Delayed ischemic neurologic deficit (DIND) is a serious and poorly understood complication of aneurysmal subarachnoid hemorrhage. Although advances in treatment have improved prognosis for these patients, long-term clinical outcomes remain disappointing. ⋯ Although our understanding of the underlying molecular processes and pathophysiology is improving, responsible mediators or pathways have yet to be identified. The aim of this review is to summarize the key historical events that have helped shape our understanding of the pathophysiology of this phenomenon (microcirculation, autoregulation, microthrombosis, inflammation, apoptosis, spreading depolarization, oxidative stress) and to present the evidence underlying current treatment strategies (hemodynamic therapy, oral nimodipine, endovascular therapy, statins, cerebrospinal fluid drainage, thrombolysis, magnesium) and the translational and clinical research investigating DIND.

Randomized Controlled Trial
Efficacy of low-dose tissue-plasminogen activator intracisternal administration for the prevention of cerebral vasospasm after subarachnoid hemorrhage.
Vasospasm is one of the important factors associated with the functional prognosis after subarachnoid hemorrhage (SAH). Intracisternal administration of thrombolytic agents to dissolve subarachnoid clots may be responsible for bleeding complications. The efficacy and safety of cisternal irrigation therapy using low-dose tissue plasminogen activator were evaluated. ⋯ Cisternal irrigation therapy using low-dose tissue plasminogen activator is effective and safe. Intermittent injection is most effective and may decrease the risk of symptomatic vasospasm in patients with SAH.

Review Case Reports
The role of external drains and peritoneal conduits in the treatment of recurrent chronic subdural hematoma.
A considerable body of evidence supporting the use of external drainage after evacuation of primary chronic subdural hematoma (CSDH) exists in the literature. However, no systematic study of the value of postoperative drainage in the treatment of recurrent CSDH has been published. The aim of the study was to investigate external drains and subdural-to-peritoneal conduit in the treatment of recurrent CSDH. ⋯ The results indicate that, as in the treatment of primary CSDHs, the use of drain (SED or SPC) with burr hole evacuation is safe and is associated with lower recurrence rate. Further investigation is needed to clarify the indications of currently available surgical techniques in the treatment of recurrent CSDH.
