Treprostinil use has been reported to result in clearing of gastrointestinal and central nervous system findings as well as clearing of cutaneous lesions, but reports are limited. Treprostinil may be more effective than other vasodilators because it may also increase the population of circulating endothelial cells, allowing angiogenesis. Recent research
A 46-year-old male patient was diagnosed with the malignant, systemic form of the disease and was severely ill. The diagnosing dermatopathologist, Cynthia Magro MD, identified the presence of C5b-9 complexes in the involved vessels of the skin biopsy. For treatment of the thrombotic microangiopathy in this patient, she suggested the use of eculizumab, a humanized monoclonal antibody drug developed by Alexion Pharmaceuticals and approved by the Food and Drug Administration for treatment of Paroxysmal nocturnal hemoglobinuria. The patient experienced a dramatic improvement in his condition. Lee Shapiro MD and Aixa Toledo-Garcia MD at Albany Medical College learned of the success with the adult patient, and became the first physicians to successfully treat a pediatric Degos patient with eculizumab.Dr. Shapiro later observed the resolution of Degos skin lesions in an adult patient with an overlap syndrome involving systemic lupus, systemic sclerosis, and Degos disease who was treated with treprostinil for her pulmonary hypertension. His pediatric Degos patient was developing significant complications despite treatment with eculizumab, so Dr. Shapiros group became the first to treat a Degos patient with treprostinil. To this point, all known long-term survivors of systemic Degos disease are being treated with a combination of eculizumab and treprostinil.
The tapes used to tie against the ring provide a larger contact surface area than the traditional stitches, thus it provides stronger anastomosis and better surgical results.A number of comorbid conditions increase the surgical risk of repair of an aortic dissection. These conditions include the following:
Prolonged preoperative evaluation (increased length of time prior to surgery)
Advanced age
Comorbid disease states (e.g. : coronary artery disease)
Aneurysm leakage
Cardiac tamponade
Shock - obstructive shock
Past history of myocardial infarction
History of kidney failure (either acute or chronic kidney failure)

Follow-up
The long-term follow-up in individuals who survive aortic dissection involves strict blood pressure control. 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 130 mmHg.The risk of death is highest in the first two years after the acute event, and individuals should be followed closely during this time period. About 29% of late deaths following surgery are due to rupture of either a dissecting aneurysm or another aneurysm. In addition, a 17% to 25% incidence exists of new aneurysm formation, typically due to dilatation of the residual false lumen. These new aneurysms are more likely to rupture, due to their thinner walls.Serial imaging of the aorta is suggested, with MRI being the preferred imaging technique. Prognosis
Of all people with aortic dissection, 40% die immediately and do not reach a hospital in time. Of the remainder, 1% die every hour, making prompt diagnosis and treatment a priority.
