OBJECT Intracranial-to-intracranial (IC-IC) bypasses are alternatives to traditional extracranial-to-intracranial (EC-IC) bypasses to reanastomose parent arteries, reimplant efferent branches, revascularize branches with in situ donor arteries, and reconstruct bifurcations with interposition grafts that are entirely intracranial. These bypasses represent an(More)
INTRODUCTION Emergent surgery on a ruptured brain arteriovenous malformation (AVM) is indicated for a large hematoma in an acutely deteriorating patient. The majority of ruptured AVMs, however, present in clinically stable patients with neurological deficits. Controversy exists with respect to the timing of treatment for ruptured AVMs in these stable(More)
BACKGROUND AND PURPOSE The role of flow diversion in the management of aneurysms remains unknown. We sought to evaluate the community agreement regarding indications for flow diversion. MATERIALS AND METHODS A portfolio of 35 difficult aneurysm cases was sent to 40 clinicians with varying backgrounds and experience. Responders were asked whether they(More)
BACKGROUND Recurrence of chronic subdural haematomas (CSDHs) after surgical drainage is a significant problem with rates up to 20%. This study focuses on determining factors predictive of haematoma recurrence and presents a scoring system stratifying recurrence risk for individual patients. METHODS Between the years 2005 and 2009, 331 consecutive patients(More)
Patients harboring brain arteriovenous malformation (bAVM) are at life-threatening risk of rupture and intracranial hemorrhage (ICH). The pathogenesis of bAVM has not been completely understood. Current treatment options are invasive, and ≈ 20 % of patients are not offered interventional therapy because of excessive treatment risk. There are no specific(More)
BACKGROUND AND PURPOSE Brain arteriovenous malformation (bAVM) is an important risk factor for intracranial hemorrhage. Current therapies are associated with high morbidities. Excessive vascular endothelial growth factor has been implicated in bAVM pathophysiology. Because soluble FLT1 binds to vascular endothelial growth factor with high affinity, we(More)
BACKGROUND AND IMPORTANCE Carotid body tumors are a technically challenging surgical problem. One of the primary goals of surgery and often one of the most difficult aspects of management involves preservation of the ipsilateral internal carotid artery (ICA). We report a small case series with challenging aspects to ICA preservation that were successfully(More)
BACKGROUND AND PURPOSE Flow diversion is a relatively new strategy used to treat complex cerebral aneurysms. The optimal method for radiographic follow-up of patients treated with flow diverters has not been established. The rate and clinical implications of in-stent stenosis for these devices is unclear. We evaluate the use of transcranial Doppler(More)
OBJECTIVE Despite a hemorrhagic presentation, many patients with arteriovenous malformations (AVMs) do not require emergency resection. The timing of definitive management is not standardized in the cerebrovascular community. This study was designed to evaluate the safety of delaying AVM treatment in clinically stable patients with a new hemorrhagic(More)
