1. Physiological and pathophysiological cerebrovascular regulation monitored by transcranial doppler
Abstract : Transcranial Doppler ultrasonography (TCD) became available in the middle of the 1980s as a new technique for examining cerebral circulation. With this technique it is possible to measure the velocity of blood flow in major cerebral arteries. READ MORE

2. Cardiac surgery and the brain - studies on cerebral blood flow autoregulation and mechanisms of cerebral injury
Abstract : Cardiac surgery and the brain - studies on cerebral blood flow autoregulation and mechanisms of cerebral injury Björn Reinsfelt Department of Anaesthesiology and Intensive Care, Institute of Clinical Sciences, The Sahlgrenska Academy, University of Gothenburg, Sweden Abstract Cerebral dysfunction (CD) occurs frequently after cardiac surgery with cardiopulmonary bypass (CPB). The main causes of CD are thought to be cerebral hypoperfusion, cerebral microembolisation , cerebral inflammation or disruption of the blood brain barrier (BBB). READ MORE

3. New Intraoperative Techniques to Improve Advanced Aortic Root Surgery
Abstract : Study I: Thirteen patients underwent a modified Ross operation in which the free-standing pulmonary autograft was supported externally by a Dacron vascular prosthetic jacket (DVPJ). The tailor-made DVPJ prevented dilatation of the neo-aortic root significantly following a median follow-up of 47 months compared to a cohort of l3 matched patients undergoing conventional Ross operation.

4. Lund Concept for De-airing of the Left Heart. Clinical Evaluation
Abstract : Background: Residual air accumulated air in the pulmonary veins constitutes a challenge to achievment of complete de-airing in open left heart surgery. To adress this problem, a conceptual method for de-airing was developed in Lund comprising bilateral opening of the pleurae to induce pulmonary collapse and a strategy with gradual pulmonary reperfusion and ventilation at weaning from cardiopulmonary bypass (CPB).

5. Ultrasound Assessment and Vascular Mechanics in Takayasu Arteritis and Systemic Lupus Erythematosus
Abstract : Takayasu arteritis (TAK) and systemic lupus erythematosus (SLE) are inflammatory diseases that primarily affect young women. TAK is a rare vasculitis that affects the aorta and its main branches, whereas SLE is a chronic autoimmune disease that effects multiple organs. READ MORE
