Abstract
PURPOSE To define the learning curve of a widely employed stent-graft for thoracic endovascular repair (TEVAR) by analyzing procedural variables and their impact on long-term outcomes. MATERIALS AND METHODS Standard TEVARs for each major aortic thoracic disease were included excluding procedures using thoracoabdominal, arch fenestrated/branched devices and/or chimneys. The primary outcome was the learning curve analysis using the cumulative sum chart method. The secondary outcomes, presented as early (Q1-Q2) versus latest (Q3-Q4) quartiles of experience, were 30-day major adverse events (MAEs); procedural details (additional maneuvers, operative and fluoroscopy time, and contrast volume); 30-day clinical success; endoleak; aorta-related reintervention; and overall and aorta-related survival. RESULTS Between November 2005 and September 2021, 220 consecutive TEVAR procedures involving the Relay endograft (Terumo Aortic, Sunrise, FL, USA) were performed and included in the present analysis. The mean follow-up was 4.5 ± 3.9 years. The learning curve was reached after 10 patients. Secondary outcomes improved significantly over experience. Thirty-day MAE occurrence was 14.5% versus 11.8% (p=0.550). Additional maneuvers (p=0.009), access-vessel additional maneuvers (p=0.010), operative time (p=0.004), Relay Plus (p=0.001), and implantation of multiple stent-grafts (p=0.034) were independent risk markers for MAEs. Operative time (125.9 ± 66.7 vs 86.7 ± 48.5 minutes, p<0.001), contrast volume (185.4 ± 112.8 vs 140.5 ± 88.2 mL, p=0.003), and fluoroscopy time (12.4 ± 12.7 vs 8.8 ± 7.5 minutes, p=0.017) decreased significantly. Late endoleak occurrence was 19.5% with a nonsignificant reduction (21.8% vs 17.3%, p=0.395). Fluoroscopy time (hazard ratio [HR]=1.0; 95% confidence interval [CI]=1.0-1.1; p=0.008), contrast volume (HR=1.0; 95% CI=1.0-1.1; p=0.018), and type III aortic arch (HR=3.3; 95% CI=1.7-6.4; p<0.001) were independent risk markers for endoleak. Fluoroscopy time (HR=1.0; 95% CI=1.0-1.1; p=0.032) and type III aortic arch (HR=3.6; 95% CI=1.7-7.4; p=0.001) confirmed their significant association in a multivariable analysis. CONCLUSION In a high-volume center with a consistent previous endovascular experience, the Relay graft presented satisfactory long-term results with a short learning curve supporting its reliability. CLINICAL IMPACT The manuscript addresses the understanding of how many TEVAR procedures with a currently implanted device have been required to reach the learning curve for an endovascular skilled center. Our TEVAR experience with the Relay stent-graft (Terumo Aortic) demonstrated that ten implantations were required to achieve the device-related learning curve. The fifteen-year analyzed period showed that intraoperative learning-related variables were associated with long-term clinical outcomes and both improved over time. The Relay stent-graft presented satisfactory long-term results along with a short learning curve in a high-volume endovascular center supporting its ongoing implantation.

Abstract
AIM The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. STRUCTURE Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

Abstract
Background Here we analyzed mid-term data of thoracic endovascular aneurysm repair (TEVAR) surgery with Castor single-branched stent graft placement for the management of Stanford type B aortic dissection (STBAD) involving the left subclavian artery (LSA). Methods Between April 2014 and February 2019, 32 patients with STBAD involving a Castor single-branched stent graft were included. We analyzed their outcomes, including technical success rate (TSR), surgical duration (SD), presence of ischemia, perioperative complications, LSA patency, and survival rate (SR), using computed tomography angiography and clinical evaluation during mid-term follow-up. Results The mean patient age was 54.63 ± 12.37 years (range, 36-83 years). The TSR was 96.88% (n = 31/32). The mean SD was 87.44 ± 10.89 with a mean contrast volume of 125.31 ± 19.30 mL. No neurological complications or deaths occurred during the study period. The patients had a mean hospital stay of 7.84 ± 3.20 days. At a mean follow-up of 68.78 ± 11.26 months, four non-aortic deaths (12.5%) were observed. The LSA patency rate was 100% (n = 28/28). There was only one case of type I endoleak immediately after surgery (3.12%) (type I from LSA). However, none of the patients experienced type II endoleaks, and there were no cases of retrograde type A aortic dissection or stent graft-driven new distal entry. Finally, all patients exhibited good LSA patency. Conclusion TEVAR using a Castor single-branched stent graft may be a highly feasible and efficient procedure for the management of STBAD involving the LSA.

Abstract
PURPOSE OF REVIEW Acute aortic syndromes, including aortic dissection, intramural hematoma, and penetrating aortic ulcer, are a group of highly morbid, related pathologies that are defined by compromised aortic wall integrity. The purpose of this review is to summarize current management strategies for acute aortic syndromes. RECENT FINDINGS All acute aortic syndromes have potential for high morbidity and mortality and must be quickly identified and managed with the appropriate algorithm to prevent suboptimal outcomes. Recent trials suggest that TEVAR is increasingly useful in stabilizing pathology of the descending thoracic aorta but when possible should be applied in a delayed fashion and with limited coverage to minimize neurologic complications. Treatment for acute aortic syndrome is frequently dictated by the anatomic location and extent of the wall compromise as well as patient comorbidities. Therapy is often individualized and often includes some combination of medical, procedural, and surgical intervention.

Abstract
For decades, the mainstay of management for acute, uncomplicated type B aortic dissection (TBAD) has been anti-impulse medical therapy, focusing on close control of blood pressure, and heart rate. However, the natural history of this entity has remained one of aortic degeneration over time and significant morbidity and mortality. More recently, the advent of endovascular therapy has driven a revolution in the management of TBAD. While thoracic endovascular aortic repair (TEVAR) was rapidly adopted for the treatment of complicated type B aortic dissection due to significantly improved morbidity and mortality when compared with tradition open surgical techniques, its role in the management of uncomplicated dissection remained controversial. However, the accumulation of favorable data on aortic remodeling and survival following early TEVAR for uncomplicated dissection is driving a shift in paradigm and practice. This is particularly true of patients exhibiting certain features at the time of presentation that are associated with increased risk of failure of optimal medical therapy. This article reviews the current evidence in the literature addressing TEVAR for acute, uncomplicated TBAD. In addition, it presents the state of the art in FDA-approved thoracic endograft platforms, guidance regarding case planning, and step-by-step procedural description, including the management of common challenges, and complications.

Abstract
Purpose: To evaluate the safety and efficacy of a novel vascular-friendly thoracic stent graft for patients with acute complicated type B aortic dissection (ac-TBAD). Methods: A multicenter retrospective study was undertaken in which we prospectively collected data in consecutive ac-TBAD patients treated by thoracic endovascular aortic repair (TEVAR) with the Ankura Thoracic Stent. Complications, true lumen rate (TLR), and mortality were recorded. Follow-up computed tomography angiography (CTA) was performed at 1, 6, and 12 months postoperatively and yearly thereafter. Results: Altogether, 63 patients with ac-TBAD in four medical centers were included. No deaths or serious complications occurred during the perioperative period. The mean follow-up time was 30.1 ± 18.9 months. All-cause mortality rate was 3.1% (n = 2). TEVAR-related mortality rate was 1.6% (n = 1) because of retrograde type A dissection (RTAD) at 6 months. The other death was caused by acute myocardial infarction (AMI) during the third postoperative month. A distal endoleak detected at 3 months in one patient (1.6%) was treated by reintervention. The use of this novel vascular-friendly thoracic stent graft in ac-TBAD postoperative patients significantly improved their TLR. Conclusion: The novel vascular-friendly thoracic stent graft showed satisfactory results, with favorable stability of the aortic diameter during follow-up.

Abstract
In recent guidelines of international societies, the most frequent indication for treatment after chronic type B aortic dissection (cTBAD) is aneurysmal dilatation. Endovascular repair is recommended in patients with moderate to high surgical risk or with contraindications to open repair. During the last decade, many advances have been made in the field of endovascular techniques and devices. The aim of this article is to address the current status of endoluminal techniques for the management of cTBAD including standard thoracic endovascular repair, new devices, fenestrated and branched abdominal aortic devices and false lumen occlusion techniques.

Abstract
The frequency of endovascular stent grafting procedures to treat various conditions of the thoracic aorta has increased dramatically over the past three decades. Stent grafting has been applied on a limited basis in patients with Marfan syndrome and other connective tissue disorders, despite recommendations from current guidelines and expert consensus statements against its use in this setting. A review of publications reporting outcomes after stent grafting of the descending thoracic aorta in Marfan patients with acute or chronic aortic dissection indicates that these procedures can be accomplished with rates of early mortality, stroke and spinal cord ischemic injury that are comparable to those observed in patients who do not have Marfan syndrome. However, the rates of primary treatment failure (principally endoleak), secondary treatment failure, need for open repair and late death among the Marfan patients are substantially higher than those observed in patients without this condition. In addition, the rates of retrograde aortic dissection and development of stent-graft induced new entry (SINE), are also greater among patients with Marfan syndrome. All of these findings argue strongly against the routine use of endovascular grafts in Marfan patients with type B or residual type A dissection. Few data are available to assess the role of endografting in Marfan patients with aneurysmal disease, but the progressive aortic dilatation noted in these patients argues strongly against its use in this setting as well. At present, the available data indicate that there is no justification for elective stent grafting in Marfan patients with aortic dissection or aneurysm. The only reasonable indications for primary aortic stent grafting are in the setting of acute aortic dissection or rupture, where the intervention is considered life-saving and rarely, considering the relatively young age of these patients, where the risk of open operation is considered to be prohibitive.

Abstract
OBJECTIVE During the past decade, thoracic endovascular aortic repair (TEVAR) has increased as a treatment option for a variety of aortic pathologic processes. Despite this rise in the use of thoracic stent grafts, real-world outcomes from a robust, adjudicated, contemporary data set have yet to be reported. Previous studies have shown periprocedural mortality rates between 1.5% and 9.5% and procedure-related stroke rates of 2.3% to 8.2%. With advances in device engineering and increased experience of physicians, we hypothesized that the rates of these complications would be reduced in a more recent sample set. The purpose of this study was to determine current rates of mortality and stroke after TEVAR, to identify risk factors that contribute to 30-day mortality, and to develop a simple scoring system that allows risk stratification of patients undergoing TEVAR. METHODS We examined the 30-day mortality rate after TEVAR using the 2013 to 2014 American College of Surgeons National Surgical Quality Improvement Program database. Patients undergoing TEVAR for all aortic disease were identified using procedure codes. Bivariate analyses were performed to evaluate the association of preoperative, intraoperative, and postoperative variables with 30-day mortality, followed by multivariable logistic analysis using preoperative variables only, with P < .10 as the criterion for model entry. The predictive logistic model was internally validated by cross-validation. Variables included in the multivariable model were used to develop a risk score. RESULTS There were 826 patients included. The 30-day mortality and stroke rates were 7.63% (n = 63) and 4.5% (n = 37), respectively. In regression analysis, mortality was independently associated with age ≥80 years (odds ratio [OR], 2.32; 95% confidence interval [CI], 1.25-4.31), emergency case (OR, 2.61; 95% CI, 1.39-4.90), American Society of Anesthesiologists classification >3 (OR, 2.89; 95% CI, 1.34-6.24), transfusion >4 units in the 72 hours before surgery (OR, 2.86; 95% CI, 1.30-6.28), preoperative creatinine concentration ≥1.8 mg/dL (OR, 2.07; 95% CI, 1.05-4.08), and preoperative white blood cell count ≥12 × 109/L (OR, 2.65; 95% CI, 1.41-4.96). Incorporating these factors, a 6-point risk score was generated and demonstrated high predictability for overall 30-day mortality. CONCLUSIONS Recent data from a national, retrospective data set demonstrate that high perioperative mortality and stroke rates have persisted during the last decade. The risk score derived from this data set is simple and convenient and serves as a prognostic tool in the preoperative risk stratification of patients being evaluated for TEVAR.

Abstract
Background The aim of this study was to analyze device conformability in TEVAR of acute and chronic (a/c) type B aortic dissections (TBAD) using the Gore Conformable Thoracic Aortic Stent-graft (CTAG). Material/Methods From January 1997 to February 2014, a total of 90 out of 405 patients in our center received TEVAR for TBAD. Since November 2009, 23 patients (16 men; median age: 62 years) were treated with the CTAG. Indications were complicated aTBAD in 15 (65%) and expanding cTBAD in 8 (35%) patients. Primary endpoints were the assessment of device conformability by measuring the distance (D) from the radiopaque gold band marker (GM) at the proximal CTAG end to the inner curvature (IC) of the arch on parasagittal multiplanar reformations of CT angiography, as well as the evaluation of aortic diameter changes following TEVAR. Median follow-up was 13.3 months (range: 2 days to 35 months). Results Primary and secondary success rates were 91.3% (21/23) and 95.6% (22/23), respectively. There was 1 type Ia endoleak, retrograde dissection or primary conversion was not observed. Median GM-IC-D was 0 mm (range: 0 mm to 10 mm). GM-IC-D was associated with zone 2 placement compared to zone 3 (P=0.036). There was no association between GM-IC-D formation and arch type. In aTBAD cases the true lumen significantly increased after TEVAR (P=0.017) and the false lumen underwent shrinkage (P=0.025). In cTBAD patients the false lumen decreased after TEVAR (P=0.036). Conclusions The CTAG shows favorable conformability and wall apposition in challenging arch pathologies such as TBAD.

Abstract
A 21-year-old male suffered blunt trauma from a motor vehicle accident causing thoracic aorta tear. The smallest available stent graft was deployed. Definitive repair was later performed using a 22 × 22 × 116 mm Talent Thoracic Stent Graft. The postoperative course was uneventful. Seventeen months later, he presented with dizziness, chest pain, acute renal failure, malignant hypertension, and troponin elevation. Computed tomography (CT) angiogram and transesophageal echocardiogram did not reveal any dissection, stent stenosis or collapse. Cardiac catheterization showed normal coronary arteries but a 117 mm Hg gradient across the stent graft. Iatrogenic coarctation of the aorta was confirmed with a second measurement during arch angiogram. A Palmaz stent was deployed over the distal end of the previous stent graft with complete resolution of symptoms and gradual normalization of kidney function. This case report demonstrates a need for wider availability and selecting appropriate stent graft in treating traumatic aortic injuries in young patients. It is the first case report of the inability of current imaging modalities in confirming stent collapse. Pressure gradient is a useful tool in confirming stent collapse when clinical scenario does not match CT findings.

Abstract
Endovascular correction of aortic arch pathology remains a challenge, with a variety of techniques proposed over the years to minimize complications and enhance the probability of a successful result. A variety of approaches have been developed in order to deal with the aortic arch pathology and its idiosyncrasies. We review potential interventional techniques for the repair of aortic arch pathologies, beginning with conventional aortic arch surgery, followed by hybrid treatments and those along the endovascular spectrum (parallel and fenestrated endografts, scalloped endografts, and ascending and new branched endografts). We finish with an overview of all the Bolton Medical (Barcelona, Spain and Sunrise, FL, USA) thoracic platforms. Endovascular techniques show acceptable results in selected cases. Both proximal Bolton Relay configurations (with and without a bare stent) offer conformability and accuracy on deployment with very low rates of stroke. Fenestrated and scalloped designs are also useful for selected cases. Ascending and branched Bolton devices are very promising platforms for a serious, full endovascular approach to the aorta.

Abstract
Objective To discuss the currently available approaches to prevent spinal cord injury during thoracic and thoracoabdominal aortic repairs. Methods We carried out a PubMed search up to 2013 using the Medical Subject Headings: “aortic aneurysm/surgery” and “spinal cord ischemia”; “aortic aneurysm, thoracic/surgery” and “spinal cord ischemia”; “aneurysm/surgery” and “spinal cord ischemia/cerebrospinal fluid”; “aortic aneurysm/surgery” and “paraplegia”. All 190 original articles satisfying our inclusion criteria were analyzed for incidence, predictors, and other pertinent variables related to spinal cord injury, and we compared the results in recent publications with those in earlier reports. Results The mean age of the 38,491 patients was 65.3 ± 4.9 years. The overall incidence of paraplegia and/or paraparesis was 7.1% ± 6.1% (range 0%–32%). The incidence of spinal cord injury before 2000, from 2001 to 2007, and 2008–2013 was 9.0% ± 6.7%, 7.0% ± 6.1%, and 5.9% ± 5.2%, respectively ( p = 0.019). Various predictors of spinal cord injury were identified, extent of disease being the most common. Modification of surgical techniques, use of adjuncts, and better understanding of spinal cord perfusion physiology were attributed to the decrease in postoperative spinal cord injury in recent years. Conclusions Spinal cord injury after thoracic and thoracoabdominal aortic repair poses a real challenge to cardiovascular surgeons. However, with evolving surgical strategies, identification of predictors, and use of various adjuncts over the years, the incidence of spinal cord injury after thoracic/thoracoabdominal aortic repair has declined. Embracing a multimodality approach offers a good insight into combating this grave complication.

Abstract
Right-sided aortic arch (RAA) is a rare congenital disorder. We describe herein two cases of thoracic aortic aneurysm with a right aortic arch and right-sided descending aorta treated with thoracic endovascular aortic repair (TEVAR). In one case, a 70-year-old man with Edwards type 1 RAA underwent TEVAR using a Relay stent-graft (Bolton Medical, Barcelona, Spain). In another case, a 72-year-old woman with Edwards type 3 RAA underwent TEVAR using a Kawasumi Najuta stent-graft (Kawasumi Laboratories, Inc., Tokyo, Japan) with the "buffalo horn chimney technique", our original method for left subclavian artery flow preservation. The postoperative courses were uneventful. Postoperative computed tomography showed complete exclusion of the aneurysm without endoleakage. Compared to conventional open surgical repair, TEVAR is challenging in patients with a RAA and right-sided descending aorta. However, our results showed that TEVAR might be feasible and a treatment option even in a patient with a RAA and right-sided descending aorta.

Abstract
BACKGROUND The management of acute type B dissection represents a clinical challenge. We undertook a systematic review of the available literature regarding medical, surgical and endovascular treatments of acute type B aortic dissection and combined the eligible studies into a meta-analysis. METHODS An extensive electronic health database search was performed on all articles published from January 2006 up to November 2013 describing the management of acute type B aortic dissection. Studies including less than 15 patients were excluded. RESULTS ACUTE COMPLICATED TYPE B DISSECTION: overall, 2,531 patients were treated with endovascular repair (TEVAR) and the pooled rate for 30-day/in-hospital mortality was 7.3%. The pooled estimates for cerebrovascular events, spinal cord ischemia (SCI) and total neurologic events were 3.9%, 3.1% and 7.3%, respectively. A total of 1,276 patients underwent open surgical repair and the pooled rate for 30-day/in-hospital mortality was 19.0%. The pooled rate for cerebrovascular events was 6.8%, for SCI 3.3% and for total neurologic complications 9.8%. Acute uncomplicated type B dissection: outcome of 2,347 patients who underwent conservative medical management were analyzed. The pooled 30-day/in-hospital mortality rate was 2.4%. The pooled rate for cerebrovascular events was 1%, for SCI 0.8% and for overall neurologic complications 2%. CONCLUSIONS Endovascular repair provides a superior 30-day/in-hospital survival for acute complicated type B aortic dissection compared to surgical aortic reconstruction. However, open repair still has a significant role as endovascular repair is not applicable in all patients and there remains concerns regarding the durability of this technique. TEVAR seems to have a more favorable outcome regarding aortic remodeling and the aortic-specific survival rate when compared with medical therapy alone. Randomized controlled trials focusing on the prognostic factors of early and late complications in uncomplicated type B dissections are needed.

Abstract
Despite advances in surgical techniques and postoperative management, the in-hospital mortality rate for patients undergoing conventional open surgical repair for type B dissections is still significant. In light of this, the less invasive surgical procedure for acute type B aortic dissections, defined as thoracic endovascular aortic repair (TEVAR), was developed. Despite some controversy, the use of TEVAR for the management of type B aortic dissections has become commonplace. Generally, the main entry tear in type B aortic dissection is located in the vicinity of the orifice of the left subclavian artery (LSA). The proximal landing zone in the aortic arch must be secured as long as the aim of TEVAR for type B dissection is primary entry closure. This requires hybrid surgery that includes the use of open surgical procedures, such as debranching for revascularization of cervical branches. Despite the presence of challenging anatomic conditions in the aortic arch, hybrid repair has evolved as an increasingly viable alternative, and promising early and long-term results have been reported. As the next step, fenestrated and branched TEVAR techniques have recently been reported with satisfactory early results. In the coming years, there will be intense competition to develop the devices themselves, improve delivery systems, and supplement devices with auxiliary functions. Thus there is high expectations for the next generation and how they will improve and advance treatment methods of TEVAR for type B aortic dissections.

Abstract
Open repair is still the gold standard in acute type A dissection. Endovascular repair is advocated for complicated acute type B dissections. Recent evidence also supports the role of endovascular repair in a larger proportion of uncomplicated acute type B dissections. The role of endovascular repair in chronic post-dissection aneurysms, however, is still unclear. Most commonly, post-dissection aneurysms involve the thoracoabdominal aorta, making the use of fenestrated/branched stent-grafts to achieve complete aneurysm exclusion mandatory. These fenestrated/branched stent-grafts have been used with success in atherosclerotic thoracoabdominal aortic aneurysms (TAAAs). In chronic post-dissection aneurysms, however, additional technical challenges arise. The usually narrow true lumen makes the use of branches more tedious and overall planning difficult. A second technical challenge relates to the fact that visceral branches can also originate from the false lumen. In such cases, perforation of the stiff chronic dissection flap is required to obtain access to the vessel. During the period January 2010 to November 2013, 17 patients (13 males, mean age 65±7.8 years) with chronic thoracoabdominal aneurismal degeneration following acute dissection were treated in our department with the use of fenestrated/branched stent-grafts. Technical success was achieved in all cases (100%). Perioperative mortality was two (11.8%) patients. One patient died due to multiple organ failure and one due to cardiac failure. No case of paraplegia was observed. During a 12-month median follow-up (range, 4-28 months) no aneurysm-related deaths were observed. Reintervention was required in three cases to repair a type Ib endoleak from a side branch. Endovascular treatment with fenestrated/branched stent-grafts is feasible for chronic post-dissection aneurysms. Standard thoracic stent-grafting is an option in a minority of patients, when the aneurysm is limited to the thoracic segment. Fenestrated and branched devices can successfully be used for aneurysms extending to the thoracoabdominal aorta.

Abstract
PURPOSE To assess the safety, efficacy and performance of the RELAY NBS PLUS stent-graft in patients with aortic arch pathology. METHODS From July 2010 to December 2011, the RELAY NBS PLUS was used to treat 13 patients (eight males; mean age 59.8 years, range 29-78 years) suffering from aortic arch pathology. The distribution of the proximal landing zone was Zone 0 in one case, Zone 1 in three cases and Zone 2 in nine cases. Bypass of the cervical branches was performed in 11 patients. RESULTS The surgery-related mortality within 30 days and postoperative morbidity were 0%. Postoperative computed tomography at discharge confirmed 100% clinical success without any endoleaks. The mean radius of the inner curve in the aortic arch was 16.2 mm (range 5.8-25.7 mm). We detected two bird-beak configurations with a severely angulated aortic arch with a radius of the inner curve <15 mm. At the mid-term follow-up (mean 22.1 months; range 13.8-28.2 months), all patients were alive without aorta- or device-related complications. CONCLUSIONS RELAY NBS PLUS stent-grafts can be safely and effectively implanted with controlled deployment to satisfactorily repair aortic arch pathology, even in the cases considered to present with an unfavorable anatomy for the first generation commercially available stent-graft devices. These encouraging outcomes will need to be confirmed in a larger series with a longer follow-up.

Abstract
BACKGROUND Aortic dissection is a lift-threatening medical emergency associated with high rates of morbidity and mortality. The incidence rate of aortic dissection is estimated at 5 to 30 per 1 million people per year. The prompt and correct diagnosis of aortic dissection is critical. This study was to compare the ascending aortic image quality and the whole aortic radiation dose of high-pitch dual-source CT angiography and conventional dual-source CT angiography. METHODS A total of 110 consecutive patients with suspected aortic dissection and other aortic disorders were randomly divided into two groups. Group A underwent traditional scan mode and Group B underwent high-pitch dual-source CT scan mode. The image quality and radiation dose of two groups were compared. RESULTS Close interobserver agreement was found for image quality scores (κ = 0.87). The image quality of ascending aorta was significantly better in the high-pitch group than in the conventional group (2.78 ± 0.46 vs 1.57 ± 0.43, P < 0.001). There was no significant difference of the CT attenuation values, the aortic image noise and SNR between two groups. The mean radiation dose of high-pitch group was also significantly lower than that of conventional group (2.7 ± 0.6 mSv vs. 3.9 ± 0.9 mSv, P < 0.001). CONCLUSIONS High-pitch dual-source CT angiography of the whole aorta can provide motion-artifact-free imaging of the ascending aorta at a low radiation dose compared to conventional protocol.

Abstract
INTRODUCTION We analyzed the short-term efficacy of endovascular treatment for aortic diseases by summarizing all available published data on endovascular stent-graft treatment for abdominal aortic aneurysm (AAA), thoracic aortic aneurysm (TAA), type A aortic dissection (type A AD) and type B aortic dissection (type B AD) in China. METHODS We performed a systematic analysis of 935 published series on retrograde endovascular treatment for aortic diseases in China from January 1996 to November 2010. Based on the inclusion criteria, 159 studies, involving a total of 5531 patients, were included. RESULTS There were no significant differences in procedural success among the studies (P>0.05). The rates of overall neurologic complications and stroke were significantly different in all two-group comparisons (P<0.01). The type A AD patients had the highest rates of neurologic complications (both 6.67±0.00%), and the AAA patients had the lowest rates (0.31±0.04% and 0.11±0.02%). Significant differences were noted in the rates of cardiac, renal, pulmonary and visceral complications, which were all higher in the type A AD patients than in the other three groups (P<0.01). The endoleak rate was highest in the TAA patients (19.27±5.74%) and was similar in the type A AD patients (P>0.05). A significant difference was noted between the 30-day mortality rate of the type A AD patients and the AAA or type B AD patients (P<0.05). CONCLUSION Endovascular stent-graft is a feasible and safe treatment for aortic diseases, with high procedural success and low incidences of post-procedural complications and short-term mortality. Endovascular treatment for AAA and type B AD is more efficient than for type A AD and TAA.

Abstract
This present study aims to investigate the changes in the inflammatory markers after elective endovascular treatment of Type B aortic dissection with aneurysm, as related to different anatomical features of the dissection flap in the paravisceral perfusion. Consecutive patients with type B aortic dissections with elective endovascular stent graft repair were recruited and categorized into different groups. Serial plasma levels of cytokines (Interleukin-1β, -6, -8, -10, TNF-α), chemokines (MCP-1), and serum creatinine were monitored at pre-, peri- and post-operative stages. The length of stent graft employed in each surgery was retrieved and correlated with the change of all studied biochemical parameters. A control group of aortic dissected patients with conventional medication management was recruited for comparing the baseline biochemical parameters. In total, 22 endovascular treated and 16 aortic dissected patients with surveillance were recruited. The endovascular treated patients had comparable baseline levels as the non-surgical patients. There was no immediate or thirty day-mortality, and none of the surgical patients developed post-operative mesenteric ischaemia or clinically significant renal impairment. All surgical patients had detectable pro-inflammatory mediators, but none of the them showed any statistical significant surge in the peri-operative period except IL-1β and IL-6. Similar results were obtained when categorized into different groups. IL-1β and IL-6 showed maximal levels within hours of the endovascular procedure (range, 3.93 to 27.3 higher than baseline; p = 0.001), but returned to baseline 1 day post-operatively. The change of IL-1β and IL-6 at the stent graft deployment was statistically greater in longer stent graft (p>0.05). No significant changes were observed in the serum creatinine levels. In conclusion, elective endovascular repair of type B aortic dissection associated with insignificant changes in inflammatory mediators and creatinine. All levels fell toward basal levels post-operatively suggesting that thoracic endovascular aortic repair is rather less aggressive with insignificant inflammatory modulation.

Abstract
OBJECTIVE To quantify longitudinal changes in intra-arterial septum (IS) motion with two-dimensional (2D) phase-contrast magnetic resonance imaging (2D pcMRI) in type B aortic dissections (AD) to improve the understanding of AD and its midterm development. METHODS From a database of 42 patients who underwent a dynamic magnetic resonance imaging (MRI) examination at the Acute Aortic Treatment Center of The Methodist DeBakey Heart & Vascular Center, 2D pcMRI image data was available from 10 patients with type B AD for both short-term (mean, 6.6 days; range, 1-10 days; n = 7) and midterm follow-up (mean, 155 days; range, 60-324; n = 5). IS motion was quantified as motion of IS boundary points averaged over the cardiac cycle. Relative change in IS motion was expressed as percent change compared with initial presentation. Maximum IS extension (true lumen [TL] expansion) and contraction (TL compression), IS fraction in phase with aortic flow and correlation of IS motion with aortic flow (IS compliance) were quantified. RESULTS IS motion at initial presentation was 0.68 ± 0.2 mm and was reduced at short-term (0.48 ± 0.3 mm; P = .07) and midterm (0.5 ± 0.2 mm; P = .1) follow-up. Trend in relative change of IS motion was variable during short-term follow-up: reduced in three subjects (-75% ± 6%) and elevated in four subjects (48% ± 23%). During midterm follow-up, relative change in IS motion was reduced in four subjects (28% ± 19%) and slightly elevated in one (6.2%). IS contraction decreased with follow-up while IS extension slightly increased. Fraction of IS moving in phase with aortic flow increased but IS compliance decreased, suggesting increasing IS stiffness. CONCLUSIONS Reduction of IS motion in AD is seen with short-term and midterm follow-up. Intersubject variability of this trend is high at short-term follow-up but low at midterm follow-up. Detailed analysis of IS motion parameters indicate reduction of IS contraction and IS compliance with time. This has potential implications for endovascular management of type B aortic dissections, as expansion of aortic stent grafts can be limited by a stiff IS.
