Zusammenfassung:The funnel technique, the hybrid assembly of a thoracic and abdominal aortic endograft, is advantageous for frail patients where efficient oversizing is not possible for infrarenal wide aortic necks over 34 mm. We sought to determine the advantages and disadvantages of the Funnel-endovascular aneurysm repair (EVAR) technique using 60 mm length thoracic endograft. This retrospective study included 22 patients, all frail with high comorbidities, who were operated on with the Funnel technique using the 60 mm Lifetech Ankura thoracic endograft, in 7 urgent and 15 elective cases from January 2018. There were no exclusion criteria except having an age 60 years. Primary endpoints were the technical success and early mortality and morbidity; secondary endpoints were late outcomes such as endoleak, migration, late open surgical conversion, successful sac shrinkage, and enlargement at the infrarenal aortic neck diameter. The patients' mean age was 72.6 7.3 years (62-86 years), with a mean aneurysm diameter of 83.2 16.8 mm and mean infrarenal aortic diameter of 38.7 2.4 mm. There was no early mortality. Technical success was 100%. 21 standard bifurcated and one aorto-uni-iliac abdominal endograft were deployed. The mean fluoroscopy time was 14.3 5.2 minutes. Mean follow-up was 32.8 19.6 months, with no endovascular complications. There was no Type-1a or Type-3 endoleak, migration, infrarenal aortic neck diameter enlargement, or aneurysm sac enlargement. During the follow-up, three patients died, but there was no aneurysm-related mortality. Funnel-EVAR is effective and safe for patients with a wide infrarenal aortic neck diameter when assessing midterm outcomes. Therefore, it should be part of the armamentarium of a vascular surgeon in patients with wide aortic necks 34 mm.
