Continuous Local Intra-Arterial Nimodipine for the Treatment of Cerebral Vasospasm
Logallo, Nicola; Bøthun, Marianne Lundervik; Guttormsen, Anne Berit; Holmaas, Gunhild; Kråkenes, Jostein; Thomassen, Lars; Svendsen, Frode; Helland, Christian Andre (Peer reviewed; Journal article, 2015)Vasospasm (VSP) is one of the major causes for prolonged neurologic deficit in patients with aneurysmal subarachnoid hemorrhage. Few case series have reported about continuous local intra-arterial nimodipine administration ... -
Dyslipidemia and rupture risk of intracranial aneurysms—a systematic review
Løvik, Katja; Laupsa-Borge, Johnny; Logallo, Nicola; Helland, Christian Andre (Journal article; Peer reviewed, 2021)Dyslipidemia is a well-established risk factor for coronary artery disease. However, the effect on cerebral artery disease, and more specifically the rupture risk of intracranial aneurysms, is unclear and has not yet been ... -
Impaired cerebrovascular reactivity may predict delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage
Bøthun, Marianne Lundervik; Haaland, Øystein Ariansen; Moen, Gunnar; Logallo, Nicola; Svendsen, Frode; Thomassen, Lars; Helland, Christian Andre (Peer reviewed; Journal article, 2019)Introduction: Delayed cerebral ischemia (DCI) is a major cause of disability and death after aneurysmal subarachnoid hemorrhage. The literature suggests that impaired cerebrovascular reactivity (CVR) may be a predictor for ... -
Microarray-based gene expression profiling and DNA copy number variation analysis of temporal fossa arachnoid cysts
Aarhus, Mads; Helland, Christian Andre; Lund-Johansen, Morten; Wester, Knut; Knappskog, Per (Peer reviewed; Journal article, 2010-02-26)Background Intracranial arachnoid cysts (AC) are membranous sacs filled with CSF-like fluid that are commonly found in the temporal fossa. The majority of ACs are congenital. Typical symptoms are headache, dizziness, and ... -
Protein profiling reveals inter-individual protein homogeneity of arachnoid cyst fluid and high qualitative similarity to cerebrospinal fluid
Berle, Magnus; Kroksveen, Ann Cathrine; Haaland, Øystein; Aye, Thin T.; Opsahl, Jill Anette; Oveland, Eystein; Wester, Knut; Ulvik, Rune Johan; Helland, Christian Andre; Berven, Frode S. (Peer reviewed; Journal article, 2011-05-20)Background: The mechanisms behind formation and filling of intracranial arachnoid cysts (AC) are poorly understood. The aim of this study was to evaluate AC fluid by proteomics to gain further knowledge about ACs. Two goals ... -
Quantitative proteomics comparison of arachnoid cyst fluid and cerebrospinal fluid collected perioperatively from arachnoid cyst patients
Berle, Magnus; Kroksveen, Ann Cathrine; Garberg, Hilde Kristin; Aarhus, Mads; Haaland, Øystein; Wester, Knut; Ulvik, Rune Johan; Helland, Christian Andre; Berven, Frode S. (Peer reviewed; Journal article, 2013-04-29)Background: There is little knowledge concerning the content and the mechanisms of filling of arachnoid cysts. The aim of this study was to compare the protein content of arachnoid cysts and cerebrospinal fluid by quantitative ... -
Time course of cerebrovascular reactivity in patients treated for unruptured intracranial aneurysms: A one-year transcranial Doppler and acetazolamide follow-up study
Bøthun, Marianne Lundervik; Haaland, Øystein Ariansen; Logallo, Nicola; Svendsen, Frode; Thomassen, Lars; Helland, Christian Andre (Peer reviewed; Journal article, 2018-04-26)Background. Cerebrovascular reactivity (CVR) is ofen impaired in the early phase afer aneurysmal subarachnoid hemorrhage. Tere is, however, little knowledge about the time course of CVR in patients treated for unruptured ...
