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 interventional therapy is carried out, due to the displacement of speckle, also become " true property " bifurcated lesions (main has obvious stenosis with branch vessel).For the interventional therapy of bifurcated lesions improves short-term effect, but long-term effect It is 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 and thrombosis problem on side are not still solved.For the intervention of different types of bifurcated lesions is controlled The selection for 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 clinically have various typings according to the situation of the characteristic distributions and main branch vessel angulation of aiding the border areas of speckle, Including Lefevre typings, Duke typings, Satian typings, Sanborn typings, Medina typings etc..Various typings have spy Point, exists again and intersects.In simple terms, from main branch vessel and the angular relationship of side branch vessel, it is divided into Y types pathological changes and T-shaped pathological changes.It is right In Y type pathological changes, easily shift into side Zhi Rongyi, but speckle, even if side branch vessel does not have pathological changes sometimes, it is also desirable to seal wire or Sacculus is protected.For T-shaped pathological changes, speckle is not easy displacement, but seal wire is not easily accessed side.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 types, i.e., from main branch vessel with certain radian to Side branch vessel transition, in bell mouth shape.

At present for the therapeutic strategy of bifurcated lesions, firstly for side branch vessel for, be divided into and do not need seal wire protection, need Want seal wire to protect, and need balloon expandable.The protection of seal wire and the expansion of side sacculus, are provided to prevent to treat at main There is side obturation in journey.The branch vessel when the predilation of a sacculus is conducive to subsequent seal wire to enter through main support mesh, Carry out last to kiss expansion.With reference to the interventional therapy of main branch vessel, in simple terms, two species of single-side stand and double bracket can be divided into Type.

The at present common support for bifurcated lesions inserts technology includes that T-shaped support technology (classical T support technologies, changes Good T support technologies, necessity T support technology etc.), crush technologies (include improvement crush technologies, substep crush technologies, Reverse crush technologies, inverted crush technologies etc.), Y type support technologies are synchronous to kissing support technology, trousers skirt (Culotte) support technology, and DK-crush technologies etc. (《Interventional cardiology》The second edition, the long-living chief editor of horse, the 37th chapter P494-516, inverted crush stenting such as Figure 23).

From the point of view of current various art formulas, there are some clearly disadvantageous parts.It is relative complex except performing the operation, such as lead Silk is not easy to be passed into side branch vessel from a main support mesh, and sacculus is passed through or expansion web is at the moment likely to rupture etc., other Also have：First, possible damage side branch ostium or stent migration during seal wire pumpback；2nd, side seal wire enters from a main support mesh Enter or main seal wire passed through from the mesh of side support, all it cannot be guaranteed that seal wire in well under lumen of vessels axis, During subsequent balloon expandable, blood vessel wall stress has probabilistic impact；3rd, there is unnecessary one at the branch ostium of side Layer 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 Bian Zhizhi Frame project main it is more, sacculus is longer main part, during main balloon expandable while a support to while prop up internal migration, increase to managing The damage of wall, easily causes the tear of inner membrance.5th, it is excessive to two sacculus parallel portions during kiss expansion, it is likely to result at opening Space at acute angle is elongated, overextending at obtuse angle；6th, opposite side branch ostium is not accomplished in conventional balloon expansion and support release The reason for good fit in arc-shaped transition area in the physical aspect at place is also postoperative easy formation side restenosiss and thrombosis it One；7th, main uncertainty of shape in a support when vascular bifurcation is in main after the extruding of Zhi Shuanchong sacculus etc..These are asked The main cause of topic is probably that operator is confined to current apparatus, is lacked to the physical aspect that meets at bifurcated vessels opening The support made to measure and sacculus, and there is no the balloon-stent induction system being adapted to.
