Antegrade cerebral perfusion via the right subclavian artery during open distal arch or proximal descending aortic repair from left thoracotomy.

In the current endovascular era, open surgery through left posterolateral thoracotomy (PLT) with moderate to deep hypothermic circulatory arrest (DHCA) remains an alternative for treating chronic distal arch or proximal descending aortic diseases, allowing cardiovascular surgeons to definitively repair the aorta in a single stage. When utilizing this approach, this report illustrates an alternative surgical technique for antegrade body perfusion during cooling, antegrade selective cerebral perfusion (ASCP), and rewarming, through a prosthetic graft on the right subclavian artery (RSA). This report shows the safety and feasibility of this technique during open distal arch and/or proximal descending aortic surgery through left PLT, after shifting the patient from a supine to the right lateral decubitus position.

National Registry Insights on Genetic Aortopathies and Thoracic Endovascular Aortic Interventions.

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) in patients with genetic aortopathies (GA) is controversial given concerns of durability. We describe characteristics and outcomes following TEVAR in patients with GA. METHODS: All patients undergoing TEVAR between 2010-2023 in the VQI were identified and categorized as having a GA or not. Demographics, baseline, and procedural characteristics were compared among groups. Multivariable logistic regression was used to evaluate the independent association of GA with postoperative outcomes. Kaplan-Meier methods and multivariable Cox-regression analyses were used to evaluate 5-year survival and 2-year reinterventions. RESULTS: Of 19,340 patients, 304 (1.6%) had GA (87% Marfan; 9% Loeys-Dietz; and 4% Vascular Ehlers-Danlos). Compared with non-GA, GA patients were younger (50 [37-72] years vs. 70 [61-77] years), more often presented with acute dissection (28% vs. 18%), post-dissection aneurysm (48% vs. 17%), had symptomatic presentation (50% vs. 39%), and were less likely to have degenerative aneurysms (18% vs. 47%) or PAU [+ IMH] (3% vs. 13%) (all p<.001). GA patients were more likely to have prior repair of the ascending aorta/arch (open: 56% vs. 11%;p<.001; endovascular 5.6% vs. 2.1%;p=.017) or the descending thoracic aorta (open: 12% vs. 2%;p=.007; endovascular 8.2% vs. 3.6%;p=.011). No significant differences were found in prior abdominal suprarenal repairs, however, GA patients had more prior open infrarenal repairs (5.3% vs. 3.2%), but fewer prior endovascular infrarenal repairs (3.3% vs. 5.5%)(all p<.05). After adjusting for demographics, comorbidities, and disease characteristics, patients with GA had similar odds of perioperative mortality (4.6% vs. 7.0%; aOR:1.1 [95%CI: 0.57-1.9];p=.75), any in-hospital complication (26% vs. 23%; aOR:1.24 [0.92-1.6];p=.14), or in-hospital reintervention (13% vs. 8.3%; aOR:1.25 [0.84-1.8];p=.25) compared with non-GA patients. However, GA patients had higher likelihood of post-operative vasopressors (33% vs. 27%; aOR:1.44 [1.1-1.9];p=.006) and transfusion (25% vs. 23%; aOR:1.39 [1.03-1.9]; p=.006). 2-year reintervention rates were higher in GA patients (25% vs. 13%; aHR:1.99 [1.4-2.9];p<.001), but 5-year survival was similar (81% vs. 74%; aHR:1.02 [0.70-1.5];p=.1). CONCLUSIONS: TEVAR for GA patients appeared to be initially safe with similar odds for in-hospital complications, in-hospital reinterventions, and perioperative mortality, as well as similar hazards for 5-year mortality compared with non-GA patients. However, GA patients had higher 2-year reintervention rates. Future studies should assess long-term durability after TEVAR compared with the recommended open repair to appropriately weigh risks and benefits of endovascular treatment in GA patients.

Surgeon volume and outcomes following thoracic endovascular aortic repair for blunt thoracic aortic injury.

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) at high-volume hospitals has previously been associated with lower perioperative mortality, but the impact of annual surgeon volume on outcomes following TEVAR for BTAI remains unknown. METHODS: We analyzed Vascular Quality Initiative (VQI) data from patients with BTAI that underwent TEVAR between 2013 and 2023. Annual surgeon volumes were computed as the number of TEVARs (for any pathology) performed over a 1-year period preceding each procedure and were further categorized into quintiles. Surgeons in the first volume quintile were categorized as low volume (LV), the highest quintile as high volume (HV), and the middle three quintiles as medium volume (MV). TEVAR procedures performed by surgeons with less than 1-year enrollment in the VQI were excluded. Using multilevel logistic regression models, we evaluated associations between surgeon volume and perioperative outcomes, accounting for annual center volumes and adjusting for potential confounders, including aortic injury grade and severity of coexisting injuries. Multilevel models accounted for the nested clustering of patients and surgeons within the same center. Sensitivity analysis excluding patients with grade IV BTAI was performed. RESULTS: We studied 1321 patients who underwent TEVAR for BTAI (28% by LV surgeons [0-1 procedures per year], 52% by MV surgeons [2-8 procedures per year], 20% by HV surgeons [≥9 procedures per year]). With higher surgeon volume, TEVAR was delayed more (in <4 hours: LV: 68%, MV: 54%, HV: 46%; P < .001; elective (>24 hours): LV: 5.1%; MV: 8.9%: HV: 14%), heparin administered more (LV: 80%, MV: 81%, HV: 87%; P = .007), perioperative mortality appears lower (LV: 11%, MV: 7.3%, HV: 6.5%; P = .095), and ischemic/hemorrhagic stroke was lower (LV: 6.5%, MV: 3.6%, HV: 1.5%; P = .006). After adjustment, compared with LV surgeons, higher volume surgeons had lower odds of perioperative mortality (MV: 0.49; 95% confidence interval [CI], 0.25-0.97; P = .039; HV: 0.45; 95% CI, 0.16-1.22; P = .12; MV/HV: 0.50; 95% CI, 0.26-0.96; P = .038) and ischemic/hemorrhagic stroke (MV: 0.38; 95% CI, 0.18-0.81; P = .011; HV: 0.16; 95% CI, 0.04-0.61; P = .008). Sensitivity analysis found lower adjusted odds for perioperative mortality (although not significant) and ischemic/hemorrhagic stroke for higher volume surgeons. CONCLUSIONS: In patients undergoing TEVAR for BTAI, higher surgeon volume is independently associated with lower perioperative mortality and postoperative stroke, regardless of hospital volume. Future studies could elucidate if TEVAR for non-ruptured BTAI might be delayed and allow stabilization, heparinization, and involvement of a higher TEVAR volume surgeon.

Patients' Radiation Exposure During Endovascular Abdominal Aortic Aneurysm Repair.

BACKGROUND: To investigate associations between patient characteristics, intraprocedural complexity factors, and radiation exposure to patients during endovascular abdominal aortic aneurysm repair (EVAR). METHODS: Elective standard EVAR procedures between January 2015 and December 2020 were retrospectively analyzed. Patient characteristics and intraprocedural data (i.e., type of device, endograft configuration, additional procedures, and contralateral gate cannulation time [CGCT]) were collected. Dose area product (DAP) and fluoroscopy time were considered as measurements of radiation exposure. Furthermore, effective dose (ED) and doses to internal organs were calculated using PCXMC 2.0 software. Descriptive statistics, univariable, and multivariable linear regression were applied to investigate predictors of increased radiation exposure. RESULTS: The 99 patients were mostly male (90.9%) with a mean age of 74 ± 7 years. EVAR indications were most frequently abdominal aortic aneurysm (93.9%), penetrating aortic ulceration (2.0%), focal dissection (2.0%), or subacute rupture of infrarenal abdominal aortic aneurysm (2.0%). Median fluoroscopy time was 19.6 minutes (interquartile range [IQR], 14.1-29.4) and median DAP was 86,311 mGy cm2 (IQR, 60,160-130,385). Median ED was 23.2 mSv (IQR, 17.0-34.8) for 93 patients (93.9%). DAP and ED were positively correlated with body mass index (BMI) and CGCT. Kidneys, small intestine, active bone marrow, colon, and stomach were the organs that received the highest equivalent doses during EVAR. Higher DAP and ED values were observed using the Excluder endograft, other bi- and tri-modular endografts, and EVAR with ≥2 additional procedures. Multivariable linear regression analysis revealed that BMI, ≥2 additional procedures during EVAR, and CGCT were independent positive predictors of DAP and ED levels after accounting for endograft type. CONCLUSIONS: Patient-related and procedure-related factors such as BMI, ≥2 additional procedures during EVAR, and CGCT resulted predictors of radiation exposure for patients undergoing EVAR, as quantified by higher DAP and ED levels. The main intraprocedural factor that increased radiation exposure was CGCT. These data can be of importance for better managing radiation exposure during EVAR.

Sex-related Outcomes after Thoracic Endovascular Repair for intact isolated Descending Thoracic Aortic Aneurysm: A Retrospective Cohort Study.

OBJECTIVE: To evaluate the association between sex and outcomes following TEVAR for intact isolated descending thoracic aortic aneurysms (iiDTAA). SUMMARY BACKGROUND DATA: Data regarding sex-related long-term outcomes after TEVAR for iiDTAA are limited and conflicting results regarding perioperative outcomes have been reported. METHODS: We included all TEVAR for iiDTAA between 2014-2019 in the Vascular Quality Initiative linked to Medicare claims, allowing reliable assessment of long-term outcome data. Primary outcomes included 5-year mortality, reinterventions, and ruptures of the thoracic aorta. Secondarily we assessed perioperative outcomes. RESULTS: We identified 685 patients, of which 54% were females. Females had higher aortic size index (females vs. males: 3.31 [IQR, 2.81-3.85] cm/m2 vs. 2.93 [IQR, 2.42-3.36] cm/m2; P<.001), were more frequently symptomatic (31% vs. 20%; P=.001), had longer procedure time (111 [IQR, 72-165] min vs. 97 [IQR, 70-146] min) and more iliac procedures (16% vs. 7.6%; P=.001). Compared with males, females had similar rates of 5-year mortality (58% vs. 53%; HR, 0.93; 95%CI 0.71-1.22; P=.61), reinterventions (39% vs. 30%; HR, 1.12; 95%CI 0.73-1.73; P=.60) and late ruptures (0.6% vs. 1.2%; HR, 0.87; 95%CI 0.12-6.18; P=.89). After adjustment, these outcomes remained similar through 5-years. Furthermore, perioperative mortality was not significantly different between sexes (4.1% vs. 2.2%; P=.25), as were rates of any complication as a composite outcome (16% vs. 21%; P=.16), as well as of individual complications (all P>.05). CONCLUSIONS: Our findings suggest that females who undergo TEVAR for iiDTAA have similar 5-year and perioperative outcomes as compared with males.

Role of Preoperative Embolization in Surgical Management of Carotid Body Tumors: A Systematic Review and Meta-Analysis.

The objective of this study is to evaluate the effect of preoperative embolization on carotid body tumor resection. A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. PubMed, Scopus, and Web of Science were screened for studies published between 2010 and 2022. Primary outcomes investigated were intraoperative blood loss, operative time, length of hospital stay, and perioperative complications such as transient ischemic attack (TIA)/stroke, vascular injury, and cranial nerve injury (CNI). A random effects model was used in cases where study heterogeneity was high. Overall, 25 studies were included in the systematic review, involving 1649 patients: 23 studies were eligible for meta-analysis. The incidence of vascular injury was significantly less in the preoperative embolization group (odds ratio (OR) = 0.60; 95% CI: 0.42-0.84; P = .003). There was no statistically significant difference between the two groups regarding intraoperative blood loss, operative time, length of hospital stay, incidence of TIA/stroke, and CNI. Subgroup analyses did not demonstrate significant difference between Shamblin I, II, and III subgroups regarding operative time. This meta-analysis found preoperative embolization to be significantly beneficial in reducing incidence of vascular injury.

Sex-Specific Morphometric Analysis of Ascending Aorta and Aortic Arch for Planning Thoracic Endovascular Aortic Repair: A Retrospective Cohort Study.

OBJECTIVE: In many studies on aortic disease, women are underrepresented. The present study aims to assess sex-specific morphometric differences and gain more insight into endovascular treatment of the ascending aorta (AA) and arch. METHODS: Electrocardiogram-gated cardiac computed tomography scans of 116 consecutive patients who were evaluated for transcatheter aortic valve replacement were retrospectively reviewed. Measurements of the AA and aortic arch were made in multiplanar views, perpendicular to the semi-automatic centerline. Multiple linear regression analysis was performed to identify predictors affecting AA and aortic arch diameter in men and women. Propensity score matching was used to investigate whether sex influences aortic morphology. RESULTS: In both sexes, body surface area (BSA) was identified as a positive predictor and diabetes as a negative predictor for aortic diameters. In men, age was identified as a positive predictor and smoking as a negative predictor for aortic diameters. Propensity score matching identified 40 pairs. Systolic and diastolic mean diameters and AA length were significantly wider in men. On average, male aortas were 7.4% wider than female aortas, both in systole and diastole. CONCLUSIONS: The present analysis demonstrates that, in women, increased BSA is associated with increased aortic arch diameters, while diabetes is associated with decreased AA and arch diameters. In men, increased BSA and age are associated with increased AA and arch diameters, while smoking and diabetes are associated with decreased AA and arch diameters. Men were confirmed to have 7.4% greater AA and arch diameters than women. CLINICAL IMPACT: Men had 7.4% greater ascending aorta and arch diameters than women in a retrospective cohort, gated computed tomography-based study of 116 patients. Sex-specific differences in ascending aortic and arch size should be considered by aortic endovascular device manufacturers and physicians when developing ascending and arch endografts and planning aortic interventions.

Vascular Access Challenges in Thoracic Endovascular Aortic Repair: A Literature Review.

BACKGROUND: This review aims to comprehensively summarize access challenges in thoracic endovascular aortic repair (TEVAR) by describing vascular access routes, associated risks, outcomes, and complications. METHODS: A literature search was conducted utilizing the PubMed (Medline), Scopus, and Web of Science databases. Qualitative and quantitative data from selected studies are extracted and discussed according to available standards for narrative reviews. RESULTS: In total, there were 109 eligible studies based on predefined inclusion- and exclusion criteria. There were 39 original articles or reviews and 57 case series or case reports. This article summarizes the evidence from these studies and discusses traditional retrograde access routes and techniques for TEVAR via a femoral or iliac route, with or without the use of conduits. Next, alternative antegrade access routes and techniques via a brachial, axillary, carotid, ascending aorta, transapical, transcaval, or another route are discussed. Vascular access complications are presented with specific attention to the importance of gender and alternative antegrade access routes. CONCLUSIONS: Multiple access routes and techniques are currently available to overcome access challenges associated with TEVAR, based on low grade evidence from heterogeneous studies. Future research that compares different access routes and techniques might help in the development of a tailored access protocol for specific patients with challenging TEVAR access.

Utilizing numerical simulations to prevent stent graft kinking during thoracic endovascular aortic repair.

Numerical simulations of thoracic endovascular aortic repair (TEVAR) may be implemented in the preoperative workflow if credible and reliable. We present the application of a TEVAR simulation methodology to an 82-year-old woman with a penetrating atherosclerotic ulcer in the left hemiarch, that underwent a left common carotid artery to left subclavian artery bypass and consequent TEVAR in zone 2. During the intervention, kinking of the distal thoracic stent graft occurred and the simulation was able to reproduce this event. This report highlights the potential and reliability of TEVAR simulations to predict perioperative adverse events and short-term postoperative technical results.

Twenty-five years of observations from the International Registry of Acute Aortic Dissection (IRAD) and its impact on the cardiovascular scientific community.

OBJECTIVE: The International Registry of Acute Aortic Dissection (IRAD) celebrated its 25th anniversary in January 2021. This study evaluated IRAD's role in promoting the understanding and management of acute aortic dissection (AD) over these years. METHODS: IRAD studies were identified, analyzed, and ranked according to their citations per year (c/y) to determine the most-cited IRAD studies and topics. A systematic search of the literature identified cardiovascular guidelines on the diagnosis and management of acute AD. Consequently, IRAD's presence and impact were quantified using these documents. RESULTS: Ninety-seven IRAD studies were identified, of which 82 obtained more than 10 cumulative citations. The median c/y index was 7.33 (25th-75th percentile, 4.01-16.65). Forty-two studies had a greater than median c/y index and were considered most impactful. Of these studies, most investigated both type A and type B AD (n = 17, 40.5%) and short-term outcomes (n = 26, 61.9%). Nineteen guideline documents were identified from 26 cardiovascular societies located in Northern America, Europe, and Japan. Sixty-nine IRAD studies were cited by these guidelines, including 38 of the 42 most-impactful IRAD studies. Among them, partial thrombosis of the false lumen as a predictor of postdischarge mortality and aortic diameters as a predictor of type A occurrence were determined as most-impactful specific IRAD topics by their c/y index. CONCLUSIONS: IRAD has had and continues to have an important role in providing observations, credible knowledge, and research questions to improve the outcomes of patients with acute AD.

Editor's Choice - Comparison of the Reproducibility of Ultrasound Calliper Placement Methods in Abdominal Aortic Diameter Measurements: A Systematic Review and Meta-Analysis of Diagnostic Test Accuracy Studies.

OBJECTIVE: To assess which ultrasound (US) method of maximum anteroposterior (AP) abdominal aortic diameter measurement can be considered most reproducible. DATA SOURCES: MEDLINE, Scopus, and Web of Science were searched (PROSPERO ID: 276694). Eligible studies reported intra- and or interobserver agreement according to Bland-Altman analysis (mean ± standard deviation [SD]) for abdominal aortic diameter AP US evaluations with an outer to outer (OTO), inner to inner (ITI), and or leading edge to leading edge (LELE) calliper placement. REVIEW METHODS: The Preferred Reporting Items for a Systematic Review and Meta-Analysis of Diagnostic Test Accuracy Studies statement was followed. The QUADAS-2 tool and QUADAS-C extension were used for risk of bias assessment and the GRADE framework to rate the certainty of evidence. Pooled estimates (fixed effects meta-analysis, after a test of homogeneity of means) for each US method were compared with pairwise one sided t tests. Sensitivity analyses (for studies published in 2010 or later) and meta-regression were also performed. RESULTS: 21 studies were included in the qualitative analysis. Twelve were eligible for quantitative analysis. Studies showed heterogeneity in the US model and transducer used, sex of participants, and observer professions, expertise, and training. Included studies shared a common mean for each US method (OTO: p = 1.0, ITI: p = 1.0, and LELE: p = 1.0). A pooled estimate of interobserver reproducibility for each US method was obtained, combining the mean ± SD (Bland-Altman analysis) from each study: OTO: 0.182 ± 0.440; ITI: 0.170 ± 0.554; and LELE: 0.437 ± 0.419. There were no statistically significant differences between the methods (OTO vs. ITI: p = .52, OTO vs. LELE: p = .069, ITI vs. LELE: p = .17). Considering studies published in 2010 and later, the pooled estimate for LELE was the smallest, without statistically significant differences between the methods. Despite the low risk of bias, the certainty of the evidence for both meta-analysed outcomes remained low. CONCLUSION: The interobserver reproducibility for OTO and ITI was 2.5 times smaller (indicating better reproducibility) than LELE; however, without statistically significant differences between the methods and low GRADE evidence certainty. Additional data are needed to validate these findings, while inherent differences between the methods need to be emphasised.

Thoracic Stent Graft Numerical Models To Virtually Simulate Thoracic Endovascular Aortic Repair: A Scoping Review.

OBJECTIVE: Pre-procedural planning of thoracic endovascular aortic repair (TEVAR) may implement computational adjuncts to predict technical and clinical outcomes. The aim of this scoping review was to explore the currently available TEVAR procedure and stent graft modelling options. DATA SOURCES: PubMed (MEDLINE), Scopus, and Web of Science were systematically searched (English language, up to 9 December 2022) for studies presenting a virtual thoracic stent graft model or TEVAR simulation. REVIEW METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) was followed. Qualitative and quantitative data were extracted, compared, grouped, and described. Quality assessment was performed using a 16 item rating rubric. RESULTS: Fourteen studies were included. Among the currently available in silico simulations of TEVAR, severe heterogeneity exists in study characteristics, methodological details, and evaluated outcomes. Ten studies (71.4%) were published during the last five years. Eleven studies (78.6%) included heterogeneous clinical data to reconstruct patient specific aortic anatomy and disease (e.g., type B aortic dissection, thoracic aortic aneurysm) from computed tomography angiography imaging. Three studies (21.4%) constructed idealised aortic models with literature input. The applied numerical methods consisted of computational fluid dynamics analysing aortic haemodynamics in three studies (21.4%) and finite element analysis analysing structural mechanics in the others (78.6%), including or excluding aortic wall mechanical properties. The thoracic stent graft was modelled as two separate components (e.g., graft, nitinol) in 10 studies (71.4%), as a one component homogenised approximation (n = 3, 21.4%), or including nitinol rings only (n = 1, 7.1%). Other simulation components included the catheter for virtual TEVAR deployment and numerous outcomes (e.g., Von Mises stresses, stent graft apposition, drag forces) were evaluated. CONCLUSION: This scoping review identified 14 severely heterogeneous TEVAR simulation models, mostly of intermediate quality. The review concludes there is a need for continuous collaborative efforts to improve the homogeneity, credibility, and reliability of TEVAR simulations.

Acute venous problems: Integrating medical, surgical, and interventional treatments.

"Acute venous problems" refers to a group of disorders that affect the veins and result in sudden and severe symptoms. They can be classified based on the pathological triggering mechanisms, such as thrombosis and/or mechanical compression, and their consequences, including symptoms, signs, and complications. The management and therapeutic approach depend on the severity of the disease, the location, and the involvement of the vein segment. Although summarizing these conditions can be challenging, the objective of this narrative review was to provide an overview of the most common acute venous problems. This will include an exhaustive yet concise and practical description of each condition. The multidisciplinary approach remains one of the major advantages in dealing with these conditions, maximizing the results and the prevention of complications.

Five-year sex-related outcomes of thoracic endovascular aortic repair in the Global Registry for Endovascular Aortic Treatment.

OBJECTIVE: The impact of sex on outcomes of thoracic endovascular aortic repair (TEVAR) represents an area of increased interest over the last decade, and long-term data are lacking. The aim of the present study was to investigate sex-related differences in long-term outcomes after TEVAR using real-world data from the Global Registry for Endovascular Aortic Treatment. METHODS: Data were obtained retrospectively after querying the multicenter, sponsored Global Registry for Endovascular Aortic Treatment. Patients treated with TEVAR between December 2010 and January 2021 were selected regardless of the type of thoracic aortic disease. The primary outcome was sex-specific all-cause mortality at 5 years and maximum follow-up. Secondary outcomes were sex-specific all-cause mortality at 30 days and 1 year, and aorta-related mortality, major adverse cardiac events, neurological complications, and device-related complications or reinterventions at 30 days, 1 year, 5 years, and maximum follow-up. RESULTS: A total of 805 patients were analyzed; 535 (66.5%) were males. Females were older (median, 66 years [interquartile range (IQR), 57-75 years] vs 69 years [IQR, 59-78 years], P < .001). Males had more frequently a history of coronary artery bypass grafting and renal insufficiency (8.7% vs 3.7% [P = .010] and 22.4% vs 11.6% [P < .001]). The median follow-up was 3.46 years (IQR, 1.49-4.99 years) for males and 3.18 years (IQR, 1.29-4.86 years) for females. Indications for TEVAR were mostly descending thoracic aortic aneurysms (n = 307 [38.1%]) type B aortic dissections (n = 250 [31.1%]) or others (n = 248 [30.8%]). Freedom from 5-year all-cause mortality was similar for males and females (67% [95% CI, 62.1-72.2] vs 65.9% [95% CI, 58.5-74.2]; P = .847), and there were no differences in secondary outcomes. Multivariable Cox regression showed females to have lower all-cause mortality rates; however, this difference did not reach statistical significance (hazard ratio, 0.97; 95% CI, 0.72-1.30; P = .834). Additional subgroup analyses based on the indication for TEVAR did not identify differences between both sexes for the primary and secondary outcomes except more endoleak type II in females with complicated type B aortic dissection (1.8% vs 12.1%; P = .023). CONCLUSIONS: The present analysis suggests that long-term outcomes of TEVAR performed irrespective of the type of aortic disease are similar for males and females. Further studies are needed to clarify existing controversies regarding the impact of sex on outcomes of TEVAR.

Endovascular Intervention for Aortic Dissection Is "Ascending".

Ascending aorta diseases represent an important cause of mortality worldwide. Notably, acute and chronic thoracic aorta pathologies have increased during the last years, but medical therapy does not seem to influence their natural history. Currently, although open surgery is the first choice of treatment, many patients are still rejected or have poor outcomes. In this scenario, endovascular treatment is raised as a valuable option. In this review we describe the limitations of conventional surgery and the state-of-art of endovascular ascending aorta repair.
