| Summary: | Intra-arterial chemotherapy (IAC) is currently, the first-line treatment for retinoblastomas with successful cure rates. In difficult access or unsuccessful catheterization of the ophthalmic artery (OA), the middle meningeal artery is a second alternative followed by the Japanese technique using balloon. Nevertheless, when a well-developed posterior communicating artery is present, a retrograde approach to the OA through this vessel can be performed to deliver the chemotherapeutic drugs. We present a case of an unsuccessful catheterization of the OA through the internal carotid artery due to a challenging configuration of the OA/carotid siphon angle and describe an alternative form of navigation and catheterization through the posterior circulation. To our knowledge, this is the third report of a successful retrograde catheterization of the OA for IAC and constitutes an alternative route to deliver chemotherapy. |
