Endovascular treatment of high-flow direct traumatic carotid cavernous fistula (CCF) carries many difficulties. One of them is that carotid dissection may be associated with pseudo-aneurysm formation even when the CCF can be successfully embolized by detachable balloons. This article details a unique technique of treating pseudo-aneurysm by obstructing the lumen with preservation of the parent artery.The case presented here involves a 50-year-old man with a history of severe trauma. The angiography revealed that his bilateral high-flow carotid cavernous fistula was successfully embolized by detachable balloons and control digital subtraction angiography at the end of the procedure demonstrated the fistula closed and the internal carotid artery preserved. But two months later, a pseudo-aneurysm formed in the right internal carotid artery. Under endovascular treatment along with other techniques including coils, stent-assisted and covered stent, the pseudo-aneurysm was excluded with preserved ICA. Two years later, the fistula and pseudo-aneurysm both disappeared quietly without patent foreign body reaction in the parent arterial wall.
