Keywords: aortic dissection, endovascular procedures, acute disease, computed tomography angiography, selection for treatment. Aortic dissection - Wikiwand Acute aortic dissection is the most familiar and is defined by a separation of the layers of the aortic wall by an inciting intimal injury. With TTE and TEE, a diagnosis of dissection was confirmed by the presence of two vascular lumens separated by an intimal flap; if there was complete thrombosis of the false lumen, a central displacement of intimal calcifications was considered to be diagnostic of aortic dissection 17-19,23 . The first is standard open-heart surgery. Classification and outcomes of extended arch repair for acute type A aortic dissection: a systematic review and meta-analysis dagger. Dissection of the aorta is characterized by separation of the aortic wall in the outer third of the media thereby creating a false lumen in the aortic wall There are several anatomic classification schemes for describing aortic dissections, but the most widely used is the Stanford nomenclature, which. Patients typically present with sudden onset severe pain radiating into the chest, back, or abdomen. Although pain is the most common presenting symptom in AAD, painless acute aortic dissection may occur in approximately 5% of patients [13, 14].

Aortic Dissection Classification: Stanford (More commonly used) -. Stanford classification Type A (60%): Involves ascending aorta, regardless of site of origin Type B (40%): Does not involve ascending aorta DeBakey classification Type I. Aortic dissection is a surgical cardiac emergency characterized by tears in the innermost layer (tunica intima) of the aorta. Though aortic dissection is most commonly the domain of vascular surgeons and interventional radiologists, it does occasionally involve the arch of the aorta, and the management for both conditions involves the tight control of haemodynamic variables. 3:1 male to female predominance.
