AB  - BACKGROUND: Type 2 endoleaks (T2Es) are the main cause of reintervention after 
      endovascular repair of abdominal aortic aneurysms (EVAR). The objective of this 
      study is to quantify success rates of T2E treatment. METHODS: This study involves 
      a retrospective analysis of a prospectively maintained database containing data 
      on all consecutive patients treated for a T2E between 2003 and 2017 in a single 
      center. Technical success was defined as absence of endoleak in the final 
      angiographic control after treatment. Clinical success was defined as absence of 
      sac growth over 5 mm in the contrast-enhanced computed tomography performed a 
      year thereafter. Statistics included Kaplan-Meier survival estimates. RESULTS: A 
      total of 528 elective EVARs were performed in the period. Thirty-six of these 
      (6.8%) developed a T2E requiring reintervention, a median of 37.9 months after 
      EVAR. Twenty-five percent of the treatments were performed more than 5 years 
      after intervention. Twenty-eight of the 36 treatments were performed via 
      transarterial embolization. For this technique, technical success was 71.4% and 
      clinical success was 62.5%. A subsequent reintervention was required in 35.7% of 
      patients. In this cohort, the rate of aneurysm rupture was 10.7% (n = 3/28), open 
      surgical conversion was needed in 2 of 28 cases (7.1%), and rate of 
      aneurysm-related death was 14.3% (n = 4/28) over follow-up. CONCLUSIONS: A high 
      percentage of patients are at risk of adverse outcomes after T2E treatment. 
      Strict imaging follow-up is still needed in this population.
