    • 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 ...

    • A fully-coupled fluid-structure interaction simulation of cerebral aneurysms 

      Isaksen, Jørgen Gjernes; Bazilevs, Yuri; Hsu, M. C.; Zhang, Y.; Wang, W.; Liang, X; Kvamsdal, Trond; Brekken, Reidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)

    • Prevalence of unruptured intracranial aneurysms: impact of different definitions-the Tromsø Study 

      Johnsen, Liv-Hege; Herder, Marit; Vangberg, Torgil Riise; Kloster, Roar; Ingebrigtsen, Tor; Isaksen, Jørgen Gjernes; Mathiesen, Ellisiv B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-10)
      Background - Management of incidental unruptured intracranial aneurysms (UIAs) remains challenging and depends on their risk of rupture, estimated from the assumed prevalence of aneurysms and the incidence of aneurysmal subarachnoid haemorrhage. Reported prevalence varies, and consistent criteria for definition of UIAs are lacking. We aimed to study the prevalence of UIAs in a general population ...

    • Prompt closure versus gradual weaning of external ventricular drainage for hydrocephalus following aneurysmal subarachnoid haemorrhage: Protocol for the DRAIN randomised clinical trial 

      Capion, Tenna; Lilja-Cyron, Alexander; Olsen, Markus Harboe; Juhler, Marianne; Moeller, Kirsten; Sorteberg, Angelika; Rønning, Pål Andre; Poulsen, Frantz Rom; Wismann, Joakim; Ravlo, Celina; Isaksen, Jørgen Gjernes; Lindschou, Jane; Gluud, Christian; Mathiesen, Tiit (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-10)
      Background: Aneurysmal subarachnoid haemorrhage (aSAH) is a life-threatening disease caused by rupture of an intracranial aneurysm. A common complication following aSAH is hydrocephalus, for which placement of an external ventricular drain (EVD) is an important first-line treatment. Once the patient is clinically stable, the EVD is either removed or replaced by a ventriculoperitoneal shunt. The ...

    • Survey of European neurosurgeons’ management of unruptured intracranial aneurysms: inconsistent practice and organization 

      Skodvin, Torbjørn Øygard; Kloster, Roar; Sorteberg, Wilhelm; Isaksen, Jørgen Gjernes (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-01)
      Background - The discovery of an unruptured intracranial aneurysm creates a dilemma between observation and treatment. Neurosurgeons’ routines for risk assessment and treatment decision-making are unknown. The position of evidence-based medicine in European neurosurgery is considered to be weak, high-grade guidelines do not exist and variations between institutions are probable. We aimed to explore ...
