Damage is big, and complication is more, and the death rate is high.And still there are large quantities of patients to be difficult to reality because merging the dysfunction of other vitals
Apply surgical operation therapy.It is put forward for the first time within 1991 abdominal aneurvsm intracavitary repairing and treating (endoluminal aortic
Aneurysm repair, EAAR).In recent years, with the development that guided Interventional Technique and equipment make rapid progress, aortic aneurysm
Endovascular repair (endovascular aneurysm repair, EVAR) gradually move to maturity.Due to conventional surgical hand
The advantages that art is compared, and is had not open chest, is not opened abdomen, and wound is small, and postoperative complication is few, and the hospital stays is short and idicatio is extensive, mesh
Before have become this kind of disease, the especially prefered method of high risk patient's clinical treatment, and actively applied to aneurysm of thoracic aorta and chest
The intracavitary repairing and treating (thoracic endovascular aneurysm repair, TEVAR) of arteries and veins dissecting aneurysm.Although
EVAR has above-mentioned many advantages, and systemic complications incidence is relatively low (accounting for 12%), however, it is in aneurysm of thoracic aorta
It is but subject to certain restrictions in treatment.
Reason one, since aneurysm of thoracic aorta may involve important blood vessels branch (left subclavian artery, Zuo Jing on the arch of aorta
Total artery, right side truncus brachiocephalicus), TEVAR treatments are likely to be faced with since tumor neck is too short or the first break location gets too close to bend
Top set's artery and cause not implementing to block or block incomplete awkward situation, and Stanford A type dissecting aneurysms are even more quilt
It is considered the contraindication of TEVAR.In recent years, after TEVAR coordinates chimney technology (chimney technique) or removes vessel branch
Arch of aorta top set blood vessel bypass transfer operation (debranching method) is used as that the surgery arch of aorta cannot be received
The means of supplementing out economy of such anatomical features aneurysm of thoracic aorta TEVAR operations of displacement.However, chimney technology is inevitably brought
Postoperative interior leakage problem, causes late result bad, and the blood vessel bypass transfer operation of vessel branch arch of aorta top set is gone to increase
The difficulty and wound degree for having added operation, may increase the incidence of cerebrovascular accident.Reason two, since aortic arch has one
Curvature is determined, after film-coated vascular inner rack merging, if anchor region is too short or arch of aorta curvature is excessive, easily big
Curved side and lesser curvature side form leakage in duration.Reason three has the aneurysm neck anchor of similar pathophysiological features to early stage aneurysm
Determine inorganizable healing and straight-cylindrical film-coated vascular inner rack between area's extension of a field, overlay film frame and tumor neck vascular wall
It falls off in stent migration caused by the not conformal performance of the arch of aorta of bending.The incidence of latter two complication, will up to 30%
Lead to this high-new and high price (ten thousand yuan/of 15-20) TEVAR clinical treatments failure, limits clinical application and the hair of TEVAR
Exhibition.
