| Abstract | Background: The objective of this study was to assess the Altura endoprosthesis outcomes up to 12 months for patients affected by infrarenal abdominal aortic aneurysms (AAA) either in elective or emergent situations. Methods: This was a single-center retrospective study identifying all patients undergoing endovascular aneurysm repair (EVAR) with the Altura endoprosthesis from January 2021 to August 2022. Outcomes evaluated included mortality, technical and clinical success (freedom from procedure-related death, endoleak, migration, thrombosis, and reintervention), and the freedom from reintervention rate. Results: A total of 34 (25 elective and 8 emergent) patients who underwent AAA with Altura endoprosthesis were retrospectively reviewed. The technical success of the Altura endograft either in elective or emergent situations was 100%. There was no inhospital mortality, but 1 (3%) patient who underwent AAA repair emergently, died unexpectedly 7 days after the discharge due to massive pulmonary embolism. The clinical success and the freedom from reintervention during the median follow-up of 12 months (interquartile range [IQR] 12-18), were 97%. One patient presented with disabling intermittent claudication at third month postoperatively, and the computed tomographic angiography (CTA) revealed thrombosis of one of the iliac endografts (3%). The patient underwent femorofemoral bypass with an uneventful postoperative course and immediate relief of the symptoms. One type II endoleak was spontaneously resolved on the sixth month. Sac shrinkage (>3 mm) was registered in 12 patients (35%), but the sac size was stable in the remaining 22 (65%) patients. Conclusions: The preliminary outcomes of the Altura endograft seem to be promising, suggesting that the endograft could be safely used either in elective or emergent situations. Further studies with a major number of participants are needed to document its technical and clinical performance, especially in emergency situations that could be amenable to improvement. |
