摘要
BACKGROUND: To assess immediate and midterm outcomes of hemodynamically-unstable patients with ruptured abdominal aortic aneurysm (rAAA) treated with the Nellix endovascular sealing system (EVAS). METHODS: From June 2014 to June 2017, 21 hemodynamically-unstable rAAA patients with challenging anatomies were treated with EVAS. The mean AAA diameter and neck length measured 73 +/- 15 mm and 14 +/- 10 mm, respectively. All the patients presented an advance trauma life support (ATLS) hemorrhage class >= 1 confirming a compromised hemodynamic status. Primary endpoints include technical success, treatment success, primary safety and 30-day survival. Secondary endpoints include re-intervention rate and time free-from-reintervention. RESULTS: Technical success was achieved in 95% (N.=20/21); one patient was converted intraoperatively to open surgery due to ongoing hemorrhage. Seven re-interventions were performed within 30-days and one during the follow-up; treatment success rate of67% and re-intervention rate of 33%. Early endoleaks were diagnosed in 5 patients (24%). Primary safety was 52%. After a mean follow-up of 11 +/- 10 months, survival rates were 81%, 62% and 57% at 1, 6 and 12 months, respectively. Time free-from-reintervention was 15 +/- 11 months. CONCLUSIONS: Emergency-EVAS (eEVAS) appeared feasible and useful, especially in hemodynamically-unstable patients with challenging anatomies. There are some limitations in this cohort study and larger, prospective and comparative studies are required to confirm eEVAS as part of an emergency treatment protocol for rAAA.
