OBJECTIVE: This paper aims to evaluate the clinical applyment of "Anatomical fixation" and its long-term efficacy .
METHODS: Retrospective analysis of clinical data and postoperative follow-up results of 125 patients undogoing EVAR using "anatomical fixation" enrolled in Shanghai Changhai hospital and Shanghai Changzheng hospital from January 2008 to January 2013.
RESULTS: The technical success rate was 100%, Perioperative complications including Type I endoleak occurred in 3 patients (2.4%), 4 cases of type II endoleak (3.2%). Incidence of Type I endoleak in challenging neck cases was high than non- challenging neck cases, the difference was statistically significant (P < 0.001). After 30 days and through current follow-up of 124 successful cases(mean:26.4 ± 1.5 months, range 1-60 months). No rupture of the aneurysm and stent graft migrations occurred. Secondary type I endoleak in 2 cases (1.6%), Two cases of secondary type II endoleak (1.6%). Left lower extremity arterial thrombosis in 1 case (0.8%), and secondary surgical intervention in 1 case (0.8%). Three cases of deaths in cumulative, 2 patients died died of acute myocardial infarction. At 3 months, a patient died of the contrast-induced nephropathy, renal failure.
CONCLUSIONS: The clinical applyment of "Anatomical fixation" enriched the theory of EVAR, completely solved the complication of incidence of stent-graft migration, greatly improve the repair rate of hostile neck cases, expand the indications for EVAR.
