Figure 2.

Digital subtraction angiogram (DSA) of the middle meningeal artery (MMA) in a patient in whom the microcatheter does not reach a stable position in the ostium of the ophthalmic artery (OA). (a) The microcatheter was navigated through the MMA in order to reach the anastomotic ramus (AR) with the supraorbital branch of the OA. (b) The microcatheter is in the AR and after contrast media injection, the OA, its ostium and the internal carotid artery (ICA) fill retrogradely. (c) Late-phase DSA shows both the choroidal and ciliary body blush.
