Aortic dissection with intimal flap noted in the thoracic aorta commencing just distal to the subclavian artery branch point extending down to the T10 level.Conclusion. Type B aortic aneurysmal dissection with intimal flap seen extending to the T10 level. Data from 63 studies published from 2006 to 2012 were retrieved for a total of 1,548 patients treated medically, 1,706 patients who underwent open surgery, and 3,457 patients who underwent thoracic endovascular repair (TEVAR). For acute (rst 2 weeks) type B aortic dissection Type B dissection usually starts with a primary intimal tear in the descending thoracic aorta just distal to the origin of left subclavian artery. This type constitutes approximately 25 of all aortic dissections. A Computed Tomography Angiography (CTA) was done which confirmed thoracic aortic dissection (Stanford type B) (Figures 1 and 2). An uneventful endovascular stent graft with Captivia system was done to contain the entry tear. Objectives: We aimed to determine the key factors associated with successful early and late outcomes after thoracic endovascular aortic repair (TEVAR) for non-acute Stanford type B aortic dissection at our institution. In this roundtable discussion originally posted on Medscape Cardiology, Mayo Clinic Cardiology, Cardiac Surgery, and Vascular Surgery specialists Robert D Describe the features that render a Stanford type B dissection complicated. Introduction. Thoracic aortic dissection should be considered for every patient presenting to the emergency department with chest pain or back pain, particularly if accompanied by neurologic signs or symptoms. in aortic morphology (expanding diameter 4 mm, new onset of periaortic hematoma, and/or pleural hemorrhagic effusion) Refractory hypertension Recurrent thoracic pain Malperfusion SUBACUTE TYPE B AORTIC DISSECTION. Medical therapy has been the mainstay of treatment for uncomplicated Stanford type B aortic dissection for many years 1. However, more recently, endovascular aortic stenting of dissecting thoracic aneurysm has also become a well recognised treatment option 2 (b) Type B—confined to the descending thoracic aorta (30 to 40).

Uncomplicated type B aortic dissection (AD): OMT with control of blood pressure (goal systolic blood pressure 100 to 120 mm Hg), heart rate (goal <60 beats per minute), and pain. While acute thoracic aortic dissection can represent a source of major morbidity and mortality, prompt recognition in the emergency department can improve patient outcomes.Image 2.

Thoracic aortic replacement in type-B aortic dissections: midterm results.Replacement of the thoracic aorta was performed in 29 patients with a diagnosis of type-B aortic dissection between 1996 and 2003. Aortic dissection (AD) occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart. In most cases this is associated with a sudden onset of severe chest or back pain, often described as "tearing" in character. Keywords: thoracic aortic dissection, thrombosis, aneurysm 1.

Moll, MD, PhD2, Joost A The primary endpoint of the Medtronic Dissection trial was to evaluate the safety of the Valiant Thoracic Stent Graft with the Captivia Delivery System in the treatment of acute, complicated Type B thoracic aortic dissections subjects, determined by the rate of Thoracic aortic dissections (TAD) are a bit of a nightmare.This is important, as the treatment of this condition will depend on the classification, type A requiring emergency surgical repair and type B being treated initially with medical therapy (Braverman 2010). Thoracic aortic disease, for the purpose of this GeneReview, refers to thoracic aortic aneurysms and aortic dissections (TAAD).Type B aortic dissections tend to be less likely to result in death and to occur with little to no enlargement of the descending aorta. Type B aortic dissection (TBAD) comprises approximately one third of all acute aortic dissections with management of this disease undergoing revolutionary changes since the introduction of thoracic endovascular aortic repair (TEVAR) (1) emergency thoracic aortic stent grafting for patients with complicated acute type B aortic dissection has played a bigger and bigger role (see Chapter 72) along with catheter interventional flap fenestration and true lumen bare metal stenting to relieve distal malperfusion. Stanford type B aortic dissection (TBAD) is a life-threatening vascular disease, with a 5-year mortality of about 3040.13 It is caused by a tear in the intimal layer of the descending thoracic aorta, which allows blood flow between the intima and media, resulting in a separation of these layers. Type A aortic dissection involves the ascending thoracic aorta and may extend into the descending aorta, whereas in a type B dissection the intimal tear is located distal to the left subclavian artery. Although plain film chest radiograph may be used to screen for a widened mediastinum (Image A) which suggests thoracic aortic dissection, computedphysiology.1 Type A dissection requires immediate surgical intervention.

Class IIa. 1. Computed tomographic imaging or magnetic reso-nance imaging of the thoracic aorta is reasonable after a Type A or B aortic dissection or after prophy-lactic repair of the aortic root/ascending aorta. In studies dedicated to investigating the natural history of thoracic aortic aneurysms, patients with a chronic type B aortic dissection tended to have more aortic complications when the aortic diameter reached 5.5 to 6 cm. aortic dissection is a type of acute aortic syndrome(AAS) characterised by blood entering the medial layer of the wall with the creation of a false lumen. AAS is a spectrum of life-threatening thoracic aortic pathologies including intramural hematoma, penetrating atherosclerotic ulcer, and aortic Thoracic aortic dissection: pitfalls and artifacts in MR imaging.

Acute type B aortic dissection (ATBAD) (identified within 2 weeks of symptom onset), as described using the Stanford classification, accounts for 25-40 of all aortic dissections. Stanford type B or DeBakey III aortic dissection originates in the descending thoracic aorta without retrograde Complicated Stanford type B (DeBakey type III) aortic dissections with specific clinical or radiologic evidence.Modern techniques of diagnosing and repairing thoracic aortic dissections transformed the condition from a death sentence to a treatable disorder—as shown by the experience of Dr Furthermore, anterior chest pain is often associated with type A AAD while type B sometimes shows back or abdominal pain . We found that this is true in this case. Since 1999, when Dake et al.  first applied endovascular stent-graft to repair acute thoracic aortic dissection (TEVAR) successfully, it thoracic aorta (Type B PAU). Less frequently, PAUs are located in. the aortic arch or abdominal aorta, while involvement of the ascend-ing aorta is rare.245,251,256,257224.

The aim of this retrospective study was to evaluate aortic volume changes in patients with acute type B aortic dissection (TBD), treated either by thoracic endovascular aortic repair (TEVAR) or conservatively. Objectives This study sought to evaluate the early and long-term effect of thoracic endovascular aortic repair (TEVAR) on type-B acute aortic dissection (AAD).
