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

   Författare :Patrik Boivie; Gunnar Engström; Magnus Hansson; Henrik Ahn; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Minimally invasive aortic valve replacement

   Författare :Magnus Dalén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Minimally invasive aortic valve replacement (AVR) through a ministernotomy has been developed as an alternative approach to conventional full sternotomy AVR. During recent years, sutureless aortic bioprostheses were introduced with the aim to facilitate implantation, especially in minimally invasive procedures. LÄS MER

4. 3. New Intraoperative Techniques to Improve Advanced Aortic Root Surgery

   Författare :Faleh Alrashidi; Thoraxkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Modified Ross Operation; Aortic Root surgery; Microemboli signals MES ; Transcranial Doppler TCD ; Acute plateletphersis APP ; Transesophageal echocardiography TEE ; de-airing;

   Sammanfattning : 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.

5. 4. Stroke during cardiac surgery : risk factors, mechanisms and survival effects

   Författare :Magnus Hedberg; Karl Gunnar Engström; Patrik Boivie; Jan van der Linden; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; cardiac surgery; adult; risk factors; mortality; embolism; aortic cross-clamp; aortic cannulation; Thoracic surgery; Thoraxkirurgi; kirurgi; särskilt thoraxkirurgi; Thoracic and Cardivascular Suregery;

   Sammanfattning : Introduction: Neurological complications and stroke in association with cardiac surgery is a serious problem. The stroke event can occur during surgery (early stroke) or in the postoperative period with a symptom free interval (delayed stroke). LÄS MER

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

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

   Sammanfattning : 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. LÄS MER
