Injectable radio-opaque compositions for tissue augmentation and in particular hard tissue augmentation, and kits and methods of using thereof are described herein. The injectable compositions form porous, biologically degradable, fibrin matrices. The compositions are formed from fibrinogen, thrombin or another agent that causes the fibrinogen to crosslink, and strontium salts. Optionally an iodinated contrast agent is further incorporated in the composition. In certain aspects, the compositions have substantially no exothermicity when forming the matrix and the resulting matrices exhibit mechanical properties typically seen in elastomers. Adequate radio-opacity is achieved through the incorporation of strontium salts in combination or not with iodinated contrast agents.
本文描述了用于组织增生的可注射放射不透明组合物,特别是用于硬组织增生的组合物,以及使用它们的套件和方法。可注射的组合物形成多孔、
生物降解的
纤维蛋白基质。这些组合物由
纤维蛋白原、凝血酶或其他导致
纤维蛋白原交联的药剂,以及
锶盐形成。可选择地,在组合物中进一步加入
碘造影剂。在某些方面,这些组合物在形成基质时几乎没有放热性,形成的基质具有通常在弹性体中看到的机械性能。通过将
锶盐与
碘造影剂组合或单独使用,可以实现足够的放射不透明度。
