Carotid cavernous fistulas (CCFs) represent uncommon and anomalous communications between the carotid artery and the cavernous sinus. Case report We present the clinical details and successful management of a previously healthy 44-year-old patient who presented with one-month worsening headache, bilateral abducens palsy and conjunctival injection. Imaging modalities including magnetic resonance imaging (MRI) with contrast and digital subtraction angiography (DSA) facilitated the diagnosis of CCF. The patient underwent endovascular coiling of the CCF, leading to neurological recovery and symptom remission. This case highlights the importance of promptly CCF diagnosis in patients with multiple cranial nerve palsies and conjunctival hyperemia. Moreover, it emphasizes the efficacy of endovascular coiling in achieving symptom remission.

颈动脉海绵窦瘘：双侧外展肌麻痹和结膜充血的潜在可治疗原因

颈动脉海绵窦瘘（CCF）代表颈动脉和海绵窦之间不常见且异常的交通。病例报告 我们介绍了一名既往健康的 44 岁患者的临床细节和成功治疗，该患者出现一个月内头痛加剧、双侧外展肌麻痹和结膜充血。包括增强磁共振成像 (MRI) 和数字减影血管造影 (DSA) 在内的影像学检查有助于 CCF 的诊断。患者接受了 CCF 血管内弹簧圈栓塞，导致神经功能恢复和症状缓解。该病例凸显了对多发性颅神经麻痹和结膜充血患者及时诊断 CCF 的重要性。此外，它强调了血管内弹簧圈栓塞在缓解症状方面的功效。
