Fellows’ Journal Club February 2015 (1 of 3) Different methods of assessing collateral circulation based on CTA were compared in 200 patients with stroke. Only the Miteff scoring system was reliable for predicting favorable outcome in these patients but poor
Fellows’ Journal Club December 2014 (1 of 3) These authors evaluated CTA studies of 228 patients paying special attention to the clot features, and correlated these features with early reperfusion rates. Clot features that predicted successful early reperfusion included: shorter
Editor’s Choice October 2014 (1 of 3) Safety and efficacy of intra-arterial treatment using the AmplatzGooseNeck device in acute anterior circulation strokes were assessed in 156 patients. High recanalization rates were obtained with the AmplatzGooseNeck snare without any device-related complications.
White matter disease (leukoaraiosis) was long considered a normal occurrence in the aging process. Recent studies, however, have associated leukoaraiosis with dementia and disability, though how and why it develops is still unknown. The authors of a recent paper, funded by an ASNR Scholar Award and published
Fellows’ Journal Club September 2014 (1 of 3) These authors found that increased cerebral blood flow and volume were seen in the basal ganglia of 4.3% of patients with ischemic strokes with CT perfusion. All patients had underlying MCA occlusions,
Editor’s Choice July 2014 (2 of 3) The authors attempted to determine if reperfusion therapy for anterior circulation acute stroke based on MR perfusion resulted in better outcomes at 3 months than that based on noncontrast CT. Perfusion imaging-selected patients

J Neurosurg 2014;121:18–23, 10.3171/2014.3.JNS131493 The authors evaluated 104 patients with 106 aneurysms to define the frequency and types
Fellows’ Journal Club June 2014 (3 of 3) DSA was used to study patients with Moyamoya disease with acute stroke. Advanced Suzuki angiographic stages, aneurysms, arterial occlusions, and collateral flow including transdural anastomoses were present more often in patients with
Fellows’ Journal Club June 2014 (1 of 3) Patients studied for acute stroke were evaluated with full- and half-dose contrast-enhanced neck MRA and brain perfusion imaging and results were compared. Detection specificity and overestimation of stenoses were slightly higher for
Editor’s Choice April 2014 (2 of 3) The presence of poor leptomeningeal collaterals as assessed by CTA was correlated with patient outcome after receiving intra-arterial treatment for stroke. Functional outcomes in 87 patients with MCA and/or ICA occlusions were retrospectively
