Abstract
Local anesthetic systemic toxicity is a rare but serious consequence that occurs when a local anesthetic is introduced into the plasma leading to neurological or cardiac toxic complications. Rich vasculature such as the internal carotid artery, which is adjacent to the interscalene block site, allows hazards to direct unintentional intravascular injections or indirect fast absorption to the regional vascular system. We present an interesting case of a patient who?after interscalene brachial plexus block using bupivacaine?presented with localized ipsilateral cortical hypoxic injury by vasoconstriction of a distal arteriole of the middle cerebral artery which resulted in postoperative focal seizure and severe hemiplegia.
