The aim of the study was to evaluate the effectiveness and reliability of a combined computed tomography angiography (CTA) and computed tomography perfusion (CTP) approach in the diagnosis of cerebral vasospasm after subarachnoid hemorrhage. ⋯ Combined one-shot CT angiography and CT perfusion represents a valid alternative to DSA in the diagnosis and management of cerebral vasospasm.

Since the first landmark randomized trials on unruptured bAVMs were published, there has been emerging concerns about the role of endovascular therapy. For bAVMs considered inoperable, embolization remains an option worth considering, especially in young patients presenting with a rupture. We aimed to review the curative potential of contemporary stand-alone embolization techniques enabling high occlusion rates and their respective short and long term safety profile. ⋯ Stand-alone curative embolization, as well as exclusive microsurgery or radiosurgery each play complementary roles. Hemorrhagic, deep-seated lesions are an interesting subtype of surgically unfavorable bAVMs that may benefit from exclusive transvenous embolization, when carefully selected. Larger randomized trials and prospective registries are needed to establish the place of stand-alone or neoadjuvant endovascular treatment.

Perioperative seizure prophylaxis with antiepileptic drugs (AED) has been advocated in patients undergoing supratentorial craniotomy. The practice remains controversial. The reasoning presupposes that the possibility of an adverse drug reaction from the AED is lower than the probability of harm from a seizure. Even short periods of hypotension during the operation can lead to acute kidney and myocardial injury. We retrospectively evaluated cardiovascular effects and tolerability of levetiracetam (LEV) alone, LEV and lacosamid (LCM) as compared to phenytoin (PHT). ⋯ LEV alone and in combination with LCM for patients without and with symptomatic epilepsy as seizure prophylaxis provides a safe and feasible alternative to PHT. PHT was associated with an unfavorable drop in blood pressure during anesthesia and more adverse reactions.
