Background technology
Cardiovascular disease is the first killer threatening compatriots' health at present, and aortic aneurysm is one of the most dangerous anxious, serious symptom cardiovascular disease.Clinically image be called " time bomb ".True property aortic aneurysm, false aortic aneurysm and dissecting aneurysm can be divided into by structure aortic aneurysm.According to pressing happening part, aortic aneurysm can be divided into Ascending Aortic Aneurysm, Aortic arch aneurysm, descending aortic aneurysm or aneurysm of thoracic aorta (starting point is at the far-end of left subclavian artery) and abdominal aortic aneurysm.Dissection of aorta (aorticdissection, AD) refers to that aorta lumen inner blood enters aortic tunica media from aortic tunica intima tear place, makes middle membrance separation, and along the expansion of aorta long axis direction, forms the interlayer of aorta wall.Aortic aneurysm is that the aorta wall middle level caused due to a variety of causes such as atherosclerosis, Intraarterial pressure rising, wounds is impaired, elastorrhexis replaces fibrous scar tissue, namely arterial wall follows the string, blood flow can not be tolerated impact and cause aorta wall local or diffuse abnormal dilatation, compressing peripheral organs and cause the disease of symptom.Along with the arrival of China's aging society, the sickness rate of the chronic disease such as hypertension, atherosclerosis presents obvious increase trend, and one of consequence at a specified future date of these diseases is exactly cause Secondary cases dissection of aorta or aortic aneurysm pathological changes.Recall rate and the sickness rate of dissection of aorta (AorticDissection, AoD) and aortic aneurysm constantly rise.2 ~ 4,/10 ten thousand people are about according to conservative estimation dissection of aorta annual morbidity, dissection of aorta is one of the most dangerous anxious, serious symptom cardiovascular disease, especially involve the dissection of aorta of ascending aorta and aortic arch and the aneurysm patient dissection of aorta that can happen suddenly to break sudden death, the state of an illness is dangerous, very big to human life health threat, Aortic Dissection 24 hours Natural progression only 40%, after 1 week, Natural progression is 25%, its dangerous degree, far away higher than cerebral infarction, heart infarction and malignant tumor, has become the important medical treatment and the social problem that obviously affect compatriots' health.
At present, treat aortic disease and comprise the methods such as Drug therapy, surgical operation therapy, interventional therapy.Drug treatment is mainly by strictly controlling the incidence rate that blood pressure reduces aneurysm continuation expansion or breaks.Surgical operation therapy aspect is aneurysm excision and artificial or vascular homograft mainly, and the operative mortality of current abdominal aortic aneurysm is lower than 5%, but the age is excessive, and intentionally, brain, kidney or other visceral lesion person, surgical death can more than 25%.The operative mortality of aneurysm of thoracic aorta is 30%, maximum with the surgical risk of Aortic arch aneurysm.But operation is carried out under deep hypothermia cardiopulmonary bypass, and there is the risk of spinal cord, brain and important organ ischemic necrosis, a lot of gerontal patient cannot tolerate and holds surgical operation therapy under breast owing to there is high risk factor and lose therapy apparatus meeting.
Along with progress and the extensive use of intervention material; intracavity recovery technique is used for clinical by Parodi first time in 1991; its ultimate principle is: will be covered with the compressible stent of artificial vascular membrane; discharge after they being transported to vascular lesion position by induction system; utilize the memory characteristic of support self; after Endovascular expansion; diseased region (cut as aneurysm or interlayer) is isolated from outside lumen of vessels; blood is passed through in support; thus protect weakness or alleviate the tension force of lesion vessels wall, reach the object of repairing lesion vessels.Endovascular completely cuts off treatment technology and rises thereupon, present technique has become the main method that initiatively interlayer, descending aortic aneurysm or aneurysm of thoracic aorta, abdominal aortic aneurysm fall in treatment, and the early metaphase result of the clinical experimental study of trunk intracavity technology is satisfactory.
At present for the treatment of the aneurysm or artery dissection that are positioned at ascending aorta and aortic arch, be subject to the restriction of intervention material, can not the interior reparation of an actor's rendering of an operatic tune completely.Most employing is entirely bent replacement or is adopted open chest surgery treatment to implant with type great vessel strut the hybridization surgical technic combined.Although the latter, compared with the former, simplifies aortic arch surgery, reduce operating time, reduce postoperative complication.But still can not be completely free of traditional operation as dependence, greatly limit extensively carrying out of aortic arch disease surgery, only just can complete at the department of cardiac surgery center that minority is large, even need hybridization operating room.Especially older, complication person is many, and this modus operandi risk of the patient of body constitution difference is still larger.This just treats aneurysm or the artery dissection of ascending aorta and aortic arch in the urgent need to a kind of stent, make to perform the operation completely to reach Wicresoft completely, safely, be convenient to carry out.
Also research center is had to be devoted to the research of ascending aorta and bow portion support in blood-vessel in recent years, but support Design is too simple, coarse mostly, to aspect shortcomings such as ascending aorta and bow portion hemodynamics, anatomy, biomechanicss, or support Design is too complicated, complex operation step is not easily grasped, be not suitable for clinical practice, fail to solve blood vessel-support consistency problem.In a word, at present become the important study hotspot of of vascular surgery field about bow portion support in blood-vessel, but owing to there is the practical problems such as releasing mechanism complexity, induction system sheath pipe diameter is excessive, branch stent not easily compresses, do not make substantial breakthroughs all the time.
