Netteland D, Aarhus M, Sandset E, Sorteberg A, Padayachy L, Helseth E, et al.
Neurocrit Care . 2025 Jan; PMID: 39776344
Background: Optic nerve sheath diameter (ONSD) is a promising noninvasive parameter for intracranial pressure (ICP) assessment. However, in the setting of aneurysmal subarachnoid hemorrhage (aSAH), several previous studies have reported...

Emendi M, Tangen G, Di Giovanni P, Ulsaker H, Brekken R, Manstad-Hulaas F, et al.
Int J Comput Assist Radiol Surg . 2024 Jun; 19(11):2239-2247. PMID: 38824470
Purpose: Currently, the intra-operative visualization of vessels during endovascular aneurysm repair (EVAR) relies on contrast-based imaging modalities. Moreover, traditional image fusion techniques lack a continuous and automatic update of the...

Scand Cardiovasc J . 2024 Apr; 58(1):2335906. PMID: 38613333
: The multibranched off-the-shelf Zenith® t-Branch (Cook Medical, Bloomington, IN) device is commonly chosen for endovascular repair of thoracoabdominal aortic aneurysms. The aim of this study was to report early...

Brekken R, Hofstad E, Solberg O, Tangen G, Leira H, Gruionu L, et al.
Med Eng Phys . 2024 Mar; 125:104116. PMID: 38508792
The purpose of this study was to evaluate the accuracy of a method for estimating the tip position of a fiber optic shape-sensing (FOSS) integrated instrument being inserted through a...

Netteland D, Aarhus M, Sandset E, Padayachy L, Helseth E, Brekken R
Neurocrit Care . 2024 Mar; 41(2):479-488. PMID: 38448744
Background: Today, invasive intracranial pressure (ICP) measurement remains the standard, but its invasiveness limits availability. Here, we evaluate a novel ultrasound-based optic nerve sheath parameter called the deformability index (DI)...

Front Radiol . 2024 Feb; 4:1320535. PMID: 38333532
Electromagnetic tracking of instruments combined with preoperative images can supplement fluoroscopy for guiding endovascular aortic repair (EVAR). The aim of this study was to evaluate the in-vivo accuracy of a...

Netteland D, Aarhus M, Smistad E, Sandset E, Padayachy L, Helseth E, et al.
Front Neurol . 2023 Feb; 14:1064492. PMID: 36816558
Introduction: Optic nerve sheath diameter (ONSD) has shown promise as a noninvasive parameter for estimating intracranial pressure (ICP). In this study, we evaluated a novel automated method of measuring the...

J Endovasc Ther . 2022 Sep; 31(2):312-317. PMID: 36121010
Purpose: Cannulation of visceral vessels is necessary during fenestrated and branched endovascular aortic repair. In an attempt to reduce the associated radiation and contrast dose, an electromagnetically (EM) trackable and...
