To investigate the role of digital subtraction angiography (DSA) in evaluation of carotid cavernous fistulas, and to initiate a new classification for carotid cavernous fistula.
Cerebral angiography and selective external and internal carotid angiography were carried out in 56 patients who were classified into 5 types according to their hemodynamic features.
The types were A (38 patients), B (4), C (10), D (2), and E (2). One of the 38 direct fistulas was located at C1 of the cavernous segment. Fistulas at C2 were observed in 10 patients, at C3 in 4, at C4 in 10 and at C5 in 5. The anterior communicating arteries were patent and well compensated in 33 of the 56 patients. The posterior communicating arteries were patent and well compensated in 39 patients. Both communicating arteries were well compensated in 31 patients. Fifty of the 56 patients were drained by ophthalmic veins, 47 by inferior petrous sinuses, 18 by cortical veins, and 8 to the posterior fossa region.
Digital subtraction angiography was helpful in localization of the rents in carotid cavernous fistulas, in evaluation of function of Willis circles and provided valuable information for treatment of carotid cavernous fistulas. Carotid cavernous fistulas were divided into 5 categories: type A, B, C, D and E, among which type E was not previously described elsewhere.
探讨数字减影血管造影（DSA）在评估颈内动脉海绵窦瘘中的作用，并提出颈内动脉海绵窦瘘的新分类。
对56例患者进行脑血管造影及选择性颈外、颈内动脉造影，根据血流动力学特征将其分为5型。
5型分别为A（38例）、B（4例）、C（10例）、D（2例）和E（2例）。38例直接瘘中1例位于海绵窦段C1。10例患者瘘位于C2，4例位于C3，10例位于C4，5例位于C5。56例患者中33例前交通动脉通畅且代偿良好。39例患者后交通动脉通畅且代偿良好。31例患者双侧交通动脉均代偿良好。56例患者中50例经眼静脉引流，47例经岩下窦引流，18例经皮质静脉引流，8例引流至后颅窝区域。
数字减影血管造影有助于定位颈内动脉海绵窦瘘的破口，评估Willis环功能，为颈内动脉海绵窦瘘的治疗提供有价值的信息。颈内动脉海绵窦瘘分为5类：A、B、C、D和E型，其中E型此前未见其他报道。
