Possibilities and limitations in the endovascular repair of abdominal aortic aneurysm
Journal Title: Postępy Nauk Medycznych - Year 2012, Vol 25, Issue 8
Abstract
The abdominal aortic aneurysm (AAA) is the cause of 1 to 3% of deaths among males in the age between 65 and 85 years. Within the last twenty years, increased incidence of aneurysms was recorded, which may be associated with population aging, and increasing number of smokers, but also with introduction of screening programs and constant modernization of diagnostic methods. Patients with asymptomatic AAA measuring at least 55 mm in diameter are classified to elective surgery in order to reduce the risk of aneurysm rupture. Two treatment methods are available: an open laparotomy and implantation of an internal prosthesis (so-called stent graft) through the femoral artery approach without opening the abdominal cavity. Stent graft is implanted with the endovascular method (EVAR). Purpose of this study is to select treatment methods, and qualification for the open laparotomy or endovascular treatment of the abdominal aortic aneurysms. Comparing to standard surgery, there is two- to three-fold reduction of 30-day postoperative mortality in the elective endovascular treatment. EVAR, comparing to the classic surgery, is a minimally invasive procedure involving the introduction of a special endovascular prosthesis (stent graft) into the aneurysm cavity through the femoral artery approach. Even if EVAR is associated with higher rates of late repeated interventions, it is more willingly accepted by the patients. Endovascular aortic repair becomes the method of choice.
