Background: The aim of this single-center study was to evaluate the early results of the off-the-shelf inner branch E-nside endograft in the treatment of complex aortic aneurysms and thoracoabdominal aortic aneurysms.
Methods: We performed a retrospective analysis of a prospectively maintained database of all patients treated with the E-nside endograft at our institution during the years 2021-2023. Parameters evaluated were technical success, early major adverse events, target vessel patency, and the presence of endoleaks.
Results: In total 16 patients underwent treatment with the E-nside endograft. Six additional patients were evaluated for the device but were excluded due to anatomical considerations. Mean age was 71 (range 59-84) and 14 (88%) were males. Mean aneurysm diameter was 66 mm (range 54-85). Aneurysms treated included thoracoabdominal in 9 (56%), juxtarenal aneurysms in 5 (31%), postdissection aneurysm in 1 (6%) and a type 1A endoleak after a failed endovascular aneurysm repair in 1 (6%). Five of the treated aneurysms were symptomatic. A total of 58 side branches were placed into target visceral arteries. Mean operative time was 190 min (range 150-360). Technical success was achieved in 15/16 of the patients (94%). At 30 days, 1 perioperative mortality and 3 major adverse events occurred, 2 of them branch related.
Conclusions: The E-nside endograft is a feasible option for the treatment of a broad spectrum of aortic pathologies. As it is an off-the-shelf device, it can be used selectively in elective and emergent settings with acceptable 30-day mortality and morbidity. Further follow-up is required to determine the durability of this treatment option and patency of side branches.

Background: During the last years a great progress has been noted in device technology and operator experience in treating complex aortic aneurysms. Fenestrated and branched custom-made devices require detailed preoperative planning and production time that can take ≤12 weeks. During this awaiting period, aortic-related mortality is increased.

Objective: The aim of this study was to report the outcomes of endovascular urgent thoracoabdominal aortic (TAAA) repair, using an off-the-shelf preloaded inner branch device (E-nside; Artivion).
Methods: Data from a physician-initiated national multicenter registry, including patients treated with E-nside endograft (INBREED) were prospectively collected (2020-2024); only urgent cases were included in this study. Primary outcomes were technical success and mortality at 30 days.

The aim of this paper is to propose a sequential deployment technique for the E-nside off-the-shelf endograft that could potentially enhance target visceral vessel (TVV) cannulation and overstenting in narrow aortic anatomies. All data regarding patients consecutively treated in two aortic centers with the E-nside graft employing the partial deployment technique were included in the study cohort and analyzed. To execute the procedure with partial endograft deployment, the device should be prepared before insertion by advancing, under fluoroscopy, all four dedicated 400 cm long 0.

Objective: This study aimed to compare two commercially available off the shelf branched endografts for thoraco-abdominal aortic aneurysm (TAAA) repair, namely the E-nside (Artivion) and Zenith t-Branch (Cook Medical) devices.
Methods: This multicentre retrospective study (2020 - 2023) included patients treated by branched endovascular aortic repair (BEVAR) for TAAA using the inner branched E-nside or the outer branched t-Branch. Endpoints were 30 day technical success and major adverse events (MAEs) as well as one year freedom from target vessel instability and main endograft instability.
Purpose: To analyze the early performance and efficacy of the first commercially available off-the-shelf precannulated multibranched endograft in the endovascular repair of pararenal abdominal aortic aneurysms (PAAAs). The device received European marketing approval in late 2020.
Materials And Methods: Between January 2021 and June 2023, a retrospective analysis of prospectively collected data from all consecutive patients with pAAAs undergoing implantation of the E-nside precannulated inner-branched endograft was conducted in 2 centers.
