Abstract
INTRODUCTION Blunt thoracic aortic injury (BTAI) represents one of the most devastating scenarios of vascular trauma which warrants prompt recognition with expedited management. Clinical manifestations of BTAI may not be straightforward to detect and may be misdiagnosed. Therefore, diagnosis of BTAI requires a high index of suspicion based on the mechanism of injury along with urgent transfer to centers with appropriate expertise and facilities. METHODS We provide an expert-based narrative review on endovascular treatment of BTAI highlighting indications, techniques, results, and challenges. RESULTS Multiple imaging modalities can be used including computed tomography angiography, transesophageal echocardiography, magnetic resonance imaging, and intravascular ultrasound. Whilst conservative pharmacological management can be a safe option in low-grade BTAI, thoracic endovascular aortic repair has become the gold-standard strategy in most cases, replacing open surgical repair. Nevertheless, it is important to account for patient demographics particularly age, severity of injury, choice of endograft including its type and size, and endovascular technique including landing zone and left subclavian artery revascularization. CONCLUSIONS Overall, TEVAR in BTAI has been shown to be an efficacious strategy with favorable early outcomes. In contrast, less is known on the long-term clinical outcomes of TEVAR in BTAI. Hence, despite the optimal early technical and clinical success rates, concerns remain about the need for long-term surveillance. The exact timing of follow-up and the integration of different modalities that can also investigate potential downstream cardiovascular effects remain hot topics for future research. Finally, industry should focus on developing more compliant endografts to improve the stiffness mismatch between the endograft and the aorta to optimize results.

Abstract
Background The triglyceride-glucose (TyG) index and triglyceride to high-density lipoprotein cholesterol (TG/HDL-c) ratio are both reliable surrogate indicator of insulin resistance and have been shown to be valuable in predicting various cardiovascular diseases. However, few studies have explored its association with the prognosis of type B aortic dissection (TBAD) patients receiving thoracic endovascular aortic repair (TEVAR). Methods A total of 1,425 consecutive patients who underwent TEVAR were included. Data from 935 patients were analyzed in the study. The endpoint was defined as 30-day and 1-year aortic-related adverse events (ARAEs), all-cause mortality, and major adverse cardiovascular and cerebrovascular events (MACCEs). Results There were 935 patients included during a mean follow-up time of 2.8 years. After adjusting for multiple confounding factors, continuous TG/HDL-c [hazard ratio (HR) =1.07; 95% confidence interval (CI): 1.00-1.15; P=0.041] was independently associated with 1-year all-cause mortality. Both a high (Quintile 5: TG/HDL-c ratio ≥4.11) (HR =4.84; 95% CI: 1.55-15.13; P=0.007) and low TG/HDL-c ratio (Quintile 1: TG/HDL-c ratio <1.44) (HR =4.67; 95% CI: 1.46-14.94; P=0.001) were still independent risk factors for 1-year all-cause mortality. Conclusions Elevated baseline TG/HDL-c ratio and TG/HDL-c ≥4.11 were significantly related to a higher risk of 1-year all-cause mortality among TBAD patients undergoing TEVAR. At the same time, the low TG/HDL-c ratio was also independently associated with 1-year all-cause mortality. Special attention should be paid to TBAD patients with a higher or an overly low TG/HDL-c ratio.

Abstract
Background To investigate the clinical efficacy of Castor integrated branched aortic stent graft for the treatment of Stanford type B aortic dissection with insufficient anchoring area. Methods Retrospective analysis of clinical data of 26 patients with Stanford type B aortic dissection with insufficient anchoring region (<15 mm) treated by Castor branched aortic stent graft from September 2018 to June 2022 at Ganzhou People's Hospital, including 23 acute cases and 3 chronic cases. Results Surgical procedures were successfully performed in all 26 patients, and during the perioperative period no complications occurred, such as cerebrovascular accident, stenosis or occlusion of left subclavian artery, progression of reverse avulsion of aortic dissection, and paraplegia. During the operation 2 patients had a small amount of type I endoleak, which disappeared during the postoperative follow-up. The other patients had good postoperative follow-up results. Review of the aortic CTA indicated good stent morphology with patency of the left subclavian artery. Conclusions The Castor integrated branched aortic stent graft expanded the indications for endoluminal treatment for Stanford type B aortic dissection, which can avoid open surgery and has good clinical outcomes.

Abstract
INTRODUCTION Thoracic aortic aneurysms (TAAs) are an increasingly prevalent pathology with significant associated morbidity and mortality. Thoracic endovascular aortic repair (TEVAR) is the primary line of treatment. The purpose of this study was to analyse a single center's experience in the treatment of TAAs and identify possible risk factors for worse outcomes. METHODS A retrospective review of our institutional database was done to identify all patients treated for TAAs in a 10-year period, from 1 January 2012 to 31 December 2022. Data were extracted from patients' medical records. Primary outcome was all-cause mortality and secondary outcomes were procedure related morbidity (vascular access complications, medullary ischaemia, stroke, endoleaks, migration, aneurysm sac enlargement >5 mm) and need for reintervention at 1-, 6- and 12-month follow-up. A descriptive and inferential analysis of the data was performed. Statistical analyses were conducted using the IBM Statistical Package for Social Sciences (SPSS) software. RESULTS We identified 34 patients treated for TAAs in this period. Mean age was 68 years [47-87] and 79.4% of patients were male. Mean aneurysm diameter was 63 mm [35-100], 55.9% fusiform and 44.1% saccular. The majority (91.2%) were located at the descending thoracic aorta and 3 (8.8%) of them extended to the aortic arch. The most common aetiology was degenerative in 22 patients (64.7%), followed by aortic dissection in 8 patients (23.5%). Elective surgery was performed in 19 (61.3%) patients and 12 (38.7%) had urgent repair. TEVAR was the treatment of choice in 24 (77.4%) patients, and the remaining 7 (22.6%) were treated with hybrid surgery. Mean length of hospital stay was 10 days [2-80] (6 days for elective repair versus 16 days for urgent repair, p = .016). Follow-up period ranged from 1 month to 10 years. At 1 year follow-up, all-cause mortality was 15%, morbidity was 30% (with 6 (22%) patients having a type Ia endoleak) and need for reintervention was 22%. Aneurysm diameter was a significant risk factor for procedure related morbidity (median diameter of 73.5 mm versus 56.0 mm in patients with no morbidity; p = .027). The presence of type Ia endoleak was significantly associated with higher reintervention rates (p = .001), but not with higher mortality rates (p = .515). Age, female sex, aetiology and urgent repair weren't associated with any significant differences in the outcomes. CONCLUSIONS TEVAR proved to be effective in the treatment of TAAs, with good outcomes at short and mid-term follow-up. TAAs should be diagnosed earlier and be promptly treated when meeting criteria to prevent worse outcomes.

Abstract
Aortic dissection (AD) is a serious disease with a higher mortality. The thoracic endovascular aortic repair (TEVAR) is a first line regimen for aortic dissection. Hepatic portal venous gas (HPVG) is a rare disease, and its definite mechanism is unknown. This is a rare association between the aortic and HPVG. In the present report, we present a case of thoracic aortic dissection, which was the type of Standford B by the computer tomography (CT) angiography, which implicated acute abdominal pain and abdominal distention after TEVAR and immediate abdominal CT shown hepatic portal venous gas (HPVG). The patient, who was treated with conservative treatment of gastrointestinal decompressing, fluid resuscitation, electrolyte replacement, anti-infection, anti-inflammation and anticoagulation, was recovered and discharged without abnormalities. This patient has been followed up for 5 years and has not experienced any physical discomfort related to HPVG. This is the first report that the aortic dissection patient implication with HPVG after thoracic endovascular aortic repair.

Abstract
BACKGROUND This study aimed to compare the clinical characteristics, treatment approaches, and outcomes of the Stanford Type B traumatic aortic dissection (TAD) with non-traumatic aortic dissection (NTAD), and assess better management for TAD. METHODS We retrospectively analyzed patients who underwent thoracic endovascular aortic repair for Stanford type B aortic dissection at The First Hospital of China Medical University between 2014 and 2022. The patients were divided into TAD and NTAD groups based on whether they had a history of acute trauma. This study ultimately included 65 patients with TAD and 288 with NTAD. We assessed and compared the baseline characteristics, laboratory indicators, imaging features, surgical procedures, and follow-up results between the groups. RESULTS The TAD group was younger compared to the NTAD group (50.00 [IQR40.00-59.00] vs. 55.00 [IQR 47.00-61.00] years, p = 0.020). A lower percentage of the TAD group had a history of hypertension (20% vs. 71.18%, p < 0.001). The length of aortic dissection was shorter in the TAD group compared to the NTAD group (30.00 [IQR 22.00-40.00] vs. 344.00 [IQR 237.25-400.00] mm, p < 0.001). All patients with TAD underwent TEVAR following the same strategy as NTAD. The mean preoperative duration was 7.00 (IQR 2.00-14.00) days in the TAD group and 11.00 (IQR 8.00-15.00) days in the NTAD group (p < 0.001). TAD showed fewer complications after TEVAR in mid-to-long-term follow-up. CONCLUSIONS TAD is distinct from NTAD. TAD typically presents with more localized lesions than NTAD, and the patients experience a shorter preoperative duration and a better mid-to-long-term outcome.

Abstract
Background Special instruments are needed for the revascularization of aortic branches in in situ fenestration during thoracic endovascular aortic repair (TEVAR). This prospective study compared the effectiveness and safety of three currently used fenestraters: laser, needle, and Quick Fenestrater (QF). Methods In all, 101 patients who underwent TEVAR for aortic disease (dissection, n = 62; aneurysm, n = 16, or ulcer, n = 23) were enrolled. All patients were randomly assigned to three groups: 34 were assigned to laser fenestration, 36 to needle fenestration, and 31 to QF fenestration. The epidemiological data, treatment, imaging findings, and follow-up outcomes were analyzed using data from the medical records. Results The technical success rates of the laser, needle, and QF fenestration groups were 94.1%, 94.4%, and 100% (p > 0.05). After correction of mixed factors such as age and gender, it was showed the average operative time (Laser group: 130.01 ± 9.36 min/ Needle group: 149.80 ± 10.18 min vs. QF group: 101.10 ± 6.75 min, p < 0.001), fluoroscopy time (Laser group: 30.16 ± 9.81 min/ Needle group: 40.20 ± 9.91 min vs. QF group: 19.91 ± 5.42 min, p < 0.001), fenestration time (Laser group 5.50 ± 3.10 min / Needle group 3.50 ± 1.50 min vs. QF group 0.67 ± 0.06 min, p < 0.001), and guide wire passage time after fenestration (Laser group 5.10 ± 1.70 min / Needle group 4.28 ± 1.60 min vs. QF group 0.07 ± 0.01 min, p < 0.001) were all shorter with QF fenestration than with the other two tools. The overall perioperative complication rates of the laser, needle, and QF fenestration groups were 5.9%, 5.6%, and 0% (p > 0.05): One case of sheath thermal injury and one case of vertebral artery ischemia occurred in the laser fenestration group; one case each of access site hematoma and brachial artery thrombosis were reported in the needle fenestration group. 89 (88.1%, 89/101) patients were followed for a median of 12.6 ± 1.6 months. The overall postoperative complication rates of the laser, needle, and QF fenestration groups were 3.3%, 6.5%, and 0% (p > 0.05): In the laser fenestration group, there was one death due to postoperative ST-segment elevation myocardial infarction; in the needle fenestration group, one patient developed occlusion of the bridge stent; no complications occurred in the QF group. Conclusion All three fenestration methods were effective in reconstructing supra-arch artery during TEVAR. QF fenestration required less contrast agent, with a shorter surgery duration and fewer complications than laser and needle fenestration.

Abstract
Background Spinal cord ischemia (SCI) is one of the most devastating complications of thoracic endovascular aortic repair (TEVAR). Prophylactic cerebrospinal fluid drainage (CSFD) has been shown to decrease the risk of SCI in open thoracic aortic procedures; however, its utility in TEVAR remains uncertain. This systematic review and meta-analysis aim to determine the role of prophylactic CSFD in preventing SCI in TEVAR. Methods A literature search of five databases was performed and all studies published before September 2022 that reported SCI rates in TEVAR patients undergoing prophylactic CSFD were included. A random effects meta-analysis of means or proportions was performed for single-arm data. Odds ratios (ORs) with 95% confidence intervals (CIs) were reported for comparisons between groups. Results A total of 4,793 patients undergoing TEVAR from 40 studies were included. The mean age was 68.8 years and 70.9% of patients were male. The overall SCI rate was 3.5%, with a 1.3% rate of immediate SCI and a 1.9% rate of delayed SCI. There were no significant differences in SCI rates between prophylactic CSFD patients and non-drained patients. Routine CSFD did not have a significant impact on SCI rates compared to non-drained patients. There was an increased rate of transient SCI with selective CSFD compared to non-drained patients (OR 2.08; 95% CI: 1.06-4.08; P=0.03). The most common drain-related complication was spinal headache (4.3%). The major complication rate was 1.6%, of which epidural or spinal hematoma (0.9%) was the most common, followed by intracranial or subdural hemorrhage (0.8%) and paraparesis or paraplegia (0.8%). Conclusions This study found no significant difference in SCI rates between prophylactic CSFD patients and their non-drained counterparts. CSFD is associated with a small but non-negligible risk of serious complications. Multi-center randomized controlled trials (RCTs) are warranted to help stratify the risk of both SCI and CSFD-related complications in patients undergoing endovascular aortic procedures.

Abstract
A well-placed and functioning lumbar spinal drain, for spinal cord protection, is an important aspect of the perioperative care of patients undergoing thoracic endovascular aortic repair (TEVAR) procedures. Spinal cord injury (SCI) is a devastating complication of TEVAR procedures and is most often associated with Crawford type 2 repairs. Current evidence-based guidelines for the surgical management of patients with thoracic aortic disease include the role of lumbar spine catheter placement and drainage of cerebrospinal fluid (CSF) intraoperatively as part of a strategy to prevent spinal cord ischemia. More often than not, the procedure of lumbar spinal drain placement, using a standard blind technique, and subsequent drain management is the responsibility of the anesthesiologist. However, institutional protocols are inconsistent, and, failure to successfully place the lumbar spinal drain pre-operatively in the operating room, in clinical situations such as patients with poor anatomical landmarks or prior back surgery, presents a clinical dilemma and impacts spinal cord protection during TEVAR. Although a relatively safe procedure, potential complications of lumbar spine catheter placement range from a self-limiting headache to hemorrhage and permanent neurological injury. Spinal drain placement with image-guided fluoroscopy by interventional radiology should be considered in the preoperative assessment and planning and is an alternative to conventional, blind lumbar drain insertion.

Abstract
OBJECTIVES To evaluate incidence and outcomes of ischaemic organ complications after thoracic endovascular aortic repair (TEVAR). METHODS This is a multicentre, retrospective, observational cohort study. We analyzed data from patients treated with TEVAR between June 22nd 2001 and December 10th 2022. Primary outcomes were postoperative overall organ ischaemic complications and early (≤ 30 days) survival. Secondary outcomes were long-term survival, and freedom from aorta-related mortality (ARM). RESULTS A total of 255 patients were included in this study. We performed 233 (91.4%) isolated TEVARs, 14 (5.5%) fenestrated or branched TEVARs, and 8 (3.1%) TEVARs in combination with normal infrarenal stent graft. Overall, 31 organ ischaemic complications were detected in 29 (11.4%) cases, out of which 8 (3.1%) complications were cerebrovascular, 8 (3.1%) spinal cord, 6 (2.3%) visceral, 4 (1.6%) renal, 2 (0.8%) peripheral, and 3 (1.2%) myocardial. Binary logistic regression analysis identified grade III-IV aortic arch atheroma (OR: 6.6, P = 0.001; 95% CI: 2.9-14-9) and shaggy aorta (OR: 12.1, P = 0.003; 95% CI: 2.3-64.1) to be associated with the development of organ ischaemic complications. In patients with organ ischaemia, we observed higher early (≤ 30 days) mortality (20.7% vs 6.2%; OR: 3.6, P = 0.016), prolonged hospitalization (P = 0.001), and inferior estimated survival (Log-rank, P = 0.001). CONCLUSIONS Aortic arch atherosclerotic overload as well as the presence of shaggy aorta are predictors of organ ischaemic complications following TEVAR. They are neither uncommon nor negligible, and are associated with perioperative mortality, prolonged hospitalization, and a negative impact on long-term survival.

Abstract
PURPOSE We aim to quantify multiaxial cardiac pulsatility-induced deformation of the thoracic aorta after ascending thoracic endovascular aortic repair (TEVAR) as a part of the GORE ARISE Early Feasibility Study. MATERIALS AND METHODS Fifteen patients (7 females and 8 males, age 73±9 years) with ascending TEVAR underwent computed tomography angiography with retrospective cardiac gating. Geometric modeling of the thoracic aorta was performed; geometric features including axial length, effective diameter, and centerline, inner surface, and outer surface curvatures were quantified for systole and diastole; and pulsatile deformations were calculated for the ascending aorta, arch, and descending aorta. RESULTS From diastole to systole, the ascending endograft exhibited straightening of the centerline (0.224±0.039 to 0.217±0.039 cm-1, p<0.05) and outer surface (0.181±0.028 to 0.177±0.029 cm-1, p<0.05) curvatures. No significant changes were observed for inner surface curvature, diameter, or axial length in the ascending endograft. The aortic arch did not exhibit any significant deformation in axial length, diameter, or curvature. The descending aorta exhibited small but significant expansion of effective diameter from 2.59±0.46 to 2.63±0.44 cm (p<0.05). CONCLUSION Compared with the native ascending aorta (from prior literature), ascending TEVAR damps axial and bending pulsatile deformations of the ascending aorta similar to how descending TEVAR damps descending aortic deformations, while diametric deformations are damped to a greater extent. Downstream diametric and bending pulsatility of the native descending aorta was muted compared with that in patients without ascending TEVAR (from prior literature). Deformation data from this study can be used to evaluate the mechanical durability of ascending aortic devices and inform physicians about the downstream effects of ascending TEVAR to help predict remodeling and guide future interventional strategies. CLINICAL IMPACT This study quantified local deformations of both stented ascending and native descending aortas to reveal the biomechanical impact of ascending TEVAR on the entire thoracic aorta, and reported that the ascending TEVAR muted cardiac-induced deformation of the stented ascending aorta and native descending aorta. Understanding of in vivo deformations of the stented ascending aorta, aortic arch and descending aorta can inform physicians about the downstream effects of ascending TEVAR. Notable reduction of compliance may lead to cardiac remodeling and long-term systemic complications. This is the first report which included dedicated deformation data regarding ascending aortic endograft from clinical trial.

Abstract
Background The introduction of hybrid total arch replacement with the frozen elephant trunk (FET) technique has improved the field of aortic surgery by allowing single-stage treatment of complex aortic pathologies. Although FET has been associated with favorable aortic remodeling, it is also associated with the potential development of distal stent graft-induced new entries (dSINEs). The aim of our review is to collect data about the incidence and the supposed conditions for the occurrence of dSINE after total hybrid arch replacement with FET technique. Methods The literature review was performed using PubMed databases from inception to January 2022. A descriptive approach to detect and display supposed risk factors and predictors for dSINE occurrence has been adopted. Results Eight studies summarized the state-of-the-art of dSINE in a total number of 544 FET procedures performed to treat acute and chronic aortic dissections. The scoping review showed dSINEs occurrence in 69 patients (12.7%). The mean time between surgery and the diagnosis ranged from 12.6 to 30.6 months. Most patients that developed dSINE received endovascular treatment, whereas a couple of them needed open surgery. According to our experience, from January 2007 to December 2021, in 225 FET procedures a total of 54 cases of dSINE, both with Thoraflex and E-vita grafts have been detected. The mean time between the surgical procedure and the diagnosis was 27.2±33.6 months. Conclusions dSINEs are frequent complications after FET. Although not emergent, they require proper treatment. Due to dSINE's asymptomatic nature and potential harm, a rigorous follow-up including angio-computed tomography (CT) should be planned.

Abstract
Background Aortic arch pathology often requires staged segmental repairs. Total aortic arch replacement with frozen elephant trunk (FET) offers surgical options for these pathologies. The Jotec E-vita Open NEO™ branched prosthesis was introduced in 2020; we sought to share our initial experience focusing on the prosthesis selection strategies, surgical techniques, anastomosis-bleeding and graft-oozing control methods, and early clinical outcomes from two Asian centers. Methods We performed a retrospective cohort study in patients with aortic arch pathologies who underwent total arch replacement using the FET procedure with Jotec E-vita Open NEO™ branched prosthesis from two Asian centers between October 2020 and August 2021. The primary outcome was overall 30-day mortality, and the secondary outcomes were operative complications. Results Twenty-five consecutive patients underwent total arch replacement with FET with the novel hybrid prosthesis. Overall 30-day mortality from both centers was 0%. Overall mean operative, cardiopulmonary bypass, hypothermic circulatory arrest, and selective antegrade cerebral perfusion times were 353.4±80.5, 183.2±39.6, 57.2±14.7, and 138.2±28.6 minutes, respectively. No patient developed stroke. Permanent spinal cord injury (SCI) was recorded in one patient (4%) and one (4%) had transient lower limb weakness that resolved after spinal drainage. There was no requirement of re-sternotomy for hemostasis. Conclusions We reported a multicenter Asian case series with the novel FET hybrid prosthesis demonstrating the feasibility and safety of promising initial clinical outcomes. The technique of circumferential reinforcement of vascular anastomosis for hemostasis may be one of the methods for lowering the rates of re-sternotomy for hemostasis, and proper surgical or transfusion strategies would overcome the excessive oozing of the prosthesis. Long-term follow-up is required for further evaluation of aortic pathology progression and device-related outcomes.

Abstract
BACKGROUND The management of aortic arch pathologies represents a great challenge and is associated with high rates of mortality and morbidity. The invasive and radical open surgical repair (OSR) is the standard of care for this group of patients. A superior endovascular approach via thoracic endovascular aortic repair (TEVAR) has been introduced to treat arch pathologies with specifically designed endografts. This approach was shown to benefit patients who are deemed "high risk" for undergoing OSR as it is a greatly less invasiveness option and thus, yields lower rates of morbidity and mortality. AIMS This commentary aims to discuss the recent study by Tan and colleagues, which reports original data on the neurological outcomes after endovascular repair of the aortic arch using the RELAY™ Branched device. METHODS We carried out a literature search on multiple electronic databases, including PubMed, Ovid, Google Scholar, Scopus, and EMBASE, to collate research evidence on the neurological outcomes of endovascular aortic arch repair with TEVAR. RESULTS Tan and colleagues showed through their original clinical data that the RELAY™ Branched device has a high rate of technical success and favorable neurological outcomes. There were no reported neurological deficits in patients who received the triple-branched RELAY™ Branched device. CONCLUSION The RELAY™ branched endograft is well-established for candidates for aortic arch endovascular repair with favorable neurological outcomes. Multiple considerations can help control the incidence of stroke following endovascular repair. These include optimization of the supra-aortic vessels' revascularization, weighting the embolic risk in patients with atheromatous disease, and careful preoperative assessment to select the best candidates for arch endovascular repair.

Abstract
BACKGROUND At present, the optimal management strategy for chronic type B aortic dissection (CTBAD) remains unknown, as equipoise remains regarding medical management versus endovascular treatment versus open surgery. However, the results over recent years of thoracic endovascular aortic repair (TEVAR) in CTBAD appear promising. The aim of this systematic review was to provide a comprehensive analysis of the available data reporting outcomes and survival rates for TEVAR in CTBAD. METHODS Electronic searches of six databases were performed from inception to April 2021. All studies reporting outcomes, specifically 30-day mortality rates, for endovascular repair of CTBAD were identified. Relevant data were extracted, and a random-effects meta-analysis of proportions or means was performed to aggregate the data. Survival data were pooled using data derived from original Kaplan-Meier curves, which allows reconstruction of individual patient data. RESULTS Forty-eight studies with 2,641 patients were identified. Early (<30 days) all-cause and aortic-related mortality rates were low at 1.6% and 0.5%, respectively. Incidence of retrograde type A dissection in the post-operative period was only 1.4%. There were also low rates of cerebrovascular accidents and spinal cord injury (1.1% and 0.9%, respectively). Late follow-up all-cause mortality was 8.0%, however, late aortic-related mortality was only 2.4%. Reintervention rates were 10.1% for endovascular and 6.7% for surgical reintervention. Pooled rates of overall survival at 1-, 3-, 5- and 10-year were 91.5%, 84.7%, 77.7% and 56.3%, respectively. CONCLUSIONS The significant heterogeneity in the available evidence and absence of consensus reporting standards are important considerations and concern when interpreting the data. Evaluation of the evidence suggests that TEVAR for CTBAD is a safe procedure with low rates of complications. However, the optimal treatment strategy for CTBAD remains debatable and requires further research. Evidence from high-quality registries and clinical trials are required to address these challenges.

Abstract
Background Thoracic endovascular repair (TEVAR) is considered the first-line therapy in the repair of acute complicated type B aortic dissection (AC-BAD). Given the difficulty of designing randomized trials in this surgical cohort, long-term outcome data is limited. This systematic review and meta-analysis provide a complete aggregation of reported long-term survival and freedom from reintervention of AC-BAD patients based on the existing literature. Methods Three databases were searched from date of database inception to January 2021. The relevant references were identified and baseline cohort characteristics, survival and freedom from reintervention were extracted. The primary endpoints were survival and freedom from reintervention, whilst secondary endpoints were post-operative outcomes such as cord ischemia and endoleak. Kaplan-Meier curves were digitized and aggregated as per established procedure. Results A total of 2,812 references were identified in the literature search for review, with 46 selected for inclusion. A total of 2,565 patients were identified, of which 1,920 (75%) were male. The mean age of the cohort was 59.8±5.8. Actuarial survival at 2, 4, 6 and 10 years was 87.5%, 83.2%, 78.5% and 69.7%, respectively. Freedom from all secondary reintervention at 2, 4, 6, 8 and 10 years was 74.7%, 69.1%, 65.7%, 63.9% and 60.9%, respectively. When accounting for study quality, actuarial survival at 2, 4, 6 and 8 years was 85.4%, 79.1%, 69.8% and 63.1%, respectively. Freedom from all secondary reintervention at 2, 4, 6 and 8 years was 73.2%, 67.6%, 63.7% (maintained), respectively. Conclusions TEVAR is associated with promising long-term survival extended to 10 years, though rates of freedom from reintervention remain an ongoing point for improvement. Randomized controlled trials comparing endovascular with open repair in the setting of acute, complicated type B aortic dissection are needed.

Abstract
Objective: The interactions between aortic morphology and hemodynamics play a key role in determining type B aortic dissection (TBAD) progression and remodeling. The study aimed to provide qualitative and quantitative hemodynamic assessment in four different TBAD morphologies based on 4D flow MRI analysis. Materials and Methods: Four patients with different TBAD morphologies underwent CT and 4D flow MRI scans. Qualitative blood flow evaluation was performed by visualizing velocity streamlines and flow directionality near the tears. Quantitative analysis included flow rate, velocity and reverse flow index (RFI) measurements. Statistical analysis was performed to evaluate hemodynamic differences between the true lumen (TL) and false lumen (FL) of patients. Results: Qualitative analysis revealed blood flow splitting near the primary entry tears (PETs), often causing the formation of vortices in the FL. All patients exhibited clear hemodynamic differences between TL and FL, with the TL generally showing higher velocities and flow rates, and lower RFIs. Average velocity magnitude measurements were significantly different for Patient 1 (t = 5.61, p = 0.001), Patient 2 (t = 3.09, p = 0.02) and Patient 4 (t = 2.81, p = 0.03). At follow-up, Patient three suffered from left renal ischemia because of FL collapse. This patient presented a complex morphology with two FLs and marked flow differences between TL and FLs. In Patient 4, left renal artery malperfusion was observed at the 32-months follow-up, due to FL thrombosis growing after PET repair. Conclusion: The study demonstrates the clinical feasibility of using 4D flow MRI in the context of TBAD. Detailed patient-specific hemodynamics assessment before treatment may provide useful insights to better understand this pathology in the future.

Abstract
Despite advances in detection and treatment, acute traumatic aortic injury (ATAI) is associated with high rates of morbidity and mortality. Both physical and hemodynamic forces have been postulated as mechanisms of aortic injury during a traumatic event. For patients who survive the initial injury, rapid detection is critical for diagnosis and procedural planning, which requires a thorough knowledge of both its clinical presentation and the available diagnostic imaging modalities. Radiography, computed tomography (CT), and magnetic resonance imaging (MRI) can each have a role in the diagnosis of ATAI. After stabilization of the patient, the management of ATAI is guided by the severity of injury. Appropriately selected patients with low grade injuries may be managed non-operatively. When treatment is required, there are both open surgical and endovascular options. In current practice, endovascular approaches with stent-graft placement are preferred due to their high clinical success and low rates of complications. Complications from endograft placement can include: endoleak, endograft collapse, infection, endograft failure, and endograft migration. Open surgical repair is now reserved for patients with unfavorable anatomy for endovascular therapies. This review provides a comprehensive overview of ATAI including its epidemiology and demographics, mechanisms of injury, clinical and radiographic diagnosis, treatment options, and post-therapeutic follow-up.

Abstract
PURPOSE This study aimed to investigate the effect of distal aortic segmental enlargement (DASE) after thoracic endovascular aortic repair for complicated type B aortic dissection (cTBAD). MATERIALS AND METHODS From March 2003 to October 2018, 814 patients with acute cTBAD from 5 medical centers were retrospectively identified. DASE is indicated as the enlargement of distal aortic segmental volume ≥1.6 fold of the preoperative volume compared with the most recent postoperative computed tomography angiography (CTA) scan. Of these patients, 635 (78%) were identified as non-DASE, and 179 (22%) were identified as DASE. Competing risk analysis was performed to compare late death and distal aortic reintervention between the groups. The morphological variables and false lumen thrombosis at 7 aortic levels were measured based on the preoperative CTA and the most recent CTA. Univariate and multivariate Cox regression analyses were used to assess the independent predictors of DASE. RESULTS The mean follow-up time of the entire cohort was 5.6 years (interquartile range: 2.4-8.3 years). There were total of 208 late deaths, including 94 (14.8%) deaths in non-DASE group versus 114 (63.7%) deaths in the DASE group. Distal aortic reintervention was observed in 89 patients, with 43(6.7%) in the non-DASE group versus 46 (25.7%) in the DASE group. The cumulative incidence of late death and distal aortic reintervention were significantly higher in the DASE than in the non-DASE group (p<0.001). In morphological analysis, significant incomplete false lumen thrombosis was observed in all distal aortic segments above the aortic level of celiac artery (p<0.01). According to multivariate analysis, the Marfan syndrome, stent coverage to the level of diaphragm and the level of celiac artery were independent predictors of the DASE (p<0.001). Patients with extended stent coverage to the level of celiac artery have shown a lower incidence of DASE (p<0.010). CONCLUSION Compared with the non-DASE group, patients with DASE demonstrated a higher rate of late death and distal aortic reintervention. For the cTBAD population, extended stent-graft coverage to the aortic section between diaphragm and celiac artery might serve as a "cost-efficient" cutoff point aiming to reduce the risk of DASE.

Abstract
Acute aortic dissection is a rare but catastrophic condition. When the dissection extends through the adventitia, blood can extravasate into the extrapleural or intrapleural spaces, causing an extrapleural hematoma or hemothorax. The early recognition of extrapleural hematoma and distinguishing it from hemothorax is critical because the management of those two entities is different. The authors present a case of a late diagnosis of a large extrapleural hematoma in a patient with Stanford type B acute aortic dissection that required thoracotomy for hematoma evacuation. The patient underwent successful thoracic endovascular aortic repair (TEVAR). Postoperatively, the patient had worsening pulmonary function, with a large fluid collection on imaging that was not drained by the thoracostomy tubes. Surgical exploration revealed a large extrapleural hematoma. Timely recognition of the extrapleural hematoma was key in the patient's clinical management. Without clear radiographic diagnostic features of extrapleural hematoma, unsuccessful drainage of hematoma after insertion of a chest tube may suggest an extrapleural hematoma or a clotted hemothorax. If patients continue to have circulatory or respiratory compromises, prompt surgical exploration should be considered. It is important for clinicians to be aware of extrapleural hematoma in complicated acute aortic dissection, especially when chest tube drainage of an apparent hemothorax is unsuccessful.

Abstract
Objective: The treatment for arch aneurysms by endovascular repair is often difficult. This study evaluated the long-term outcomes of thoracic endovascular aortic repair for aortic arch aneurysms treated with the Najuta stent-graft system. Materials and Methods: From January 2009 to December 2019, 37 patients underwent treatment for aortic aneurysms with the Najuta stent graft system at two institutes, including our hospital. We retrospectively analyzed the short- and long-term clinical outcomes. Results: Of all 37 cases, the technical success rate was 97.3% (36 of 37). The mean proximal neck length was 20.1±5.3 mm. The postoperative results revealed 10 patients with type Ia endoleaks (27.8%), 6 with stroke (16.7%), and one with paraplegia (2.8%). In the chronic phase, the overall survival rates and the rates of freedom from aorta-related events at 7 years were 71.3% and 50.7%, respectively. Between two groups divided based on the proximal neck diameter of 20 mm, the <20-mm group had significantly higher rates of aorta-related events in terms of freedom from aortic events (P=0.046). Conclusion: The fenestrated stent graft can be a less invasive option for the treatment of high-risk patients with aortic aneurysms.

Abstract
Background This study analyzes the outcomes of a one-stage hybrid procedure combining thoracic endovascular aortic repair (TEVAR) with extra-anatomic bypass in patients with distal aortic arch disease. Methods This retrospective study collected 103 hybrid procedures combining TEVAR with extra-anatomic bypass (mean age, 62.2±9.3 years; 90 males) performed from January 2009 to January 2019 at Beijing Anzhen Hospital. We analyzed 30-day and mid-term outcomes including survival rate and the incidence of stroke, spinal cord injury (SCI), and endoleak. Results Five deaths (4.6%) occurred within 30 days, including type I endoleak in Zone 1 (n=1), hemorrhagic shock (n=1), stroke (n=2), and stent migration (n=1). Two patients developed SCI. The median follow-up time was 39.5 (interquartile range, 13.6-69.0) months. In all, 14 late deaths occurred; these were due to stroke (n=2), severe pneumonia (n=1), aortic rupture caused by type I endoleak (n=3), and sudden death (n=8). Six late endoleaks occurred including three type I and one type II in Zone 1 and two type I in Zone 2. In a competing risks analysis, the incidences of reintervention at 7 years, late death, and survival without reintervention were 8%, 22%, and 70%, respectively. In a Cox risk model, stroke (HR, 21.602; 95% CI: 2.798–166.796; P=0.003) was the only risk factor for 30-day mortality. Stroke (HR, 19.484; 95% CI: 5.245–72.380; P<0.001), SCI (HR, 15.548; 95% CI: 2.754–87.786; P=0.002), and endoleak (HR, 4.626; 95% CI: 1.068–20.040; P=0.041) were independent risk factors for long-term mortality. Conclusions The one-stage hybrid procedure provides acceptable mid-term results with good mid-term patency of extra-anatomic bypass. Strict selection of patients suitable for hybrid repair can effectively improve the survival rate and reduce the incidence of complications. At the same time, close follow-up patients should receive close long-term follow-up after hybrid procedure.

Abstract
OBJECTIVE To evaluate outcomes of patients with acute complicated or chronic Type B or non-A non-B aortic dissection who underwent the frozen elephant trunk (FET) technique. METHODS Between April 2013 and July 2019, 41 patients presenting with acute complicated (n = 29) or chronic (n = 12) descending thoracic aortic dissection were treated by the FET technique, which was the treatment of choice when supra-aortic vessel transposition would not suffice to create a satisfactory proximal landing zone for endovascular aortic repair, when a concomitant ascending or arch aneurysm was present, or in patients with connective tissue diseases. RESULTS One patient (2%) died intra-operatively secondary to an aortic rupture in dwnstream aortic segments. No post-operative deaths occurred. Four patients (10%) suffered a non-disabling posto-operative stroke and were discharged with no clinical symptoms (modified Rankin Scale [mRS] 0, n = 1), no significant disability (mRS 1, n = 2), or with slight disability (mRS 2, n = 1). No spinal cord ischaemia was observed. The primary entry tear was either surgically resected or excluded from circulation in all patients. During follow up, one patient (2%) died after two years (not aorta related) and 16 patients (39%) underwent an aortic re-intervention after 7.7 [interquartile range 0.7, 15.8] months (endovascular aortic repair: n = 14; open thoraco-abdominal aortic replacement: n = 1, hybrid approach: n = 1). CONCLUSION The FET technique is an effective treatment option for acute complicated and chronic Type B or non-A non-B aortic dissection in patients in whom primary endovascular aortic repair is non-feasible. While the post-operative outcome is acceptable with a relatively low incidence of non-disabling strokes, this study also underlines the considerable need for aortic re-interventions. Continuous follow up of all patients undergoing the FET procedure is essential.

Abstract
Background Total arch replacement (TAR) with frozen elephant trunk (FET) was challenging in patients with prior thoracic endovascular aortic repair (TEVAR), for complicated arch pathology and anatomy. In this study, we aimed to present our experiences in TAR with FET after prior TEVAR, and compare the clinical outcomes between the aortic balloon occlusion technique and the conventional technique. Methods Between January 2016 and December 2019, 30 patients with prior TEVAR received TAR with FET in our hospital. The aortic balloon occlusion technique was applied in 9 patients, and the conventional technique in 21 patients. The median time interval from TEVAR to reoperation was 9 months (0–168 months). The indications for TAR with FET included retrograde type A aortic dissection, endoleak, arch false aneurysm and new ascending dissection. Results The patients with the balloon occlusion technique had shorter cardiopulmonary bypass time than patients with the conventional technique (151.2±31.3 vs. 183.4±46.8 min, P=0.036). The aortic-clamp time was also shorter in the balloon occlusion group, but without significant difference. The hypothermia circulatory arrest duration was significantly decreased in the balloon occlusion group (5.7±4.1 vs. 21.6±7.5 min, P<0.001). The incidence of major adverse events was 13.3%, and the mortality was 6.7%. No significant differences in the incidence of major adverse events, and the mortality were noted between the two groups. Follow-up was available in 28 survivors. The mean follow-up time was 25.4±13.0 months. No late death, aortic reoperation and complications occurred during follow-up. Conclusions TAR with FET was a safe and effective procedure in patients with prior TEVAR, with satisfactory early and late outcomes. The aortic balloon occlusion technique could be applied in these patients, and may provide some protective effects.

Abstract
A case of a 46-year-old car driver struck with great force by a tram through the driver's door is presented. The main trauma consisted in chest injury with multi-rib fracture along with rupture and dissection of the thoracic aorta. Immediate medical rescue actions consisted only in procedures necessary to support vital functions; the patient survived owing to being promptly transported to the Emergency Department to undergo thoracotomy and laparotomy with massive blood transfusion. Polytrauma angio-CT scan revealed a posttraumatic thoracic aorta lesion which in turn was treated by deployment of an endovascular thoracic stent graft. This way, the immediate risk of death was averted, and the remaining traumatic lesions and conditions could be treated. Patient was discharged to a Rehabilitation Center on the 49th day of treatment. The authors stress that trauma resulting from accidents with this particular mechanism, i.e. lateral car crash on the driver's side with the driver's door being staved in by the tram, should be managed by immediate transport of the patient to the Emergency Center. In such cases early drainage of the pleural cavity can deteriorate patient's status by increasing the bleeding from the ruptured aorta.

Abstract
Thoracic endovascular aortic repair (TEVAR) is used to treat retrograde type A acute aortic dissection (RTAAD). In case 1, a 52-year-old man, who was conservatively managed, reported worsening back pain. Emergency TEVAR was performed 7 days after onset. After deploying two GORE Conformable TAG (CTAG) in the descending aorta, his symptoms disappeared. In case 2, a 52-year-old man with progressive worsening resistant hypertension, renal dysfunction, and respiratory failure despite maximal medical therapy underwent TEVAR 8 days after onset. A CTAG was deployed from the left subclavian artery under rapid pacing, and two Zenith Dissection stents were placed, which resolved complications. In both cases, after 6 months, computed tomography (CT) scan showed complete resorption of the false lumen in the ascending aorta. TEVAR for RTAAD with complete thrombosis of false lumen in the ascending aorta can be an alternative to surgery when the primary tear is located in descending aorta.

Abstract
Penetrating aortic ulcer (PAU) of the arch has a focal extent which often represents an adequate anatomic target for thoracic endovascular aortic repair (TEVAR). However, the anatomic constraints represented by the supra-aortic vessels pose either clinical or technical challenges that increase when the PAU develops proximally in the arch. Currently, different types of endografts are commercially available and have been used to treat aortic arch lesions. These include branched/fenestrated endografts for a total endovascular approach, and standard devices that can be used in combination with open/hybrid surgical operations, with the aim to exploit the minimally invasive nature of TEVAR by extending the proximal landing zone when necessary. We describe several current techniques adopted in such settings.

Abstract
Background Aortic intramural hematoma constitutes one of the three classifications of acute aortic syndrome (AAS). Type B intramural hematoma (IMH-B) is localized to the descending thoracic aorta and can be managed through medical, endovascular or surgical means. Data comparing contemporary management with thoracic endovascular aortic repair (TEVAR) versus traditional medical management (MM) is sparse and only moderate strength recommendations for TEVAR are provided in guidelines. This meta-analysis aimed to pool available data from comparative studies between TEVAR and MM and examine differences in outcomes. Methods Literature search of electronic medical databases was conducted to identify studies comparing TEVAR and MM for management of IMH-B. Data extraction from studies fulfilling the inclusion criteria was performed by two authors and meta-analysis using a random-effects model applied to pool baseline data and examine risk ratios (RR) for management outcomes. Results Of the initial 2,349 studies, nine studies were identified for analysis. There were 161 TEVAR patients and 166 who were medically managed. The mean age of the cohort was 62.2 years [95% confidence interval (CI): 55.8-68.7 years]. Patients with complicating features of IMH-B at presentation were more likely to appear in the TEVAR group, with more penetrating atheromatous ulcer (PAU) [risk difference (RD), 0.565, 95% CI: 0.240-0.889, P=0.001], ulcer-like projection (ULP) (RD 0.240, 95% CI: 0.965-0.384, P=0.001), and greater IMH size (mean difference, MD 5.47 mm, 95% CI: 0.320-10.6, P=0.037). There was no statistical difference between TEVAR and MM for the primary endpoints of aortic-related death (RR 0.535, 95% CI: 0.191-1.5, P=0.234) or IMH-B regression (RR 1.25, 95% CI: 0.859-1.81, P=0.246). Of the secondary endpoints, TEVAR had both significantly less dissection during follow-up (RR 0.295, 95% CI: 0.0881-0.989, P=0.048) and less rupture during follow-up (RR 0.206, 95% CI: 0.0462-0.921, P=0.039). Conclusions A small number of series comparing TEVAR and MM for management of IMH-B are available and random-effects meta-analysis did not reveal any statistically significant difference between treatments for aortic related death or IMH-B regression at a mean follow-up of 37 months. TEVAR was found to be associated with lower risk of dissection and lower risk of rupture during follow-up. Baseline data meta-analysis showed patients with complicating features of PAU, ULP, and larger IMH size were more likely to be managed with TEVAR.

Abstract
Background To report the long-term outcomes of balloon-expandable bare stent (BEBS) as chimney stent (CS) in thoracic endovascular aortic repair (TEVAR) for supra-aortic branches reconstruction. Methods A total of 33 patients with thoracic aortic diseases underwent TEVAR using BEBSs as CSs for supra-aortic branches reconstruction in our center from 2010 to 2015. The demographics and procedural details were prospectively collected and retrospectively reviewed. All patients were followed up at 1, 3, 6 months and every 1 year thereafter. Postoperative complications and long-term outcomes were recorded. Results The technical success rate was 100%. A total of 36 BEBSs were utilized as CSs to reconstruct the supra-aortic branches during TEVAR. The rate of immediate endoleak was 42.4% (14/33), including 12 (36.4%) type Ia endoleaks and 2 (6.1%) type II endoleaks. Two of type Ia endoleaks were managed by balloon dilation and disappeared, while the rest were left with close follow-up. Two type II endoleaks were embolized by coils and excluded by a plug, respectively. One patient (3.0%) died 2 days after the procedure due to the acute rupture of aortic dissection. The mean follow-up time was 61.8 (ranged from 12 to 102) months. The unmanaged 10 type Ia endoleaks were closely observed during the follow-up, of which 7 disappeared at 1 year and 1 disappeared at 2 years. The rest 2 type Ia endoleaks existed without further dilation of the aorta. One patient (3.0%) was re-intervened for the increased false lumen due to the distal residual tears. The long-term mortality was 9.1% (3/33). All CSs kept patent till the end of follow-up. No other complications were found. Conclusions The balloon-expandable stent (BES) is a feasible choice as CS for supra-aortic branches reconstruction with long-term patency during TEVAR. However, BEBS may be related to a higher rate of early endoleak.

Abstract
We report a rare case of delayed paraplegia triggered by gastrointestinal (GI) bleeding 8 months after thoracic endovascular aortic repair (TEVAR). A 78-year-old male underwent TEVAR of a descending thoracic aortic aneurysm without a postoperative neurological deficit and was discharged. Magnetic resonance image showed spinal cord infarction from Th8 to L1, and enhanced computed tomography showed a patent Adamkiewicz artery. The ostium of the intercostal artery connected with the Adamkiewicz artery was occluded. Patients with a history of TEVAR might be more vulnerable to spinal cord ischemia around the Adamkiewicz artery, which can be triggered by common hemorrhagic diseases, such as GI bleeding, even remote from the procedure.

Abstract
Background To report the experience of a single centre regarding the application of the triple-chimney technique using C-TAG with Viabahn or Excluder iliac extension devices for the endovascular management of aortic arch dilation diseases. Methods From July 2016 to August 2017, 7 patients (5 men; mean age 56.1±10.8 years) with aortic arch dilation diseases were treated with the triple-chimney technique. All patients were followed up at 1, 3, and 6 months and every 6 months thereafter. Results Six innominate arteries were deployed with Excluder iliac extensions and one with a Viabahn cover-stent. All the left common carotid arteries and left subclavian arteries were placed with Viabahn. Reverse chimney technique was applied in four patients. Three (42.0%) type I endoleaks were found on the final angiogram. Two were apparently reduced, and one disappeared after balloon dilation. The mean follow-up time was 15.7 months (9-20 months). All the type I endoleak was found disappeared within 3 months. One patient died of myocardial infarction at 6 months after discharge. No other complications such as stent-graft migration, occlusion, type II endoleak or neurological stroke occurred. Conclusions The use of C-TAG coupled with Viabahn or Excluder iliac extension is feasible and effective for the treatment of aortic arch dilatation diseases. However, more patients and longer follow-up time are required to verify its long-term safety and efficacy.

Abstract
Aorto-esophageal fistulas (AEFs) are rare after thoracic endovascular aortic repair (TEVAR), being associated with the presence of mediastinal hematoma and the need for emergency TEVAR. Left untreated, AEFs are always lethal. "Redo"-stent-grafting can serve as a "bridging" procedure in hemodynamically unstable patients, but is not a durable therapy. Radical surgery is shown to be the most durable and effective treatment. This includes esophagectomy, stent-graft removal and aortic replacement followed by esophageal reconstruction, e.g., gastric pull-up operation. Aortic reconstruction can be performed by the use of self-made bovine pericardial tubes. A bilateral anterior ("clam-shell") thoracotomy can be chosen for surgical exposure in revision cases after previous sternotomy, in which the ascending aorta, aortic arch and proximal descending aorta require reconstruction.

Abstract
Background Precise stent graft sizing in Thoracic endovascular aortic repair (TEVAR) is crucial to receive optimal long-term results. Computed tomography (CT), as the current standard in assessing aortic diameters (ADs), is often performed at initial diagnosis. Since several acute aortic diseases are associated with blood loss and/or volume re-distribution, assessed AD might be influenced by impaired hemodynamic conditions. Intravascular ultrasound (IVUS) offers real-time assessment, especially after hemodynamic restoration, and might help for stent graft choice. Methods We investigated the correlation between CT and later IVUS measurements in elective (n=83) and emergency patients (n=32) at the level distal to the left subclavian artery (LSA), a frequent proximal landing zone in TEVAR. Patients were grouped depending on their shock index (heart rate/systolic blood pressure): emergency patients with diagnosis of acute aortic syndrome, urgently required treatment after admission and had a shock index >1, otherwise were grouped as elective. Basic hemodynamics were assessed for both groups at admission and at definite IVUS-procedure. Results At time of admission the emergency group showed lower blood pressure (99±19.8 vs. 141±24 mmHg; P=0.001) and higher heart rate (98±13 vs. 70±12 bpm; P=0.001) compared to elective patients. By hemodynamic stabilization comparable blood pressure and heart rate were achieved in both groups at time of IVUS. In the emergency group, we found a significantly increase in AD after hemodynamic stabilization, whereas the diameters did not change in the elective group (IVUSmeanvs. CTmean: 5.1±1.0 vs. 0.4±2.2 mm; P=0.001 and IVUSminvs. CTmean: 3.9±1.3 vs. -0.3±2.2 mm; P=0.011). Conclusions IVUS for stent graft sizing is a valuable approach during TEVAR, especially in the light of emergency treatment by offering real-time assistance. Impaired hemodynamic conditions might lead to relevant changes in AD and may strongly influence stent graft choice. In these cases, careful stent graft selection might contribute to avoidance of stent graft related complication.

Abstract
Background Distal aortic complications from acute DeBakey I dissection repair are an important source of late morbidity and mortality. We present an early experience of using a novel single-branched thoracic aortic endograft in conjunction with open techniques to treat acute DeBakey I aortic dissection. Methods The patients in this series include five hyperacute dissections managed with a combined zone 2 partial arch replacement and placement of a zone 2 single subclavian branch endograft. Results There were no perioperative mortalities, strokes, or spinal cord ischemia in any patients at either stage of the procedure. At follow-up imaging, no patients had anterograde flow into the false lumen. All patients experienced false lumen thrombosis in the stented portion of the aorta. Conclusions This combination of open repair techniques and the use of a novel branched endograft resulted in excellent early outcomes in this pioneer series. Further investigation of these techniques in a prospective fashion is warranted.

Abstract
BACKGROUND Thoracic endovascular aortic repair (TEVAR) in the current era has gained widespread acceptance as the modality of choice for the treatment of complicated aortic dissection (AD). However, reports on clinical results of TEVAR treatment of AD patients are mainly comparisons and analyses of results between patients in the acute and chronic phases, few reports have described the postoperative aortic remodelling of patients with subacute AD after TEVAR. The aim of this study was to investigate aortic remodelling after TEVAR in acute and subacute Stanford type B AD patients. METHODS The clinical data of 38 Stanford type B AD patients who received TEVAR treatment in our hospital between July 2012 and December 2017 were retrospectively analysed. The maximum diameters of the aorta, the mean diameters of the true lumens (TLs) and the false lumens (FLs) of the aorta in the dissection range before and after TEVAR treatment were measured. All diameters between different groups or in the same group before and after therapy were compared using nonparametric tests. Count data were examined using the χ2 test. RESULTS The 38 patients were 31.0-82.0 years old with a mean age of 57.0±11.0 years, including 31 men and 7 women, with 22 patients in the acute phase and 16 patients in the subacute phase. Among the 38 patients included in this study, 7 (18.4%) patients had endoleaks after treatment. No perioperative deaths occurred. Analyses of computed tomography angiography measurement results showed that the baseline maximum diameters of the aorta, TLs and FLs before TEVAR between the acute and subacute groups were not significantly different (P=0.193, P=0.301 and P=0.067, respectively). After TEVAR treatment, the maximum diameters of the aorta and the diameters of the FLs were different between the two groups (P=0.005 and P=0.012), but the diameters of the TLs were not (P=0.069). The diameters of the TLs increased, and those of FLs decreased significantly in the acute and subacute groups after TEVAR (P<0.001, P<0.001, P<0.001 and P=0.007, respectively); the maximum diameters of the aorta decreased significantly in the acute group (P<0.001), but they did not change obviously in the subacute group (P=0.121). CONCLUSIONS TEVAR offers satisfactory results for the treatment of type B AD. Acute AD may be associated with better aortic remodelling compared to subacute AD after TEVAR.

Abstract
Background Stanford type B aortic dissection is one of the aortic catastrophes with a high mortality and morbidity that needs immediate or delayed treatment, either surgically or endovascularly. This comprehensive review article addresses the current status of open, endovascular and hybrid treatment options for type B aortic dissections with the focus on new therapeutic perspectives. Methods Evaluation of currently available evidence based on randomized and registry data and personal experience. Results All type B dissections require prompt medical treatment to prevent aortic rupture. Acute complicated dissections are nowadays treated by endografting to reroute blood flow into the true lumen and promote false lumen thrombosis and future aortic remodeling. In acute uncomplicated situations the position of endografting is less clear and should be further delineated; however, on the long run also in these situations endografting might be protective for future aortic catastrophes in certain patient categories. In the chronic dissection with aneurysm formation of the descending thoracic and/or thoracoabdominal aorta, especially in connective tissue disorders, open surgery offers nowadays the best immediate results with long durability. Thoracic endografting plays only a minor role in these circumstances but branched and fenestrated endografting are very promising techniques. Hybrid techniques can offer the solution for high risk patients that are not suitable for open surgery. Conclusions Emergent thoracic endografting is the golden standard for all complicated type B dissections while uncomplicated patients with high-risk features might benefit from endovascular repair. Open surgery is limited for chronic post dissection aneurysms. Aortic surveillance is of paramount importance in all situations.

Abstract
Considerable progress has been made in the management of diseases of the thoracic and abdominal aorta over the past decades, ranging from advances in open repair to the advent of minimally invasive endovascular techniques. Along with this comes an equivalent rise in imaging necessity for these patients, both in preoperative planning and postoperative surveillance. With the growing complexity and diversity of vascular procedures and techniques, it is essential to have a solid understanding of the imaging features and postoperative complications of these procedures to avoid imaging pitfalls. This review is an attempt to define the normal postoperative appearance and important complications of various open and endovascular surgical techniques of the thoracic and abdominal aorta.

Abstract
"The major goal of surgery for acute type A aortic dissection is to have an alive patient." This motto still remains the most important directive. However, also depending onto the extent of the underlying pathology and consecutively depending onto the extent of primary surgery, there is and will be need for additional classical surgical or interventional treatment sooner or later during follow-up in a substantial number of patients having had surgery for acute type A aortic dissection. This article shall guide the interested reader through the underlying mechanisms as well as treatment options in patients with chronic type B "residual" after type A repair and shall finally suggest preventive strategies to reduce the occurrence of this pathology to a minimum.

Abstract
The patient described herein was a 75-year-old female. Echocardiography showed patent ductus arteriosus (PDA). Heart failure symptoms gradually appeared, and she was referred to our department for treatment. Contrast-enhanced computed tomography (CT) revealed a tubular structure communicating between the aortic arch and pulmonary artery trunk, suggesting adult PDA. Thoracic endovascular aortic repair (TEVAR) was performed to close PDA. Completion angiography confirmed the disappearance of PDA. Post-TEVAR CT revealed no endoleak. The patient was discharged from the hospital on the 11th day after surgery. TEVAR is more useful and less invasive for adult PDA than conventional open surgery.

Abstract
BACKGROUND Traumatic thoracic aortic dissection is uncommon in clinical practice; however, it is associated with high morbidity and mortality. Thoracic aortic dissection is usually caused by sudden deceleration resulting from a traffic accident or fall. Aortic injury after blunt trauma is a critical condition. This study reported the outcomes of endovascular repair of acute traumatic aortic dissection in patients at a district general hospital. METHODS In this study, we retrospectively reviewed the clinical data of eight patients with acute traumatic aortic dissection after a blunt trauma who had undergone thoracic endovascular aortic repair (TEVAR) between January 2012 and December 2015 at a district general hospital in Taiwan. RESULTS The median age of the patients was 49±22 years (range, 20-77 years), and 6 of the 8 (75%) patients were men. Five patients were involved in traffic accidents, and 3 patients had fallen from heights. The injury severity score (ISS) of the patients ranged from 17 to 66. In all patients, the aortic injury was located near the origin of the left subclavian artery (LSA). Four patients had seal ostium of subclavian artery, left. None of the patients developed paraplegia or lower extremity ischemia. Moreover, all patients had concomitant injuries, and no patients died postoperatively. CONCLUSIONS Endovascular repair is a rapid and minimally invasive therapy for patients with traumatic aortic injury and is associated with favorable technical results.

Abstract
PURPOSES When placing stent grafts, deployment accuracy and birdbeaking due to inadequate conformability and device apposition along the inner curvature of the arch have been encountered. The new Conformable GORE® TAG® Thoracic Endoprosthesis (CTAG) is designed to have enhanced compression resistance and improved conformability in difficult anatomy. The present study compared the deployment accuracy and conformability of the CTAG Device with TAG Device. METHOD Deployment accuracy and birdbeaking was compared of CTAG Device and TAG Device implantation for initial treatment of thoracic aortic aneurysm conducted by our department between March 2010 and March 2012. Deployment accuracy was defined as the distance between the actual and intended device implantation locations measured from DSA images. RESULTS Deployment accuracy at the time of implantation (mean ± SD) was significantly better for the CTAG Device compared to the TAG Device (2.2 ± 1.7 mm vs. 4.4 ± 3.0 mm, P <0.05). Also, while birdbeaking was seen in 8 of 20 cases (40%) for the TAG Device, it was only seen in 1 of 12 cases (8%) for the CTAG Device. CONCLUSION The present study found enhanced deployment accuracy and conformability along the aortic arch using the CTAG Device compared to the previous-generation TAG Device.

Abstract
BACKGROUND The treatment of chronic type B aortic dissection (CBAD) remains complicated. Thoracic endovascular aortic repair (TEVAR) has supplanted open surgical repair (OSR) as the preferred surgical treatment for CBAD. Despite TEVAR's superior short-term results, much less is understood about its long-term outcomes. As much of the understanding of OSR originates from historical report, contemporary series, with modern surgical techniques and technologies, may present an alternative to TEVAR. The present systematic review will assess the short- and long-term outcomes of historic and contemporary series of OSR for CBAD. METHODS Electronic searches were performed using six databases from their inception to March 2014. Relevant studies with OSRs for chronic type B dissection were identified. Data were extracted by two independent reviewers and analyzed according to predefined clinical endpoints. Studies were sub-classified into the pre-endovascular (historic series) and endovascular era (contemporary series) depending on whether the majority of cases were performed after 1999. RESULTS Nineteen studies were identified for inclusion for quantitative analysis. Pooled short-term mortality was 11.1% overall, and 7.5% in the nine contemporary studies. Stroke, spinal cord ischemia, renal dysfunction, and reoperation for bleeding were 5.9%, 4.9%, 8.1%, and 8.1%, respectively, for the contemporary series. Absolute late reintervention was identified in 13.3% of patients overall, and in 11.3% of patients in the contemporary series. Aggregated survival at 1-, 3-, 5-, and 10-years of all patients were 82.1%, 74.1%, 66.3%, and 50.8%, respectively. CONCLUSIONS OSR for chronic type B dissection in the contemporary era offers acceptable results. Management approaches should be considered carefully, taking into account both short-term and long-term complications. More research is required to clarify specific indications for OSR and TEVAR in chronic type B dissections.

Abstract
Acute type B aortic dissection comprises approximately one-third of all aortic dissection cases. Although this catastrophic cardiovascular condition was first described in the medical literature over two centuries ago, data on the optimal diagnostic and treatment modalities for type B dissection was slow to evolve throughout the latter half of the twentieth century, even as newer diagnostic techniques and management strategies became commonplace. To further elucidate contemporary practice patterns and outcomes of aortic dissection, the International Registry of Acute Aortic Dissection (IRAD) was established in 1996. Over the past two decades, IRAD publications have steadily increased our knowledge and understanding about aortic dissection. Specifically in recent years, analyses of IRAD data have gone beyond simply characterizing the patient with acute type B aortic dissection and have attempted to identify the means by which the outcome of such a patient could be improved. Thus, we present herein three areas in which IRAD data has recently advanced our understanding of acute type B aortic dissection: temporal classification especially for the subacute time period, risk stratification for identifying complicated cases, and thoracic endovascular aortic repair (TEVAR).

Abstract
OBJECTIVE Available data on outcomes of combined proximal stent-grafting with distal bare stenting for management of aortic dissection are limited. The objective of this study was to provide a systematic review of outcomes of this approach. METHODS Studies involving combined proximal stent-grafting with distal bare stenting for management of aortic dissection were systematically searched and reviewed through MEDLINE databases. RESULTS A TOTAL OF FOUR STUDIES WERE INCLUDED: 108 patients treated for management of acute (n=54) and chronic (n=54) aortic dissection. The technical success rate was 95.3% (range, 84-100%). The 30-day mortality rate was 2.7% (range from 0% to 5%). The morbidity rate occurring within 30 days was 51.8% (range from 0% to 65%) and included stroke (2.7%), paraplegia (2.7%), retrograde dissection (1.8%), renal failure (14.8%), severe cardiopulmonary complications (5.5%) and bowel ischemia (0.9%). The incidence of type I endoleak was 9.2% (10/108). During follow-up, 5 (4.6%) deaths were related to aortic rupture or aortic repair. Mean re-intervention rate was 12.9%. Two cases (1.9%) of delayed retrograde type A dissection and one case of aortobronchial fistula (0.9%) were reported. The most common delayed complication was thoracic stent-graft migration (4.7%). The rate of device failure was 9.2%. Favorable aortic remodeling was observed: studies reporting midterm follow-up of the true lumen demonstrated a high rate of both false lumen regression and true lumen expansion. At 12 months, complete false lumen thrombosis was observed at the thoracic level in 70.4% and at the abdominal level in 13.5% of patients. CONCLUSIONS Combined proximal stent-grafting with distal bare stenting appears to be a feasible approach for the management of Type B aortic dissection. Although this approach clearly improved true lumen perfusion and diameter, it failed to completely suppress false lumen patency. However, it should be acknowledged that contemporary data on this approach is limited to small studies with variable results.

Abstract
Dynamic aortic evaluation in planning thoracic endovascular aortic repair (TEVAR) is important to provide optimal stent graft sizing. Static imaging protocols do not consider normal aortic dynamics and may lead to stent graft to aorta mismatch, causing stent graft related complications, such as type I endoleak and stent graft migration. Dynamic imaging can assist in accurate stent graft selection and sizing preoperatively, and evaluate stent graft performance during follow-up. To create new imaging technologies, integration of knowledge between diverse scientific fields is essential (i.e., engineering, informatics and medicine). Different dynamic imaging modalities, such as electrocardiographic-gated computed tomography angiography (ECG-gated CTA) and four-dimensional phase-contrast MRI (4D PC-MRI), are progressively investigated and implemented into clinical practice as important instruments in preoperative planning for TEVAR. In time, further application of dynamic imaging tools for preoperative screening and follow-up after TEVAR might lead to better outcomes for patients. The advances in dynamic imaging for evaluation of the thoracic aorta using new imaging modalities and their future perspectives are addressed in this manuscript.
