Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
Chest trauma leading to aortic dissection can be divided into two groups based on cause: blunt chest trauma (commonly seen in car accidents) and iatrogenic. Iatrogenic causes include trauma during cardiac catheterization or due to an intra-aortic balloon pump. [citation needed] Aortic dissection may be a late sequela of heart surgery. About 18% ...
A study of people who died after traumatic aortic rupture found that in 55–65% of cases the damage was at the aortic isthmus and in 10–14% it was in the ascending aorta or aortic arch. [4] An angiogram will often show an irregular outpouching beyond the takeoff of the left subclavian artery at the aortic isthmus, representing an aortic ...
This may include the neck, left or right arms, cervical spine, back, and upper abdomen. [9] Other associated symptoms with chest pain can include nausea, vomiting, dizziness, shortness of breath, anxiety, and sweating. [8] [1] The type, severity, duration, and associated symptoms of chest pain can help guide diagnosis and further treatment.
Dogs will also pant and rely on the expansion of their blood vessels to regulate their body temperature but none of it is as effective in cooling dogs down as sweating is for humans.
Isolated superior mesenteric artery dissection (ISMAD) is a rare but potentially life-threatening condition that causes acute abdominal pain. It refers to a dissection that occurs solely in the superior mesenteric artery (SMA), typically spontaneously, and does not involve the aorta . [ 1 ]
Due to its low frequency of occurrence, more common causes of hoarseness should be considered when suspecting left recurrent laryngeal nerve palsy (LRLN).. When considering cardiovocal syndrome, the most common historical cause is a dilated left atrium due to mitral stenosis, but other causes, including pulmonary hypertension, [2] thoracic aortic aneurysms, an enlarged pulmonary artery [3] and ...
Canine subvalvular aortic stenosis (SAS) is an abnormal, congenital heart murmur caused by subaortic stenosis (SAS). This genetic trait is polygenic , and in some cases asymptomatic. An animal with SAS may offspring and show no symptoms of the stenosis until multiple generations which is why it is advised not to breed an animal diagnosed with SAS.
