<i>Background:</i> Endoscopic third ventriculostomy (ETV) has gained wide popularity as a first-line treatment for obstructive hydrocephalus (OHC). We have been performing ETV since 1998. We report our experience with this technique in the management of OHC. <i>Methods:</i> Between 1998 and 2007, we performed 49 ETV procedures in 46 patients suffering from OHC. Medical records were retrospectively reviewed. Success was defined as shunt-free survival. <i>Results:</i> There ...

BACKGROUND AND IMPORTANCE: High-grade cavernous sinus (CS) dural arteriovenous fistulae with cortical venous drainage often have a malignant presentation requiring urgent treatment. In the absence of a venous access to the lesion, transarterial embolization can potentially cure these lesions; however, the high concentration of eloquent arterial territories adjacent to the fistula creates a precarious risk of arterial-arterial reflux. In such cases, a combined surgical and endovascular approach may ...

Neurointerventional surgery offers the potential to deliver remarkable intravascular therapies for various neurovascular diseases and stroke. This approach, however, carries a risk of complications that need to be kept to a minimum. Thromboembolism is one of the most consequential complications of neurointerventional surgery in the treatment of intracranial aneurysms. Both antiplatelet and anticoagulant therapies have shown to reduce the risk of thromboembolism in this setting. In this paper, we ...

Arterial dissections of head and neck arteries were first identified pathologically in the 1950s, but not until the 1970s and the 1980s did they begin to be widely recognized as a clinical entity. Carotid and vertebral artery dissections account for only 2% of all ischemic strokes, but they account for approximately 20% of thromboembolic strokes in patients younger than 45 years. The cause of supra-aortic dissections can be either spontaneous or traumatic. This article addresses spontaneous cervical ...

We applied 4D flow magnetic resonance imaging (MRI) for the detailed evaluation of AVM function at baseline and to investigate the impact of staged embolization on AVM hemodynamics in a patient with a Spetzler‐Martin grade III AVM. The patient underwent three embolization procedures resulting in >50% nidal casting and obliteration of several arteriovenous fistulae. 4D flow MRI ...

When occurring in the skull base, their treatment is limited by proximity to critical neurovascular structures. Open surgical approaches can carry high morbidity, making the development of alternative approaches desirable.

The accepted standard of treatment for chordomas of the mobile spine, which includes en-bloc resection with wide margins, cannot be easily applied to the chordomas of the skull base because of their proximity to critical neurovascular structures.

Abstract BACKGROUND Aneurysm recurrence after coiling has been associated with aneurysm growth, (re)hemorrhage, and a greater need for follow-up. The second-generation HydroCoil Embolic System (HES; MicroVention, Inc) consists of a platinum core with integrated hydrogel and was developed to reduce recurrence through enhancing packing density and healing within the aneurysm. OBJECTIVE To compare recurrence between the second-generation HES and bare platinum coil (BPC) in the new-generation Hydrogel ...
