Patients with spinal vascular lesions present with unique symptoms and have important anatomical and physiologic changes that must be considered prior to treatment. In this mini-review, we provide an overview of normal spinal vascular anatomy and discuss several key spinal vascular lesions. We provide an overview of cavernous malformations, intradural arteriovenous malformations, perimedullary ...

PURPOSE To examine the clinical and radiographic findings in a large group of patients having or suspected of having a spinal dural arteriovenous fistula. METHODS An analysis of 240 spinal angiograms in 132 patients revealed 97 vascular malformations that included 66 spinal dural arteriovenous fistulas. Sixteen patients had 1 or more normal spinal angiograms that were performed for suspected ...

Objective: Recently, the occlusion rate of transarterial embolization (TAE) for intracranial non-sinus-type dural arteriovenous fistulas (NSDAVFs) has improved after ONYX was introduced. Additionally, when TAE NSDAVF is unsuccessful, transvenous (TVE) become available as an alternative treatment. We investigated factor favorable endovascular treatment at our institutions.

Eight patients with dural arteriovenous fistulas involving the deep cerebral venous system were treated by a combination of preoperative embolization, intraoperative embolization, and/or surgical excision. All eight patients were men 30-71 years old (mean age, 48.5). The presenting symptoms were hemorrhage in four patients (two subarachnoid, one intraventricular, and one parenchymal), stroke in...

PURPOSE We report on the evolution in one institution from transarterial embolization for the treatment of dural arteriovenous fistulas of the lateral and sigmoid sinuses to the safer and more durable technique of transvenous endovascular therapy for the majority of these lesions. METHODS Arterial, venous, and combined embolizations were performed for 24 fistulas of the lateral and sigmoid si...

BACKGROUND AND PURPOSE Spinal dural arteriovenous fistulas are a rare entity that, if left untreated, can lead to considerable morbidity with progressive spinal cord symptoms. The aim of this study was to evaluate the clinical outcome of patients with spinal dural arteriovenous fistulas that were primarily treated with endovascular embolization. MATERIALS AND METHODS A retrospective review wa...

AIM The aim of this study to evaluate the feasibility of establishing endovascular neurosurgery in remote resource-poor neuro-hospital setup and evaluate its outcome. MATERIALS AND METHODS Retrospective analysis of diagnostic and therapeutic endovascular neurosurgical procedures performed during September 2013-June 2016. RESULTS A total of 174 diagnostic cerebral and spinal digital subtract...

Intracranial dural carotid cavernous fistulas account for 10 to 15% of all intracranial arteriovenous malformations. Although these fistulas tend to regress spontaneously, permanent neurological deficits are observed in as many as 20-30% of untreated patients. In general, transvenous or transarterial embolization of the fistula is a safe and successful treatment option. Depending on the amount ...

This article describes a number of treatment strategies for the management of perforations that occur during neurointerventional procedures. During the past 5 years, we have performed over 1200 endovascular procedures to treat vascular disorders involving the brain and spinal cord (400 cerebral arteriovenous malformations, 230 tumors, 197 carotid cavernous fistulas, 183 aneurysms, 130 dural fis...
