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
INTRODUCTION Data on target vessel (TV)-related outcomes in patients managed with branched thoracic endovascular aortic repair (BTEVAR) are limited. This study aimed to present the TV-related outcomes of BTEVAR in patients managed for aortic arch pathologies at 30 days and during follow-up. METHODS A retrospective analysis of consecutive patients, managed between September 1, 2011, and June 30, 2022, with custom-made aortic arch endografts (Cook Medical, Bloomington, IN, USA), presenting at least one branch configuration, were eligible. Primary outcomes were technical success, TV-related patency, and reinterventions at 30 days. RESULTS In total, 255 TVs were revascularized using branches: 107 innominate arteries (IAs), 108 left common carotid arteries (LCCAs), and 40 left subclavian arteries (LSAs). Covered stents were used as bridging stents of which 10.2% were balloon expandable. Relining, using bare-metal stents (BMS), was performed in 14.0% of IAs, 35.2% of LCCAs, and 22.5% of LSAs. Technical success on case basis was 99.2%; no failure was related to unsuccessful TV bridging. At 30 day follow-up, no TV occlusion was detected. In 5.6% of cases, a type Ic or III endoleak, attributed to TVs, was recorded. Two patients needed early branch-related reintervention. The mean follow-up was 18.3±9.2 months. Freedom from TV instability was 94.6% (standard error [SE] 2.5%] at 12 months. No TV stenosis or occlusion was detected up to 48 months of follow-up. Freedom from TV-related reinterventions was 95.4% [SE 2.4%] at 12 months. CONCLUSION TV stenosis or occlusion in BTEVAR cases is rare and TV-related reinterventions and instability events are mainly attributed to type Ic and III endoleak formation. CLINICAL IMPACT Previous studies focusing on target vessel (TV) outcomes after endovascular aortic arch repair are limited. In this study, including 255 TVs revascularized using branched arch devices, bridging was performed with covered stents, of which 90% were self-expanding. Relining was at the discretion of the operator and was 14% for the innominate, 35.2% for the left common carotid and 22.5% for the left subclavian artery branches. No 30-day occlusion was detected. The freedom from TV instability was almost 95% at 12 months. TV instability and reintervention were mainly attributed to endoleaks type Ic and IIIc.

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
Aortic endograft evolution has altered our approach to treating patients with both standard and complex aortic disease. In particular, fenestrated and branched aortic endografts have allowed for the expansion of therapy to include those patients with extensive thoracoabdominal aortic aneurysms (TAAAs). The fenestrations and branches allow for the aortic endografts to achieve a seal in the proximal and distal aspects of the aorto-iliac tree, to exclude the aneurysm, while maintaining perfusion to the renal and visceral vessels. Historically, many of the grafts used for this purpose are custom made devices designed for a specific patient based on their preoperative computed tomography imaging. One downside to this approach is the time it takes to construct these grafts. Given this, much effort has been directed towards developing "off-the-shelf" grafts which may be applicable to many patients in an immediate-need bases. The Zenith T-Branch device offers an off-the-shelf graft with four directional branches. Its utilization is not applicable to all patients, but can be applied to many patients with TAAAs. Large reported series on outcomes for these devices is limited to centers in Europe as well as within the United States Aortic Research Consortium. While early outcomes appear excellent, long-term outcomes related to aneurysm exclusion, branch patency, and freedom from reintervention are needed and will be forthcoming.

Abstract
INTRODUCTION Endovascular aortic arch repair using multibranch devices has been applied in patients considered at high risk for open repair. The aim of this case series was to report the early outcomes in patients managed with a new design 3 branch arch custom-made device, including a retrograde left common carotid artery (LCCA) branch. METHODS The Preferred Reporting Of CaSe Series in Surgery (PROCESS) guidelines were followed. All consecutive patients undergoing endovascular repair of an aortic arch lesion with a custom-made triple-branch device, including a retrograde LCCA branch (Cook Medical, Bloomington, IN, USA), between October 27, 2022, and February 28, 2023, were included. The presence of an arch aneurysm (degenerative or post-dissection) with diameter ≥55 mm and high risk for a conventional open repair set the indication for treatment. The primary outcomes were technical success and mortality at 30 days. Early morbidity and reinterventions were considered as secondary outcomes. RESULTS Eight elective patients (87.5% men, mean age 72.3±27.0 years) were included. Five of them (62.5%) had undergone a previous ascending aorta repair of an acute type A aortic dissection. All patients were asymptomatic, except one, with left recurrent laryngeal nerve compression. The mean maximum aortic diameter was 70.4±21.0 mm. Percutaneous femoral and axillary access was used in all cases except three in which a cut down for right carotid access was performed. Technical success was 100%. Femoral access to the LCCA and implantation of the bridging stent was performed without technical challenges. No death nor cerebrovascular event was recorded during the 30 day follow-up. Five patients (62.5%) presented major complications, 3 related to access needing reintervention and the remaining related to congestive heart failure (CHF), which were managed successfully with medical treatment. Follow-up (range 1-4 month) was uneventful, except for one patient who presented a secondary type Ia endoleak. CONCLUSIONS According to our early experience, the presence of a retrograde branch facilitated the revascularization of the LCCA through femoral access, decreasing the risk of cerebrovascular morbidity. Further analyses with longer follow-up are needed to evaluate the safety and efficacy of the device. CLINICAL IMPACT Data arising mainly from the retrograde branch for the revascularization of the LSA are encouraging from a variety of devices. The premiminary experience with a triple-branched arch device, with a retrograde branche for the LSA but also for the LCCA, was associated with no 30 day mortality and 100% technical success.The device's design allowed swift catheterization and completion of the LCCA revascularization using femoral access exclusively.
