Abstract
OBJECTIVE We conducted a systemic review and meta-analysis to compare the association between prophylactic cerebrospinal fluid drainage (CSFD) vs non-CSFD in preventing spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) for aneurysm and dissection. METHODS The MEDLINE, Embase, and Cochrane databases were systematically searched to identify all relevant studies reported before April 1, 2020. A systematic review and meta-analysis were performed. We assessed the association between CSFD strategies, including routine CSFD vs selective CSFD or no CSFD, and the SCI rates after TEVAR for patients with aortic dissection (AD), solitary thoracic aortic aneurysm (TAA), or thoracoabdominal aortic aneurysm (TAAA). Subgroup analyses were conducted to assess the association between different aortic pathologies, including AD and thoracic aneurysms, and SCI rates after TEVAR with and without prophylactic CSFD. The data are presented as the pooled event rates (ERs) and 95% confidence intervals (CIs). RESULTS A total of 34 studies of 3561 patients (2671 with TAA or TAAA and 890 with type B AD) were included in the present analysis. The data are presented as the pooled ERs and 95% CIs. The overall SCI rate for patients who had undergone TEVAR with prophylactic CSFD for AD (ER, 1.80%; 95% CI, 0.88%-2.72%) was significantly lower than that for the aortic aneurysm group (ER, 5.73%; 95% CI, 4.20%-7.27%; P < .0001). The SCI rate after TEVAR with prophylactic CSFD was not significantly different from that without CSFD for AD (P = .51). No association was found between the rates of SCI after TEVAR with routine prophylactic CSFD vs selective prophylactic CSFD for aortic aneurysms (P = .76) and AD (P = .70). The SCI rate after TEVAR without CSFD for aortic aneurysms, including isolated TAA and TAAA (ER, 3.49%; 95% CI, 0.23%-6.76%) was not significantly different from that for AD (ER, 3.20%; 95% CI, 0.00%-7.20%; P = .91). For the patients with TAAAs, the rate of SCI after TEVAR with routine prophylactic CSFD was significantly lower than that with selective prophylactic CSFD (P = .04). CONCLUSIONS Our systematic review and meta-analysis has shown that SCI occurs more often after TEVAR for aortic aneurysms than for AD. Routine prophylactic CSFD, compared with selective CSFD, was associated with a lower rate of postoperative SCI after TEVAR for TAAAs. No significant association was found between the SCI rate and routine prophylactic CSFD for patients undergoing TEVAR for isolated TAA or AD.

Abstract
BACKGROUND Endovascular techniques have become an essential tool for treatment of thoracic aortic pathology. The objective of this study was to analyze indications and results of thoracic endovascular aortic repair (TEVAR) in vascular surgery units, through a retrospective and multicentric national registry called Regis-TEVAR. METHODS From 2012 to 2016, a total of 287 patients from 11 vascular surgery units, treated urgently and electively, were recruited consecutively. The primary variables analyzed are mortality, survival, and reintervention rate. The following indications for TEVAR were also analyzed: aortic dissections, thoracic aneurysms, traumatisms, and intramural hematomas or penetrating ulcers, as well as results and postoperative complications in accordance with each indication. RESULTS Of the 287 TEVAR performed (239 men, mean age 64.1 ± 14.1 years), 155 were because of aortic aneurysm (54%), 90 because of type B aortic dissection (31.4%), 36 because of traumatic aortic rupture (12.5%), and 6 because of penetrating ulcers or intramural hematomas (2.1%). Overall mortality at 30 days was 11.5% (18.5% in urgent and 5.3% in elective), being higher in dissections (13.3%). The median actuarial survival was 73% at 4 years. The stroke rate was 3.1%, and the rate of spinal cord ischemia was 4.9%. Aortic reoperations were necessary in 23 patients (8.1%). CONCLUSIONS This registry provides complete and reliable information on real clinical practice of TEVAR in Spain, with results similar to international series of open surgery. In accordance with these data, TEVAR can be performed with acceptable morbidity and mortality and with low rates of postoperative complications.

Abstract
PURPOSE To report a "real-world" multicenter experience in the use of thoracic endovascular aortic repair (TEVAR) for diseases of the descending thoracic aorta. METHODS A prospective, multicenter, German TEVAR Registry was established in October 2008 and enrolled 191 patients (134 men; mean age 64.5±13.2 years) from 7 hospitals up to March 2011. Stent-graft implantation was performed for Stanford type B aortic dissection (104, 55.3%), true thoracic aortic aneurysm (91, 48.7%), intramural hematoma (20, 10.7%), penetrating aortic ulcer (16, 8.6%), and traumatic aortic rupture (6, 3.2%). RESULTS Per patient, a mean of 1.2±0.7 stent-grafts were implanted. Technical success was 92.1% (164/178); 15 (8.5%) endoleaks (types I-III) were reported. Intervention duration was a mean 107±122 minutes. During the hospital stay, stroke occurred in 3.9% of patients (7/180) and paraplegia in 1.7% (3/180). Reintervention was performed in 3.3% (6/180). The mortality was 5.5% (10/181) in-hospital and 5.6% at 30 days. The mean follow-up was 24.5±27.7 months. The Kaplan-Meier estimates of 1-year reintervention and death rates were 7.2% and 11.4%, respectively. CONCLUSION In this real-world TEVAR registry for acute or chronic descending aortic diseases, technical success was high and the short-term complication rate was acceptable. However, the high reintervention rate observed in the present study mandates thorough clinical and imaging follow-up after an initially successful procedure.

Abstract
BACKGROUND The use of thoracic endovascular aneurysm repair (TEVAR) is increasing. Similar to open repair, TEVAR carries a risk of spinal cord ischemia (SCI). We undertook a systematic review to determine whether preoperative cerebrospinal fluid (CSF) drainage reduces SCI. METHODS PubMed, the Cochrane Library, and conference abstracts were searched using the keywords thoracic endovascular aortic repair, cerebrospinal fluid, spinal cord ischaemia, TEVAR, and aneurysm. Studies reporting SCI rates and CSF drain rates for TEVAR patients were eligible for inclusion. SCI rates across studies were pooled using random-effects modeling. Study quality was evaluated using the Downs and Black score. RESULTS Study quality was generally poor to moderate (median Downs and Black score, 9). The systematic review identified 46 eligible studies comprising 4936 patients; overall, SCI affected 3.89% (95% confidence interval, 2.95.05%-4.95%). Series reporting routine prophylactic drain placement or no prophylactic drain placement reported pooled SCI rates of 3.2% and 3.47%, respectively. The pooled SCI rate from 24 series stating that prophylactic drainage was used selectively was 5.6%. CONCLUSIONS Spinal chord injury is uncommon after TEVAR. The role of prophylactic CSF drainage is difficult to establish from the available literature. High-quality studies are required to determine the role of prophylactic CSF drainage in TEVAR.

Abstract
A thoracic aortic aneurysm (TAA) is a potentially life-threatening condition with structural weakness of the aortic wall, which can progress to arterial dilatation and rupture. Today, both an increasing awareness of vascular disease and the access to tomographic imaging facilitate the diagnosis of TAA even in an asymptomatic stage. The risk of rupture for untreated aneurysms beyond a diameter of 5.6 cm ranges from 46% to 74% and the two-year mortality rate is greater than 70%, with most deaths resulting from rupture. Treatment options include surgical and non-surgical repair to prevent aneurysm enlargement and rupture. While most cases of ascending aortic involvement are subject to surgical repair (partially with valve-preserving techniques), aneurysm of the distal arch and descending thoracic aorta are amenable to emerging endovascular techniques as an alternative to classic open repair or to a hybrid approach (combining debranching surgery with stent grafting) in an attempt to improve outcomes.

Abstract
Thoracic aortic aneurysms represent a major health problem. Untreated thoracic aortic aneurysms may rupture, which has a dismal outcome. The standard treatment for thoracic aneurysms is open surgical repair, but it is associated with high mortality and morbidity. Endovascular repair provides a less invasive and safer alternative. A systematic review was performed of all published literature on the above subject. Our primary objective was to measure 30-day mortality for nonruptured thoracic aortic aneurysms. Studies describing other pathologies, such as aortic dissection, mycotic aneurysms, penetrating ulcers, traumatic transactions, and pseudoaneurysms, and studies from which independent data for thoracic aortic aneurysm could not be separately extracted were excluded. Case series describing less than 10 patients and all case series describing ruptures or concealed ruptures were excluded as well. Twenty-six case series and one comparative study were identified. This formed a cohort of 1,038 patients. Technical success was possible in more than 97% of patients. The 30-day mortality was calculated to be 5.1% even though the group under study was mostly those who were refused surgery by a surgeon or had a higher surgical risk. The incidence of paraplegia and stroke was 3.1% and 4.7%, respectively. Early endoleak was seen in 16.7% of patients, whereas 11.7% of patients developed late endoleak, but most did not require any additional procedure. The rate of reintervention was 14.9%. The 12-month mortality rate was 14.2%. Endovascular repair shows encouraging short-term results. It is associated with significantly less mortality and morbidity, but long-term results need to be further investigated.

Abstract
PURPOSE To assess 3-dimensional (3D) pulsatile displacement forces (DF) acting on thoracic endografts using 3D computational techniques. METHODS A novel computational method to quantitate the pulsatile 3D flow and pressure fields and aortic wall dynamics in patient-specific anatomical models based on cardiac-gated computed tomography (CT) scans was used to construct simulations of the proximal and mid-descending thoracic aorta. Endografts of varying lengths and diameters were implanted in these patient-specific models. The magnitude and direction of the DF vector were calculated and expressed in Newtons (N). This DF included the effects of both the pressure and shearing stresses of blood. RESULTS The magnitude of DF increased with endografts of increasing diameter and length. A 36-mm endograft in the mid-descending aorta had a mean DF of 21.7 N with a peak systolic DF of 27.8 N and an end-diastolic DF of 16.7 N. Conversely, a 30-mm endograft in the proximal descending aorta had a mean DF of 14.9 N, with peak systolic and end-diastolic DFs of 18.9 and 11.5, respectively. The orientation of the DF acting on the endograft varied depending on aortic angulation and tortuosity; in general, the vector was perpendicular to the greater curvature of the endograft rather than along the downstream longitudinal centerline axis of the aorta as is commonly believed. The DF vector pointed primarily in the cranial direction for the proximal descending endograft and in the sideways direction for the mid-descending endograft simulation. Furthermore, it was shown that elevated pressure plays an important role in the magnitude and direction of DF; an increase in mean blood pressure resulted in an approximately linearly proportional increase in DF. CONCLUSION The orientation of the DF varies depending on curvature and location of the endograft, but in all instances, it is in the cranial rather than caudal direction on axial imaging. This is counter to the intuitive notion that displacement forces act in the downward direction of blood flow. Therefore, we postulate that migration of thoracic endografts may be different from abdominal endografts since it may involve upward rather than downward movement of the graft. Computational methods can enhance the understanding of the magnitude and orientation of the loads experienced in vivo by thoracic aortic endografts and therefore improve their design and performance.

Abstract
Endovascular stent grafts for the treatment of thoracic aortic aneurysms have become increasingly utilized and yet their locational stability in moderate chest trauma is unknown. A high speed impact system was developed to study the stability of aortic endovascular stent grafts in vitro. A straight segment of porcine descending aorta with stent graft was constrained in a custom-made transparent urethane casing. The specimen was tested in a novel impact system at an anterior inclination of 45deg and an average deceleration of 55G, which represented a frontal automobile crash. Due to the shock of the impact, which was shown to be below the threshold of aortic injury, the stent graft moved 0.6mm longitudinally. This result was repeatable. The presented experimental model may be helpful in developing future grafts to withstand moderate shocks experienced in motor vehicle accidents or other dynamic loadings of the chest.

Abstract
An aortoesophageal fistula is uncommon, but almost always fatal. We report a case of an aortoesophageal fistula that developed after stent dilation for an esophageal stricture caused by benign esophagitis. As soon as esophageal hemorrhaging was identified by endoscopy, the patient was transferred to the operating theater; however, the uncontrollable and massive bleeding resulted in pulseless shock. The digestive surgeon put side-clamps on the descending aorta and esophagus and transferred the patient to our hospital. We identified an aortoesophageal fistula, 3.0 mm in diameter, in the descending aorta, and performed a graft replacement of the descending aorta and esophagectomy. It was immediately evident that the edge of the stent had been sticking into the aortic wall, which had caused the fistula. To our knowledge, this is the first report of successful surgical treatment of an aortoesophageal fistula caused by esophageal stent dilatation.

Abstract
BACKGROUND The purpose of this study was to determine durability and need for reinterventions after endovascular stent graft placement in atherosclerotic aneurysms involving the descending aorta. METHODS We performed a prospective follow-up analysis of a consecutive series of 79 patients undergoing endovascular stent graft placement due to atherosclerotic aneurysms involving the descending aorta between 1996 and 2006. Acute aortic syndromes were excluded from this analysis. Mean follow-up was 42 months (range, 1 to 108 months). Data were collected for in-hospital mortality, occurrence of early and late endoleaks, reintervention due to early and late endoleaks, and survival. RESULTS In-hospital mortality was 6.3% (n = 5). Two of these patients underwent emergent treatment. Early type I and III endoleaks were observed in 29% of patients (n = 23). The assisted primary endoleak rate was 11%. Late type I or III endoleaks occurred in 21% (n = 17). At 1, 3, and 5 years, overall actuarial survival was 96%, 86%, and 69%, and event-free survival was 90%, 82%, and 65%, respectively. Cox proportional hazard analysis revealed that a short proximal landing zone and a high number of stent grafts used were independent risk factors for early and late endoleak formation. Late endoleak formation was an independent predictor of survival. CONCLUSIONS Endovascular stent graft placement in atherosclerotic aneurysms involving the descending aorta has satisfactory durability. An extensive landing zone is a prerequisite of early and late success. Further clinical investigations are warranted to evaluate long-term durability of this attractive treatment modality.
