  1. 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; 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
