Curative Effects And Complications Of Endovascular Aneurysm Repair For Infrarenal Abdominal Aortic Aneurysm With New Stent-graft EXCLUDER And ENDURANT

Objective: To evaluate the clinical curative effects and thecomplications of endocascular aneurysm repair(EVAR) forinfrarenal abdominal aortic aneurysm with new stent-graftEXCLUDER and ENDURANT.Methods: Between March2010and October2013，the42patients(42Lesions) with infrarenal abdominal aortic aneurysm weretreated with endovascular aortic repair(EVAR) in department ofinterventional radiology of the Union Hospital of FujianMedical University. Customized stent-grafts(SG) wereEXCLUDER and ENDURANT．All of the patients were followed upwith ultrasonography or enhanced computed tomography every3months first year after EVAR and every year after.Results: ALL the42cases were confirmed by CTA before EVAR.Two were ruptured cases and EVAR performed by emergency.Primary technical success rate was100％．No patient died during the perioperative period．Four experienced primary endoleakwhich were disappeared in a month without any medical interfere.One case of type Ⅲ endoleak was observed and cured by applyinga new SG. Fourteen cases experience post-implantation syndrome(PIS) which cured by symptomatic treatment. One case sufferedfrom cerebral infarction soon after the EVAR. Two cases of SGinfection were observed, one was treated by anti-infectivetherapy. However, the other one shows the infective lesion wasprogressive and caused the patient’s death. The diameter ofthe AAA shows significant shink(P＜0.05),while the length ofthe AAA neck shows no significant changes during the follow-upperiod(P＞0.05). The mid-term complications were observedincluding two of lower limb weakness. No endoleak or SGmigration were observed during the follow-up period．Conclution:1. EVAR is feasible with less trauma，quick recoveryand less complications and may be offered as the best means oftherapy in patients suffered from infrarenal abdominal aorticaneurysm．2. The new stent-graft ENDURANT and EXCLUDER, withits barbed structure, which can reduce the complicationssignificantly such as endoleak and SG migration.3. Endoleak isthe most common complication after EVAR and can be treatedwith balloon expansion or implanting a new SG.4. Is the use of antibiotics associated with the occurrence of PIS need tobe further confirmed.5. The long-term curative effect of EVARneed to be further confirmed.
