治疗性栓塞,即有目的栓塞血管性肿瘤和动静脉畸形的血供,作为主要治疗和为减少手术失血的外科辅助性治疗是有价值的。这种技术的并发症多为栓子进入正常组织并引起缺血性梗塞。作者经皮穿刺和透视下将标准的4号、5号或5.8号法国薄壁聚乙烯导管直接插入拟闭塞的动脉。经股动脉或其它动脉进路,用点片、透视或更可取的电子瞬间骨减影技术以确定导管顶端位置。栓塞材料是用纯Conray60制备的混悬液。作者报导39例,其中颅外疾患37例和颅内疾患两例曾用这种技术进行了治疗。有1例发生严重的并发症,但与血流控制栓塞术无关。当非选择性导管操作使栓子不仪闭塞向脑膜瘤供血的脑膜中动脉,同时闭塞了该 Therapeutic embolization, a purposeful embolization of vascular tumors and arteriovenous malformations, is of value as a primary treatment and surgical adjuvant therapy to reduce surgical blood loss. Complications of this technique are mostly emboli into the normal tissue and cause ischemic infarction. The authors inserted standard French thin-walled polyethylene catheters No. 4, No. 5 or No. 5.8 directly into the artery to be occluded percutaneously and fluoroscopically. Via the femoral artery or other arterial approach, spotting, fluoroscopy, or more preferably electronic transient osteoscopy techniques are used to determine the catheter tip position. The embolic material is a suspension prepared with pure Conray60. The authors reported 39 cases, of which 37 cases of extracranial conditions and two cases of intracranial disease have been treated with this technology. One of the patients had serious complications but was not related to blood flow control embolization. When non-selective catheterization of the embolus does not stop occluding the meningioma of the meningeal artery, while blocking the
