Case ReportsThe 'triangle' rubber dam interposition technique: preservation of the arteries around an aneurysm.
The authors describe an intraoperative technique in which a triangular rubber dam is inserted between the aneurysm and the perforating arteries. In this way, we can avoid obstruction of perforating arteries on application of a clip. This technique is especially useful for deep-seated aneurysms, such as basilar bifurcation aneurysms.

Procedural predictors of delayed cerebral infarction after intra-arterial vasodilator infusion for vasospasm following aneurysmal subarachnoid hemorrhage.
The goals of this study were to identify predictors of delayed cerebral infarction in aneurysmal SAH after intra-arterial (IA) vasodilator infusion and to select proper parameters for treatment success. ⋯ Angiographic CCT and residual narrowing at the end of IA vasodilator infusion were found to predict the subsequent occurrence of cerebral infarction. The authors suggest that residual narrowing of 30% and a CCT of 7 s could be used as a minimum indicator of IA vasodilator infusion endpoints.

Comparative StudyThe sutureless excimer laser assisted non-occlusive anastomosis (SELANA); a feasibility study in a pressurized cadaver model.
To compare intracranial feasibility of the conventional Excimer laser assisted non-occlusive anastomosis (ELANA) with the new experimental sutureless ELANA (SELANA). ⋯ This comparative study shows potential advantages of the SELANA anastomosis over the ELANA anastomosis because during application, it causes less manipulation of surrounding structures while it is faster and easier. Further preclinical research should be performed in order to improve SELANA feasibility on angulated anastomosis spots and to assess long-term SELANA patency and endothelialization.

Anti-apoptotic and neuroprotective effects of α-lipoic acid on spinal cord ischemia-reperfusion injury in rabbits.
Radical oxygen species produced after injury counteracts antioxidant activity and frequently causes severe oxidative stress for the tissues. Alpha-lipoic acid is a powerful metabolic antioxidant with immunomodulatory effects which provides neuroprotection. The aim of this study is to investigate the neuroprotective and anti-apoptotic effects of alpha-lipoic acid on spinal cord ischemia-reperfusion. ⋯ Although further studies considering different dose regimens and time intervals are required, the results of the present study prove that alpha-lipoic acid has favorable effects on experimental spinal cord ischemia-reperfusion injury.

Stereotactic radiofrequency amygdalohippocampectomy in the treatment of mesial temporal lobe epilepsy.
Minimally invasive percutaneous single trajectory stereotactic radiofrequency amygdalohippocampectomy was used to treat mesial temporal lobe epilepsy (MTLE). The aim of the study was to evaluate complications and effectiveness of this procedure. ⋯ Stereotactic amygdalohippocampectomy is a minimally invasive procedure with low morbidity and good results that can be the method of choice in selected patients with MTLE.
