  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. Spinal cord ischemia : An experimental study of the spinal cord blood supply and peroperative ischemia detection by a new method of intrathecal monitoring

    Author : Lennart Christiansson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Spinal cord ischemia; Oxygen tension; Intrathecal monitoring; Ultrastructure; Aortic cross-clamping; Thoracoabdominal aneurysm; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

    Abstract : Spinal cord ischemia associated with thoracoabdominal aortic surgery may lead to devastating neurological complications. Improvement in bypass techniques and various adjunctive measures has reduced its incidence, but still 5-10 % of the patients develop postoperative paraplegia. READ MORE

  5. 3. On intestinal ischaemia after aortoiliac surgery : Epidemiological, clinical and experimental studies

    Author : Martin Björck; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Ischaemia; intestines; colon; ischaemic colitis; aorta-abdominal; aortic aneurysm-abdominal; aortic rupture; atherosclerosis; postoperative complications; cohort studies; case-control studies; clinical protocols; experimental design; incidence; risk factors; diagnosis; treatment outcome; intra-mucosal pH; pHi; swine; splanchnic circulation; haemodynamics; dobutamine; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : An important cause of death among patients undergoing surgery of the abdominal aorta is intestinal ischaemia. In the Swedish Vascular Registry 2930 aortoiliac operations were identified. The complication was studied in a combined cohort and case-control study, and multivariate analysis performed. The incidence of intestinal ischaemia was 2. READ MORE

  6. 4. Management of thoracoabdominal aortic aneurysms and dissections : with emphasis on spinal cord protection in aneurysm repair and non-surgical treatment of type-B dissection

    Author : Anders Winnerkvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Aortic cross-clamping; cerebrospinal fluid drainage; GFAp; NFL; retrograde venous spinal cord perfusion; somatosensory evoked potentials; S100B; thoracoabdominal aortic aneurysm; type B aortic dissection.;

    Abstract : Thoraco-abdominal aortic aneurysms and dissections are two very serious disease processes which entail a high risk of vessel rupture and death. Their specific treatment strategies have several similarities which have formed a base for this thesis. READ MORE

  7. 5. Hemodynamic and cardiometabolic studies in patients with distributive circulatory dysfunctions : with special reference to the effects of the beta-1-adrenoreceptor agonist prenalterol

    Author : Sebastian Reiz; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic aneurysm surgery; gram negative septic shock; hemodynamics; myocardial metabolism; thermodilution; thoracic epidural block; volume loading; prenalterol;

    Abstract : A total of 49 patients were studied, using invasive hemodynamic techniques with systemic arterial, pulmonary artery and right atrial pressure recordings together with thermodilution cardiac output determinations. Sixteen of the patients were also subjected to cardiometabolic studies, using measurement of coronary sinus blood flow by the continuous thermodilution technique and analyses of oxygen content and lactate concentration in the systemic and coronary circulation.
