本文对14例脑膜瘤行术前预外动脉栓塞,7例止血效果良好,7例出血仍偏多。影响栓塞止血效果的原因有:(1)术中损伤较大血管;(2)肿瘤有预外和颈内动脉的双重供血;(3)或有双颈外动脉供血;(4)靶血管距颈总动脉近,为避免返流而栓子量注入不足。这几种因素尤其(2)、(3)二项影响栓塞效果较大,但仍起到较大止血作用。并对有关栓塞技术作了介绍。 Preoperative extracorporeal arterial embolism in 14 cases of meningioma in this article, 7 cases of hemostasis with good results, 7 cases of bleeding is still partial. The reasons for the effect of embolization to stop bleeding are: (1) intraoperative injury of larger vessels; (2) the tumor with extra-external carotid artery and internal dual supply of blood; (3) or external carotid artery supply; (4) target vessel distance Common carotid artery, in order to avoid reflux and emboli injection inadequate. These factors in particular (2), (3) two embolization effect larger, but still play a greater role in hemostasis. And introduced the embolization technology.
