【摘要】 自１９９２年１２月至１９９３年８月，我们采用国产微弹簧圈与其它栓塞材料联合使用，栓塞治疗脑动静脉畸形（ＡＶＭ）５６例。５６例中有７例完全闭塞；栓塞范围占７０％～９５％者３４例，栓塞范围５０％～７０％者１２例，有３例栓塞范围３０％～５０％，占本组病例的５％。这种微弹簧圈的优点是：（１）在荧屏上清晰可见，避免了线段栓塞的盲目性；（２）表面粗糙，易诱发血栓形成；（３）比重大，易停留在ＡＶＭ畸形病灶内，不易被血流冲走；（４）可经各种微导管注射，方法与丝线注射相似，简单可靠、易于掌握；（５）与进口同类产品相比，价格低廉。更多还原

【Abstract】 Abstract From December, 1992 to August, 1993,we embolized 56 cases of cerebral arteriovenous malformations (AVM) using Tungsten micro-coil in combination with other embolizing materials such as Isobuty 1-2-cyanocrylate (IBCA). detachable balloon and silk segments. The advantages of tungsten micro-coil are: (1)easily detected radiographically; (2)its rough surface was easily to promote thrombosis; (3) easily deposited in AVM nidus or feeding artery; (4)easily controlled; (s) to avoid “over embolizing”. The result of 56 cases of AVM embolization. The nidus was completely embolized in 7 cases, 70% ～95% embolized in 34 cases, 50%～70% embolizedin 12 cases. 30%～50% embolized in 3 cases.更多还原
