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.

Archived from the original on The calcium channel blockers typically used are verapamil and diltiazembecause of their combined vasodilator and negative inotropic effects. In the image to the right, color flow during ventricular systole suggests that the upper lumen is the true lumen.
While many institutions give sedation during transesophageal echocardiography for added patient comfort, it can be performed in cooperative individuals without the use of sedation. An aortic dissection secondary to an intramural hematoma should be treated the same as one caused by an intimal tear.
The cause of the infarction is involvement of the coronary arterieswhich supply the heart with oxygenated blood, in the dissection. An echocardiogram displaying the true lumen and false lumen of an aortic dissection: Ritter was initially misdiagnosed and subsequently treated for a heart attack.
The Stanford classification is divided xortica two groups, A and B, depending on disfccion the ascending aorta is involved. Wikimedia Commons has media related to Aortic dissection. Tex Heart Inst J.
Complications include compromise of a vital organ, rupture or impending rupture of the aorta, retrograde dissection into the ascending aorta. Surgery for aortic dissection was first introduced and developed by 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.
Archived from the original on 9 May Thoracic Aortic Aneurysms and Aortic Dissections.

In general, the imaging technique chosen is based on the pretest likelihood of the diagnosis, availability of the testing modality, patient stability, and the sensitivity and specificity of the test. Inflammation Arteritis Aortitis Buerger’s disease.
The scan then follows the contrast as it flows through the vessel. Aortic dissection is associated with hypertension high blood pressure and aorticca connective tissue disorders.

Continuing navigation will be considered as acceptance of this use. The DeBakey aorticaa, named after cardiothoracic surgeon Michael E. This can cause dilatation and weakening of the walls of the ascending aorta. Because of the varying symptoms of aortic dissection, the diagnosis is sometimes difficult to make.
Aortic dissection – Wikipedia
Retroperitoneal and pericardial ruptures are both possible. Retrieved from ” https: It is a relatively noninvasive test, requiring the individual to swallow aogtica echocardiography probe.
Syphilis only potentially causes aortic dissection in its tertiary stage. A TEE may be technically difficult to perform in individuals with esophageal strictures or varices.
Ultrasound of the Ciseccion. 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. Common tests used to diagnose an aortic dissection include a CT scan of the chest with iodinated contrast material and a transesophageal echocardiogram.
The relative risk of late rupture of an aortic aneurysm is 10 times higher in individuals who have uncontrolled hypertension, compared to individuals with a systolic pressure below mmHg. 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 risk of death due to aortic dissection is highest in the first few hours after the dissection begins, and decreases afterward. The particular treatment used depends on the segment or segments of aorta involved. While taking a good history from the individual may be strongly suggestive of an aortic dissection, the diagnosis cannot always be made by history and physical signs alone.
The location of pain is associated with the location of the dissection. While the pain may be confused with the pain of a myocardial infarction heart attackaortic dissection is usually not aodtica with the other signs that suggest myocardial infarction, including heart failure and ECG changes.
