PURPOSE: To report the endovascular treatment of a spontaneous iliac artery dissection (IAD) involving iliac bifurcation, complicated by a type B intramural aortic hematoma (IMH). CASE REPORT: A 38-year-old female patient came to our institution referring an acute ascending back pain. The angioCT-scan showed the presence of a retrograde right IAD with entry tear at the iliac bifurcation and a concomitant aortic IMH. After hypogastric embolization with a vascular plug, self-expanding stent-graft was placed to cover the iliac entry tear...

BACKGROUND: Use of 4-dimensional flow magnetic resonance imaging (4D-flow MRI) derived wall shear stress (WSS) heat maps enables identification of regions in the ascending aorta with increased WSS. These regions are subject to dysregulation of the extracellular matrix and elastic fiber degeneration, which is associated with aortic dilatation and dissection. PURPOSE: To evaluate the effect of the presence of aortic valve stenosis and the aortic diameter on the peak WSS and surface area of increased WSS in the ascending aorta...

" The major goal of surgery for acute type A aortic dissection is to have an alive patient. " This motto still remains the most important directive. However, also depending onto the extent of the underlying pathology and consecutively depending onto the extent of primary surgery, there is and will be need for additional classical surgical or interventional treatment sooner or later during follow-up in a substantial number of patients having had surgery for acute type A aortic dissection. This article shall guide the interested reader through the underlying mechanisms as well as treatment options in patients with chronic type B "residual" after type A repair and shall finally suggest preventive strategies to reduce the occurrence of this pathology to a minimum...

Dilatation of aortic root may distort the tricuspid annulus. We experienced a case of chronic aortic dissection presented with tricuspid regurgitation. Chest computed tomography revealed an enlarged ascending aorta displacing the right heart. The patient successfully underwent replacement of the aorta and tricuspid annuloplasty with a prosthetic annulus.

INTRODUCTION: Coronary artery disease (CAD) not amenable to revascularisation indicates that the coronary arteries have severe diffuse lesions or calcifications, or that CAD is complicated with severe multiple-organ disease. Currently, Western medicines available for the treatment of CAD not amenable to revascularisation are limited. Shexiang Baoxin Pill (SBP), a type of Chinese patent medicine, has been widely used to treat CAD in China for many years. Previous studies have shown that long-term administration of SBP (1-2 pills three times daily, for at least 6 months) for treatment of CAD is effective and safe, with a significant, long-term effect...

Aneurysm-osteoarthritis syndrome is a recently discovered inherited autosomal dominant connective tissue disease caused by SMAD3 mutations. Aneurysm-osteoarthritis syndrome is responsible for 2% of familial thoracic aortic aneurysms and dissections and is characterised by aneurysms, dissections, and tortuosity throughout the arterial tree in combination with osteoarthritis. Early-onset osteoarthritis is present in almost all patients. We present the case of a non-syndromic young boy with SMAD3 mutation isolated from the dilated aortic root and ascending aorta without osteoarthritis...

BACKGROUND AND PURPOSE: A recurrent duplication of chromosome 16p13.1 was associated with aortic dissection as well as with cervical artery dissection. We explore the segregation of this duplication in a family with familial aortic disease. METHODS: Whole exome sequencing (WES) analysis was performed in a patient with a family history of aortic diseases and ischemic stroke due to an aortic dissection extending into both carotid arteries. RESULTS: The index patient, his affected father, and an affected sister of his father carried a large duplication of region 16p13...

Marfan syndrome (MFS) is a genetic disorder that frequently leads to aortic root dissection and aneurysm. Despite promising preclinical and pilot clinical data, a recent large-scale study using antihypertensive angiotensin II (AngII) receptor type 1 (ATR1) blocker losartan has failed to meet expectations at preventing MFS-associated aortic root dilation, casting doubts about optimal therapy. To study the deleterious role of normal ATR1 signaling in aortic root widening, we generated MFS mice lacking ATR1a expression in an attempt to preserve protective ATR2 signaling...

Injuries of the supra-aortic trunk after blunt chest trauma are rare. This is a case report of a blunt traumatic lesion of the innominate artery (IA) origin that exhibited aortic arch involvement with a focus on imaging and treatment. A 41-year-old fisherman presented an IA injury secondary to a high-impact blunt chest trauma. Upon physical examination, vital signs were stable and upper extremity pulses were present. In addition to several bone fractures (costal ribs, clavicle, scapula, temporal, maxillary, and sphenoid), computed tomography angiography revealed dissection/pseudoaneurysm of the IA sparing the bifurcation...

BACKGROUND: Patients with Marfan (MFS) syndrome and patients with a bicuspid aortic valve (BAV) are more prone to develop aortic dilation and dissection compared to persons with a tricuspid aortic valve (TAV). To elucidate potential common as well as distinct pathways of clinical relevance, we compared the histopathological substrates of aortic pathology. PATIENT AND METHODS: Ascending aortic wall specimen were divided in five groups: BAV (n=36) and TAV (n=23) without and with dilation and non-dilated MFS (n=8)...

Total aortic arch replacement remains a technically formidable procedure, particularly in patients with previous proximal aortic dissection repair. Our case discussion highlights a useful strategy for extracorporeal support and circulation management to facilitate total arch reconstruction in the reoperative setting, based on cannulation of the left axillary artery. Our preference is to use a left axillary artery approach to initiate cardiopulmonary bypass and to ultimately revascularize the left arm via an extra-anatomic graft...

We report the case of a patient with mitral regurgitation complicated by type B dissection and Marfan syndrome (MFS) who was managed successfully with minimally invasive mitral valve repair. Without type A aortic dissection or aortic root dilation, MFS patients may develop mitral valve regurgitation, as in this case, and need valve surgery to improve their symptoms and long-term survival. However, it is not clear that a full sternotomy and prophylactic aortic surgery are necessary. Although retrograde perfusion to the dissected aorta is controversial, our approach minimizes the risk of future anticipated aortic surgery in MFS patients...

A 78 year-old man with remote type-A dissection presented with acute-onset dyspnea. Twenty-two years prior, treatment for his aortic disease required replacement of ascending and arch aneurysms with a Dacron graft using graft inclusion technique. He presented currently in cardiogenic shock. Echocardiography demonstrated new severe hypokinesis of all apical segments. Left-heart catheterization revealed a 120mmHg intra-graft gradient. CT arteriography was unrevealing, but intra-aortic ultrasound demonstrated critical intra-graft stenosis...

Residual Type B aortic dissection following open surgical repair of a Type A thoracic aortic dissection- can sometimes be complicated by collateral blood supplies, which can impact existing flow patterns, and result in progressive aneurysmal dilatation of the thoracic false lumens. We report a unique case that describes the clinical presentation of an infrarenal to innominate artery collateral blood flow that complicated a chronic residual type B dissection, which was timely diagnosed using multi-modality imaging, and successfully managed through an innovative minimally-invasive endovascular treatment strategy (without thoracotomy) with no neurological sequela...

Over the past twenty years, the Emergency Department (ED) has transformed from a location that managed patients with acute life-threatening illness or injury to an acute diagnostic center. The advent of rapid and accurate imaging, novel biomarkers, and other innovations concurrent with effects from financial and social forces has supported the development of an acute care system focused on "ruling out" low-frequency, high-mortality events such as acute myocardial infarction, stroke, pulmonary embolism, and aortic dissection...

BACKGROUND: D-dimer shows high sensitivity but low specificity for the diagnosis of acute aortic dissection (AAD). Previous reports indicated that negative D-dimer patients have shorter dissection length. However, whether patients with negative D-dimer results have a good prognosis is unknown. This study aimed to elucidate the clinical characteristics and implications of a negative D-dimer result on AAD diagnosis. METHODS: The study group comprised 126 patients (71 males, 55 females; mean age, 69 ± 11 years) with AAD admitted to our hospital between April 2009 and March 2015...

OBJECTIVES: To report the midterm safety and efficacy of the Aegis™-B (Microport, Shanghai, China) unibody bifurcated stent-graft for endovascular treatment of isolated abdominal aortic dissection (IAAD). BACKGROUND: Isolated abdominal aorta dissection (IAAD) is a rare event. Endovascular stent grafts seem to offer an efficient therapeutic approach to treating IAAD. However, the relatively small diameter of the infrarenal aorta and aortic bifurcation remains the main anatomical limitation to endovascular repair...
