Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of aorta tectorial membrane stent.
Background technology
Arotic disease (dissection of aorta, aortic aneurysm) is one of complicated, the most dangerous cardiovascular disease, its sickness rate is annual 50-100 people/100,000 crowds, and Aortic Dissection 65%��75% patient dies from the complication such as aorta rupture, periphery internal organs hypoperfusion, cardiac tamponade, apoplexy in acute stage (in 2 weeks). In the Chinese 2/3 patients with aortic dissection aneurysm cause of disease for not control hypertension, according to National survey in 2002, estimate that there is a hyperpietic 1.6 hundred million in the whole nation, but control rate only 6%, therefore dissection of aorta also exists disease basis widely. Along with the improvement to the understanding of this disease and inspection apparatus, its discovery rate was obvious ascendant trend in recent years, had become commonly encountered diseases at big cardiovascular diseases center. And diameter has 10% to break more than 5.0 breasts, abdominal aortic aneurysm every year, along with the increase of diameter, the risk broken is bigger, the aortic aneurysm broken to death in hospital rate also up to 50%. Arotic disease has had a strong impact on the healthy of the people, becomes great public health problem, and the treatment tool of this type of disease is of great significance.
In the recent decade, aorta tectorial membrane stent endovascular graft has been widely used for dropping, the pathological changes such as aneurysm and artery dissection of ventral aorta, and has been obtained for good brachymedial phase effect. Its determined curative effect, wound are little, recovery is fast, few intercurrent disease, it has also become first-line treatment. For aortic arch pathological changes, because relating to the big important arterial branch of brachiocephalic trunk, left common carotid artery and left subclavian artery three, often it is difficult to obtain support in blood-vessel and implants required enough anchorage zones, be considered as previously " the operation forbidden zone " of intracavity stent implantation. Growth along with the progress of Endovascular and patient's experience, at present aortic arch pathological changes is had been developed in " the hybridization operation " that intracavity technology combined with surgical operation, and other EVARs, such as technology etc. such as branching type Stent, chimney Stent, windowing stent implantations. But easily there is internal hemorrhage due to trauma, complicated operation, wound is big, easily cover bow top set, causes severe complication. Similarly, for ventral aorta involve branch vessel pathological changes also be difficult to intracavity overlay film frame as conventional therapy, although there being the technology such as windowing stent, chimney, periscope at present, but complicated operation, need customization, late result imprecise.At present without simple, easy, the safe Perfected process processing aortic arch and ventral aorta branch vessel pathological changes, the pathological changes at this position is the difficult point of intracavitary therapy all the time, limits intracavity minimally-invasive treatment widely using in this type of disease.
Orthotopic fenestration (insitufenestration) is when not windowing in advance, relocate the opening of target artery after traditional overlay film frame graft is planted human aorta, and windowed by lancet puncture or laser boring, balloon expandable overlay film frame at branch vessel place. 2004, McWilliams etc. first applied this kind of support and has successfully repaired aneurysm of thoracic aorta. Recent Bj rnSonesson etc. break patient close to brachiocephalic trunk place aortic arch one, and pre-leading stock carotid artery by-pass ensures cerebral circulation, and row the method is windowed brachiocephalic trunk and the total Stent Implantation of left neck afterwards. The patient that anchorage zone is little, Conventional coverlay film support need to cover branch vessel should be applicable in this way, simple, accurate positioning. But maximum shortcoming is overlay film frame first covers branch vessel, windows afterwards, windows and require time for, easily causes branch vessel severe ischemic. For ensureing cerebral circulation, needing pre-leading stock carotid artery by-pass in advance to ensure cerebral circulation, its difficulty is big, and clinic is difficult to extensively carry out; It is likely to stent graft is caused tearing of " uncontrollable " when being additionally and puncture and cut overlay film fabric. Only having Short-term observation at present, its curative effect still needs to further look at, and the complexity of operation and the risk of cerebral infarction will exponentially increase. Lack the overlay film frame being suitable for windowing at present.
The material main material of current overlay film frame has terylene (PET), expanded PTFE (ePTFE) etc., it has enough tensile strengths, the impact of high pressure blood flow can be resisted, have good biocompatibility, stent thrombosis will not be caused. Fabric permeability and porosity is low make support insert after closure former cut of interlayer, effectively stop the blood flow traffic in the true and false chamber of aorta, true chamber expands, and false chamber thrombosis or false chamber disappear. But overlay film frame difficulty is windowed at present, needs special device. Window again after covering branch vessel, take time, target blood ischemia can be caused. Windowing after maybe needing to bend upper bypass, clinical procedure is complicated and is difficult to promote again. It is used for left subclavian artery at present to rebuild, and left neck is total, brachiocephalic trunk is likely to result in serious consequence because of ischemia.
Complete intracavitary therapy Development of Universal, applicable and the graft that bow can be protected again to go up incidence and ventral aorta branch vessel blood flow, be current focus and difficult point to reach the complete intracavity minimally-invasive treatment of complex lesions.
