在栓塞剂凝集前选择性导管的位置对于得到最好的治疗效果和最少的并发病是重要的。然而有时由于血管弯曲和/或病变范围较大,则选择性插管是不可能的。此时血流控制硅胶液的栓塞术是有价值的。本文介绍栓子递送系统是改进的双腔导管,有两个方面与常规的双腔导管不同:①同胶囊球(Balloon)相连的导管腔伴同其导管壁的横断面
The location of the selective catheter before the embolic agent is agglutinated is important for the best therapeutic effect and minimal concurrent disease. Sometimes, however, selective intubation is not possible due to the wide range of vessel curvatures and / or lesions. At this point the blood flow control of silicone embolization is valuable. This article describes an embolic delivery system that is an improved dual-lumen catheter that differs from a conventional dual-lumen catheter in two ways: ① The catheter lumen connected to the balloon is associated with the cross-section of its catheter wall
