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.

These are more common with a history of Marfan syndrome or Ehlers-Danlos syndrome. The mean age at diagnosis is 63 years. In an acute dissection, treatment choice depends on its location. The objective in the surgical management of aortic dissection is to resect remove the most severely damaged segments of the aorta and to obliterate the entry of blood into the false lumen both at the initial intimal tear and any secondary tears along the vessel.

Long-term blood pressure control is required for every person who has experienced aortic dissection. The Stanford system is used more commonly now, as it is more attuned to the aorttica of the patient. It categorizes the dissection based on where the original intimal tear is located and the extent of the dissection localized to either the ascending aorta or descending aorta or involves both the ascending and descending aorta. 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.
Continuing navigation will be considered as acceptance of this disccion. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal’s impact.
The initiating event in an aortic dissection is a tear in the intimal lining of the aorta. A measurement of blood D-dimer level may be useful in diagnostic evaluation. DeBakeyis an anatomical description of the aortic dissection.
In these cases, the inciting event is thought to be an intramural hematoma caused by bleeding within the media. 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.
It is a relatively noninvasive test, requiring the individual to swallow the echocardiography probe. This item has received. A Systematic Review and Meta-analysis”. Blood pressure control, not smoking . An aortic dissection secondary to an intramural hematoma should be treated the same as one caused by an intimal tear. A number of comorbid conditions increase the surgical risk of repair of an aortic dissection.
Retroperitoneal and pericardial ruptures are both possible. As with all other arteries, the aorta is made up of three layers, the intimathe mediaand the adventitia. The proximity of the aorta to the esophagus allows the use of higher-frequency ultrasound for better anatomical images.
Archived from the original on 24 December It is a noninvasive test, does not require the use of iodinated contrast material, and can detect and quantitate the degree of aortic insufficiency. 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. An acute dissection is one in which the individual presents within the first two weeks.
Previously thought to be the diagnostic gold standardit has been supplanted by other, less-invasive imaging modalities.
Previous article Next article. An aortogram doseccion placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta.
Advanced Emergency Nursing Journal. The risk of death is highest in the first two years after the acute event, and diseccuon should be followed closely during this time period. Dissection of both the thoracic and abdominal aorta . Anterograde dissections may propagate all the way to the iliac bifurcation of the aorta, rupture the aortic wall, or recanalize into the intravascular lumen leading to a double-barrel aorta.

In acute dissection, fast-acting agents which can be given intravenously and have doses that are easier to adjust such as esmololpropranololor labetalol are preferred. Are you a health professional able to prescribe or dispense drugs? Connective tissue disorders such as Marfan syndromeDizeccion syndromeand Loeys—Dietz syndrome increase the risk of aortic dissection.
