BACKGROUND: Although bovine serum albumin-glutaraldehyde glue (BioGlue®) has been successfully used as a hemostatic adjunct in aortic surgical procedures, there are reports that it may lead to anastomotic pseudoaneurysm formation. We seek to examine if the use of BioGlue is associated with a high incidence of anastomotic pseudoaneurysm formation following surgical repair of thoracic aortic disease. METHODS: We reviewed the medical records and follow-up computed tomography (CT) scans of patients from 2001 to 2015 in whom BioGlue was used during surgical repair of thoracic aortic disease to detect postoperative anastomotic pseudoaneurysm formation...

BACKGROUND: Complex and reverse flow in the aorta has been implicated in aneurysm development and stroke via retrograde embolization. PURPOSE: To evaluate global and regional differences between standard 2D plane-based and volumetric voxel-based quantification of regional forward/reverse flow, and reverse flow fraction (RFF) in the aorta. STUDY TYPE: Retrospective. SUBJECTS: In all, 35 subjects: 10 healthy controls (age: 57 ± 7 years, nine male), nine patients without aortic valve regurgitation (AR) (age: 63 ± 10 years, seven male), six patients with mild AR (age: 66 ± 6 years, five male), and 10 with moderate or severe AR (age: 60 ± 16 years, eight male)...

Fibromuscular dysplasia (FMD) is an idiopathic, segmental, nonatherosclerotic, non-inflammatory vascular disease, which is often complicated by the occurrence of dissection. Although it is known to occur in all arteries, aortic involvement is relatively rare. To date, 33 cases of aortic FMD have been reported in available English literature, among which only three cases have been complicated by the occurrence of dissection. We describe the case of a 40-year-old woman diagnosed with aortic FMD complicated by the occurrence of a type A aortic dissection...

Giant aortic aneurysm is defined as an aneurysm of the aorta of greater than 10 cm in diameter. This rare condition is associated with a high risk of morbidity and mortality and it may lead to fatal complications such as rupture and/or dissection if not managed with proper surgical planning and expertise. Other than atherosclerosis, the main causes of giant ascending aortic aneurysms include Marfan and Ehlers-Danhlos syndromes. Herein we report on a young male patient who had had an aortic valve replacement five years earlier due to a bicuspid aortic valve leading to aortic failure, accompanied by aortic coarctation...

Objective Axillary artery cannulation is still regarded with distrust by surgeons because the artery is supposed to be fragile, difficult to access, and its cannulation is often considered time-consuming. This study was carried out to assess our results in a series of patients, using a simplified surgical approach to axillary artery cannulation. Methods Data were collected retrospectively from our prospective database. All patients operated on in our department between January 2004 and October 2016 and scheduled for various cardiac procedures with direct axillary artery cannulation were included in this study...

We present a comprehensive and original framework for the biomechanical analysis of patients affected by ascending thoracic aorta aneurysm and aortic insufficiency. Our aim is to obtain crucial indications about the role played by deranged hemodynamics on the ATAAs risk of rupture. Computational fluid dynamics analysis was performed using patient-specific geometries and boundary conditions derived from 4D MRI. Blood flow helicity and wall shear stress descriptors were assessed. A bulge inflation test was carried out in vitro on the 4 ATAAs after surgical repair...

A 62-years-old female had undergone ascending aortic replacement with homograft for graft infection and mediastinitis after initial replacement of ascending aorta due to acute type A dissection. Ten years after homograft replacement, follow up computed tomography showed acute growing saccular aneurysm of the homograft without infectious symptoms. We urgently performed Bentall procedure and hemiarch replacement successfully. Pathological diagnosis was true aneurysm of the homograft. She was discharged from hospital without any complication and has been quite uneventful 7 years after surgery...

Quadricuspid aortic valve is a rare congenital disease. We experienced 3 surgical cases of quadricuspid aortic valve. Patient 1 was a 72-year-old man who was noted to have a quadricuspid aortic valve associated with aortic regurgitation and an ascending aortic aneurysm(51 mm in diameter). He underwent replacement of the aortic valve and the ascending aorta. Patient 2 was a 71-year-old man with severe aortic stenosis, regurgitation, and coronary triple vessel disease. He underwent aortic valve replacement and coronary artery bypass grafting...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

BACKGROUND: TEVAR has dramatically expanded treatment options for patients with thoracic aortic pathology. The interaction between endografts and the dynamic anatomy of the thoracic aorta is not well characterized for repetitive physiologic stressors and subsequent issues related to long-term durability. Through 3D modeling we sought to quantify cardiac-induced aortic deformation before and after TEVAR to assess the impact of endografts on dynamic aortic anatomy. METHODS: Eight patients with acute (n = 4) or chronic (n = 3) Type B dissections, or chronic arch aneurysm (n = 1), underwent TEVAR with a single (n = 5) or multiple (n = 3) Gore C-TAG(s)...

Ascending aorta aneurysms (AsAA) are associated with a degeneration of the aortic wall tissue, which leads to changes in tissue mechanical properties. Risk factors for the development of the AsAA disease are recognized in patient age and gender, valve type, hypertension, diabetes mellitus, smoking history, and a prior diagnosis of Marfan syndrome. The present study aims to assess how such clinico-pathological factors can affect the mechanical properties of human dilated ascending aorta. Specimens of AsAA are excised from 68 patients who underwent elective AsAA surgical repair and stretched until rupture during the execution of uniaxial tensile tests...

Accurate assessment of aortic extensibility is a requisite first step for elucidating the pathophysiology of an ascending thoracic aortic aneurysm (ATAA). This study aimed to develop a framework for the in vivo evaluation of the full-field distribution of the aortic wall strain by imaging analysis of electrocardiographic- (ECG) gated thoracic data of 34 patients with ATAA. Seven healthy controls (i.e., non-aneurysmal aorta) from patients who underwent ECG-gated CT angiography for coronary artery diseases were included for comparison...

BACKGROUND: Although open aortic repair (OAR) is still considered to be a standard treatment for thoracic aortic diseases, the indications for thoracic endovascular treatment (TEVAR)/hybrid aortic repair (HAR) have expanded in recent years. The purpose of this study was to review the current status of treatment of thoracic aortic diseases in Japan. METHODS: Data for 2013 and 2014 concerning surgery for diseases of the thoracic/thoracoabdominal aorta were extracted from the Japan Cardiovascular Surgery Database (JCVSD)...

BACKGROUND: The original 'candy-plug' technique has been reported to be beneficial for the treatment of residual perfused false lumen in patients with aortic dissection. However, this technique is also associated with several problems, such as narrowing of the true lumen and damage to the flap or vessel wall. Therefore, we modified the procedure to overcome these problems. Here we report a case in which the patient was successfully treated using the modified procedure. CASE PRESENTATION: A 59-year-old man presented with chronic type B aortic dissection with aneurysmal dilatation...

Aorto-cutaneous fistula and false aneurysm of the ascending aorta in patients who previously underwent Stanford Type A acute aortic dissection are rare and severe complications. Surgical correction remains a demanding challenge. In a case of false aneurysm rupture during redo sternotomy, selective cannulation of the right axillary and left carotid arteries allowed an efficient method of cerebral perfusion.

Thoracic aortic aneurysm (TAA) is a lethal disease, with a natural history of enlarging progressively until dissection or rupture occurs. Since the discovery almost 20 years ago that ascending TAAs are highly familial, our understanding of the genetics of thoracic aortic aneurysm and dissection (TAAD) has increased exponentially. At least 29 genes have been shown to be associated with the development of TAAD, the majority of which encode proteins involved in the extracellular matrix, smooth muscle cell contraction or metabolism, or the transforming growth factor-β signaling pathway...

OBJECTIVE: Endovascular repair of the ascending aorta is currently limited to patients at high surgical risk with aortic diseases originating above the sinotubular junction. A number of different endovascular technologies and approaches have been used, although no consensus exists regarding a standardized technique. To better understand real-world endovascular approaches to the ascending aorta, we performed a comprehensive review of the types of endovascular aortic stents and associated vascular access used in repair of the ascending aorta...

PURPOSE: To present a novel endovascular management option that avoids open surgery in selected patients with subacute type A aortic dissection (DeBakey II). CASE REPORT: A 75-year-old woman with previous infrarenal abdominal aortic aneurysm repaired in 2006 and multiple comorbidities (EURO score II 20.5%) was admitted with chest pain; computed tomography angiography (CTA) showed a new dissection in the ascending aorta just above the right coronary ostium. As the patient was considered unfit to undergo surgery, an endovascular solution was suggested after multidisciplinary team discussion...
