It is especially good in the evaluation of AI in the setting of ascending aortic dissection and to determine whether the ostia (origins) of the coronary arteries are involved. While many institutions give sedation during transesophageal echocardiography for added patient comfort, it can be performed in cooperative individuals without the use of sedation. Disadvantages of TEE include the inability to visualize the distal ascending aorta (the beginning of the aortic arch), and the descending abdominal aorta that lies below the stomach. A TEE may be technically difficult to perform in individuals with esophageal strictures or varices. Aortogram
An aortogram involves the placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta. The procedure is known as aortography. Previously thought to be the diagnostic gold standard, it has been supplanted by other, less-invasive imaging modalities. Classification
Several different classification systems have been used to describe aortic dissections. One such classification is based on chronicity and labels aortic dissections as hyperacute (<24 hours duration), acute (2–7 days), subacute (8–30 days), and chronic (>30 days). The systems commonly in use are based on either the anatomy of the dissection or the duration of onset of symptoms before the presentation. The Stanford system is used more commonly now, as it is more attuned to the management of the patient. DeBakey
The DeBakey system, named after cardiothoracic surgeon Michael E. DeBakey, is an anatomical description of the aortic dissection.
Travoprost, sold under the brand name Travatan among others, is a medication used to treat high pressure inside the eye including glaucoma. Specifically it is used for open angle glaucoma when other agents are not sufficient. It is used as an eye drop. Effects generally occur within two hours.Common side effects include red eyes, blurry vision, eye pain, dry eyes, and change in color of the eyes. Other significant side effects may include cataracts. Use during pregnancy or breastfeeding is generally not recommended. It is a prostaglandin analog and works by increasing the outflow of aqueous fluid from the eyes.Travoprost was approved for medical use in the United States and in the European Union in 2001. It is available as a generic medication in the United Kingdom. In 2017, it was the 212th most commonly prescribed medication in the United States, with more than two million prescriptions. Medical uses
Travoprost is used to treat high pressure inside the eye including glaucoma. Specifically it is used for open angle glaucoma when other agents are not sufficient. Side effects
Possible side effects are:
blurred vision
eyelid redness
permanent darkening of eyelashes
eye discomfort
permanent darkening of the iris to brown (heterochromia)
burning sensation during use
thickening of the eyelashes
inflammation of the prostate gland, restricting urine flow (BPH)Research suggests that wiping the eye with an absorbent pad after the administration of eye drops can result in shorter eyelashes and a lesser chance of hyperpigmentation in the eyelid, compared to not wiping off excess fluid.
