DISECCION AORTICA PDF

En la clasificación de Dubost, la disección abdominal representa del 1 al 2% de todas las disecciones aórticas, cuadro clínico aún más infrecuente si excluimos. El presente documento pretende ser una guía para la orientación diagnóstica y el tratamiento médico inicial de la disección aórtica aguda, proximal o distal. RESUMEN. Introducción: La disección aórtica es una enfermedad de pronóstico muy reservado, con una elevada mortalidad, aun cuando se diagnostique.

Dissection of the descending part of the aorta 3which starts from the left subclavian artery and extends to the abdominal aorta 4. Long-term blood pressure control is required for every person who has experienced aortic dissection. Connective tissue disorders such as Marfan syndromeEhlers-Danlos syndromeand Loeys—Dietz syndrome increase the risk of aortic dissection.

The earliest fully documented case of aortic dissection is attributed to Frank Nicholls in his autopsy report of King George II of Great Britainwho had been found dead on 25 October ; the report describes dissection of the aortic arch and into the pericardium. An MRI examination of the aorta produces a three-dimensional reconstruction of the aorta, allowing the physician to determine the location of the intimal tear and the involvement of branch vessels, and to locate any secondary tears.

Aortic dissection

Retrieved from ” https: Cherry hemangioma Halo nevus Spider angioma. It is usually associated with pericardial tamponade, severe aortic insufficiency, or rupture of the aorta.

Rupture leads to hemorrhaging into a body cavity, and prognosis depends on the area of diseccion. Individuals with Marfan syndrome tend to have aneurysms aortca the aorta and airtica more aortida to proximal dissections of the aorta. Anterior chest pain is associated with dissections involving the ascending aorta, while interscapular back pain is associated with descending aortic dissections. Vasodilators such as sodium nitroprusside can be considered for people with ongoing high blood pressure, but they should never be used alone, as they often stimulate a reflexive increase in the heart rate.

Philosophical Transactions of the Royal Society. In this subset, the incidence in young individuals is increased. Aortic dissection is more common in those with a history of high blood pressurea number of connective tissue diseases that affect blood vessel wall strength such as Marfan syndrome and Ehlers Danlos syndromea bicuspid aortic valveand previous heart surgery.

Disadvantages include the need for iodinated contrast material and the inability to diagnose the site of the intimal tear.

Anterograde dissections may propagate all the way to the iliac dideccion of the aorta, rupture the aortic wall, or recanalize into the intravascular lumen leading to a double-barrel aorta. The intensity loudness of the murmur depends on the blood pressure and may be inaudible in the event of low blood pressure.

The Stanford classification is divided into two groups, A and B, depending on whether the ascending aorta is involved. The DeBakey system, named after cardiothoracic surgeon Michael E.

Classically, new widening of the mediastinum on radiograph is of moderate sensitivity for detecting an ascending aortic dissection; however, this finding is of low specificityas many other conditions can cause apparent widening of the mediastinum. From Monday to Friday from 9 a. Views Read Edit View history.

The disadvantage of the MRI scan in the face of aortic dissection is that it has limited availability and is often located only in larger hospitals, and the scan is relatively time-consuming, which may be dangerous in people who are already very unwell.

SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal’s impact. Beta blockers are the first-line treatment for patients with acute and chronic aortic dissection.

Aortic dissection – Wikipedia

Surgery for aortic dissection was first introduced and developed by Michael E. Common tests used to diagnose an aortic dissection include a CT scan of the chest with iodinated contrast material and a transesophageal echocardiogram. Vascular surgerycardiothoracic surgery. SRJ is a prestige metric based on the idea that not all citations are the same. Archived from the original on 5 January The right coronary artery is involved more commonly than the left coronary artery.

Previous article Next article. Archived from the original on 24 December As with all other arteries, the aorta is made up of three layers, the intimathe mediaand the adventitia. The ascending aorta 1 and aortic arch 2 are not involved in this image. Continuing navigation will be considered as acceptance of this use.

aotrica Chest trauma leading to aortic dissection can be divided into two groups based on cause: The Stanford classification is useful as it follows clinical practice, as type A ascending aortic dissections generally require primary surgical treatment, whereas type B dissections generally are treated medically as initial treatment with surgery reserved for any complications.

Concern should be increased in those with low blood pressure, neurological problems, and an unequal pulses.

Depends on the type [1]. The risk of dissection in aottica with bicuspid aortic valve is not associated with the degree of stenosis of the valve.

Acute infrarenal abdominal aortic dissection. Syphilis only potentially causes aortic dissection in its tertiary stage. DeBakey developed aortic dissection himself at age 97 in[3] and underwent surgery in CiteScore measures average citations received per document published.
