Clip aneurysm is a high incidence disease for people with high blood pressure and arteriosclerosis, and clip aneurysm is a kind of extremely dangerous disease, the danger of causing sudden death is far more than that of any tumors, therefore, we should know about clip aneurysm related knowledge. According to experts, sudden chest pain, abdominal pain or early symptoms of coarctation aneurysm, if symptoms should be operated immediately. The number of aortic coarctation in China reaches at least 50,000 cases every year. Aortic coarctation is often acute, fast-developing and dangerous. Relevant data show that 21% of patients die before reaching the hospital, 50% die in 24 hours, and 68% die in 1 week, which seriously jeopardizes the health of the people in China. Hypertension and atherosclerosis is the main cause of laminated aneurysm The etiology of laminated aneurysm is very complex, common causes are hypertension, atherosclerosis, connective tissue hereditary disease, pregnancy, severe trauma, Marfan’s syndrome and so on, of which, hypertension and atherosclerosis are most common. According to statistics, 80%~90% of patients with entrapment aneurysm are combined with hypertension, and usually have 10~15 years of history of hypertension at the time of onset. The main reason is that high blood pressure will promote the degenerative changes of the aorta in middle-aged and old people, thus reducing the adhesion between the layers of the arterial wall, causing and accelerating the formation of the coarctation aneurysm; and severe atherosclerosis will also exacerbate the degeneration and destruction of the aorta’s mid-membrane, stimulating the growth of the aneurysm. Clip aneurysm four omens need to be vigilant 1, sudden chest pain: clinically, 90% of the patients’ first symptom for the sudden onset of persistent, progressive aggravation of severe chest pain, the pain often occurs when doing some sudden actions, such as lifting heavy objects, playing basketball and abnormal agitation, and even yawning, coughing, straining to defecate and other actions can be triggered, due to the stabbing, tearing or cutting pain, the patient is often The patient often can’t bear it, sweating profusely, with a sense of dying, or even fainting because of the pain. Gastrointestinal symptoms: if the entrapment affects the distal aorta, the patient may have abdominal pain, vomiting, vomiting blood and blood in stool. 3, shock: the patient’s face is pale, sweat, nervousness or fainting, the ends of the limbs are wet and cold, but the blood pressure can be maintained in the hypertensive range or slightly decreased. 4.Psycho-neurological symptoms: if the hematoma involves the carotid artery or the opening of the unnamed artery, it may manifest as transient cerebral ischemia or even stroke. Treatment of aortic coarctation aneurysm The past treatment of aortic coarctation is mainly traditional surgery, traumatic, mortality rate as high as 15% to 26%, paraplegia rate of 25%, and advanced age, combined with important organ insufficiency patients can not tolerate, many patients can only be taken to the conservative treatment, the mid-range and long-term results are poor. From the 1990s to the present, it is another golden period for the vigorous development of aortic coarctation surgery. The development of aortic endoluminal grafts and aortic endoluminal treatment technology has brought aortic coarctation surgery into a new minimally invasive era. Endoluminal therapy is a new method of aortic coarctation treatment, with the outstanding advantages of small trauma, which can reduce the mortality rate to 5% and the paraplegia rate to 0.8%, and thus it is fast becoming the main development trend of aortic coarctation treatment. However, as a new method, its long-term results, especially the potential serious complications, have been a hot topic of academic concern. Endoluminal Isolation A coarctation aneurysm is not a tumor, so its treatment is aimed at preventing rupture without removing the diseased vessel. The “endoluminal” aspect of endoluminal isolation means that the procedure is done in the lumen of the artery, which does not require an open chest, but only an intervention, in which an aneurysm of the aortic coarctation is visualized on an endoluminal angiogram (arrows), and a catheter with an artificial blood vessel of the appropriate size is introduced from the femoral artery, and after reaching the diseased part of the aorta the artificial blood vessel is released from the catheter and an artificial blood vessel with a nickel-titanium alloy stent is attached to the catheter. The artificial blood vessel with a nickel-titanium alloy stent will automatically open up, firmly fixed to the inner wall of the aorta, and completely close the fissure. The artificial blood vessel is like a solid shield, blocking the high-speed and high-pressure blood flow, and eliminating the risk of rupture of the aneurysm. This is also known as “isolation”. The “static” blood remaining in the false lumen will gradually become thrombosed and will eventually turn into a scar.
