Retrospective Analysis Research Between Endovascular Repair And Open Surgery In Abdominal Aortic Aneurysm Patients

To compare endovascular repair and open surgery in patients with abdominal aortic aneurysms (AAAs). Methods All consecutive conscious patients with AAAs who presented to PUMC hospital between January1,2000and January1,2010were included in this study (n=92).After that25patients by open surgery and28patients by endovascular repair were followed-up successfully. Outcomes evaluated preoperative, perio-perative, mortality, systemic complications. The statistical tests were the Student t test and non-parameter test. Results With the elder patients (73vs65), endovascular repair had shown us that reducing operation time by50%, less bleeding and less blood transfusion or even none about blood, and no less but decrease in degree in systemic complications, and less opportunity to get into the ICU, only with the3times cost by the expensive materials to the traditional open surgery. Endovascular repair also improved the asymptomatic survival time from30days after the surgery to the longest8years (P<0.01). But to the overall mortality and AAAs related mortality, EVAR only showed the advantage in the1st and2nd year. Conclusions In our highly selected population, EVAR is better only for the early period result than the open surgery and for the advantage in safety and less trauma but with much more cost.
