Late Open Conversion Following Failure of EVAR and TEVAR: “State of the Art”

Research output: Contribution to journalReview articlepeer-review

Abstract

Abdominal endovascular aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR) have changed the aortic surgery, due to several advantages in terms of reduced morbidity and mortality. However, increasing rate of late complications requiring secondary procedures has been observed over time. Even if the majority of them may be treated by means of endovascular techniques, late open surgical conversion (LOSC) is required in specific situations. This paper aims to provide our single-center experience with LOSCs and an updated review of the literature. From 1995 to 2020, indications and outcomes of patients treated with LOSC for failed EVAR and TEVAR, at our institutions, were analyzed. LOSC was required to treat a broad range of complications that were classified into two main groups: “disease related” and “stent-graft (SG) related.” Among the 121 patients treated with LOSC after EVAR, endoleak (75.2%) represented the most common indication. The overall 30-day mortality rate was 3.3%. A higher mortality rate was associated with infection after EVAR (p. 006). Among the 81 patients treated with LOSC after TEVAR, endoleak (32.1%) was the most common indication. The overall 30-day mortality rate was 13.6% with a higher incidence in the SG-related group (p. 02). LOSC is associated with an increased surgical complexity, in both the abdominal and thoracic area, that results in higher morbidity and mortality rates compared with standard open repair. Depending on the indication to LOSC, specific surgical maneuvers are required to improve clinical outcomes.
