisions require consideration of the nature of the symptoms,
the location of the lesion, the complexity of the angioarchitecture, and the risk of progression. Standard treatment modalities
include compression therapy, endovascular embolization, neurosurgery, and radiosurgery. Complex lesions will often require
multiple different interventions. Because dural fistulas may present with a variety of neurologic and ophthalmologic problems,
a team of neurologists, neuro-ophthalmologists, neuroradiologists, and neurosurgeons should develop a comprehensive treatment
plan. 相似文献

Dural arteriovenous malformations in the anterior cranial fossa are rare and are especially prone to haemorrhage. These lesions are usually treated by surgical excision. We report the embolization of an anterior cranial fossa DAVM using an endovascular approach via the ophthalmic artery. 相似文献

A review of the literature reveals that aggressive treatment of symptomatic intrarenal arteriovenous fistulas, whether by surgical or radiologic techniques, is generally indicated. The exception is those fistulas which result from closed renal biopsy since these usually heal spontaneously. The ultimate goal of any form of therapy is the maximal preservation of renal tissue. Methods of treatment are discussed, and a review of classification, etiology, incidence, symptoms, physiologic consequences, and means of diagnosis is given. A case of post-traumatic intrarenal arteriovenous fistula with ipsilaterally elevated renal vein renin and hypertension, cured by partial nephrectomy, is presented. 相似文献
