染料注射MC双胎盘血管的映射是评估复杂，临床治疗的情况下，为进一步加强我们的了解MC的孪生的宝贵的过程。与产科队伍，以确保迅速获得一个完整的胎盘标本的协调是至关重要的。干燥或组织的长期存储在注射之前，可能会导致血管损伤和染料外渗。必须避免胎盘固定，因为交联的血块会阻塞血管染料灌注。在此过程中的关键和困难的一步是脐动脉和静脉插管。这些船只，特别是动脉，是脆...

guide wire assisted catheterization and colored dye injection for vascular mapping of monochorionic twin placentas

单绒毛膜双胎妊娠（MC）的是与显着较高的发病率和死亡率比dichorionic双胞胎。大约50％的MC双胎妊娠并发症所产生的共享胎盘及相关血管连接1。严重的双对双胞胎综合征（TTTS）报道，占约20％，这些并发症 2,3 。双胞胎间的血管连接出现在几乎所有的MC胎盘，都涉及到这些高风险的双胎妊娠的预后和结果。 TTTS和其他的MC双条件的发展有牵连的数量，规模和类型的连接。三种类型的双胞胎间的血管连接出现：1）动脉，静脉连接（AVS），其中一个分支动脉在进行无氧血液从胎盘和潜水成胎盘子叶的胎儿面沿双课程。血液流动通过深部脑实质成出现在胎盘的胎儿面，并带来对其他双含氧血的引流静脉的毛细血管网。是从双单向流，提供对接收传出静脉双的入球小动脉; 2）动脉动脉连接（AAS），其中从每双支动脉符合上肤浅胎盘的表面直接导致血管搏动性双向流，3）静脉静脉连接（VVS），在从每双分支静脉符合直接允许低压双向流动的表面上肤浅的胎盘在产科超声检查宫内有针对性的多普勒审讯已被用来识别存在的AV机管局连接4。产前检测产后胎盘注射液的研究已证实的氨基酸都被证明是改善预后相关的两个双胞胎 5 。此外，双胞胎间的血管连接共享胎盘的胎儿面fetoscopic激光烧蚀现在是年初，严重TTTS的首选治疗方法。 产后胎盘注射液的研究提供了有价值的方法，以确认产前多普勒超声检查结果的准确性和胎儿激光治疗的疗效6。单独使用彩色染料手工注入动脉和静脉循环，每双的技术亮点和描绘AVS，AAS，VVS。这个MC的胎盘血管解剖明确的示范，届时可能与多普勒超声检查和新生儿的结果，以提高我们的MC的孪生及其后遗症的病理生理的认识。在这里，我们展示我们的胎盘注射技术。
