Using Body Mass Index to Predict Needle Length in Fluoroscopy-Guided Lumbar Punctures
A.P. Nayate, I.M. Nasrallah, J.E. Schmitt and S. Mohan

American Journal of Neuroradiology March 2016, 37 (3) 572-578; DOI: https://doi.org/10.3174/ajnr.A4579

The authors evaluated patients who underwent oblique interlaminar-approach fluoroscopy-guided lumbar punctures and had cross-sectional imaging of the lumbar spine within 1 year of the lumbar puncture to devise a formula for the appropriate needle length based on BMI. They determined the formula to predict the needle length as Skin-Canal Distance (inches) = 0.077 x BMI + 0.88.

Flow-Diverter Stents for the Treatment of Saccular Middle Cerebral Artery Bifurcation Aneurysms
J. Caroff, H. Neki, C. Mihalea, F. D'Argento, H. Abdel Khalek, L. Ikka, J. Moret and L. Spelle

American Journal of Neuroradiology February 2016, 37 (2) 279-284; DOI: https://doi.org/10.3174/ajnr.A4540

Fourteen patients with 15 saccular, nondissecting MCA bifurcation aneurysms were treated with flow-diverter stents and were retrospectively analyzed. Procedure-related morbidity and mortality at last follow-up were 21% and 0%, respectively. Complete occlusion was achieved in 62%. The authors conclude that compared with other therapeutic options, flow-diverter stents do not appear to be suitable for the treatment of saccular MCA bifurcation aneurysms.

Carotid Near-Occlusion: A Comprehensive Review, Part 2—Prognosis and Treatment, Pathophysiology, Confusions, and Areas for Improvement
E. Johansson and A.J. Fox

American Journal of Neuroradiology February 2016, 37 (2) 200-204; DOI: https://doi.org/10.3174/ajnr.A4429

Carotid near-occlusion is distal luminal collapse of the internal carotid artery beyond a tight stenosis. Part 2 of this systematic review focuses on prognosis and treatment and pathophysiology. Areas of confusion regarding terminology, diagnosis, and prognosis are also covered.
