2. 1. Pressure autoregulation of cerebral blood flow in traumatic brain injury and aneurysmal subarachnoid hemorrhage

   Author : Ulf Johnson; Per Enblad; Lars-Owe Koskinen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral blood flow; autoregulation; traumatic brain injury; subarachnoid hemorrhage; Neurosurgery; Neurokirurgi;

   Abstract : The ability of the brain to keep a stable and adequate cerebral blood flow (CBF) independently of fluctuations in systemic blood pressure is referred to as cerebral pressure autoregulation (CPA). When the brain is injured by trauma or hemorrhage, this ability may be impaired, leaving the brain vulnerable to events of high or low blood pressure. READ MORE

4. 2. Pituitary dysfunction and relation to cognitive and global outcome after traumatic brain injury or aneurysmal subarachnoid haemorrhage

   Author : Anna Tölli; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Traumatic brain injury (TBI) and aneurysmal subarachnoid haemorrhage (aSAH) are leading causes of deaths and may cause permanent physical, cognitive, behavioural, and psychosocial disabilities limiting daily activities in survivors. One potential complication of TBI and aSAH is deficient secretion of one or more pituitary hormones. READ MORE

5. 3. Coping, Psychiatric Morbidity and Perceived Care in Patients with Aneurysmal Subarachnoid Haemorrhage

   Author : Mathilde Hedlund; Lisa Ekselius; Marianne Carlsson; Elisabeth Ronne-Engström; Jerker Hetta; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subarachnoid haemorrhage; health related quality of life; depression; nursing care; post traumatic stress disorder; psychiatric disorders; coping; Caring sciences; Vårdvetenskap; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

   Abstract : Many patients with an aneurysmal subarachnoid haemorrhage (SAH) exhibit difficulties in rehabilitation, even in cases of a good prognosis. The present project investigates this using qualitative methods and standardised outcome measures. READ MORE

6. 4. Severe cerebral emergency : aspects of treatment and outcome in the intensive care patient

   Author : Marie Rodling Wahlström; Silvana Naredi; Sven-Erik Gisvold; Umeå universitet; []

   Abstract : Severe Traumatic Brain Injury (TBI) and aneurysmal Subarachnoid Hemorrhage (SAH) are severe cerebral emergencies. They are common reasons for extensive morbidity and mortality in young people and adults in the western world. READ MORE

7. 5. Non-invasive diagnostic methods of intracranial arteries

   Author : Birgitta Ramgren; Lund Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracranial aneurysms; endovascular treatment; follow-up; subarachnoid haemorrhage; digital subtraction angiography; magnetic resonance angiography; computed tomography angiography; technical aspects; contrast agents; image quality;

   Abstract : Aims of this thesis were to compare the agreement of different magnetic resonance angiography(MRA) techniques and digital subtraction angiography (DSA) in follow-up of intracranial aneurysms treated with coils in order to select the best MRA method, to evaluate the impact of increased iodine concentration in contrast medium and decreased tube voltage on arterial attenuation and image quality in computed tomography angiography (CTA) of intracranial arteries, and finally to evaluate the diagnostic accuracy of CTA in non-traumatic subarachnoid haemorrhage (SAH) compared to DSA and to assess the arterial attenuation (HU) as an image quality factor in this aspect. Follow-up DSA and time-of-flight (TOF) MRA at 1. READ MORE
