Background technology

Bifurcated lesions are relatively common in clinical practice.Have part " false " bifurcated lesions (main branch vessel has Serious Stenosis, Branch vessel does not have obvious stenosis) in carrying out interventional therapy, due to the displacement of speckle, also become " true property " bifurcated lesions (main all has obvious stenosis with branch vessel).Interventional therapy for bifurcated lesions improves short-term effect, but long-term effect Still undesirable.Bracket for eluting medicament can significantly reduce PTCA or and STENTS vascular restenosiss.But for bifurcated lesions, main again Stenosis rate is decreased obviously, but the restenosiss that prop up of side and thrombosis problem still do not solve.The intervention of different types of bifurcated lesions is controlled The selection treating strategy is most important, judges including pathological changes, technical tactic, selection of apparatus etc..For coronary artery bifurcated Pathological changes, always Cardiac interventional doctor facing challenges.

Bifurcated lesions are aided the border areas according to the characteristic distributions of speckle and master the situation of branch vessel angulation, clinically have various typings, Including Lefevre typing, Duke typing, Satian typing, Sanborn typing, Medina typing etc..Various typings all have spy Point, exists again and intersects.In simple terms, from the angular relationship of main branch vessel and side branch vessel, it is divided into Y type pathological changes and T-shaped pathological changes.Right In Y type pathological changes, enter side Zhi Rongyi, but speckle easily shift, though sometimes side branch vessel there is no pathological changes it is also desirable to seal wire or Sacculus is protected.For T-shaped pathological changes, speckle is not easy to shift, but seal wire is not easily accessed side and props up.No matter which kind of type pathological changes, just Often the physical aspect at bifurcated mouth edge is not absolute T-shaped, but is Y type, that is, from main branch vessel carry certain radian to Side branch vessel transition, in bell mouth shape.

At present for the therapeutic strategy of bifurcated lesions, for the branch vessel of side, it is divided into and does not need seal wire to protect, need Want seal wire to protect, and need balloon expandable.The expansion of sacculus is propped up on the protection of seal wire and side, is provided to prevent treated at main Side is occurred to prop up obturation in journey.The branch vessel when the predilation propping up sacculus is conducive to subsequent seal wire to pass through main support mesh to enter, Carry out last kiss is expanded.In conjunction with the interventional therapy of main branch vessel, in simple terms, single-side stand and double bracket two species can be divided into Type.

The support for bifurcated lesions common at present is inserted technology and is included T-shaped support technology and (classical T support technology, changes Good T support technology, necessity T support technology etc.), crush technology (include improvement crush technology, substep crush technology, Reverse crush technology, inverted crush technology etc.), Y type support technology, synchronization is to kiss support technology, trousers skirt (Culotte) support technology, and (the Interventional cardiology second edition, the long-living chief editor of horse, the 37th chapter such as DK-crush technology P494-516, inverted crush stenting such as Figure 22).

From the point of view of current various art formulas, there are some clearly disadvantageous parts.Except relative complex, such as seal wire of performing the operation It is not easy to be passed into side branch vessel from a main support mesh, sacculus passes through or expansion web is at the moment likely to rupture etc., other Also have：First, possible during seal wire pumpback damage side branch ostium or stent migration；2nd, side is propped up seal wire and is entered from main support mesh Or a main seal wire passes through from the mesh of side support, all it cannot be guaranteed that seal wire in well under lumen of vessels axis, with During balloon expandable afterwards, blood vessel wall stress has probabilistic impact；3rd, there is unnecessary one layer at the branch ostium of side Or double layer of metal net, some main support two ends may have three-layer metal net, increased the chance of restenosiss；4th, such as side support Prominent main is more, and sacculus is longer in main part, during main balloon expandable while support to while prop up internal migration, increase to tube wall Damage, easily cause the tear of inner membrance.5th, excessive to two sacculus parallel portion during kiss expansion, it is likely to result in sharp at opening Space at angle is elongated, overextending at obtuse angle；6th, conventional balloon expansion and support release are not accomplished at opposite side branch ostium Physical aspect on arc-shaped transition area good fit, be also that one of the reason restenosiss and thrombosis is propped up on postoperative easy formation side； 7th, uncertainty of shape after the main Zhi Shuanchong sacculus extruding when vascular bifurcation is in main in support etc..These problems Main cause be probably operator be confined to current apparatus, lack to the amount meeting physical aspect at bifurcated vessels opening Body support customized and sacculus, and there is no the balloon-stent induction system being suitable for.
