OBJECTIVE: To evaluate the clinical outcomes of unibody bifurcated stent-graft in endovascular repair (EVAR).
METHODS: Retrospective analyses were conducted for the clinical data and postoperative follow-up results of 125 patients (102 cases from Shanghai Changhai Hospital and another 23 from Shanghai Changzheng Hospital) undergoing EVAR with unibody bifurcated stent-graft from January 2008 to January 2013.
RESULTS: The technical success rate was 100%. Perioperative complications including type I endoleak (n = 3, 2.4%) and type II endoleak (n = 4, 3.2%). The incidence of type I endoleak in challenging neck cases was higher than non-challenging ones. And the difference was statistically significant (P = 0.001). Except for 1 dead case, the remainder was followed up for a mean of 26.4 ± 1.5 (1-60) months. Neither aneurysm rupture nor stent-graft migration occurred. Late type I endoleak occurred (n = 2, 1.6%). There were left lower extremity arterial thrombosis (n = 1, 0.8%) and surgical reintervention (n = 1, 0.8%). Among 3 dead cases, 2 died from acute myocardial infarction and another 1 contrast-induced nephropathy.
CONCLUSION: Unibody bifurcated stent-graft is both safe and efficacious in the treatment of abdominal aortic aneurysm without the risk of long-term migration. Moreover, it has excellent outcomes for hostile neck or narrow abdominal aortic bifurcation.
