Feasibility and Safety of Exclusively Using Carbon Dioxide in Regular Endovascular Aortic Aneurysm Repair: Results of a Multicentre, Prospective, Zero Iodine Contrast Endovascular Aneurysm Repair Study.

Objective: Carbon dioxide (CO) angiography has emerged as a viable alternative to regular iodinated contrast medium (ICM) for guiding endovascular aneurysm repair (EVAR) procedures. This study aimed to evaluate the feasibility and safety of a standardised EVAR procedure using only CO angiography.

Methods: A prospective, multicentre, national study enrolled consecutive patients between January 2023 and January 2024 with asymptomatic abdominal aortic aneurysms measuring ≥ 55 mm and for whom standard endovascular graft (instructions for use) was anatomically feasible.

The impact of large aneurysm diameter on the outcomes of thoracoabdominal aneurysm repair by fenestrated and branched endografts.

Objectives: Aim of the study was to analyse the impact of preoperative thoracoabdominal aneurysm diameter on the outcomes of fenestrated/branched endografting.

Methods: Patients who underwent endovascular thoracoabdominal repair at 2 European centres (2011-2021) were analysed. Median diameter was calculated; the third quartile was considered a cut-off.

CO Angiography in the Standard and Complex Endovascular Repair of the Abdominal Aorta-A Narrative Review of the Literature.

: Carbon dioxide digital-subtraction angiography (CO-DSA) is an increasingly adopted technique in endovascular aortic repair (EVAR) and fenestrated/branched EVAR (F/B-EVAR); it is used to reduce the amount of iodinate contrast medium (ICM) and prevent postoperative renal function worsening (PO-RFW). Our aim is to report results from the literature on EVAR and F/B-EVAR procedures using CO-DSA, together with wider applications in aortic endovascular treatment. : We performed a literature review by searching electronic databases for published data on CO-DSA during EVAR and F/B-EVAR procedures.

Impact of iliac access in elective and non-elective endovascular repair of abdominal aortic aneurysm.

Endovascular aortic repair (EVAR) is nowadays the establishment treatment for patients with abdominal aortic aneurysm (AAA) both in elective and urgent setting. Despite the large applicability and satisfactory results, the presence of hostile iliac anatomy affects both technical and clinical success. This narrative review aimed to report the impact of iliac access and related adjunctive procedures in patients undergoing EVAR in elective and non-elective setting.

Five-year sex-related outcomes of thoracic endovascular aortic repair in the Global Registry for Endovascular Aortic Treatment.

Objective: The impact of sex on outcomes of thoracic endovascular aortic repair (TEVAR) represents an area of increased interest over the last decade, and long-term data are lacking. The aim of the present study was to investigate sex-related differences in long-term outcomes after TEVAR using real-world data from the Global Registry for Endovascular Aortic Treatment.

Methods: Data were obtained retrospectively after querying the multicenter, sponsored Global Registry for Endovascular Aortic Treatment.
