28例颈动脉海绵窦瘘血管内栓塞治疗的影像学研究

报告２８例各型颈动脉海绵窦瘘血管内行可脱球囊或固体栓子栓塞治疗，其中９例经眼上静脉逆行插管栓塞海绵窦，均获成功。２５例有外伤史，１５例确定瘘口位置。海绵窦瘘分型：Ａ型：２３例；Ｂ型：１例；Ｃ型：２例；Ｄ型：１例；Ａ＋Ｃ型：１例。２５例海绵窦主要通过眼静脉引流，眼上静脉扩张平均值为０．７６ｃｍ，１３例有不同程度“偷流”现象。栓塞后造影，海绵窦和引流静脉消失。作者强调，血管造影是为各型瘘提供手术入路和愈后评价的客观依据，并对眼上静脉入路栓塞治疗的可行性进行了探讨。

Imaging Study of Carotid-Cavernous Fistula Treated with Endovascular Emholization(Analysls of 28 cases)

This article reported the imaging study of 28 cases with carotid cavernous fistula(CCF)treated with detachable balloon or Ivalon. In 9 cases,the superior opthalmic vein approach with retrograde cathetevization was employed successfully. 25 cases had history of previous trauma. In 15 cases,the location of fistula was identified.Classification of CCF was as follows. Type A:23 cases;type B:1 case;type C:2 cases;type D: 1 case and type A C : 1 case.In 25 cases,superior opthalmic vein was the main draining vein,and dilated to an average diameter of 0. 76cm. 13 cases showed signs of steal. Angiography after emboiization showed that cavernous sinus and draining vein had disappeared.The authors emphasized that angiography is essential in providing informations re-gaiding the proper surgical approach for various types of fistula and in therapeutlc evaluation. The feasibility of superior opthalmic vein approach was also discussed.
