INTRODUCTION: Double aortic arch is a congenital vascular abnormality in which the connected segments and their branches course between and compress the trachea and esophagus, often resulting in invariable airway compression. CASE PRESENTATION: A 4-year-old boy with a history of recurrent wheezing was admitted to our hospital for evaluation of asthma based on his past medical history, persistent cough, wheezing, and airway hyperresponsiveness by lung function test...

BACKGROUND: The study sought to evaluate if a bovine aortic arch (BAA) influences the location of the entry site in acute aortic dissection type A (AADA) and to identify the impact of BAA on postoperative outcome, especially stroke. METHODS: A total of 315 patients underwent surgery due to AADA DeBakey type I (72.1% men, mean age 59.5 ± 13.4 years) between 2002 and 2015. Imaging studies and operative reports were screened for presence of BAA and location of the entry site...

GPR116 (ADGRF5) and ELTD1 (ADGRL4) belong to different subfamilies of the adhesion G-protein-coupled receptor group but are both expressed in endothelial cells. We therefore analyzed their functions in mice lacking these receptors. While loss of GPR116 or ELTD1 alone had no obvious effect on cardiovascular or kidney function, mice lacking both, GPR116 and ELTD1, showed malformations of the aortic arch arteries and the cardiac outflow tract leading to perinatal lethality in about 50% of the mutants. In addition to cardiovascular malformations, surviving mice developed renal thrombotic microangiopathy as well as hemolysis and splenomegaly, and their lifespan was significantly reduced...

Injury and endothelial cell apoptosis are hall marks of atherosclerosis (AS). However, the mechanisms underlying its pathogenesis remain ill-defined. Recent evidence of a role for microRNAs in AS-associated endothelial cell apoptosis encouraged us to address this question. Here, AS was developed in ApoE (-/-) mice supplied with a high-fat diet (HFD), compared to ApoE (-/-) mice supplied with a normal diet (ND). Mouse endothelial cells were isolated from the aortic arch using flow cytometry based on their expression of CD31...

Aortic dissection is diagnostically challenging, especially in pain-free patients. Detection of acute ischemic stroke secondary to painless aortic dissection is a challenge for emergency physicians and neurologists. We report a previously healthy 58-years old female, admitted because of nausea, dizziness, somnolence, a left-sided hemiparesis and arterial hypotension. The electrocardiogram showed atrial fibrillation with ST-elevations and ST-depressions. Perfusion CT-imaging showed a dilatation of the aortic arch and intraluminal structures indicating an intima flap of aortic dissection...

OBJECTIVES: We sought to evaluate outcomes of stent implantation (SI) for recurrent coarctation of the aorta (RC) following the Norwood operation. BACKGROUND: RC is common following the Norwood operation. Balloon angioplasty (BA) is standard treatment but may result in unsatisfactory relief of RC. SI may improve RC, but outcome data are limited. METHODS: We performed a multi-center retrospective study of patients who underwent SI for RC between the Norwood operation and Fontan completion...

OBJECTIVE: The use of the frozen elephant trunk (FET) technique for repair of type A aortic dissection (TAAD) in Marfan syndrome (MFS) is controversial. We seek to evaluate the efficacy of FET and total arch replacement (TAR) for TAAD in patients with MFS. METHODS: The early and long-term outcomes were analyzed for 106 patients with MFS (mean age, 34.5 ± 9.7 years) undergoing FET + TAR for TAAD. RESULTS: Operative mortality was 6.6% (7 of 106)...

BACKGROUND AND AIM: Concomitant endovascular stent grafting of the descending thoracic aorta during open repair for acute DeBakey I aortic dissection can be performed in patients with extensive dissection and malperfusion. We analyzed the effects of this strategy on distal aortic remodeling. METHODS: From 2006-2014, acute DeBakey I dissection patients without primary aortic arch tear undergoing open distal hemiarch reconstruction (Standard group) versus those undergoing hemiarch with descending thoracic aorta (DTA) thoracic endovascular aortic repair (TEVAR group) were retrospectively reviewed...

A 27-year-old man was admitted with a penetrating injury at the mid-manubrium. Computed tomographic (CT) angiography showed a filling defect in the aortic arch. This was evaluated as a sign of injury and the patient underwent an emergency operation. No active bleeding or clot was found in the mediastinum during the operation. The laceration point was between the innominate and the left carotid artery posteriorly. The injury was approached using hypothermic circulatory arrest. Aortotomy and exploration showed a 2-cm-long full-thickness aortic injury with an overlying clot...

Although short and long-term outcomes of aortic surgeries have been improving over the past decade, the procedure is likely to be asscociated with life-threatening complications such as neurological deficits caused by suboptimal brain protection or heavily diseased aorta. Contemporary strategies for brain protection are deep hypothermic arrest with or without retrograde cerebral perfusion retrograde cerebral perfusion or selective antegrade cerebral perfusion. At the moment, majority of evidences failed to show the superiority of selective antegrade cerebral perfusion to retrograde one...

A 66-year-old man developed an extended chronic type B dissection involving the thoraco-abdominal aorta with a large entry at the aortic arch and a patent false lumen. We performed triple-stage endovascular repair which included the vascular plug, endovascular aortic repair and hybrid thoracic endovascular aortic repair. His postoperative course was uneventful and the false lumen was finally thrombosed.

A 77-year-old man, who had been under medical treatment for myasthenia gravis without thymoma, was diagnosed with aortic arch aneurysm. He underwent total aortic arch replacement and total resection of the thymus through median sternotomy. His symptoms relating to myasthenia gravis dramatically disappeared after the surgery. The serum anti-acetyl chorine receptor antibody decreased from 2.7 to 0.7 nmol/l (N<0.2) with the reduction of oral predonisolone from 12.5 to 5 mg/day at 4 years after the surgery. The concomitant operations significantly improved his quality of life...

Stroke is a life threatening event that is expected to more than double over the next 40 years. Atrial fibrillation (AF) has been reported as a strong independent risk factor for stroke. We have previously shown that a hemodynamic perturbation by AF or reduced cardiac output and cycle length may have a significant impact on clot trajectory and thus embolic stroke propensity through the left common carotid artery using an idealized aortic arch model. Here, we show the dependence of flow patterns and hence stroke propensity on geometry of patient-specific aortas...
