Recent advances in angiographic technique have raised our awareness of the presence of unruptured intracranial aneurysms (UIAs). However, the appropriate management for these lesions remains controversial. To optimize patient outcomes, the physician must weigh aneurysmal rupture risk associated with observation against the complication risks associated with(More)
bilateral thalamic infarctions are rare and usually caused by vascular occlusions. When symptomatic, it is important to make a distinction between different vascular etiologies in order to provide an effective and timely therapeutic response. Clinical presentations may not adequately differentiate between the vascular etiologies alone. It is therefore(More)
Early treatment of ischemic stroke with thrombolytics is associated with improved outcomes, but few stroke patients receive thrombolytic treatment in part due to the 3-hour time window. Advances in neuroimaging may help to aid in the selection of patients who may still benefit from thrombolytic treatment beyond conventional time-based guidelines. In this(More)
Epistaxis is a common clinical complaint with a spectrum of severity ranging from spontaneous cessation to unrelenting, life threatening hemorrhage requiring surgical treatment. Both otolaryngologic and neurointerventional techniques are discussed to provide a comprehensive paradigm to treat patients with epistaxis. An exhaustive review of the anatomic(More)
OBJECTIVE Intracranial aneurysms are a public health issue with a potential for rupturing, causing significant morbidity/mortality. The prevalence of unruptured intracranial aneurysms, including those that are asymptomatic, varies widely, as it has been determined through autopsy studies as well as conventional angiography. However, computed tomography(More)
Vertebral artery origin anomalies are typically incidental findings during angiography or post mortem examination. We present two cases of vertebral origin from the right common carotid artery in association with an aberrant right subclavian artery. We also review the embryonic development and the clinical significance of this anomaly.
BACKGROUND Management of vascular tumors of the head, neck, and brain is often complex and requires a multidisciplinary approach. Peri-operative embolization of vascular tumors may help to reduce intra-operative bleeding and operative times and have thus become an integral part of the management of these tumors. Advances in catheter and non-catheter based(More)
Elevated intracranial pressure in patients with chronic renal failure has several potential causes. Its rare occurrence secondary to the hemodynamic effects of hemodialysis is described and the findings support a multifactorial etiology ("two hits").
BACKGROUND Recent studies have documented the high sensitivity of computed tomography angiography (CTA) in detecting a ruptured aneurysm in the presence of acute subarachnoid hemorrhage (SAH). The practice of digital subtraction angiography (DSA) when CTA does not reveal an aneurysm has thus been called into question. OBJECTIVE We examined this dilemma(More)
The field of neurointerventional surgery has grown in recent years. Endovascular therapies for both ischemic stroke and intracranial aneurysms have become important components in the multimodal treatment of these conditions. Familiarity with these treatment options by general neurologists is important for patient care. This article reviews recent trials and(More)
