Endovascular repair of pararenal and thoracoabdominal aortic aneurysms with inner and outer off-the shelf-multibranched endografts. A systematic review and meta-analysis. J Vasc Surg 2024:S0741-5214(24)01713-0. [PMID: 39147287 DOI: 10.1016/j.jvs.2024.08.013] [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: 05/28/2024] [Revised: 08/03/2024] [Accepted: 08/08/2024] [Indexed: 08/17/2024]
Abstract
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 up to 12 weeks. During this awaiting period, the aortic related mortality is being increased. To overcome this limitation, off-the shelf standardized multibranched devices were launched in the market for the treatment of pararenal and thoracoabdominal aortic aneurysms (TAAA). Our aim was to systematically evaluate all the published studies of off-the shelf endografts for the treatment of pararenal and thoracoabdominal aortic aneurysms. METHODS We performed a systematic review to identify all the eligible studies that reported outcomes to the off-the-shelf with inner or outer multibranched devices and then conducted a qualitative synthesis and meta-analysis of the results. The main outcomes were technical success, mortality, target visceral vessel (TVV) instability, major adverse events and reintervention rate. We estimated pooled proportions and 95% confidence intervals (CIs). RESULTS A total of 1605 study titles were identified by the initial search strategy, of which 13 (8=t-Branch/ 3=E-nside/1=We-Flow/1=TAMBE) were considered eligible for inclusion in the meta-analysis. A total of 595 patients (70% male) were identified among the eligible studies. In terms of procedures, 64.4% were elective, 19.2% (13.4% outer-multibranched group (OMG); 6.1% inner-multibranched group (IMG) were emergent, and 16.4% (15.6% OMG; 0.8% IMG) were urgent. The pooled technical success was 92.1% (95%, CI, 83.8-96.4%) and 96.9% (95%, CI, 92.5-98.8%) for the outer- and inner-multibranched endograft, respectively. The pooled 30-day mortality was 10.4 % (95%, CI, 6.6-16.1%,) and 4.2% (95%, CI, 2.0-8.6%) for the outer and inner branched group respectively. The pooled 30-day and late TVV instability for the outer-branched group was 3.5% (95%, CI, 2.0-6.1%) and 6.2% (95%, CI, 4.7-8.0%) and for the inner branched group 10.4% (95%, CI, 4.5-22.5%) and 1.6% (95%, CI, 0.7-3.3%) respectively. CONCLUSIONS This pooled analysis indicated good technical success and mortality rate, for both devices despite the high rate of urgent procedures. Pararenal and thoracoabdominal aortic aneurysms can be safely treated using the included devices. However, further studies are required to draw additional conclusions for the inner group due to the small sample size.

Eur J Vasc Endovasc Surg 2024; 68:50-59. [PMID: 38636923 DOI: 10.1016/j.ejvs.2024.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 01/25/2024] [Accepted: 04/10/2024] [Indexed: 04/20/2024]
Abstract
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. RESULTS The study included 163 patients: 79 (307 target vessels) treated with E-nside and 84 (325 target vessels) with t-branch. Aneurysm extent was I - III in 91 patients (55.8%; 47% of E-nside and 66% of t-Branch) and IV in 72 patients (44.2%; 53% of E-nside and 34% of t-Branch) (p = .011). An adjunctive proximal thoracic endograft was used in 43% of E-nside vs. 69% of t-Branch (p < .001), with less frequent thoracic endografting (14% vs. 76%; p < .001) and shorter length of coverage (p = .024) in extent IV TAAA treated by E-nside. E-nside cases had shorter renal artery bridging lengths (66 ± 17 mm vs. 76 ± 20 mm; p < .010) and less frequent use of a distal bifurcated endograft (53% vs. 80%; p < .001). Comparing 30 day results, the mortality rate was 1% vs. 2% (p = .62), any MAE occurred in 18% vs. 21% (p = .55), the stroke rate was 3% vs. 0% (p = .23), and the elective spinal cord ischaemia rate was 5% vs. 8% (p = .40) for E-nside and t-Branch, respectively. At one year, freedom from target vessel instability was 96 ± 3% for E-nside and 95 ± 3% for t-Branch (p = .58), and freedom from endograft instability was 98 ± 2% vs. 97 ± 3% (p = .46), respectively. CONCLUSION Both off the shelf devices provided excellent early and one year results. The E-nside may require shorter thoracic aortic coverage and bridging length for the renal arteries, and less frequent implantation of a concomitant proximal thoracic or distal abdominal bifurcated endograft. However, these aspects did not determine significant differences in clinical outcomes.

Abstract
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. Secondary outcomes were spinal cord ischemia rate, stroke rate, major adverse events (MAE) as also branch instability at 12 months. RESULTS Of 185 patients enrolled in the INBREED, 64 (34.5%) were treated in a urgent setting and were included in the study. Reason for urgent repair was presence of aneurysm-related symptoms in 31 patients (48.4%), a contained rupture in eight (12.5%), and a large aneurysm >80 mm in 25 (39.1%). Extent of repair was I to III in 32 patients (50%) and IV in 32 (50%); 18 (28%) had a narrow (<25 mm) paravisceral aortic lumen. An adjunctive proximal thoracic endograft was deployed in 29 patients (45.3%); a distal bifurcated abdominal endograft was used in 33 (51.5%). Two hundred forty-nine target vessels (97.2%) were successfully incorporated through an inner branch from an upper arm (81.2%) or femoral (18.8%) access. A balloon expandable stent was used in 184 (75.7%) target vessels, a self-expandable stent in 59 (24.3%). Mean time for target vessel bridging was 39.9 ± 28.4 minutes per target vessel. Thirty-day cumulative major adverse event (MAE) rate was 28%, and mortality occurred in five patients (9.1%). There was one postoperative stroke (1.6%), and the spinal cord ischemia (SCI) rate was 8% (n = 5). For the 249 target vessels successfully incorporated through an inner branch, 1-year freedom from target vessel instability was 93% ± 3% after 1 year. CONCLUSIONS The E-nside represents a valid solution for the urgent treatment of TAAAs, including symptomatic and ruptured TAAAs, as well as large asymptomatic TAAAs that cannot wait for a custom-made device. The preloaded inner branches and available proximal and distal graft diameters might be useful in urgent settings and provided satisfactory early and 1-year results, in terms of both endograft and target vessel stability. Further studies are required to assess the clinical role of E-nside for urgent TAAA repair.

J Vasc Surg Cases Innov Tech 2024; 10:101491. [PMID: 38699664 PMCID: PMC11063593 DOI: 10.1016/j.jvscit.2024.101491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 03/12/2024] [Indexed: 05/05/2024] Open
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.

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.

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.

Abstract
OBJECTIVE The aim of this study was to investigate the outcomes of primary determinate and indeterminate target vessel endoleaks (TVELs) after fenestrated-branched endovascular aortic repair (F-BEVAR). METHODS We conducted a single-center retrospective study (2014-2023) on F-BEVAR for thoracoabdominal (TAAAs) or pararenal aortic aneurysms (PRAAs). TVELs were classified as "primary" if present at the first postoperative computed tomography angiogram. Endoleaks were defined "determinate" (dELs) if the cause (type Ic or IIIc) and implicated target vessel were identifiable and "indeterminate" (iELs) if contrast enhancement was detectable at the level of fenestrations/branches without any evident source. Endoleaks involving multiple inflows (type II and target vessels) were defined as "complex" (cELs). Endpoints were endoleak spontaneous resolution, 1-year aneurysm sac failure to regress (>5 mm diameter decrease), and 4-year endoleak-related secondary interventions. Kaplan-Meier estimates and Cox regression were used for the analysis. RESULTS There were 142 patients with JRAAs/PRAAs (n = 85; 60%) or TAAAs (n = 57; 40%), with 513 target arteries incorporated through a fenestration (n = 294; 57%) or directional branch (n = 219; 43%). Fifty-nine primary TVELs (12%) were identified in 35 patients (25%), a dEL in 20 patients (14%) and iEL in 15 (11%); 22 (15%) had a determinate or indeterminate cEL. Overall spontaneous resolution rate was 75% (95% confidence interval [CI], 51%-87%) at 4 years. cELs (odds ratio [OR], 5.00; 95% CI, 1.10-49.4; P < .001) and iELs after BEVAR (OR, 9.43; 95% CI, 3.41-56.4; P = .002) were more likely to persist >6 months, and persistent forms were associated with sac failure to regress at 1 year (OR, 1.72; 95% CI, 1.03-12.59; P = .040). Overall freedom from endoleak-related reinterventions was 85% (95% CI, 79%-92%) at 4 years, 92% (95% CI, 87%-97%) for those without primary TVELs and 62% (95% CI, 46%-84%) for those with any primary TVEL (P < .001). In particular, cELs (hazard ratio, 1.94; 95% CI, 1.4-18.81; P = .020) were associated with an increased need for reintervention. In case a secondary intervention was needed, iEL or cEL had an increased risk for multiple secondary procedures (hazard ratio, 2.67; 95% CI, 1.22-10.34; P = .034). CONCLUSIONS Primary TVELs are frequent after F-BEVAR, and a clear characterization of the endoleak source by computed tomography angiogram is not possible in 40% of patients. Most primary TVELs spontaneously resolve, but during follow-up, patients with any primary TVEL experience a worsened freedom from endoleak-related reinterventions that is mostly driven by persistence of cELs and post-BEVAR iELs. Multiple secondary procedures may be required in case of iELs or cELs.

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
OBJECTIVE To conduct a meta-analysis to assess the safety and efficacy of t-Branch off-the-shelf multibranched endograft for the treatment of thoracoabdominal aortic aneurysm (TAAA). DATA SOURCES PubMed, Embase, and Web of Science. REVIEW METHODS Online databases were searched from June 2012 to March 2023. The data were pooled together using a random-effects model of proportions. The outcomes overall included technical success, spinal cord ischemia, target vessel occlusion, type I or III endoleak, reintervention, early mortality (30-day), and mid-term outcomes. Subgroup meta-analyses and meta-regression were performed to explore variation among studies. RESULTS A total of 15 studies containing 1238 patients were included in the meta-analysis. The overall study quality assessment was found to be moderate to good. The pooled technical success was 97.0% (95% confidence interval [CI]=95.5-98.6, I2=53.01%, 1185/1238 cases, 15 studies). Overall, early mortality was 7.3% (95% CI=4.4-10.1, I2=74.48%, 124/1238 cases, 15 studies). Early spinal cord ischemia was 13.4% (95% CI=9.6-17.2, I2=67.24%, 160/1238 cases, 15 studies), and early type I or III endoleak was 6.0% (95% CI=3.4-8.5, I2=53.71%, 68/1032 cases, 9 studies). Mid-term outcomes showed target vessel occlusion was 4% (95% CI=1.4-6.5, I2=65.18%, 28/528 cases, 10 studies, 5-21.2 months), type I or III endoleak was 4.7% (95% CI=2-7.5, I2=49.74%, 38/512 cases, 10 studies, 5-21.2 months), reintervention was 11.2% (95% CI=8.1-14.3, I2=31.06%, 85/650 cases, 10 studies, 5-21.2 months), and pooled mortality was 13.9% (95% CI=7.2-20.7, I2=76.32%, 84/550 cases, 11 studies, 5-21.2 months). Meta-regression found a significant linear association between higher technical success and earlier publication year (p=0.014) and studies with anatomic inclusion criteria (p=0.037). Urgent patients (p=0.021) and later publication year (p=0.048) were significantly associated with higher early mortality. CONCLUSION The use of the off-the-shelf t-Branch multibranched endograft for elective or urgent endovascular TAAA repair is associated with high technical success rates and proved to be safe and effective at early and mid-term follow-up. However, the heterogeneity between the included studies is high, and prospective, randomized studies along with future larger studies with long-term follow-up are needed. CLINICAL IMPACT The Zenith t-Branch (Cook Medical, Bloomington, Ind) was approved as a commercially available device in Europe in June 2012. Although a decade has past, the outcomes of t-Branch have rarely been synthesized at the global level. This meta-analysis included 15 studies containing 1238 patients. The meta-analyses included technical success, major adverse events, reintervention, early mortality, and mid-term outcomes. The outcome was very meaningful and representative for the use of t-Branch. It is helpful for endovascular surgeons to make decisions on the treatment of TAAA patients.

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
Endovascular treatment of complex aortic aneurysms (cAAA) including thoracoabdominal aortic aneurysms is becoming more common. Most patients require custom made devices and until recently the off the shelf (OTS) options were limited. The aim of this manuscript was to describe a new inner branch OTS device and its clinical applications. A review of the current literature on the ENSIDE device from Artivion was performed and the authors' experience presented. The short outcomes of this particular OTS device are acceptable and the anatomical suitability on par with other similar devices. The preloaded configuration of the device can offer benefits in complex anatomy. New OTS devices for cAAA can provide treatment in emergent or urgent situations in many patients. Long term follow-up is needed and caution must be made against excessive use in less extensive aneurysms due to the risk of spinal cord ischemia.

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
We describe the feasibility of a technique for temporary aneurysm sac reperfusion after endovascular single-stage thoracoabdominal aortic aneurysm exclusion, to be used in the case of postoperative spinal cord ischemia. Two cases were treated for impending rupture of a thoracoabdominal aortic aneurysm. Before completion of sac exclusion, a supplementary buddy wire (V-18 control guidewire; Boston Scientific) was advanced in parallel fashion from the left percutaneous femoral access into the aneurysmal sac on the posterior aspect of the endograft. Distal aneurysm exclusion was completed using the main superstiff guidewire, and the femoral access was closed with a percutaneous closure device (ProGlide; Abbott) in standard fashion, leaving in place the sole V-18 guidewire, draped in sterile fashion. In the case of spinal cord ischemia, the "safe-line" can be rapidly used for spinal reperfusion after trans-sealing exchange with a 6F, 65-cm-long Destination sheath (Terumo) connected to a 6F introducer on the contralateral femoral artery.

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
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.
