Transient Cortical Blindness after Digital Subtraction Angiography of Cerebral Vessels

Received, 9 July, 2017 Accepted, 20 July, 2017 Transient blindness following cerebral angiography is a rare but known entity. We report a case of transient cortical blindness after cerebral angiography. The patient presented with ischemic stroke and the angiography was performed to rule out carotid artery stenosis. The patient, however, gradually regained his vision over a period of 3 days. This article is to understand one of the most unusual complications that may occur while performing angiography.

Propofol, An Alternative to Amobarbital in Wadas Test in Electro corticography Based Epilepsy Surgery for Determining Dominance of Brain

Annapurna Neurological Institute and Allied Sciences (ANIAS) has been performing ECOG based epilepsy surgery for many years with good results. The semiology of the patient should be concordant with Electro Encephalography (EEG) reading and Magnetic Resonance Imaging (MRI) fi ndings. Determination of dominant hemisphere in terms of language and memory function is important and is done by the WADA test. This test is usually done by short-acting barbiturate (amobarbital) pushed into an internal carotid artery.2,3,7,10,13,14 However Amobarbital is not available in Nepal, so Propofol an anesthetic agent acting on the central nervous system is used.1,6 Its chemical structure is 2,6 diisopropil fenol, it is insoluble in water and is delivered diluting it with equal proportion with normal saline (10 mg/1 ml of solution).
