药物成份或治疗方案详述: |
一 OOT 1.主支与边支预处理:确定主支与边支,分别下钢丝,并酌情行球囊预扩张或其它预处理。 2.球囊-支架有序依偎扩张术(balloon-stent sequentially snuggling dilation, BSSSD):定位主支支架,预埋边支球囊、其近端标记略高于血管嵴;首先扩张边支球囊、再扩张主支支架,随后减压主支支架球囊、再减压边支球囊。BSSSD可防止血管嵴/斑块移位,使钢丝可从覆盖边支开口最远测的支架网孔再次进入边支,此为OOT的关键步骤和先决条件。预埋球囊可防止边支闭塞。 3.近端优化(proximal optimization technique, POT):选择较主支血管大(1:1.25)、而短的NC球囊(<8mm),远端标记略高于血管嵴水平,缓慢加压扩张使主支支架自血管嵴水平以上逐步扩大,同时可使覆盖边支开口的支架网孔扩张、网格呈现斜坡状。POT可酌情使用,BSSSD与POT结合可使钢丝更容易从覆盖边支开口的最远测网孔再次进入边支。 4.边支再过钢丝、撤出边支内预埋的球囊和钢丝:若无POT,则在BSSD后边支再过钢丝。经BSSSD和/或POT后,第三根钢丝很容易从覆盖边支开口最远测的支架网孔再次进入边支。通常在此时将预埋于边支内的球囊和钢丝撤出,也可在BSSSD后或POT后将其撤出。 5.序贯球囊对吻扩张技术(sequential kissing balloon dilation, SKBD):选择两大小合适的非顺应球囊(边支1:0.8,主支1:1.25),近端标记对齐于嵴水平略上,首先扩张边支并维持扩张压力、接着扩张主支形成序贯球囊对吻扩张态势,如此可使覆盖边支开口的冗余支托外翻并覆盖边支开口上缘,即获得理想的边支开口优化效果。 6.再次最终近端优化(re-POT):以首次POT使用的NC球囊,远端标记略高于血管嵴水平,逐步后撤扩张使主支近端支架全部充分扩张贴壁。 二 POT及其衍生技术 1.主支与边支预处理:确定主支与边支,分别下钢丝,并酌情行球囊预扩张或其它预处理。 2.主支支架植入:按主支近、远端参考血管直径的均值,选择尺寸合适的支架并植入。 3.近端优化(proximal optimization technique, POT):选择较主支血管大(1:1.25)、而短的NC球囊(<8mm),远端标记略高于血管嵴水平,缓慢加压扩张使主支支架自血管嵴水平以上逐步扩大,同时可使覆盖边支开口的支架网孔扩张、网格呈现斜坡状。 4.边支再过钢丝、撤出边支内保护钢丝:经POT后,第三根钢丝较容易从覆盖边支开口最远测的支架网孔再次进入边支;但若血管嵴/斑块移位,则钢丝难以最远测的支架网孔再次进入边支。随后,将预埋于边支内的保护钢丝撤出。 5.POT-side-POT或POT-kissing-POT:选择两大小合适的非顺应球囊(边支1:0.8,主支1:1.25),边支球囊跨越开口、主支近端标记对齐于嵴水平略上,首先扩张边支(side)、随后扩张主支(POT),与首次POT组合完成POT-side-POT操作;或者,边支与主支球囊近端标记对齐于分叉核心区(POC),同步对吻扩张,随后略回撤主支球囊再次行POT,与首次POT组合完成POT-kissing-POT操作。 6.再次最终近端优化(re-POT):以首次POT使用的NC球囊,远端标记略高于血管嵴水平,逐步后撤扩张使主支近端支架全部充分扩张贴壁。 |

Description for medicine or protocol of treatment in detail: |
The procedural steps of OOT were described as follows: 1) MB and SB pretreating: wiring the MB and SB, pre-dilating of them as indicated. 2) Balloon-stent sequentially snuggling dilation (BSSSD): delivering the stent to MB; pre-embedding the balloon in SB and keeping its proximal marker line up with carina; inflating the SB balloon, then releasing and expanding the MB stent; finally deflating the MB stent balloon, then the SB balloon. 3)Proximal optimization technique (POT): Select a larger (1:1.25), shorter NC balloon (<8mm) than the main vessel stenting, and the distal marker is slightly higher than the carina, slowly dilating so that main vessel stent is gradually enlarged from the level of carina, and at the same time, the struts cells the MB stent facing the SB ostium is expanded and sloped. The POT can be used as appropriate, and the combination of BSSSD and POT makes it easier for rewiring the SB through the most distal cell of the MB stent facing the SB ostium. 4) Rewiring and withdraw the pre-embedded balloon and wire in the SB: If there is no POT, then the rewiring will be performed after the BSSD. After BSSSD and/or POT, the third wire can easily rewire the SB from the most distal cell of the MB stent facing the SB ostium. The balloon and wire pre-embedded in the side branch are usually withdrawn at this time, and can also be withdrawn after BSSSD or after POT. 5) Sequential kissing balloon dilation (SKBD): select two NC-balloons of equal size (SB: 1:0.8, MB 1:1.25), and the proximal marker of SB NC-balloon is aligned to the carina. The SB balloon is dilated at low-pressure (6-8atm) first; the main vessel balloon is then dilated at a pressure of 8-10atm with little proximal overlap. 6) Re-POT: repeat POT to optimize the morphology of distal PMV and decrease the rate of malapposition. The procedural steps of PORT (POT and its related techniques) was described as follows: 1) MB and SB pretreating: wiring the MB and SB, pre-dilating of them as indicated. 2) MB stenting: selecting suitable stent according to average diameter of the proximal and distal reference vessel, and then stenting the MB. 3) Proximal optimization technique (POT): Select a larger (1:1.25), shorter NC balloon (<8mm) than the main vessel stenting, and the distal marker is slightly higher than the carina, slowly dilating so that main vessel stent is gradually enlarged from the level of carina, and at the same time, the struts cells the MB stent facing the SB ostium is expanded and sloped. 4) Rewiring and withdraw the pre-embedded balloon and wire in the SB: after the POT, the third wire is easier to enter the side branch again from the most distal cell of the MB stent facing the SB ostium; however, if the carina/plaque shift occurs after main vessel stent implantation, it is difficult to rewire SB from the most distal cell of the MB stent facing the SB ostium. Subsequently, the protective wire pre-embedded in the SB is withdrawn. 5) POT-side-POT or POT-kissing-POT: Select two non-compliant balloons of appropriate size (SB: 1:0.8, main branch 1:1.25), inflate SB balloon first then peform POT again to finish the POT-side-POT procedure; or both the proximal marker of SB and MB NC-balloon are aligned to the POC segement and inflated concurrently, then peform POT again to finish the POT-kissing-POT procedure. 6) Re-POT: repeat POT to optimize the morphology of distal PMV and decrease the rate of malapposition. |
