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. Other tests that may be used include an aortogram or magnetic resonance angiogram of the aorta.

Arteriovenous fistula Arteriovenous malformation Telangiectasia Hereditary hemorrhagic telangiectasia. Type A aortic dissection [21]. Disdccion thought to be the diagnostic gold standardit has been supplanted by other, less-invasive imaging modalities. Among the recognized risk factors for aortic dissection, hypertension, abnormally high levels of lipids such as cholesterol in the bloodand smoking tobacco are considered preventable risk factors.

Aortcia is a relatively noninvasive test, requiring the individual to swallow the echocardiography probe. An aortic dissection secondary to an intramural hematoma should be treated the same as one caused by an intimal tear.

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 disecciln October ; the report describes dissection of the aortic arch and into the pericardium.

SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal’s impact. People with an aortic dissection often have a history of high blood pressure ; the blood pressure is quite variable at presentation with acute aortic dissection, and tends to be higher in individuals with a distal dissection.

The mean age at diagnosis is 63 years. Due to the high-intensity magnetic fields used during MRI, it is contraindicated in individuals with metallic implants. It is a noninvasive test, does not require the use of iodinated contrast material, and can detect and quantitate the degree of aortic insufficiency. A TEE may be technically difficult to perform in individuals with esophageal strictures or varices.

From Monday to Friday from 9 a. Aortic dissection affects an estimated aaortica.

Indications for the surgical treatment of aortic dissection include an acute proximal aortic dissection and an acute distal aortic dissection with one or more complications.

DeBakeyis an anatomical description of the aortic dissection. For uncomplicated Stanford type B distal aortic dissections including disecxion aortic dissectionsmedical management is preferred over surgical.

Si continua navegando, consideramos que acepta su uso. Another mechanism is that the dissection may extend into the aortic root and detach the aortic valve leaflets. The proximity of the aorta to the esophagus allows the use of higher-frequency ultrasound for better anatomical images.

The high pressure rips the tissue of the media apart along the laminated plane aotica the inner two-thirds and the outer one-third of the media apart. Disadvantages of TEE include the inability to visualize the distal ascending aorta the beginning of the aortic archand the descending abdominal aorta that lies below the stomach. Aortic dissection may be a late sequela of heart surgery.

An acute dissection is one in which the individual presents within the first two weeks. Through these secondary tears, the blood can re-enter the true lumen. 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.

This page was last edited on 1 Decemberat Thoracic Aortic Disease Coalition. The blood travels through the media, dideccion a false lumen the true lumen is the normal conduit of blood in the aorta. Since no direct connection exists between the true lumen and the false lumen in these cases, diagnosing an aortic dissection by aortography is difficult if the cause is an intramural hematoma.

These individuals are prone to dissection in the ascending aorta. The long-term follow-up in individuals who survive aortic dissection involves strict blood pressure control.
