Cerebral aneurysm morphology before and after rupture: nation-wide case series of 29 aneurysms
Skodvin, Torbjørn Øygard; Johnsen, Liv-Hege; Gjertsen, Øivind; Isaksen, Jørgen Gjernes; Sorteberg, Angelika (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-06)<p><i>Background and Purpose</i>: Using postrupture morphology to predict rupture risk of an intracranial aneurysm may be inaccurate because of possible morphological changes at or around the time of rupture. The present study aims at comparing morphology from angiograms obtained prior to and just after rupture and to evaluate whether postrupture morphology is an adequate surrogate for rupture ... -
Fat in the lumbar multifidus muscles - predictive value and change following disc prosthesis surgery and multidisciplinary rehabilitation in patients with chronic low back pain and degenerative disc: 2-year follow-up of a randomized trial
Storheim, Kjersti; Berg, Linda; Hellum, Christian; Gjertsen, Øivind; Neckelmann, Gesche F; Espeland, Ansgar; Keller, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-04)Background: <br> Evidence is lacking on whether fat infiltration in the multifidus muscles affects outcomes after total disc replacement (TDR) surgery and if it develops after surgery. The aims of this study were 1) to investigate whether pre-treatment multifidus muscle fat infiltration predicts outcome 2 years after treatment with TDR surgery or multidisciplinary rehabilitation, and 2) to compare ... -
