Definition Aortic dissection is a bleeding into the wall of the aorta of the body. In the process, the vessel wall splits into its various layers and blood flows between these individual layers. This creates a new channel next to the aorta through which blood can also flow. Aortic dissection of the Stanford A type … Aortic dissection type A
OP Surgery is an absolute must in type A aortic dissection, as the mortality rate with conservative therapy is 50%. In addition, it is an absolute emergency indication, as the mortality rate increases by 1% with every passing hour. The operation is performed under general anaesthesia. An aortic stent can be inserted to bridge the … OP | Aortic dissection type A
What is an aortic prosthesis? An aortic prosthesis is a vascular prosthesis that is inserted into the aorta. It is an implant that is inserted permanently into the body for therapeutic reasons. It replaces sections of vessels that have been damaged, for example, by aortic dissection, aneurysm or trauma. This repairs the defect and prevents … Aortic prosthesis
What are the risks? In addition to general surgical risks, such as inflammation, wound healing disorders and allergic reactions, there is always the risk of cardiac arrhythmia during surgery near the heart. If the aorta is operated on, there is always a chance of damaging it, which can lead to bleeding. An emergency operation on … What are the risks? | Aortic prosthesis
Definition A complete tear in the wall of the aorta is called an aortic rupture. An aortic rupture is extremely rare and must be surgically treated as soon as possible, otherwise it is absolutely fatal. Even a small tear in the aorta leads to massive bleeding into the body within a very short time. A … Aortic rupture
Associated symptoms The main symptom of an acute aortic rupture is sudden, extreme pain in the chest and upper abdomen. Patients describe the pain as a “stabbing pain of destruction” that can radiate into the back. The tear in the aorta causes massive internal blood loss, which can lead to circulatory instability and even collapse. … Associated symptoms | Aortic rupture
Chances of survival An aortic rupture is a fatal event for the patient and accordingly the chances of survival are very low. The mortality rate (death rate) outside the hospital is 90%. In case of an acute rupture of the aorta, only about 10-15% of patients reach the hospital alive. Despite immediate emergency measures and … Chances of survival | Aortic rupture
Definition The term aortic dissection (Syn. Aneurysma dissecans aortae) describes a splitting (dissection) of the wall layers of the aorta. As a rule, the innermost wall layer (tunica intima) is suddenly torn open, resulting in bleeding between the wall layers (the aorta, like any artery, is made up of the three wall layers tunica intima, … Aortic dissection
Causes of aortic dissection The most important risk factor for aortic dissection is arteriosclerosis, a calcification of the inner vascular layer of the arteries (promoted by increasing age, smoking, diabetes, high blood lipid levels, etc.). A weakness of the tunica media (so-called media degeneration) is also predisposing for a dissection. Here, a dilatation usually occurs … Causes of aortic dissection | Aortic dissection
Symptoms of aortic dissection The so-called leading symptom, which is described by more than 9 out of 10 patients with an acute dissection, is an acute, very severe pain in the chest or abdominal area or in the back. The pain is described by those affected as very intense and stabbing or tearing, sometimes patients … Symptoms of aortic dissection | Aortic dissection
Operation In case of an acute type A dissection, immediate emergency surgery must be performed to prevent a fatal rupture. The patient must be transported to a specialized center for this purpose, as it is a major procedure. The standard procedure during surgery is to replace the ascending aorta with a gore-tex vascular prosthesis. If … Operation | Aortic dissection
Life expectancy in aortic dissection Life expectancy in aortic dissection depends largely on whether type A or B is present, with type B generally having a better prognosis. In addition, life expectancy naturally depends on the patient’s previous illnesses and clinical condition at the time of the acute event. In addition, a ruptured dissection (type … Life expectancy in aortic dissection | Aortic dissection
