Direct carotid-cavernous fistula (CCF) by selective navigation using a microcatheter or microwire is a rare complication, and its timing of treatment has not been elucidated. We report two cases of direct CCFs resulting from injury to the cavernous posterior segment of the internal carotid artery during selective navigation. We did not plan to perform emergent endovascular treatment for these direct CCFs because no symptoms related to direct CCFs developed. Follow-up angiography revealed spontaneous healing of both direct CCFs. Close observation rather than emergent treatment may represent another option for direct CCF by selective navigation during the endovascular procedure.
Case Details
Disease Location
Brain
Personal Characteristics
70 years old woman . No medical history and no neurologic deficit.
Clinical Characteristics
Severe headache. Subarachnoid hemorrhage in the basal cistern but no definite aneurysm sac. Right hemiparesis.
Remission Characteristics
(1) the patient recovered from right hemiparesis with a new moderate degree of headache. One week after procedure, complete obliteration of the fistula was reached.
Treatment & Mechanisms
Proposed Remission Mechanisms
Iodinate contrast media may promote clot formation in the focal injured vessel wall.
Clinical Treatment
(1) carotid artery stenting.
