RESUMO
Developmental venous anomalies (DVAs) are cited as the most common intracranial vascular anomaly. In the majority of cases, it has a benign clinical course, and complications such as intracranial hemorrhage (ICH) are rarely reported. In the rare cases of DVAs presenting ICH, the causes of hemorrhage are usually by a combined vascular anomaly, mostly cavernous malformation (CM) or complicated DVAs, such as thrombosis in the vein of DVAs. We report a rare case of uncomplicated DVA presenting hemorrhage without accompanied vascular anomaly, such as CM. The cause of hemorrhage is suggested to be a specific form of DVA, arterialized DVA. Arterialized DVAs should be noted that they have a greater risk of hemorrhage than classic DVAs.

RESUMO
We report a case of the transradial approach for carotid artery stenting (CAS) as a useful alternative to the traditional transfemoral approach when femoral access is not available. A 50-year-old male visited our emergency room with dysarthria and right-side weakness. Magnetic resonance imaging showed acute cerebral infarction on the left middle cerebral artery territory and carotid stenosis on both sides. CAS for each carotid stenosis was attempted by the usual femoral access, but there was no pulse on either side of the femoral artery, and computed tomography angiogram of the lower extremity revealed Leriche syndrome, which is an aortoiliac occlusive disease. So, we changed the access to the radial artery and was successfully performed.

RESUMO
Traumatic optic neuropathy (TON) is an important cause of severe visual loss after blunt or penetrating head and facial trauma. High-dose steroids and surgical interventions have been applied in the indirect TON. However, there is no convincing evidence that results of the treatment have any strong benefits in terms of improvement of visual acuity. Nevertheless, surgical decompression should be considered in the case of a direct bony compression to the optic nerve and a progressive visual loss in indirect TON. Neurosurgeon should be aware the surgical indication, optimal timing and relevant technique for the optic canal (OC) decompression. In this review article, we will focus on the surgical approaches to the OC and how to decompress it.
