Injection of acrylic material into the aneurysm is a relatively simple procedure if escape of the material into the circulation can be prevented by means of a coil inserted into the aneurysm prior to injection of the acrylic material. In the present study, polypropylene (00000) suture was given a coiling property. On extrusion through a 22 gauge spinal needle the suture regained its coiled shape. Experiments were carried out on dogs with the external carotid artery serving as a model for an aneurysm. Using a 22 gauge spinal needle, first the coiled suture was inserted into the aneurysm and then methylmethacrylate was injected. Ten aneurysms were thrombosed. None of the animals suffered a neurological deficit. Complete thrombosis of the aneurysms were noted in all the animals. On perfection, this technique could eventually be used for stereotaxic thrombosis of intracranial aneurysms.
如果在注入丙烯酸材料之前通过插入动脉瘤内的线圈防止材料逸入循环系统，那么将丙烯酸材料注入动脉瘤是一个相对简单的过程。在本研究中，聚丙烯（00000）缝线具有了盘绕特性。通过22号脊椎穿刺针挤出时，缝线恢复其盘绕形状。以犬的颈外动脉作为动脉瘤模型进行实验。使用22号脊椎穿刺针，首先将盘绕的缝线插入动脉瘤，然后注入甲基丙烯酸甲酯。十个动脉瘤形成血栓。没有一只动物出现神经功能缺损。在所有动物中均观察到动脉瘤完全形成血栓。完善后，该技术最终可用于颅内动脉瘤的立体定向血栓形成。
