1. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis
Sammanfattning : Blood flow measurements are important for understanding the development of cerebrovascular diseases. With 4D flow magnetic resonance imaging (4D flow MRI), simultaneous velocity measurements are obtained in all cerebral arteries in a scan of about ten minutes. However, 4D flow MRI is a relatively new technique. LÄS MER
2. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging
Sammanfattning : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.

3. Cardiovascular risk factors and peripheral vascular function in lung transplant recipients
Sammanfattning : Objective: Cardiovascular disease is a major contributor to morbidity and mortality after organ transplantation. Development of cardiovascular risk factors, like hypertension, is common after transplantation. LÄS MER
4. Prevention of surgical site infections after lower extremity bypass procedures
Sammanfattning : Abstract: Surgical site infections (SSIs) are a common cause of morbidity following open vascular surgery. Numerous randomized controlled trials (RCTs), along with systematic reviews and meta-analyses of RCTs, have been conducted to compare incisional negative pressure wound therapy (iNPWT) with standard wound dressings above sutured incisions in the inguinal region.

5. Cerebral blood flow and intracranial pulsatility studied with MRI : measurement, physiological and pathophysiological aspects
Sammanfattning : During each cardiac cycle pulsatile arterial blood inflates the vascular bed of the brain, forcing cerebrospinal fluid (CSF) and venous blood out of the cranium. Excessive arterial pulsatility may be part of a harmful mechanism causing cognitive decline among elderly. LÄS MER
