Project description:BackgroundFor the management of descending thoracic aortic aneurysms, recent evidence has suggested that outcomes of open surgical repair may surpass thoracic endovascular aortic repair (TEVAR) in as early as 2 years.ObjectivesThe purpose of this study was to evaluate the comparative effectiveness of TEVAR and open surgical repair in the treatment of intact descending thoracic aortic aneurysms.MethodsUsing the Medicare database, a retrospective study using regression discontinuity design and propensity score matching was performed on patients with intact descending thoracic aortic aneurysms who underwent TEVAR or open surgical repair between 1999 and 2010 with follow-up through 2014. Survival was assessed with restricted mean survival time. Perioperative mortality was assessed with logistic regression. Reintervention was evaluated as a secondary outcome.ResultsMatching created comparable groups with 1,235 open surgical repair patients matched to 2,470 TEVAR patients. The odds of perioperative mortality were greater for open surgical repair: high-volume center, odds ratio (OR): 1.97 (95% confidence interval [CI]: 1.53 to 2.61); low-volume center, OR: 3.62 (95% CI: 2.88 to 4.51). The restricted mean survival time difference favored TEVAR at 9 years, -209.2 days (95% CI: -298.7 to -119.7 days; p < 0.001) for open surgical repair. Risk of reintervention was lower for open surgical repair, hazard ratio: 0.40 (95% CI: 0.34 to 0.60; p < 0.001).ConclusionsOpen surgical repair was associated with increased odds of early postoperative mortality but reduced late hazard of death. Despite the late advantage of open repair, mean survival was superior for TEVAR. TEVAR should be considered the first line for repair of intact descending thoracic aortic aneurysms in Medicare beneficiaries.

Project description:Background Penetrating ulcers of aorta, aortic dissections and intramural hematomas all come under acute aortic syndromes and have important similarities and differences. Case report We report a 67?year old man with rupture of a large penetrating ulcer of the distal ascending aorta with hemopericardium and left hemothorax. He underwent interposition graft replacement of ascending aorta and hemi-arch with a 30?mm Gelweave Vascutek graft but represented 6?months later with development of a penetrating ulcer which ruptured into a huge 14?cm pseudoaneurysm. This was repaired with a 28?mm Vascutek Gelseal graft replacement of arch and interposition graft reconstruction of innominate and left common carotid arteries. 6?weeks later, however, he ruptured his proximal descending aorta and underwent TEVAR satisfactorily. Unfortunately, 2?days later, he developed a pathological fracture of left proximal tibia with metastasis from a primary renal cell carcinoma. He died 3?weeks later from respiratory failure. We shall briefly outline the similarities and differences in presentation and management of penetrating aortic ulcers, aortic dissections and intramural haematomas. We shall discuss, in greater detail, penetrating ulcers of thoracic aorta, their natural history, location, complications and management. Conclusion This case report is unique on account of initial successful surgical redressal following rupture of penetrating ulcer of distal ascending aorta into left pleural and pericardial cavities, normally associated with instant death. The haemodynamic effects of the rupture were staggered due to initial contained rupture into a smaller pseudoaneurysm, followed by a further rupture into a false aneurysmal sac followed eventually by generalised rupture into the pleural and pericardial cavities - a unique way of aortic rupture. Further development of another penetrating ulcer and a small pseudoaneurysm in the distal arch 6?months later which further ruptured into a larger 14?cm false aneurysmal sac, which again did not result in exsanguination, is again extraordinarily rare. Thereafter he underwent emergency thoracic endovascular aortic repair (TEVAR) for a further rupture of descending thoracic aorta. All three ruptures were managed successfully and would usually be associated with near-certain death, only for the patient to succumb eventually to the complications of metastatic renal cell carcinoma.

Project description:Objective: The optimal treatment modality for retrograde type A intramural hematoma (IMH) remains debatable. This study evaluated and compared surgical outcomes and aortic remodeling after open aortic repair and thoracic endovascular aortic repair (TEVAR) in patients with retrograde type A IMH with a primary intimal tear or ulcer like projection in the descending aorta. Methods: A single center, retrospective observational study was performed on patients with retrograde type A IMH undergoing either open aortic repair and TEVAR. From June 2009 and November 2019, 46 patients with retrograde type A IMH who received either open aortic repair or TEVAR at our institution were reviewed for clinical outcomes, including post-operative mortality/morbidity, re-intervention rate and aortic remodeling. Results: 33 patients underwent open aortic repair and 13 underwent TEVAR. Median age was 68 years (interquartile range [IQR] 15.2 years) and 63 years (IQR 22.5 years) for the open repair group and TEVAR group, respectively. The median duration of follow-up for TEVAR patients was 37.6 months and 40.3 months for open aortic repair. No difference in the 5-year estimated freedom from all-cause mortality (82.1 vs. 87.8%, p = 0.34), re-intervention (82.5 vs. 93.8%, p = 0.08), and aortic-related mortality (88.9 vs. 90.9%, p = 0.88) were observed between the TEVAR and open repair group, respectively; however, the open repair group had a significantly higher 30-day composite morbidity (39.4 vs. 7.7%, p = 0.037). All patients from both treatment groups had complete resolution of the IMH in the ascending aorta. With regard to the descending thoracic aorta, TEVAR group had a significantly greater regression in the diameter of the false lumen or IMH thickness when compared to the open repair group [median 14mm (IQR 10.1) vs. 5mm (IQR 9.5), p < 0.001]. Conclusion: TEVAR and open aortic repair were both effective treatments for retrograde type A IMH, in which no residual ascending aortic IMH was observed during follow-up. TEVAR was also associated with lower post-operative composite morbidities and better descending aortic remodeling. In selected patients with retrograde type A IMH, TEVAR might be a safe, effective alternative treatment modality.

Project description:Extensive thoracic aortic disease involving the ascending aorta, the aortic arch, and the descending thoracic aorta may require multiple surgical and interventional managements, which impose a burden in terms of cumulative surgical trauma and the risk of interval mortality. Herein, we describe a single-stage arch and descending thoracic aorta replacement via sternotomy in a patient with multiple comorbidities presenting with an extensive thoracic aortic aneurysm.

Project description:Pulmonary vein obstruction is rare condition characterized by challenging diagnosis and unfavorable prognosis at advanced stage. Computerized tomography, magnetic resonance imaging, and transesophageal echocardiography (TEE) are often essential to reach a final diagnosis. External compression of pulmonary vein resulting from the mass effect of pseudoaneurysm and perianeurysmal hematoma due to aortic transection is extremely rare. We describe a case of traumatic transection of descending thoracic aorta where TEE was instrumental in the diagnosis of left upper pulmonary vein obstruction and help in the modification of the surgical plan.

Project description:BackgroundReports on the residual descending aortic dissection (AD) after acute type A AD (TAAD) repair has been limited. Therefore, we evaluated the fate of descending aorta in patients who underwent acute TAAD repair.MethodsWe reviewed 299 patients (mean: 60.4 years, 51.5% male) patients who received acute TAAD repair between 2009 and 2018, except genetic aortopathy and concomitant surgeries for the descending aorta. Subjects are categorized into classic TAAD (Classic, n=226), retrograde extension of TAAD from the intimal tear in the descending aorta (Retro, n=31), and intramural hematoma (IMH, n=42) types of AD. Interested outcome was expansion rate of descending aorta. Secondary outcome was descending aorta events including surgical repair, interventions, and aortic rupture. To reduce selection bias, baseline variables were adjusted. Multivariable risk analyses were performed to find risk factors of the study outcomes.ResultsIn crude analysis, descending aorta in Retro [beta, 2.260; standard error (SE), 0.559] and Classic (beta, 1.542; SE, 0.233) groups expanded faster than IMH (beta, 0.443; SE, 0.491) group. Unadjusted risk of aortic event was significantly higher in the Retro group compared with the IMH [hazard ratio (HR) =4.80; 95% confidence interval (CI): 1.56-14.7] and Classic (HR =2.36; 95% CI: 1.24-4.49) groups. Baseline adjustment did not alter these findings. In multivariable analyses, the presence of intimal tear in the upper thoracic descending aorta (above 7th thoracic vertebra) was significantly associated with the aortic expansion (beta, 2.06; SE, 0.61) and events (HR =8.74; 95% CI: 4.34-17.6).ConclusionsThe descending aorta growth was faster in Retro and Classic than IMH and related with the tear location. Careful assessment on the descending is warranted.

Project description:BackgroundMost blunt aortic injuries occur in the proximal proximal descending aorta causing acute transection of this vessel. Generally, surgical repair of the ruptured segment of aorta is associated with high rates of morbidity and mortality and in this view endovascular treatment seems to be a valid and safer alternative. Aim of this article is to review our experience with endovascular approach for the treatment of acute traumatic rupture of descending thoracic aorta.MethodsFrom April 2002 to November 2014, 11 patients (9 males and 2 females) were referred to our Department with a diagnosis of acute transection of thoracic aorta. Following preoperative Computed Tomography (CT) evaluation, thoracic endovascular aortic repair (TEVAR) with left subclavian artery coverage was performed. Follow-up consisted clinical and instrumental (CT, Duplex ultrasound) controls at discharge, 1, 3 and 6 months and yearly thereafter.ResultsAt 12-year follow up, the overall survival for the entire patients cohort was 100 %, no major or minor neurological complications and no episode of left arm claudication occurred. Cardiovascular, respiratory and bleeding complications, in the early period, was represented by minor, non fatal events. No stent graft failure, collapse, leak or distal migration were detected at CT scan during the entire follow up period.ConclusionsAccording to our experience, despite the small number of patient population, TEVAR procedure with with left subclavian artery coverage, performed in emergency settings, seems to provide excellent long term results.Trials registrationThe protocol was registered at a public trials registry, www.clinicaltrials.gov (trial identifier NCT02376998 ).

Project description:IntroductionIn patients with ascending aortic (AA) aneurysms, prosthetic graft replacement yields benefit but risk for complications in the descending aorta persists. Longitudinal impact of AA grafts on native descending aortic physiology is poorly understood.MethodsTransthoracic echocardiograms (echo) in patients undergoing AA elective surgical grafting were analyzed: Descending aortic deformation indices included global circumferential strain (GCS), time to peak (TTP) strain, and fractional area change (FAC). Computed tomography (CT) was used to assess aortic wall thickness and calcification.Results46 patients undergoing AA grafting were studied; 65% had congenital or genetically-associated AA (30% bicuspid valve, 22% Marfan, 13% other): After grafting (6.4±7.5 months), native descending aortic distension increased, irrespective of whether assessed based on circumferential strain or area-based methods (both p<0.001). Increased distensibility paralleled altered kinetics, as evidenced by decreased time to peak strain (p = 0.01) and increased velocity (p = 0.002). Augmented distensibility and flow velocity occurred despite similar pre- and post-graft blood pressure and medications (all p = NS), and was independent of pre-surgical aortic regurgitation or change in left ventricular stroke volume (both p = NS). Magnitude of change in GCS and FAC was 5-10 fold greater among patients with congenital or genetically associated AA vs. degenerative AA (p<0.001), paralleling larger descending aortic size, greater wall thickness, and higher prevalence of calcific atherosclerotic plaque in the degenerative group (all p<0.05). In multivariate analysis, congenital/genetically associated AA etiology conferred a 4-fold increment in magnitude of augmented native descending aortic strain after proximal grafting (B = 4.19 [CI 1.6, 6.8]; p = 0.002) independent of age and descending aortic size.ConclusionsProsthetic graft replacement of the ascending aorta increases magnitude and rapidity of distal aortic distension. Graft effects are greatest with congenital or genetically associated AA, providing a potential mechanism for increased energy transmission to the native descending aorta and adverse post-surgical aortic remodeling.
