Expert-Based Narrative Review on Contemporary Use of an Off-The-Shelf Multibranched Endograft for Endovascular Treatment of Thoracoabdominal Aortic Aneurysms: Device Design, Anatomical Suitability, Technical Tips, Perioperative Care, Clinical Applications, and Real-World Experience. Ann Vasc Surg 2024; 108:98-111. [PMID: 38942377 DOI: 10.1016/j.avsg.2024.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 05/10/2024] [Accepted: 05/15/2024] [Indexed: 06/30/2024]
Abstract
Advanced endovascular techniques, such as fenestrated stent grafts, are nowadays available that permit minimally invasive treatment of complex abdominal aortic aneurysms. However, thoracoabdominal aortic aneurysm patients have anatomic limitations to fenestrated stent-grafts given a large lumen, that is, the gap between the endograft and the inner aortic wall. This has led to the development of branched endovascular aneurysm repair as the ideal option for such patients. The Zenith t-Branch multibranched endograft (Cook Medical, Bloomington, IN), which has been commercially available in Europe to treat thoracoabdominal aortic aneurysm since June 2012, represents a feasible off-the-shelf alternative for treatment of such pathologies, especially in the urgent setting, for patients who cannot wait the time required for manufacturing and delivery of custom-made endografts. The device's anatomical suitability should be considered, especially for female patients with smaller iliofemoral vessels. Several tips may help deal with particularly complex scenarios (such as, for instance, in case of narrow inner aortic lumens or when treating patients with failure of prior endovascular aneurysm repair), and a broad array of techniques and devices must be available to ensure technical and clinical success. Despite promising early outcomes, concerns remain particularly regarding the risk for spinal cord ischemia and further assessment of long-term durability is needed, including the rate of target vessel instability and need for secondary interventions. As the published evidence mainly comes from retrospective registries, it is likely that reported outcomes may suffer from an intrinsic bias as most procedures reported to date have been carried out at high-volume aortic centers. Nonetheless, with the never-ceasing adoption of new and refined techniques, outcomes are expected to ameliorate.

Abstract
OBJECTIVE To present a single-center prospective study of 126 consecutively treated patients who underwent endovascular repair of a thoracoabdominal aortic aneurysm with the physician-modified, nonanatomic-based Unitary Manifold (UM) device. METHODS Data were collected from 126 consecutive all-comer patients treated with the physician-modified, nonanatomic-based UM from 2015 to 2023. Treatment was performed at a single center by a single physician under a Physician Sponsored Investigation Exemption G140207. RESULTS The UM was indicated for repair of all Crawford extents including juxtarenal, pararenal, and short-neck infrarenal aneurysms (<10 mm) in 126 consecutive patients. Patients were not excluded from the study based on presentation, extent of aneurysm or dissection, or history of a spinal cord event. Patients with a thoracoabdominal aortic aneurysm were categorized by Crawford classification: types I and V (3.3%, n = 4), type II (3.3%, n = 4), type III (1%, n = 1), and type IV (93.3%, n = 117). The type IV classification patients were further categorized with 33 (28.2%) true type IV, 68 (58.1%) pararenal or infrarenal, and 16 (13.7%) with dissection. Technical success was 99.2% (n = 125). The most common major adverse event within both 30 days and 365 days of all patients was respiratory failure (11.9%, n = 15, and 13.5%, n = 17, respectively). One patient (0.8%) experienced persistent paraplegia at 365 days. Reintervention for patients at 365 days was 5.6% (n = 7). Of the 444 branches stented, the primary patency rate was remarkably high as only three patients (2.4%) required reintervention due to loss of limb patency within 365 days. Aneurysm enlargement (≥5 mm) occurred in 1.6% (n = 2) patients, and no patients experienced aneurysm rupture. No patients underwent conversion to open repair. The aneurysm-related mortality at 365 days for all patients was 4.0% (n = 5), whereas all-cause mortality was 16.7% (n = 21). Physician-modified endograft device integrity failure was not observed in any patient. CONCLUSIONS The UM device demonstrated remarkable technical surgical success, treatment success, and device patency rates with very reasonable major adverse events and reintervention rates. This study is the most representative example of the general population in comparison with other studies of off-the-shelf devices, with 126 consecutive all-comer patients with diverse pathologies.

Three-year outcomes of off-the-shelf Gore thoracoabdominal multibranch endoprosthesis and physician-modified endografts for complex abdominal and thoracoabdominal aortic aneurysms. J Vasc Surg 2024:S0741-5214(24)01778-6. [PMID: 39181341 DOI: 10.1016/j.jvs.2024.07.107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 07/16/2024] [Accepted: 07/19/2024] [Indexed: 08/27/2024]
Abstract
OBJECTIVE Fenestrated-branched endovascular aortic repair (FB-EVAR) has shown favorable outcomes for repair of complex aneurysms and thoracoabdominal aortic aneurysms. Physician-modified endografting (PMEG) and the Gore thoracoabdominal multibranch endoprosthesis (TAMBE) provide custom and off-the-shelf devices for FB-EVAR, respectively. This study compares the outcomes of TAMBE and PMEG at a single institution. METHODS A retrospective review of patients who underwent TAMBE as part of the multicenter pivotal trial or PMEG as part of a prospective physician-sponsored investigational device exemption at a single institution between 2020 and 2022 were completed. Patient demographics, characteristics, and perioperative and midterm outcomes were compared. RESULTS A total of 68 patients were included, with 12 in the TAMBE group and 56 in the PMEG group. Baseline characteristics were comparable between groups. Aneurysm type was most often thoracoabdominal aortic aneurysm in both groups (58% TAMBE and 52% PMEG). TAMBE had a higher rate of upper extremity access (100% vs 63%; P = .013) and longer mean procedure time (247 ± 36 minutes vs 189 ± 49 minutes; P < .001). Other intraoperative metrics were similar between groups. Technical success was 100% in TAMBE and 95% in PMEG (P = .412). There was no 30-day mortality in either group. No major adverse events occurred with TAMBE, whereas in PMEG cases, 2% had respiratory failure, 2% required dialysis, and 4% experienced spinal cord ischemia. Although the overall endoleak rates were similar (50% of TAMBE vs 41% of PMEG; P = .57), type II endoleaks accounted for all of the endoleaks in the TAMBE group, whereas type I or III endoleaks were seen in 11% of PMEG patients. At a median follow-up of 26.7 months for the TAMBE group and 21.2 months for the PMEG group, target vessel instability was seen in 10.4% of TAMBE, and 6.9% of PMEG targeted branches (P = .401). Reintervention was required in 33% of TAMBE patients and 27% of PMEG patients (P = .646). Estimated freedom from reintervention rates at 3 years were similar (56% TAMBE vs 62% PMEG, log-rank P = .910). Freedom from visceral renal target vessel instability at 3 years was 89% for both groups (log-rank P = .459). The Kaplan-Meier 3-year estimated survival was 100% for patients in the TAMBE group and 77% for patients in the PMEG group (log-rank P = .157). CONCLUSIONS At experienced centers, FB-EVAR can be completed with PMEG or TAMBE with comparable, excellent perioperative and midterm outcomes. Reinterventions are frequently needed for both TAMBE and PMEG.

Urgent endovascular repair of juxtarenal/pararenal aneurysm by off-the-shelf multibranched endograft. J Vasc Surg 2024:S0741-5214(24)01500-3.

Abstract
OBJECTIVE To report outcomes of urgent juxtarenal/pararenal aneurysms (J/P-AAAs) managed by off-the-shelf multibranched thoracoabdominal endografts (Cook, T-branch). METHODS In this observational, multicenter, retrospective study, patients with J/P-AAAs treated by urgent endovascular repair by T-branch in 23 European aortic centers, from 2013 to 2023, were analyzed. Contained J/P-AAAs rupture, presence of related symptoms, and aneurysm diameter of >70 mm were considered as indication for urgent repair. Technical success (TS), spinal cord ischemia (SCI), and 30-day/hospital mortality were assessed as early outcomes. Survival, freedom from reinterventions, and target artery instability (TAI) were evaluated during follow-up. RESULTS Overall, 197 patients (J-AAAs, n = 64 [33%]; P-AAAs, n = 95 [48%]; previous failed endovascular aneurysm repair (EVAR), n = 38 [19%]) were analyzed. The mean age and aneurysm diameter was 75 ± 8 years and 76 ± 4 mm, respectively. The American Society of Anesthesiologists score was 3 and 4 in 118 (60%) and 79 (40%) patients. Rupture, symptoms, and diameter of >70 mm were present in 51 (26%), 110 (56%), and 53 (27%) patients, respectively. An adjunctive proximal thoracic endograft was used in 28 cases (14%). The mean aortic coverage between the upper portion of the endograft and the lowest renal artery was 154 ± 49 mm. Single-stage repair and cerebrospinal fluid drainage were reported in 144 (73%) and 53 (27%) cases, respectively. TS was achieved in 182 (92%) cases (rupture, 84% vs no rupture, 95%; P = .02). Failures consist of TA loss (11 [6%]: renal artery, 9; celiac trunk, 2), type I to III endoleaks (2 [1%]), and 24-h mortality (2 [1%]). Rupture was a risk factor for technical failure (P = .02; odds ratio [OR], 3.8; 95% confidence interval [CI], 1.1-12.1). Overall, 15 patients (8%) had persistent SCI (rupture, 14% vs no rupture, 5%) with 11 (6%) , of paraplegia (rupture, 10% vs no rupture, 5%; P = .001). Rupture (P = .04; OR, 3.1; 95% CI, 1.1-8.9) and adjunctive proximal thoracic endograft (P = .01; OR, 4.1; 95% CI, 1.3-12.9) were risk-factors for SCI. Twenty-two patients (11%) died within 30 days or during a prolonged hospitalization. Previous failed EVAR (P = .04; OR, 3.6; 95% CI, 1.1-12.3), paraplegia (P < .001; OR, 9.9; 95% CI, 1.6-62.2) and postoperative mesenteric complications (P = .03; OR, 10.4; 95% CI, 1.2-93.3), as well as cardiac (P = .03; OR, 8.2; 95% CI, 2.0-33.0) and respiratory (P < .001; OR, 10.1; 95% CI, 2.9-35.2) morbidities were associated with 30-day/hospital mortality. The mean follow-up was 19 ± 5 months. The estimated 3-year survival and freedom from reinterventions was 58% and 77%, respectively. TAI occurred in 27 patients (14%) (occlusion, 15; endoleak, 14) with an estimated 3-year freedom from TAI of 72%. CONCLUSIONS Urgent repair of J/P-AAAs by T-branch is feasible and effective with satisfactory TS and 30-day/hospital mortality in high-risk patients. However, extensive aortic coverage is necessary, leading to a non-negligible SCI rate, especially in case of aortic rupture or when adjunctive thoracic endografts are necessary. Previous failed EVAR and postoperative mesenteric complications, as well as cardiac and respiratory morbidities were associated with 30-day/hospital mortality and should be subjected to more research for the purposes of improving outcomes.

Abstract
We describe the feasibility and safety of a standardized approach for four-fenestrated physician-modified endograft (PMEG) placement to treat complex abdominal aortic aneurysms using the Valiant Captivia platform (Medtronic). The standardization is based on specific selection criteria for anatomical feasibility, measurement method, and modification technique of a single endograft type. Six cases (two juxtarenal, two pararenal, and two type IV thoracoabdominal aneurysms) were treated, with 24 target vessels incorporated with fenestrations. Four cases were treated in an urgent setting and two were elective. The time modification required was 121 ± 18 minutes. Technical success was 100%, with no mortality or complications at 30 days. Postoperative computed tomography at 3 months demonstrated complete aneurysm exclusion, without a type I or III endoleak, no main graft- or fenestration-related loss of integrity, and no target vessel misalignment or stent fracture. The present standardized approach seems safe and feasible and might represent an initial benchmark for comparison with future studies.

Partial Deployment to Save Space for Vessel Cannulation When Treating Complex Aortic Aneurysms with Narrow Paravisceral Lumen Is Also Feasible Using Inner-Branched Pre-Cannulated Endografts. J Clin Med 2024; 13:3060. [PMID: 38892771 PMCID: PMC11172520 DOI: 10.3390/jcm13113060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2024] [Revised: 05/21/2024] [Accepted: 05/22/2024] [Indexed: 06/21/2024] Open
Abstract
Introduction: 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. Methods: 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 0.018″ non-hydrophilic guidewires until their proximal ends reach the cranial graft's edge. Anticipating this guidewire placement prevents the inability to do so once the endograft is partially released, avoiding potentially increased friction inside the constricted pre-loaded microchannels. The endograft is then advanced and deployed in the standard fashion, stopping just after the inner branch outlets are fully expanded. Tip capture is released, and the proximal end of the device is opened. Visceral vessel bridging is completed from an upper access in the desired sequence, and the graft is fully released after revascularizing one or more arteries. Preventing the distal edge of the graft from fully expanding improves visceral vessel cannulation and bridging component advancement, especially when dealing with restricted lumina. Results: A total of 26 patients were treated during the period December 2019-March 2024 with the described approach. Procedure was performed in urgent settings in 14/26 cases. The available lumen was narrower than 24 mm at the origin of at least one target vessel in 11 out of 26 cases performed (42.3%). Technical success was obtained in 24 out of 26 cases (92.3%), with failures being due to TVVs loss. No intraoperative death or surgical conversion was recorded, and no early reintervention was needed in the perioperative period. Clinical success at 30 days was therefore 80.7%. Conclusions: The described technique could be considered effective in saving space outside of the graft, allowing for safe navigation and target vessel cannulation in narrow visceral aortas, similar to what has already been reported for outer-branched endografts.

Unintended Exchange of Target Vessels for Celiac Trunk and Superior Mesenteric Artery Branches in Complex Endovascular Aortic Repair. J Endovasc Ther 2024:15266028241251985. [PMID: 38708984 DOI: 10.1177/15266028241251985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/07/2024]
Abstract
PURPOSE The treatment of thoracoabdominal aortic aneurysms (TAAAs) using branched endovascular aortic repair (BEVAR) is safe and effective. During deployment, the superior mesenteric artery (SMA) branch can unintentionally open into the celiac trunk (CT) ostium and switched catheterization of the SMA from the CT branch and the CT from the SMA branch can be used as an alternative technique in these cases. This study aimed to investigate the outcome of exchanging the intended target vessels (TVs) for the CT and SMA branches during BEVAR. MATERIALS AND METHODS A single-center retrospective analysis of patients with TAAAs who underwent BEVAR, using off-the-shelf or custom-made devices (CMDs), with an unintended exchange of TVs for the CT and SMA branches was performed. RESULTS Between 2014 and 2023, 397 patients were treated with BEVAR for TAAA. Eighteen (4.5%) of those patients were treated with an exchange of TVs for the CT and SMA branches. T-branch was used in 9 cases (50%) and the remaining patients were treated with CMDs. Twelve patients were treated electively, 3 were symptomatic and 3 presented with rupture. Of 36 mesenteric TVs in those 18 patients, 34 (94%) were catheterized successfully, including all 18 SMAs and 16 of the 18 CTs. No branch stenosis or occlusion of the switched mesenteric TVs was detected during follow-up. During 30-day follow-up, 3 patients died and during a median follow-up of 3 (interquartile range [IQR]: 1-15) months 3 more patients died. None of the deaths or the 2 unintended reinterventions was induced by the mesenteric TV exchange. The median hospital stay was 14 (IQR: 9-22) days with a median of 4 (IQR: 2-11) days at the intensive care unit. CONCLUSION The exchange of the mesenteric TVs for the CT and SMA branches during BEVAR with off-the-shelf and CMD endografts is feasible with good TV patency and freedom from TV-related reinterventions. This alternative technique should be considered in selected cases when direct catheterization via the intended branch is deemed more time-consuming or not feasible. CLINICAL IMPACT This is the first description of using an exchange of target vessels for the celiac trunk and the superior mesenteric artery branches in patients with thoracoabdominal aortic aneurysms undergoing BEVAR, using off-the-shelf or custom-made devices. The high success rate as well as the good clinical results without any branch stenosis or occlusion during follow-up highlight the feasibility of this alternative technique. It could help in challenging cases when catheterization of the intended target vessels is not possible or too time consuming, resulting in higher success rates of BEVAR and better clinical results.

Abstract
Vascular plugs are an evolving family of vessel occluders providing a single-device embolization system for large, high-flow arteries. Nitinol mesh plugs and polytetrafluoroethylene membrane plugs are available in different configurations and sizes to occlude arteries from 3 to 20 mm in diameter. Possible applications during complex endovascular aortic procedures are aortic branch embolization to prevent endoleak or to gain an adequate landing zone, directional branch occlusion, and false lumen embolization in aortic dissection. Plugs are delivered through catheters or introducers, and their technical and clinical results are comparable to those of coil embolization. Plugs are more accurate than coils as repositionable devices, less prone to migration, and have fewer blooming artifacts on postoperative computed tomography imaging. Their main drawback is the need for larger delivery systems. This narrative review describes up-to-date techniques and technology for plug embolization in complex aortic repair.

Abstract
BACKGROUND The aim of this study was to evaluate the anatomical feasibility of current available fenestrated endografts (FEVAR) and on-label chimney technique (EnChEVAR) in patients with complex abdominal aortic aneurysms (C-AAA). METHODS Feasibility of EnChEVAR (Endurant II/IIS CE-marked [Medtronic]) and 4 types of FEVAR (Zenith Fenestrated CE-marked, Zenith Fenestrated Low-Profile [LP] custom-made device [CMD] [Cook Medical], Fenestrated Anaconda LoPro90 CMD, Fenestrated Treo CMD [Terumo Aortic]) was assessed according to the manufacturer's instructions for use. Computed tomography angiograms of patients with C-AAA previously included in the Protagoras 2.0 study were retrospectively reviewed. The aortic coverage was ideally planned to involve a maximum of two chimney grafts or fenestrations. RESULTS Iliac access and aortic neck of 73 C-AAAs were analyzed. The overall feasibility was significantly different between EnChEVAR (33%) and FEVAR (Zenith Fenestrated 15%, Zenith Fenestrated LP 15%, Fenestrated Anaconda LoPro90 45%, Fenestrated Treo 48%). The iliac access feasibility was significantly lower for Zenith Fenestrated with standard profile compared to all other grafts. The aortic neck feasibility was significantly higher for EnChEVAR and both Terumo Aortic fenestrated stent grafts, compared to both Cook Medical grafts. The treatment using any of the three current available fenestrated grafts with lower profile (Zenith Fenestrated LP, Fenestrated Anaconda LoPro90, Fenestrated Treo) would have been feasible in 71% of the cases. CONCLUSIONS Most of the patients treated by ChEVAR would have not been treated by first generation fenestrated stent graft. The current available fenestrated endografts, with lower profile and suitable also for angulated necks, increase the anatomical feasibility.

Abstract
OBJECTIVE To investigate outcomes of a novel, off the shelf multibranched endovascular stent graft for the treatment of thoraco-abdominal aortic aneurysm (TAAA) and pararenal abdominal aortic aneurysm (PAAA). METHODS A prospective, single centre study including 15 patients (mean age, 63.4 ± 10.7 years; 13 male) with TAAA or PAAA treated from October 2019 to March 2021 with a G-Branch endograft (Lifetech Scientific, Shenzhen, China) featuring a mixed multibranch design with two inner and two outer branches for reconstruction of the visceral and bilateral renal arteries, respectively. Follow up assessments were scheduled before discharge and at 30 days, six and 12 months after the index procedure. Annual telephone interviews were performed beyond the initial 12 months. The Kaplan-Meier method was used to estimate cumulative mortality and morbidity rates after endovascular repair. RESULTS Technical success was achieved in all 15 patients. Nine patients (60%) had TAAA and six (40%) had PAAA (mean maximum aneurysm diameter, 73.7 ± 15.8 mm). The median follow up was 31.4 months (range, 10.1 - 44.0 months). At 30 days, there was no death and 7% morbidity (one case of temporary spinal cord ischaemia on Day 4). At one year, the mortality rate was 7% (one death from stroke at 10 months) and morbidity was 13% (one other case of renal function decline at six months). There were no aneurysm dilatations, re-interventions, or access related complications, and two (13%) persistent type II endoleaks. The one year primary branch patency rate was 100% for the four renovisceral arteries in all 13 patients who underwent computed tomography examinations. One patient died of hepatocellular carcinoma 29 months post-operatively, resulting in an estimated three year mortality rate of 13%. CONCLUSION The G-Branch endograft yielded high technical success with good early and midterm outcomes for the treatment of TAAA and PAAA. A large multicentre study is warranted.

Effect of narrow paravisceral aorta on target vessel instability after fenestrated and branched endovascular aortic repair. J Vasc Surg 2024; 79:217-227.e1. [PMID: 37852334 DOI: 10.1016/j.jvs.2023.09.039] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 09/16/2023] [Accepted: 09/22/2023] [Indexed: 10/20/2023]
Abstract
OBJECTIVE To investigate the effect of narrow paravisceral aorta (NPA) on target vessel instability (TVI) after fenestrated-branched endovascular aortic repair. METHODS We conducted a single-center retrospective study (2014-2023) of patients treated by fenestrated-branched endovascular aortic repair for thoracoabdominal aortic aneurysms (TAAA) or pararenal aortic aneurysms. The paravisceral aorta was defined as the aortic segment limited by the diaphragmatic hiatus proximally and the emergence of lower renal artery distally, and was considered "narrow" in case of a minimum inner diameter of <25 mm. The minimum aortic diameter, location, longitudinal extension, angulation, calcification, and thrombus thickness of NPA were evaluated at the preoperative computed tomography angiogram. End points were 30-day technical success and freedom from TVI. RESULTS There were 142 patients with JRAA/pararenal aortic aneurysm (n = 85 [59%]) and extent IV (n = 24 [17%]) or extent I-III (n = 33 [23%]) TAAA, with 513 target arteries successfully incorporated through a fenestration (n = 294 [57%]) or directional branch (n = 219 [43%]). A NPA was present in 95 patients (70%), 73 (86%) treated by fenestrated endovascular aortic repair (FEVAR) and 22 (39%) by branched endovascular aortic repair (BEVAR). The overall 30-day mortality was 2% and technical success was 99%, without differences between NPA and non-NPA (P = .99). Kaplan-Meier estimated freedom from TVI at 4 years was 82%, 81% (95% CI, 75-95) in patients with a NPA and 80% (95% CI, 68-94) and in those without NPA (P = .220). The result was maintained for both FEVAR (NPA: 81% [95% CI, 62-88]; non-NPA: 76% [95% CI, 60-99]; P = .870) and BEVAR (NPA: 77% [95% CI, 69-99]; non-NPA: 80% [95% confidence interval (CI) 66-99]; P = .100). After multivariate analysis, the concomitant presence of a NPA <20 mm and angulation of >30° was significantly associated with TVI in FEVAR (HR, 3.21; 95% CI, 1.03-48.70; P = .036), being the result mostly driven by target vessel occlusion. In BEVAR, a NPA diameter of <25 mm was not associated with TVI (HR, 2.02; 95% CI, 0.59-5.23; P = .948); after multivariate analysis, the use of outer branches in case of a NPA longitudinal extension of >25 mm (hazard ratio [HR], 3.02; 95% CI, 1.01-36.33; P = .040) and NPA severe calcification (HR, 1.70; 95% CI, 1.00-22.42; P = .048) were associated with a higher chance for TVI. CONCLUSIONS FEVAR and BEVAR are both feasible in cases of NPA and provide satisfactory target vessels durability. The use of outer branches should be avoided in cases with an inner aortic diameter of <25 mm with a longitudinal extension of >25 mm or moderate to severe NPA calcifications. In FEVAR, bridging stent patency may be negatively influenced by NPA of <20 mm in association with aortic angulation of >30°.

Abstract
OBJECTIVES To evaluate the feasibility of thoracic endovascular aortic repair (TEVAR) using the Ankura™ device (Lifetech Scientific, Shenzhen, China) with left subclavian artery (LSA) in-situ fenestration (ISF) using an adjustable puncture device system. METHODS It is a single center, retrospective, financially unsupported cohort study of TEVAR performed from 16 February 2007 to 10 January 2023. Inclusion criteria were isolate LSA revascularization for elective or urgent/emergent "zone 2" TEVAR, and the availability of the preoperative computed tomography angiography. RESULTS Post-hoc analysis identified 52 TEVARs. There were 39 (75.0%) males, and 13 (25.0%) females: median age was 74.5 years (IQR, 65.5-78). Index TEVAR was performed for atherosclerotic aneurysm in 27 (51.9%) cases, dissection-related diseases in 18 (34.6%), penetrating aortic ulcer in 5 (9.6%), and blunt traumatic aortic injury in 2 (3.8%). Access-vessel feasibility rate of TEVAR using the Ankura™ device would have been 98.1% (51/52). Considering the morphology of the aortic arch, ISF TEVAR feasibility would have been 61.5% (32/52). Binary logistic regression analysis identified LSA angulation (OR: 1.1, 95%CI: 1.03-1.14, p = 0.003) to be associated with ISF feasibility using this endograft and a self-centering adjustable needle-based puncture device. CONCLUSIONS Potential feasibility of TEVAR using the Ankura™ endograft with ISF using a self-centering adjustable needle system was 61.5%. Left subclavian artery angulation seems to be the most important and limiting anatomical constraint.

Abstract
INTRODUCTION Endovascular solutions to emergent juxtarenal and pararenal abdominal aortic aneurysms (AAAs) are complicated. Endovascular aortic repair (EVAR) with in situ laser fenestration (ISLF) is promising but requires a period of visceral ischemia. With an off-the-shelf, single superior mesenteric artery (SMA)-fenestrated device mesenteric ischemia is avoided and renal ischemia decreased. The aim was to develop an optimized design of such an endograft suitable for >90% of juxtarenal and pararenal AAAs. METHODS Single-center analysis on 44 consecutive preoperative CTs for previously elective fenestrated EVARs for juxtarenal and pararenal aneurysms. Anatomical characteristics were analyzed to define: (1) shortest aortic coverage above SMA fenestration to achieve ≥4 cm seal; (2) feasibility of a scallop for the celiac artery; (3) shortest distance between the SMA and lowest renal, to facilitate renal ISLF in a straight endograft; (4) distance from the lowest renal to the aortic bifurcation, to allow an overlapping zone >40 mm with a bifurcated stent graft; (5) aortic diameter in the sealing zone, for optimal proximal stent graft diameter with 10% to 30% oversizing; (6) the final design was then tested on individual level. RESULTS (1) The stent graft needs to start 40 mm above the SMA fenestration to achieve a 4 cm sealing zone in >90% of cases. (2) A proximal sealing zone of 40 mm without a scallop covers 77% of celiac arteries. With an addition of a 20 mm deep, 20 mm wide scallop at 12:30, the stent graft still covers 27% of celiacs. This suggests that a scallop would not be practically feasible. (3) In >90% of cases, the lowest renal was <31 mm from the SMA, suggesting that the tapering should start 30 mm below the SMA. (4) The distance from the lowest renal to the aortic bifurcation ranged from 82 to 166 mm. This allows for a 20 mm tapering and 50 mm straight part in all cases. (5) The 5th and 95th percentile of the aortic diameter in the sealing zone was 22 and 31 mm, respectively. Thus, 2 different stent graft diameters (28 and 34 mm) would fit >90% of cases. (6) The final design was suitable in 91% cases. CONCLUSIONS Two sizes of a single-fenestrated aortic stent graft without scallop cover >90% of juxtarenal and pararenal anatomies. CLINICAL IMPACT Emergent juxta- and pararenal aortic aneurysms is a difficult clinical scenario that continuously challenges physicians. An endovascular option is in situ laser fenestrated endografts. One risk with these is the complete visceral ischemia occurring before the fenestrations are completed. An off-the-shelf single-fenestrated stent graft facilitates the treatment by removing the ischemia time for the SMA and reducing the ischemia time for the celiac and renal arteries thus decreasing the risk of visceral ischemia complications.

Abstract
The absence of an adequate ileo-femoral access is usually considered an absolute contraindication to fenestrated and branched aortic repairs. Alternative routes and dedicated stent-graft designs have been advocated. Hereby, we describe the case of a 73-year-old man with a recurrent type IV thoracoabdominal aortic aneurysm and complete thrombotic pararenal aortic occlusion treated successfully with a tri-branch custom-made endograft deployed via a transaxillary access.

Abstract
Thoracic and thoracoabdominal aortic aneurysms are more common in men. Yet, females often have worse outcomes, fewer interventions, and lower treatment rates. Females have also benefited less from the research and treatment of those diseases than men. Understanding sex- and sex-specific differences in thoracic and thoracoabdominal aortic aneurysms can improve care delivery, reduce disparities, and optimize outcomes for females with thoracic aortic aneurysms and thoracoabdominal aortic aneurysms. The authors reviewed the literature on the presentation and outcomes of thoracic and thoracoabdominal aortic aneurysms in females, discussing the existing gaps and future directions to address them.

Abstract
OBJECTIVE To preliminarily evaluate the safety and efficacy of the WeFlow-JAAA endograft, a novel off-the-shelf device designed for the repair of juxtarenal abdominal aortic aneurysms (JRAAAs) and pararenal abdominal aortic aneurysms (PRAAAs). METHODS This prospective single-arm first-in-human clinical trial included patients with JRAAAs (infrarenal necks ≤10 mm) or PRAAAs with at least a 5 mm sealing zone below the superior mesenteric artery (SMA) who underwent endovascular repair using the WeFlow-JAAA endograft system. With this system, the celiac artery was addressed with a wide scallop, the renal arteries (RAs) were addressed with 2 standard inner branches, and the SMA was addressed with a "mini-inner-cuff" reinforced fenestration. The primary efficacy endpoint was the clinical success at 12 months. The primary safety endpoint was the freedom from major adverse events (MAEs) in the first 30 days after surgery. RESULTS Fifteen patients (all men; mean age 68.5±6.0 years) were enrolled between October 2019 and August 2021. The median infrarenal neck length was 0 mm (IQR, 0-4 mm). Technical success was achieved in all patients. No MAEs occurred in the first 30 days. The mean fluoroscopy time was 73.1±27.8 minutes, and the mean volume of contrast media was 130.7±29.4 mL. Clinical success was maintained in all patients at 12 months. No aortic-related deaths, aneurysm rupture, type I or type III endoleak, or open surgery conversion occurred during the follow-up period. The secondary intervention was required only in 1 patient who developed an occluded right RA stent 14 months after the procedure. CONCLUSION The WeFlow-JAAA endograft device appears to be safe and efficacious in selected patients with JRAAAs or PRAAAs with more than 5 mm sealing zone below SMA. Large-scale, multicenter, and prospective studies with long-term follow-ups are ongoing to validate our findings in China. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT04745546 (URL: Guo's Visceral Arteries Reconstruction: The First in Man Study of WeFlow-JAAA Stent Graft System-Full-Text View-ClinicalTrials.gov). CLINICAL IMPACT The first-in-human clinical trial of the WeFlow-JAAA endograft system demonstrates promising safety and efficacy in treating juxtarenal abdominal aortic aneurysms (JRAAAs) and partial pararenal abdominal aortic aneurysms (PRAAAs). This innovative off-the-shelf device offers a potential alternative to traditional endovascular aortic repair. The successful outcomes, including technical success in all patients, freedom from major adverse events, and maintenance of clinical success at 12 months, suggest a potential shift in clinical practice towards using the WeFlow-JAAA endograft system for selected patients. This study paves the way for larger-scale, multicenter, prospective studies to further validate its long-term safety and efficacy, offering clinicians a new option for managing complex abdominal aortic aneurysms.

Abstract
PURPOSE To illustrate the technique of antegrade in situ laser fenestration (ISLF) on a predesign custom-manufactured stent-graft with single reinforced fenestration for use in emergency endovascular repair of complex abdominal aortic aneurysms (AAAs). TECHNIQUE A short custom-made device (CMD) fenestrated graft was predesigned with a single preloaded 8 mm strut-free fenestration at 12 o'clock position. A modified preloaded system was used to allow unilateral access from the distal port if necessary. After bilateral percutaneous femoral access, the graft was deployed under fusion guidance with the CMD fenestration matching the superior mesenteric artery (SMA) origin and immediately bridged as per standard technique. The aneurysm was then excluded with a bifurcated device. A large steerable sheath was used to allow for sequential antegrade laser in situ fenestration and stenting of the renal arteries. CONCLUSIONS Single-vessel customized short fenestrated grafts for the SMA and antegrade in situ laser renal fenestrations are technically feasible for repair of acute complex AAAs even after previous infrarenal reconstruction. It could become an off-the-shelf solution to limit aortic coverage and reno-visceral ischemia, even in patients with a narrow aortic diameter at the renal level. CLINICAL IMPACT Single-vessel precustomized short fenestrated grafts for the SMA combined with renal artery antegrade ISLF can be a feasible option for the acute repair of patients with complex aneurysms and a narrow aortic diameter at the reno-visceral segment. It may limit aortic coverage and reno-visceral ischemic time and also be applicable after previous infrarenal endovascular aneurysm repair (EVAR).

Abstract
The remarkable advances in technology and devices in the last two decades have made possible the endovascular repair of complex abdominal (cAAA) and thoracoabdominal (TAAA) aortic aneurysms with challenging anatomy. To date, despite the creation of multiple fenestrated/branched endografts intended to treat these difficult cases, in the USA, many of them remain available only under physician sponsored investigational device exemption (PSIDE) protocols in few institutions. The Gore Thoracoabdominal Branched Endoprosthesis (TAMBE; W.L. Gore & Associates, Flagstaff, AZ, USA) investigational device is a four-branched off-the-shelf (OTS) endograft that concluded an early feasibility study in 2016 and is currently finalizing a pivotal trial in pursuit of approval from the Food and Drug Administration. This article discusses the TAMBE early feasibility multicenter study results, the most relevant features of this device, its anatomical feasibility, and the impressions about this endograft as an OTS option for the treatment of CAAA and TAAA.

Abstract
INTRODUCTION The aim of the present study is to perform a systematic review of published papers regarding the suitability of the current off-the-shelf (OTS) devices for endovascular thoracoabdominal aortic aneurysm (TAAA) repair. EVIDENCE ACQUISITION A systematic review of the MEDLINE database via PubMed was performed in March 2023. All studies reporting the outcomes of the three currently available OTS stent-grafts: the Zenith t-Branch (Cook Medical, Bloomington, IN, USA), the Gore Excluder thoracoabdominal branch endoprosthesis (TAMBE; W.L. Gore & Associates, Flagstaff, AZ, USA) and the E-nside Multibranch Stent-Graft System (Artivion, Kennesaw, GA, USA), were retrieved and further analyzed. The main endpoints were technical success, reintervention rate, and primary branch patency. Theoretical feasibility studies of these OTS devices were also included and separately analyzed. EVIDENCE SYNTHESIS A total of 19 studies were published between 2014 and 2023. Thirteen clinical studies and six theoretical feasibility studies were included. Eleven studies reported the clinical outcomes of the t-Branch stent-graft, one detailed the observational results of the use of the E-nside endoprosthesis, and one described the TAMBE stent-graft results. The following data primarily involve the t-Branch device outcomes. A total of 1131 patients that underwent aneurysm repair using an OTS stent-graft were identified. Among those, 1002, 116 and 13 patients received a t-Branch, E-nside, and TAMBE stent-grafts, respectively. A total of 767 (67.8%) were men, with a mean age of 71.6±7.4 years old, and a mean Body Mass Index (BMI) of 26.3±3.8 kg/m2. Technical success ranged from 64% to 100%. A total of 4172 target visceral vessels (TVV) were planned for bridging, with a success rate ranging from 92 to 100%. The total of early and late reinterventions reported were 64 and 48, respectively, mainly due to endoleaks and visceral branch occlusions. Among the theoretical feasibility studies, six described the feasibility of the t-Branch device in a total of 661 patients, two described the E-nside and the TAMBE devices feasibility comprising 351 patients for each stent-graft. The overall feasibility of the t-Branch device varied from 39% to 88%, the E-nside from 43% to 75%, and the TAMBE stent-graft ranged from 33% to 94%. CONCLUSIONS This systematic review demonstrated a good suitability for the use of OTS endografts for the treatment of TAAA.

Abstract
PURPOSE This article aims at investigating the outcomes of percutaneous access via the first versus third axillary artery (AXA) segments with closure devices during aortic procedures. MATERIALS AND METHODS All patients receiving percutaneous AXA access closed with Perclose ProGlide device (Abbott, Santa Clara, California) from 2008 to 2021 were included in a retrospective multicenter registry (NCT: 04589962). Efficacy endpoint was the technically successful percutaneous procedure (no open conversion). Safety endpoints were stroke and access complications according to the Valve Academic Research Consortium-3 reporting standards. The first (AXA1) or third (AXA3) axillary puncture sites were compared. RESULTS A total of 412 percutaneous AXA accesses were included: 172 (42%) in AXA1 and 240 (58%) in AXA3. Left AXA was catheterized in 363 cases (76% of AXA1 vs 97% of AXA3, p<0.001) and 91% of fenestrated/branched endovascular repair (F/BEVAR) procedures were conducted from the left. A ≥12F internal diameter (ID) sheath was used in 49% of procedures. Open conversion rate was 1%, no major vascular complications occurred, and only one major non-vascular complication was recorded. Primary closure failure occurred in 18 AXA1 (11%) and 32 AXA3 accesses (13%), treated by covered (8.3%) or bare-metal (2.7%) stenting. Bailout stent patency was 100% at median follow-up of 12 months, with 6 of 6 stents still patent after >36 months of follow-up. Stroke rate was 4.4%. An introducer sheath >12F was independently associated with both access complications (p<0.001) and stroke (p=0.005), while a right-side access was associated with stroke only (p=0.034). Even after adjustment for covariates, AXA1 versus AXA3 showed an equal success rate (odds ratio [OR]=0.537, 95% confidence interval [CI]=0.011-1.22 for AXA3, p=0.104). The combination of AXA3 and a >10F introducer sheath provided worse outcomes compared with >10F sheaths through AXA1 (OR for success=0.367, 95% CI=0.176-0.767, p=0.008). This was not confirmed for >12F sheaths, associated with similar outcomes (p=0.31 AXA 1 vs AXA 3). CONCLUSION Major local complications with the percutaneous axillary approach and ≤12F sheaths are infrequent and solvable by complementary endovascular interventions. Stroke risk remains an issue. First and third AXA segments are both amenable for access with good results, but larger sheaths (12F) perform better in AXA1. CLINICAL IMPACT Percutaneous access with vascular closure devices at the first or third axillary artery (AXA) segments during aortic procedures is burdened by a negligible risk of open conversion. Local complications with the percutaneous axillary approach are infrequent and solvable by complementary endovascular interventions. First and third AXA segments are both amenable to access with excellent results, but larger sheaths (12F) perform better in the wider first AXA segment. In this setting, bailout stenting does not appear to be associated with mid-term stent occlusion.

Abstract
Introduction Endovascular repair using off-the-shelf endografts is a viable solution in patients with ruptured or symptomatic complex aortic aneurysms. This analysis aimed to present the peri-operative and follow-up outcomes in urgent and emergent cases managed with the t-Branch multibranched thoracoabdominal endograft. Methods Prospectively collected data from all consecutive urgent and emergent cases managed in two aortic centers between January 1st, 2014, to November 30th, 2022, using the t-Branch device (Cook Medical Inc., Bjaeverskov, Denmark) were analyzed. Patients presenting with ruptured aortic complex aneurysms were characterized as emergent and patients with aneurysms >90 mm of diameter, or symptomatic aneurysms were characterized as urgent. Technical success, 30-day mortality, major adverse events (MAE) and spinal cord ischemia (SCI) rates were assessed. Results 225 patients (36.5% females, 72.5 ± 2.8 years) were included; 73.0% were urgent. The mean aneurysm diameter was 109 ± 3.9 mm and 44.4% were type I-III TAAAs. Females (p = .03), para-renal aneurysms (p = .02) and ASA score IV (p < .001) were more common in emergent cases. Technical success was 97.8%. Thirty-day mortality and MAE rates were 17.8% and 30.6%, respectively. SCI rate was 14.7%, (4.8% paraplegia rate) with 22.2% of patients receiving prophylactic cerebrospinal drainage. Thirty-day mortality (13.3% vs. 26.7%, p = .04) and MAE (26.0% vs. 43.0%, p = .02) were more common among emergent cases while technical success (97.6% vs. 98.3%, p = .9), and SCI (13.3% vs. 18.3%, p = .4) were similar. Survival at 12-months was 83.5% (SE 5.9%) for the urgent and 77.1% (SE 8.2%) for the emergent group (log rank, p = 0.96). Conclusion T-Branch represents an effective and safe solution for the management of urgent and emergent cases with complex aortic aneurysms, with high technical success, promising early mortality and SCI rates.

Abstract
PURPOSE To describe the technique of transvenous access for emergent endovascular repair of thoracic and thoracoabdominal aneurysms exemplified with 2 cases. TECHNIQUE Transvenous access to the aorta is described as an alternative access method to deliver aortic endografts in emergency situations. A 68-year-old female patient with severely compromised iliac and subclavian artery access was treated for a ruptured extent V thoraco-abdominal aortic aneurysm with a t-Branch (Cook Medical, Bjaeverskov, Denmark) delivered through a transcaval access. To avoid severe aortocaval shunting a balloon-expandable covered stent was deployed through a carotid access due to severe bilateral subclavian ostial stenosis. A 71-year-old man with an acute type B aortic dissection and bilateral narrow long-segment stenting of the iliac arteries was treated with a physician-modified thoracic endovascular aortic repair using an arteriovenous fenestration created at the level of the common iliac artery. We describe the access creation by fenestration using a transseptal needle. CONCLUSION Transvenous access for thoracic and thoraco-abdominal aortic aneurysm repair is safe and feasible in selected emergent cases. CLINICAL IMPACT A transvenous approach may be helpful in selected patients when an endovascular repair needs to be performed but no arterial femoral access is available. This approach proved to be feasible even with large-bore introducer sheaths, taking its place in the armamentarium of the vascular surgeon for emergent complex endovascular aortic repairs.

Abstract
Acute complicated type B aortic dissection is increasingly treated with endovascular techniques to manage contained rupture or end-organ malperfusion. Most cases of malperfusion occur during the acute phase of the dissection. We report a case of a patient treated for late presentation of lower body malperfusion 4 years after successful endovascular intervention for contained rupture of an acute type B dissection. The anatomic complexity required multiple staged procedures culminating in endovascular repair of the paravisceral aorta with an off-the-shelf four-vessel inner-branched endograft, used for the first time, to the best of our knowledge, in North America in the present case. The patient involved provided written informed consent for the report of his case details and imaging studies.

Abstract
OBJECTIVE To assess branch vessel outcomes after endovascular repair of complex aortic aneurysms analyzing possible factors influencing early and long-term results. METHODS The Italian Multicentre Fenestrated and Branched registry enrolled 596 consecutive patients treated with fenestrated and branched endografts for complex aortic disease from January 2008 to December 2019 by four Italian academic centers. The primary end points of the study were technical success (defined as target visceral vessel [TVV] patency and absence of bridging device-related endoleak at final intraoperative control), and freedom from TVV instability (defined as the combined results of type IC/IIIC endoleaks and patency loss) during follow-up. Secondary end points were overall survival and TVV-related reinterventions. RESULTS We excluded 591 patients (3 patients with a surgical debranching and 2 patients who died before completion from the study cohort) were treated for a total of 1991 visceral vessels targeted by either a directional branch or a fenestration. The overall technical success rate was 98.4%. Failure was related to the use of an off-the-shelf (OTS) device (custom-made device vs OTS, HR, 0.220; P = .007) and a preoperative TVV stenosis of >50% (HR, 12.460; P < .001). The mean follow-up time was 25.1 months (interquartile range, 3-39 months). The overall estimated survival rates were 87%, 77.4%, and 67.8% at 1, 3, and 5 years, respectively (standard error [SE], 0.015, 0.022, and 0.032). During follow-up, TVV branch instability was observed in 91 vessels (5%): 48 type IC/IIIC endoleaks (2.6%) and 43 stenoses-thromboses (2.4%). The extent of aneurysm disease (thoracoabdominal aortic aneurysm [TAAA] types I-III vs TAAA type IV/juxtarenal aortic aneurysm/pararenal aortic aneurysm) was the only independent predictor for developing a TVV-related type IC/IIIC endoleak (HR, 3.899; 95% confidence interval [CI]:, 1.924-7.900; P < .001). Risk of patency loss was independently associated with branch configuration (HR, 8.883; P < .001; 95% CI, 3.750-21.043) and renal arteries (HR, 2.848; P = .030; 95% CI, 1.108-7.319). Estimated rates at 1, 3, and 5 years of freedom from TVV instability and freedom from TVV-related reintervention were 96.6%, 93.8%, and 90% (SE, 0.005, 0.007, and 0.014) and 97.4%, 95.0%, and 91.6% (SE, 0.004, 0.007, and 0.013), respectively. CONCLUSIONS Intraoperative failure to bridge a TVV was associated with a preoperative TVV stenosis of >50% and the use of OTS devices. Midterm outcomes were satisfying, with an estimated 5-year freedom from TVV instability and reintervention of 90.0% and 91.6%, respectively. During follow-up, the larger extent of aneurysm disease was associated with an increased risk of TVV-related endoleaks, whereas a branch configuration and renal arteries were more prone to patency loss.

Fenestrated Physician-Modified Endografts for Preservation of Main and Accessory Renal Arteries in Juxtarenal Aortic Aneurysms. J Clin Med 2023; 12:4708. [PMID: 37510822 PMCID: PMC10416159 DOI: 10.3390/jcm12144708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 07/09/2023] [Accepted: 07/13/2023] [Indexed: 07/30/2023] Open
Abstract
BACKGROUND There is a paucity of reporting outcomes of complex aortic aneurysm treatment such as juxtarenal abdominal aortic aneurysms, where additional techniques to preserve renal artery perfusion are required. METHODS Retrospective analysis of consecutive patients who underwent emergent and elective aortic repair with fenestrated PMEGs between March 2019 and January 2023. Endpoints were technical success, reinterventions, secondary reinterventions and target vessel patency. RESULTS Forty-seven target vessels in 37 patients (23 male, median age 75 years) were targeted, of which 44 were renal arteries (RAs) with a mean diameter of 5.4 ± 1.0 mm. Thirteen were accessory RAs and six had a diameter ≤ 4 mm. Technical success rate was 87% overall; 97% for main and 62% for accessory RAs respectively. Target vessel patency and freedom from secondary reintervention was 100% and 97% at 30 days and 96% and 91% at one year, respectively. There was no 30-day mortality. CONCLUSION Fenestrated physician-modified endografts are safe and effective for the treatment of patients with juxtarenal abdominal aortic aneurysms when incorporating main renal arteries. Limited technical success may be expected when targeting accessory renal arteries, especially when small in diameter. Long-term follow-up is needed to confirm durability of PMEGs for renal artery preservation.

Abstract
OBJECTIVE The use of steerable sheaths to allow total transfemoral access (TFA) of branched endovascular repair (BEVAR) of thoracoabdominal aortic aneurysms has been proposed as an alternative to upper extremity access (UEA); however, multicenter results from high-volume aortic centers are lacking. MATERIALS AND METHODS The Total Transfemoral Branched Endovascular Thoracoabdominal Aortic Repair (TORCH2) study is a physician-initiated, national, multicenter, retrospective, observational registry (Clinicaltrials.gov identifier: NCT04930172) of patients undergoing BEVAR with a TFA for the cannulation of reno-visceral target vessels (TV). The study endpoints, classified according to Society for Vascular Surgery reporting standards, were (1) technical success; (2) 30-day peri-operative major adverse events; (3) 30-day and midterm clinical success; (4) 30-day and midterm branch instability and TV-related adverse events (reinterventions, type I/III endoleaks). RESULTS Sixty-eight patients (42 males; median age: 72 years) were treated through a TFA. All the centers included their entire experience with TFA: 18 (26%) used a homemade steerable sheath, and in 28 cases (41%), a stabilizing guidewire was employed. Steerable technical success was achieved in 66 patients (97%) with an overall in-hospital mortality of 6 patients (9%, 3 elective cases [3/58, 5%] and 3 urgent/emergent cases [3/12, 25%]) and major adverse event rate of 18% (12 patients). Overall, 257 bridging stents were implanted; of these, 225 (88%) were balloon-expandable and 32 (12%) were self-expanding. No strokes were observed among the patient completing the procedure from a TFA. One patient (2%) who failed to be treated completely from a TFA and needed a bailout UEA suffered an ischemic stroke on postoperative day 2. There were 10 (15%) major access-site complications. At 1-year follow-up, overall survival was 80%, and the rate of branch instability was 6%. CONCLUSIONS A TFA for TV cannulation is a safe and feasible option with high technical success preventing the stroke risk of UEA. Primary patency at midterm seems comparable to historical controls, and future larger studies will be needed to assess potential differences with alternative options. CLINICAL IMPACT Using a transfemoral approach for retrograde cannulation of reno-visceral branches is feasiable, safe and effective, thereby representing a reliable alternative for BEVAR interventions.

Abstract
OBJECTIVE The aim of this study was to investigate the early outcomes of a novel off the shelf pre-loaded inner branched thoraco-abdominal endograft (E-nside) in the treatment of aortic pathologies. METHODS Data from a physician initiated national multicentre registry on patients treated with the E-nside endograft, were prospectively collected and analysed. Pre-operative clinical and anatomical characteristics, procedural data, and early outcomes (90 days) were recorded in a dedicated electronic data capture system. The primary endpoint was technical success. Secondary endpoints were early mortality (90 days), procedural metrics, target vessel patency, endoleak rate, and major adverse events (MAEs) at 90 days. RESULTS In total, 116 patients from 31 Italian centres were included. Mean ± standard deviation (SD) patient age was 73 ± 8 years and 76 (65.5%) were male. Aortic pathologies included degenerative aneurysm in 98 (84.5%), post-dissection aneurysm in five (4.3%), pseudoaneurysm in six (5.2%), penetrating aortic ulcer or intramural haematoma in four (3.4%), and subacute dissection in three (2.6%). Mean ± SD aneurysm diameter was 66 ± 17 mm; aneurysm extent was Crawford I - III in 55 (50.4%), IV in 21 (19.2%), pararenal in 29 (26.7%), and juxtarenal in four (3.7%). The procedure setting was urgent in 25 (21.5%) patients. Median procedural time was 240 minutes (interquartile range [IQR] 195, 303), with a median contrast volume of 175 mL (IQR 120, 235). The endograft's technical success rate was 98.2% and the 90 day mortality rate was 5.2% (n = 6; 2.1% for elective repair and 16% for urgent repair). The 90-days cumulative MAE rate was 24.1% (n = 28). At 90 days, there were 10 (2.3%) target vessel related events (nine occlusions and one type IC endoleak) and one type 1A endoleak requiring re-intervention. CONCLUSION In this real life, non-sponsored registry, the E-nside endograft was used for the treatment of a broad spectrum of aortic pathologies, including urgent cases and different anatomies. The results showed excellent technical implantation safety and efficacy, as well as early outcomes. Longer term follow up is needed to better define the clinical role of this novel endograft.

Abstract
For a long time, parallel grafting, physician-modified endografts, and, more recently, in situ fenestration were the only go-to endovascular options for ruptured thoracoabdominal aortic aneurysm, offered mixed results, and depended mainly on the operator's and center's experience. As custom-made devices have become an established endovascular treatment option for elective thoracoabdominal aortic aneurysm, they are not a viable option in the emergency setting, as endograft production can take up to 4 months. The development of off-the-shelf (OTS) multibranched devices with a standardized configuration has allowed the treatment of ruptured thoracoabdominal aortic aneurysm with emergent branched endovascular procedures. The Zenith t-Branch device (Cook Medical) was the first readily available graft outside the United States to receive the CE mark (in 2012) and is currently the most studied device for those indications. A new device, the E-nside thoracoabdominal branch endoprosthesis OTS multibranched endograft (Artivion), has been made commercially available, and the GORE EXCLUDER thoracoabdominal branch endoprosthesis OTS multibranched endograft (W. L. Gore and Associates) is expected to be released in 2023. Due to the lack of guidelines on ruptured thoracoabdominal aortic aneurysm, this review summarizes the available treatment options (ie, parallel grafts, physician-modified endografts, in situ fenestrations, and OTS multibranched devices), compares the indications and contraindications, and points out the evidence gaps that should be filled in the next decade.

Eur J Vasc Endovasc Surg 2023; 65:720-727.

Abstract
OBJECTIVE Aortic endografting and antegrade in situ laser fenestration of visceral arteries (LFEVAR) may be considered as an alternative to open surgery for the emergency repair of complex abdominal aortic aneurysms (AAA) in fragile patients. The aim of this article was to evaluate the midterm results of LFEVAR performed with polyester endografts. METHODS From August 2015 to December 2020, all consecutive LFEVAR performed for non-deferrable treatment of complex AAA were analysed. Polyester endografts were deployed and subsequently fenestrated using an atherectomy laser probe; the fenestrations were enlarged using cutting and semicompliant balloons before implantation of balloon expandable bridging stents into the target vessels. Prospectively collected midterm survival, patency, and re-intervention rates were analysed. RESULTS Forty four procedures were performed for 11 type 1a endoleaks, five thoraco-abdominal aneurysms, 20 pararenal aneurysms, four segmental renal artery (RA) preservations, three anastomotic aneurysms, and one aortic dissection. One hundred and eight laser fenestrations were performed (26 for the superior mesenteric artery [SMA], 13 for the coeliac trunk, 33 and 31 for the right and left RA, respectively). The median ischaemia duration was 7, 48, 48, and 45 minutes, respectively. The technical success rate was 97%, with no open surgical conversions. The 30 day mortality was 4.5% (n = 2). No spinal cord ischaemia events were observed nor early stent related complications. Kaplan-Meier overall survival at two years was 73%, the aortic related re-intervention free survival was 70%, and the stent related re-intervention free survival was 90.6%. Four target vessel thromboses were detected, of which three were rescued. Three type IIIc endoleaks, one RA false aneurysm, and one SMA stenosis, required re-intervention during a median follow up of 24.7 months. CONCLUSION Antegrade LFEVAR is feasible, safe, and provides satisfactory early and midterm outcomes for non-deferrable treatment of aortic pathologies involving the visceral segment. Long term data are mandatory to confirm the usefulness of this promising off label technique.

Additional Aortic Coverage With an Off The Shelf, Multibranched Endograft Compared With Custom Made Devices For Endovascular Repair of Pararenal Abdominal Aortic Aneurysms. Eur J Vasc Endovasc Surg 2023; 65:710-718.

Abstract
OBJECTIVE Pararenal abdominal aortic aneurysms (p-AAA) require complex endovascular aortic repair or open surgical repair with suprarenal clamping. Custom made devices (CMD), including fenestrated and branched endovascular aortic repair (F/B-EVAR) or off the shelf (OTS) multibranched devices, are available treatment options. The aim of this study was to determine the additional healthy aortic coverage using an OTS multibranched endograft vs. a CMD for the treatment of p-AAAs. METHODS This was a retrospective single centre analysis of prospectively collected data. Consecutive patients with p-AAAs requiring a proximal landing zone above the coeliac artery (CA), planned and treated with CMDs (Zenith Fenestrated) between January 2017 and December 2021 were included in this study. Treatment with supracoeliac coverage using available OTS multibranched devices was simulated using available pre-operative images: T-Branch; E-nside; and TAMBE. Study endpoints included the need for additional proximal aortic coverage, and the number of the segmental arteries additionally covered proximally from the CA for OTS devices compared with CMDs. RESULTS Eighty three patients with p-AAAs were treated with CMDs (all FEVAR), including juxtarenal AAAs (n = 46; 56%), suprarenal AAAs (n = 20; 24%), and short neck AAAs (n = 17; 20%). In this study, treatment with 249 (3 × 83) OTS endografts was simulated. When compared with CMDs, OTS devices required a mean of 74 ± 19 mm of additional proximal healthy aortic coverage from the CA (CMD: 33 ± 19 mm vs. OTS: 108 ± 6 mm; p ≤ .001), as well as an average sacrifice of 2.5 additional segmental arteries (CMD: 1.3 ± 0.8 vs. OTS: 3.8 ± 0.9; p ≤ .001). In 94% of patients, at least one of the available multibranched endografts could have been implanted in accordance with instructions for use. CONCLUSION Despite not requiring customisation time, OTS endografts for the treatment of p-AAA lead to more extensive healthy aortic coverage, as well as an average sacrifice of 2.5 additional segmental arteries, compared with CMDs. When compared with OTS devices, CMDs appear to limit the extent of unnecessary aortic coverage and the theoretical subsequent risk of spinal cord ischaemia.

Abstract
OBJECTIVE To investigate access failure (AF) and stroke rates of aortic procedures performed with upper extremity access (UEA), and compare results of open surgical vs. percutaneous UEA techniques with closure devices. METHODS A physician initiated, multicentre, ambispective, observational registry (SUPERAXA - NCT04589962) was carried out of patients undergoing aortic procedures requiring UEA, including transcatheter aortic valve replacement, aortic arch, and thoraco-abdominal aortic endovascular repair, pararenal parallel grafts, renovisceral and iliac vessel repair. Only vascular procedures performed with an open surgical or percutaneous (with a suture mediated vessel closure device) UEA were analysed. Risk factors and endpoints were classified according to the Society for Vascular Surgery and VARC-3 (Valve Academic Research Consortium) reporting standards. A logistic regression model was used to identify AF and stroke risk predictors, and propensity matching was employed to compare the UEA closure techniques. RESULTS Sixteen centres registered 1 098 patients (806 men [73.4%]; median age 74 years, interquartile range 69 - 79 years) undergoing vascular procedures using open surgical (76%) or percutaneous (24%) UEA. Overall AF and stroke rates were 6.8% and 3.0%, respectively. Independent predictors of AF by multivariable analysis included pacemaker ipsilateral to the access (odds ratio [OR] 3.8, 95% confidence interval [CI] 1.2 - 12.1; p = .026), branched and fenestrated procedure (OR 3.4, 95% CI 1.2 - 9.6; p = .019) and introducer internal diameter ≥ 14 F (OR 6.6, 95% CI 2.1 - 20.7; p = .001). Stroke was associated with female sex (OR 3.4, 95% CI 1.3 - 9.0; p = .013), vessel diameter > 7 mm (OR 3.9, 95% CI 1.1 - 13.8; p = .037), and aortic arch procedure (OR 7.3, 95% CI 1.7 - 31.1; p = .007). After 1:1 propensity matching, there was no difference between open surgical and percutaneous cohorts. However, a statistically significantly higher number of adjunctive endovascular procedures was recorded in the percutaneous cohort (p < .001). CONCLUSION AF and stroke rates during complex aortic procedures employing UEA are non-negligible. Therefore, selective use of UEA is warranted. Percutaneous access with vessel closure devices is associated with similar complication rates, but more adjunctive endovascular procedures are required to avoid surgical exposure.

J Vasc Surg 2023; 77:374-385.e4. [PMID: 36356675 DOI: 10.1016/j.jvs.2022.09.019] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 09/13/2022] [Accepted: 09/19/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVE There is paucity of data on the durability of physician modified endografts (PMEGs) for complex abdominal (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs) despite widespread use. The aim of this study was to evaluate and compare the early and long-term outcomes of fenestrated-branched endovascular aortic repair (FB-EVAR) for CAAAs and TAAAs using PMEGs. METHODS We reviewed clinical data and outcomes of patients treated by FB-EVAR using PMEGs for CAAAs (defined as short-neck infrarenal, juxtarenal, and pararenal AAAs) and TAAAs between 2007 and 2019. All patients were treated by a dedicated team with extensive manufactured device experience. Endpoints included 30-day mortality and major adverse events, patient survival and freedom from aortic-related mortality (ARM), freedom from secondary intervention, target artery (TA) patency, and freedom from TA endoleak and TA instability. RESULTS Of 645 patients undergoing FB-EVAR, 156 patients (24%) treated with PMEG (121 males; mean age, 75 ± 8 years) were included. There were 89 CAAAs, 33 extent IV TAAAs and 34 extent I to III TAAAs. A total of 452 renal-mesenteric targets (3.1 ± 1.0 vessels/patient) were incorporated. Patients with TAAAs had significantly (P < .05) larger aneurysms (73 ± 11 vs 68 ± 14 mm), more TAs incorporated (3.4 ± 0.9 vs 2.8 ± 1.0), and more often had previous aortic repair (54% vs 27%). Technical success was higher in patients treated for CAAAs (99% vs 91%; P = .04). Thirty-day and/or in-hospital mortality was 5.7% and was significantly lower for CAAAs compared with TAAAs (2% vs 10%; P = .04), with three of nine early mortalities (33%) among patients treated emergently. After a mean follow-up of 49 ± 38 months, there were 12 aortic-related deaths (7.6%), including nine early deaths (5.7%) from perioperative complications and three late deaths (1.9%) from rupture. At 5 years, patient survival was 41%. Patients treated for CAAAs had higher 5-year freedom from ARM (P = .016), TA instability (P = .05), TA endoleak (P = .01), and TA secondary interventions (P = .05) with a higher, but non-significant, freedom from sac enlargement ≥5 mm (P = .11). Primary and secondary TA patency was 91% ± 2% and 99% ± 1%, respectively. Sac regression ≥5 mm occurred in 67 patients (43%) and was associated with increased survival (hazard ratio, 0.54; 95% confidence interval, 0.37-0.80) compared with those without sac regression. CONCLUSIONS FB-EVAR using PMEGs was performed with acceptable long-term outcomes. Overall patient survival was low due to significant underlying comorbidities. Patients treated for CAAAs had higher freedom from ARM, TA instability, TA endoleak, TA secondary interventions, and a trend towards higher freedom from sac enlargement compared with patients treated for TAAAs. Sac regression was associated with improved patient survival.

Abstract
Complex endovascular therapy of the aorta with fenestrated and branched endografts plays an essential role in modern vascular medicine. Innovative solutions for demanding aortic pathologies are therefore being constantly developed by the medical industry. The aim of this manuscript is to illustrate the growing importance of the inner branches in complex aortic repair and to show the advantages and limits of this technique with an overview of the current literature. The inner branches (iBEVAR) were therefore compared to the standard treatment options (fenestrations; [FEVAR], outer branches [BEVAR]) and the technical advantages of all platforms were evaluated. The widespread use of iBEVAR in the aortic arch stands in contrast to the thoracoabdominal aorta, which is mirrored by the scarce evidence for the thoracoabdominal inner branches. The published experience is based on smaller retrospective studies with a 1-year follow-up. The E-nside (Artivion, Hechingen, Germany) thoracoabdominal off-the-shelf inner-branch-based endograft was released 2 years ago. Its widespread deployment may increase the use of the inner branches in the thoracoabdominal aorta. Moreover, an ongoing industry-funded registry may provide new insights into the long-term durability of this innovative technique.

Abstract
Purpose To investigate the safety and efficacy of total endovascular repair for thoracoabdominal aortic aneurysms (TAAAs) with fenestrated and branched stent-grafts. Methods The MEDLINE, EMBASE, and Cochrane databases were searched between January 2001 and December 2021 to identify literature relevant to the use of fenestrated and branched endografts for the treatment of TAAAs. Studies with <4 cases and those on juxtarenal or pararenal aortic aneurysms were excluded. Meta-analyses were conducted to evaluate spinal cord ischemia (SCI), irreversible SCI, renal insufficiency, dialysis, endoleak, reintervention, target vessel patency, 30-day mortality and overall mortality. Fourteen studies comprising 1,114 patients (mean age 72.42 years, 847 men) were selected. The mean TAAA diameter was 67 mm. The Crawford TAAA classification was type I-III in 759 cases, type IV in 344 cases, and type V in 10 cases. Outcomes of the meta-analysis are reported as proportions and 95% confidence intervals (CIs). Results The pooled rates for 30-day mortality and overall mortality were 6% and 18%, respectively. The pooled rate for technical success was 94% (95% CI, 93–96%), for SCI was 8% (95% CI, 7–10%), for irreversible SCI was 6% (95% CI, 4–7%), for reversible SCI was 5% (95% CI, 4–6%), for reversible SCI was 2% (95% CI, 2–3%), for renal insufficiency was 7% (95% CI, 5–10%), for dialysis was 3% (95% CI, 2–4%), for target vessel patency was 98% (95% CI, 97–99%), and for reintervention was 15% (95% CI, 9–24%). Conclusion Fenestrated and branched endografts for the treatment of TAAAs are safe and effective with acceptable early results. Lifelong regular follow-up and additional prospective studies are necessary to substantiate whether this technique is valid.

Abstract
OBJECTIVE To evaluate the technique and outcomes of intentional occlusion of directional branches (DBs) using endovascular plugs during branched endovascular aortic repair using off-the-shelf Zenith t-Branch thoracoabdominal (TAAA) stent grafts. METHODS We reviewed the clinical data and outcomes of all consecutive patients treated by branched endovascular aortic repair using off-the-shelf Zenith t-Branch TAAA stent-graft (Cook Medical, Bloomington, Ind) in seven academic centers from 2013 to 2019. All patients had at least one DB intentionally occluded using extension of the branch with balloon or self-expandable covered stent, followed by placement of endovascular plugs. Intentional occlusion was indicated in patients with variations in the normal four-vessel renal-mesenteric anatomy, pre-existing dialysis, or in those who failed catheterization of a target vessel. End points were 30-day/in-hospital mortality, major adverse events, secondary interventions, target artery (TA) patency, TA instability, and patient survival. RESULTS There were 100 patients, 65 male and 35 female, with median age of 71 years (interquartile range [IQR], 66-75 years). Of these, 31 patients (31%) had urgent/emergent operations for symptomatic/contained ruptured aneurysms. The median aneurysm diameter was 72 mm (IQR, 61-85 mm). A total of 290 renal-mesenteric arteries were incorporated with a median of three (IQR, 3-3) vessels/patient. Indications for DB occlusion were less than four suitable renal-mesenteric targets in 84 patients or pre-existing dialysis and inability to catheterize a target vessel in eight patients each. There were 110 DBs occluded by vascular plugs, including 48 celiac axis, one superior mesenteric artery, and 61 renal DBs. Thirty-day/in-hospital mortality was 10%, including 9% for elective and 13% for urgent/emergent procedures. Major adverse events occurred in 44 patients (44%), including acute kidney injury in 19 patients (19%), estimated blood loss >1 L in 12 patients (12%), respiratory failure and new onset dialysis in six patients (6%) each, bowel ischemia in five patients (5%), and myocardial infarction and paraplegia in two patients (2%) each. The median follow-up was 5 months (range, 1-13 months). Eighteen patients (18%) required secondary interventions, none for problems related to the occluded DB. There were no endoleaks related to the occluded DB. At 2 years, primary and secondary patency and freedom from TA instability were 93% ± 3%, 97% ± 2%, and 91% ± 4%, respectively. Freedom from secondary interventions and patient survival were 75% ± 6% and 63% ± 7%, respectively. CONCLUSIONS Intentional occlusion of DBs using endovascular plugs allows versatile use of a four-vessel off-the-shelf multi-branched TAAA stent graft in patients with variations in the normal renal and mesenteric anatomy or when technical difficulties prevent successful target vessel stenting. There were no endoleaks or secondary interventions associated with the occluded DB.

Abstract
INTRODUCTION The multibranched off-the-shelf stent graft is a promising treatment option for thoracoabdominal aortic aneurysm (TAAA). A commercially available, multibranched, off-the-shelf endograft called the t-Branch stent graft has demonstrated favourable midterm outcomes. Another two investigational off-the-shelf endografts, the GORE EXCLUDER Thoracoabdominal Branch Endoprosthesis and E-nside multibranch stent graft system, are still being developed. However, these three endografts have an unsatisfactory anatomic feasibility rate in patients with TAAA. Based on the concept of Guo's renovisceral artery reconstruction-1, a novel, multibranched, off-the-shelf endograft with different configurations has been developed. METHODS AND ANALYSIS This prospective, multicentre, single-arm, cohort study will enrol 73 patients with TAAA. Preoperative and postoperative clinical data, as well as CT angiography images at each follow-up timepoint, will be analysed to evaluate the safety and efficacy of this novel, multibranched, off-the-shelf endograft for the treatment of TAAA. The primary safety end point is the major adverse event rate within 30 days after index endovascular aortic repair, including all-cause death, hepatic failure, bowel necrosis, renal failure, stroke, permanent paraplegia, cardiac infarction and respiratory failure. The primary efficacy end point is the successful treatment rate within 12 months after procedure, which is a composite of immediate technical success and no secondary surgical intervention related to TAAA within 12 months after the procedure. ETHICS AND DISSEMINATION The protocol has been reviewed and approved by the ethics committee of Chinese PLA General Hospital (reference number: 2021-NO.-007) and each participating hospital. The findings of this study will be disseminated through conference presentations, peer-reviewed journal publications and social media. TRIAL REGISTRATION NUMBER NCT05054985.

Abstract
OBJECTIVES Our goal was to report outcomes of the endovascular repair of urgent thoracoabdominal aortic aneurysms (TAAAs) using the Cook Zenith t-Branch off-the-shelf multibranched endograft. METHODS Between 2010 and 2020, we collected patients with TAAAs who received an urgent endovascular repair using the Cook Zenith t-Branch (had a rupture, symptoms or diameter >80 mm). Thirty-day mortality, spinal cord ischaemia (SCI) and clinical success were assessed as early outcomes. Freedom from reintervention, target visceral vessel patency and survival were considered during follow-up. RESULTS Sixty-five cases were managed using the Cook Zenith t-Branch for 27 (42%) TAAA ruptures, 8 (12%) symptomatic TAAAs and 30 (46%) asymptomatic TAAAs with a diameter >80 mm. Crawford's extent I-II-III and IV were noted in 54 (83%) and 11 (17%), respectively. Eleven (17%) patients had SCI with 3 (5%) cases of permanent paraplegia. Postoperative dialysis (P = 0.04) and ruptured TAAAs (P = 0.05) were associated with SCI. Sixteen (25%) patients had reinterventions within the first 30 days postoperatively. The 30-day mortality was 14% (9). Ruptured TAAAs (P = 0.05) and technical failures (P = 0.01) were correlated with in-hospital mortality. Clinical success was 78% (51 patients). The mean follow-up was 18 ± 14 months. Survival at 24 months was 47% with no late TAAA-related deaths. Patients with ruptured TAAAs had lower survival than those who did not have ruptured TAAAs (52% vs 60% at 1 year; P = 0.05). Target visceral vessel patency and freedom from reintervention at 24 months were 89% and 60%, respectively. CONCLUSIONS An off-the-shelf multibranched endograft is safe and effective for treating urgent TAAAs. Postoperative SCI and 30-day mortality are satisfactory for this challenging clinical scenario. The early reintervention rate is not negligible. Midterm survival is low, especially in patients with a ruptured TAAA; therefore, accurate patient selection is mandatory.

Abstract
INTRODUCTION Treatment of complex abdominal and thoracoabdominal aortic aneurysms is challenging. Open surgical repair is a high-risk operation, especially in emergency cases. Endovascular aneurysm repair with a patient-specific custom-made stent graft in patients with symptomatic or ruptured complex aortic aneurysms is not possible, due to the manufacturing time required. In such cases, alternative endovascular techniques can be used. RESULTS The "off-the-shelf" and "surgeon-modified" stent grafts are valid options for the endovascular treatment of complex aneurysms in urgent and emergent patients. The former are standardised commercially manufactured fenestrated or branched stent grafts, which are available off-the-shelf with an anatomical feasibility in 50 - 80% of the patients. The "surgeon-modified" stent grafts refer to a technique, in which a commercially available stent graft is modified by the surgeon under sterile conditions directly before the implantation, in order to add the required fenestrations, scallops and/or branches. The modification takes approximately 60 - 120 min and haemodynamic stability of the patient is mandatory. Because of the off-label use of the commercial stent graft, detailed patient consent about the modification complications and risks should be performed whenever possible. A comparison of results on mortality and morbidity between "off-the-shelf" and "surgeon-modified" stent grafts has been published, although a direct comparison would be unfair for several reasons (different design, lack of extensive outcomes reports, long learning curve and different modification techniques). CONCLUSION The "surgeon-modified" and "off-the-shelf" fenestrated/branched stent grafts are used in the treatment of high-risk patients with symptomatic or contained ruptured complex aneurysms. The outcomes of the two techniques are good, although the long-term durability of the former should be further investigated.

Abstract
Treatment options for large or symptomatic complex aortic aneurysms that require urgent intervention remain limited. Patient factors and comorbidities often make open surgery unappealing, leading to increasing interest in endovascular solutions that can be employed in the urgent setting, such as off-the-shelf endografts. The E-nsideTM (Jotec GmbH, Hechingen, Germany) is a new off-the-shelf endograft with 4 pre-cannulated inner branches that has recently become available in Europe. We report the urgent treatment of 2 large complex aortic aneurysms using this device and discuss the benefits of this new technology. The E-nside off-the-shelf endograft with inner branches is a useful addition to our treatment options for complex aortic aneurysms, particularly those with a narrow aortic lumen. Pre-cannulation of branches provides consistent access to the branches and a readily available option for establishment of a through and through wire for added stability during cannulation and bridging stent-grafts placement. The design of inner branches provides flexibility during deployment of the endograft and cannulation of the target vessels in varied, challenging anatomies.
