- Deep brain stimulation (DBS) of the nucleus ventralis intermedius thalami (Vim) in the treatment of essential tremor (ET) is well documented concerning the acute effects. Reports of the long-term effects are, however, few and the aim of the present study was to analyse the long-term efficacy of this treatment. Nineteen patients operated with unilateral Vim-DBS were evaluated with the Essential Tremor Rating Scale (ETRS) before surgery, and after a mean time of 1 and 7 years after surgery. The ETRS score for tremor of the contralateral hand was reduced from 6.8 at baseline to 1.2 and 2.7, respectively, on stimulation at follow-up. For hand function (item 11 – 14) the score was reduced from 12.7 to 4.1 and 8.2, respectively. Vim-DBS is an efficient treatment for ET, also after many years of treatment. There is, however, a decreasing effect over time, most noticeable concerning tremor of action. Read More: http://informahealthcare.com/doi/abs/10.1080/02688690701552278

- Combining previously independently established techniques our objective was to develop and evaluate a method for bedside qualitative assessment of cerebral blood flow in neurointensive care (NICU) patients. The CT-protocol was optimized using phantoms and comparing a mobile CT-scanner (Tomoscan-M, Philips) with two stationary CT scanners. Thirty-two per cent xenon was delivered with standard equipment (Enhancer 3000). Mean cortical flow in volunteers was 48 ml/min/100 g, with the mean vascular territorial flow varying between 45 and 66 ml/min/100 g. The potential clinical usefulness was illustrated in three patients with vasospasm following subarachnoid haemorrhage. Our conclusion is that quantitative bedside measurements of CBF can be repeatedly performed in an easy and safe way in a standard NICU-setting, using xenon-inhalation and a mobile CT-scanner. The method is useful for the decision-making, and is a good example of how the quality of multi-modality monitoring in the NICU can be developed and further diversified. © The Neurosurgical Foundation.

- Cerebral vasospasm is the major cause of delayed ischemia in patients with subarachnoid haemorrhage (SAH). The Fisher grading scale has been used to predict patients in risk of developing vasospasm. Improved radiological techniques and treatment may have changed the relevance of the Fisher scale. We have now evaluated the Fisher scale, Hunt and Hess and age in relation to outcome in patients with SAH. Eighty- three patients were admitted with SAH during two years, and 84 aneurysms were treated in 78 patients. The Glasgow outcome score (GOS) within 3 months were as follows; GOS 1 (19%), GOS 2 (2%), GOS 3 (11%), GOS 4 (9%), GOS 5 (59%). There was a significant correlation between both the Fisher grading scale, Hunt and Hess scale and outcome. Age was not correlated to the Fisher grading scale or the Hunt and Hess scale. Age was also not correlated to outcome in our patients. Despite the correlation to outcome both Hunt and Hess and the Fisher grading scale had a limited predictive value of outcome due to a low specificity and/or sensitivity.

Tidskriftsartikel (refereegranskat)abstract
- In this study we present the population-based patient material with spontaneous SAH, treated in our Neurosurgical unit during the 10 years (1997-2006) after the introduction of endovascular treatment of aneurysms (EVT) in our hospital. All patients that had a spontaneous SAH and a potential to survive were admitted. The present study comprises 1471 patients. 72 % had one or more aneurysms. AVM or other vascular pathological findings where found in 2%. Angiography was judged as normal in 21% and was not performed in 5%. 664 of the patients with aneurysms were treated by endovascular means, 333 were operated and 31 were treated with both methods. Thirty-five received no treatment. The main difference in admission parameters between the coiled and clipped aneurysms was the location of the aneurysm, with posterior circulation aneurysm exclusively being coiled and MCA aneurysms mainly clipped. The highest 6-month mortality for aneurysms presented in the untreated group (71.4%), and the lowest (3.2%) in the group treated with both clip and coil. Six-month mortality was 3.5% for the patients with a normal angiography. Of these, no one with Fisher grade 1 and 2/120 patients with Fisher 2 died. The mortality was high (89%) for those patients where angiography was not performed. The present patient group was compared to an earlier published a 12-year patient series from our clinic. The patients with aneurysmal SAH in the present series were older and had a lower 6-month mortality in our material compared to the published data from our clinic from 1981-1992. More patients were admitted in a good clinical condition in the present series, but there was also a higher proportion of patients from the worst clinical groups. The percentage of aneurysms treated had increased from 80% to 97% after EVT was introduced.

Potential use of quantitative bedside CBF monitoring (Xe-CT) for decision making in neurosurgical intensive care

Tidskriftsartikel (refereegranskat)abstract
- During a 3-year period, mobile xenon-computerized tomography (Xe-CT) for bedside quantitative assessment of cerebral blood flow was used as an integrated tool for decision making during the care of complicated patients in our neurosurgical intensive care units (NSICU), in an attempt to make a preliminary evaluation regarding the usefulness of this method in routine work in the neurosurgical intensive care. With approximately 200 studies involving 75 patients, we identified six different categories where the use of bedside Xe-CT significantly influenced (or, with more experience, could have influenced) the decision making, or facilitated the handling of patients. These categories included identification of problems not apparent from other types of monitoring, avoidance of adverse effects from treatment, titration of standard treatments, evaluation of the vascular resistance reserve, assessment of adequate perfusion pressure and better utilization of resources from access to the bedside cerebral blood flow (CBF) technology. We conclude that quantitative bedside measurements of CBF could be an important addition to the diagnostic and monitoring arsenal of NSICU-tools. © The Neurosurgical Foundation.
