    Non-Standard Management of Target Vessels With the Inner Branch Arch Endograft: A Single-Center Retrospective Study
    (2022) Torrealba, Jose, I; Spanos, Konstantinos; Panuccio, Giuseppe; Rohlffs, Fiona; Gandet, Thomas; Heidemann, Franziska; Tsilimparis, Nikolaos; Koelbel, Tilo
    Purpose: The purpose of this study was to evaluate early and mid-term results of non-standard management of the supraaortic target vessels with the use of the inner branch arch endograft in a single high-volume center. Material and methods: A single-center retrospective study including all patients undergoing implantation of an inner branch arch endograft from December 2012 to March 2021, who presented a non-standard management of the supraaortic target vessels (any bypass other than a left carotid-subclavian or landing in a dissected target vessel). Technical success, mortality, reinterventions, endoleak (EL), and aortic remodeling at follow-up were analyzed. Results: Twenty-four patients were included. In 17 (71%) cases, the non-standard management was related to innominate artery (IA) compromise (12 with IA dissection, 2 with short IA, 2 with short proximal aortic landing zone that required occlusion of IA, 1 with occluded IA after open arch repair). Two (8%) cases were related to an aberrant right subclavian artery (RSA), 1 patient (4%) due to the concomitant presence of a left vertebral artery (LVA) arising from the arch and an occluded left subclavian artery (LSA), and another patient presented with an occluded LSA distal to a dominant vertebral artery. Three (13%) cases were exclusively related to management in patients with genetic aortic syndromes. Twenty (83%) patients had a previous type A aortic dissection. Ten (42%) patients presented a thoracic or thoracoabdominal aortic aneurysm and 8 (33%) patients an arch aneurysm, 6 of them associated to false lumen (FL) perfusion. There were 2 (8%) perioperative minor strokes, and 1 patient with perioperative mortality. Seven patients presented an early type I endoleak, all resolved at follow-up. Seven patients required reinterventions during follow-up (7 reinterventions related to continuous false lumen perfusion, 3 related to Type Ia endoleak, 2 related to surgical bypass). All patients who presented with FL perfusion had complete FL thrombosis at follow-up. No patient presented aneurysm growth at follow-up. Conclusions: The use of the inner branch arch endograft with a non-standard management of the supraaortic target vessels is a possible option. Despite a high reintervention rate, regression or stability of the aneurysmal diameter was achieved in all the patients with follow-up.

    One-Year Results of ZBIS Iliac Branch Device With an Off-Label Connection Limb
    (2022) Torrealba, Jose; Panuccio, Giuseppe; Rohlffs, Fiona; Gandet, Thomas; Gronert, Catharina; Heidemann, Franziska; Tsilimparis, Nikolaos; Koelbel, Tilo
    Purpose: The purpose of this article is to study 1-year results of Zenith branch iliac endovascular graft (ZBIS) with the off-label use of a 13 mm spiral Z limb to connect to the aortic main body. Materials and Methods: A retrospective review from 2015 to 2019 of all iliac branch devices (IBDs) was performed at 1 institution that were connected to an aortic main body with a 13 mm spiral Z limb and had at least 1-year follow-up with computed tomography (CT). Primary endpoints are freedom from ZBIS separation from the connection limb, endoleak (EL), or reintervention at 1 year. Secondary endpoints are primary and secondary ZBIS patency, presence of any EL, and aortic reinterventions. Results: Of 149 IBDs implanted in this period, 45 ZBIS in 35 patients were connected with a 13 mm limb and had a 1-year CT; 97% of patients had common iliac artery (CIA) aneurysms, 7% of patients had hypogastric artery (HA) aneurysms, and 30% of patients had bilateral ZBIS implantation. Technical success was 98%. In 84% of cases, the Advanta V12 was used as the HA mating stent; 56% of patients had an EL, mostly type II, which resolved spontaneously in 70% at 1 year, and 9% of ZBIS required reinterventions at 1 year (2 for thrombosis, 2 for type Ic EL from HA mating stent). One-year ZBIS primary patency and secondary patency were 96% and 100%, respectively. No EL was noted to be related to the 13 mm connection limb. No migration or separation of the devices occurred. Conclusions: The use of 13 mm spiral Z limb to connect a ZBIS with the main body in our series yields a high technical success rate and good 12-month outcomes without device separation or migration.

    Physician-Modified Endograft With Inner Branches for the Treatment of Complex Aortic Urgencies
    (2022) Torrealba, Jose; Panuccio, Giuseppe; Koelbel, Tilo; Gandet, Thomas; Heidemann, Franziska; Rohlffs, Fiona
    Purpose To describe the use of physician-modified endograft (PMEG) with the exclusive use of inner branches or in combination with fenestrations for the urgent treatment of complex aortic aneurysms. Technique We present two urgent cases. A patient with a 6.8 cm saccular juxtarenal aneurysm and another patient with a contained rupture of the thoracoabdominal aorta right above the celiac trunk (CT). In both cases, a Cook Zenith TX2 thoracic endograft was back-table modified, in the first case by adding three fenestrations and one inner branch for the left renal artery to improve sealing due to its partial involvement in the aneurysm and, in the second case, with the use of two inner branches for the CT and superior mesenteric artery. Both procedures were successful, with uneventful postoperative courses and complete aneurysm exclusion on postoperative CT angiography. Conclusion Use of PMEGs with inner branches is feasible for urgent repair in complex aortic anatomy.

    The preservation of accessory renal arteries should be considered the treatment of choice in complex endovascular aortic repair
    (2022) Torrealba, Jose, I; Koelbel, Tilo; Rohlffs, Fiona; Heidemann, Franziska; Spanos, Kostas; Panuccio, Giuseppe
    Objective: The objective of this study was to evaluate renal function and renal parenchymal length changes secondary to the coverage or preservation of accessory renal arteries (ARAs) in complex aortic repair.
