PURPOSE To determine whether color Doppler sonography can be a sensitive alternative to screening arteriography for identifying arterial injury in patients with penetrating traumatic neck injuries. METHODS Fifty-two patients admitted to our trauma center with penetrating neck injuries (gunshot wounds and lacerations) were examined prospectively with color(More)
PURPOSE To show that postgadolinium three-dimensional time-of-flight MR angiography shows abnormal intradural vessels associated with spinal dural arteriovenous fistula better than routine MR imaging and provides screening information useful for subsequent diagnostic conventional angiography and/or posttreatment evaluation. METHODS Precontrast and(More)
We read with interest Luzardo et al’s technical note in the December issue of the AJNR. Although we are pleased that the new Envoy 6F guide catheter (Cordis, Miami Lakes, Fla) facilitated a dualmicrocatheter procedure with a single arterial access, it should be noted that this is by no means a new technique. The 6F Envoy guide catheter with an inner(More)
OBJECTIVES Pseudoaneurysms of the superficial temporal artery present as slowly growing masses of the face or scalp. They may arise as a result of infection or autoimmune disease but most commonly are sequelae of blunt, penetrating, or surgical trauma. We describe their clinical presentation and differential diagnosis and compare several treatment options.(More)
BACKGROUND Acute ischemic stroke diagnosis and treatment are among the most challenging in Emergency Medicine. Perfusion computed tomography (CTP) can increase the sensitivity for detecting ischemic stroke and, especially with the addition of CT angiography (CTA), improve decision-making regarding thrombolytic therapy compared to non-contrast computed(More)
