  2. 1. Cerebrovascular accidents associated with aortic manipulation during cardiac surgery

    Author : Patrik Boivie; Gunnar Engström; Magnus Hansson; Henrik Ahn; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic atherosclerosis; aortic cannulation; aortic cross-clamp; cardiac surgery; cerebral protection; cerebrovascular accidents; epiaortic ultrasound; intra-aortic filter; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Abstract : Background: Despite the successful development in cardiac surgery, cerebrovascular accidents (CVA) remain a devastating complication. Aortic atherosclerosis has been identified as a major risk factor for CVA. READ MORE

  4. 2. Evaluation of a Laser Doppler System for Myocardial Perfusion Monitoring

    Author : Carina Fors; Karin Wårdell; Henrik Casimir Ahn; Maria Lindén; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser Doppler perfusion monitoring; myocardial microcirculation; coronary artery bypass graft; Medical engineering; Medicinsk teknik;

    Abstract : Coronary artery bypass graft (CABG) surgery is a common treatment for patients with coronary artery disease. A potential complication of CABG is myocardial ischemia or infarction. In this thesis, a method - based on laser Doppler flowmetry (LDF) - for detection of intra- and postoperative ischemia by myocardial perfusion monitoring is evaluated. READ MORE

  5. 3. The use of mechanical circulatory support and passive ventricular constraint in patients with acute and chronic heart failure

    Author : Hans Granfeldt; Henrik Ahn; Torbjörn Ivert; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Many patients are diagnosed as having chronic heart failure (CHF) and apart from the fact that daily activities are impaired, they are great consumers of health care, and the prognosis is poor. The distinction between acute heart failure (AHF) and CHF may be difficult and is more a question of time rather than severity. READ MORE

  6. 4. Quantitative diffuse reflectance spectroscopy : myocardial oxygen transport from vessel to mitochondria

    Author : Tobias Lindbergh; Tomas Strömberg; Henrik Ahn; Marcus Larsson; Lise Lyngsnes Randeberg; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction.

  7. 5. Management of patients treated with left ventricular assist devices : A clinical and experimental study

    Author : Bengt Peterzén; Henrik Casimir-Ahn; Hans Ruthberg; Lars Wiklund; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postcardiotomy heart failure; perioperative monitoring; coronary artery bypass; heart-assist devices; heart failure; congestive; ventricular dysfunction; Thoracic surgery; Thoraxkirurgi;

    Abstract : This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. READ MORE
