  2. 1. Clinical Aspects on Chimney Stent Graft Technique in Endovascular Repair of the Aorta

    Author : Adel BinJabr; Vaskulära sjukdomar - kliniska studier; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chimney stent graft; chimney graft; chimney graft technique; snorkel technique; endovascular aortic repair; thoracic endovascular aortic repair; endoleak; patency; rupture; urgent; stent-graft; stent; graft; aorta; computed tomography; ultrasound; stenosis; EVAR; TEVAR; CTA; MRI; AAA; TAAA; supraaortic; visceral; aneurysm; dissection; mycotic infection; stent-graft infection; follow-up; endovascular complication; sandwich technique; periscope graft; periscope graft technique.;

    Abstract : Introduction: Open repair of the aorta carries a high risk for morbidity and mortality especially in the elderly population and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. READ MORE

  4. 2. Interventions for portal hypertension in patients with portal vein occlusion and possible effects of a stent-graft on hepatic circulation

    Author : Inger Keussen; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; recanalization; TIPS; hepatic vein occlusion; children; Key words: portal vein occlusion; scintigraphy; stent; portal hypertension;

    Abstract : Symptomatic portal hypertension (PH), is often treated by transjugular intrahepatic portosystemic shunt (TIPS). Patients with PH, caused by prehepatic portal vein occlusion, require recanalization with stent or stent-graft often followed by additional TIPS. READ MORE

  5. 3. Experimental studies on thrombin inhibition in acute- and chronic models of vessel wall injury

    Author : Fredrik Scherstén; Göteborgs universitet; []
    Keywords : animal model; antithrombin; fibrinogen; histomorphology; melagatran; percutaneous coronary intervention; platelets; restenosis; stent; thrombin inhibition; thrombosis;

    Abstract : Background: The number of percutaneous coronary interventions (PCI) performed worldwide has increased dramatically during the last decade. Complication rates have decreased over time, however the restenosis phenomenon remains an unsolved issue. Thrombin is the key regulator in the pro-coagulant state following PCI. READ MORE

  6. 4. MRI with MR Angiography in Endovascular Repair of Abdominal Aortic Aneurysms

    Author : Lena Engellau; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; radiology; Clinical physics; Contrast media complications; Cost analysis; MR velocity mapping; Artefacts; MR imaging safety; MR angiography; MR imaging; Endovascular repair; Stent-graft; aortic; Aneurysm;

    Abstract : The aim of this study was to evaluate MRI with contrast enhanced MR angiography (MRI/CE MRA) as imaging method before and after endovascular repair of abdominal aortic aneurysms (AAA). A 1.5 T scanner was used for all examinations. In this prospective study 26 consecutive patients were included. READ MORE

  7. 5. Re-interventions after endovascular aortic repair: clinical and experimental studies

    Author : Håkan Roos; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EVAR; stent graft; blood flow; displacement forces; aortic aneurysm; angulation; reoperation;

    Abstract : Background: Endovascular aortic repair (EVAR) has lower morbidity and mortality than open surgery. Late complications and re-interventions are more common, however, and the timing of different re-interventions and their respective underlying causes are not fully understood. READ MORE
