Hemorrhage rates of external ventricular drain (EVD), intracranial pressure gauge (ICP) or combined EVD and ICP gauge placement within 48 h of endovascular coil embolization of cerebral aneurysms.
In single patients with a cerebral aneurysm an external ventricular drain (EVD), an intracranial pressure (ICP) gauge or a combined EVD and ICP gauge placement is necessary after coil embolization and initiation of postprocedural anticoagulation. The aim of this study was to examine the hemorrhage rates of drain placement within 48 h after aneurysm coiling and under anticoagulation or antiplatelet therapy. ⋯ EVD, ICP gauge or combined EVD and ICP gauge placements within 48 h after cerebral aneurysm coiling and under different anticoagulation or antiplatelet regimens seem to have no increased risk of hemorrhages compared to literature.

Case ReportsImage guidance to improve reliability and data integrity of transcranial Doppler sonography.
Principles and accuracy of image-guided transcranial Doppler (IG TCD) sonography have been published recently. However, it remains open whether combination of image guidance and TCD offers an additional clinical advantage. This study scores the accuracy of conventional TCD examinations and investigates the potential improvement of TCD data integrity and reliability regarding the additional use of IG. ⋯ Our data suggest, that misinterpretation of the vascular source of the Doppler signal is a common source of errors in conventional TCD. Visualization of the vascular anatomy by image guidance offers improved accuracy and reliability of TCD results and may positively influence the learning curve for inexperienced investigators.

Early superficial temporal artery to middle cerebral artery bypass in acute ischemic stroke.
To evaluate the effects and safety of superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis in the early stage after an acute ischemic event and the improvement of present symptoms in patients with intracranial atherosclerotic occlusive disease with stroke/stroke in progress. ⋯ In this study, which consisted of 20 carefully selected patients with acute ischemic stroke, an early STA-MCA bypass was safely and effectively performed, and in some cases, an early STA-MCA bypass resulted in rapid neurological improvement. An early STA-MCA bypass was beneficial in select patients who had acute ischemic stroke with imaging evidence of a small infarction.

Adolescent lumbar disc herniation: experience from a large minimally invasive treatment centre for lumbar degenerative disease in Chongqing, China.
This article discusses the aetiology, medical history, physical examination, imaging characteristics and treatment modalities relevant to this entity aiming to increase awareness among paediatricians regarding LDH (lumbar disc herniation) in young children. ⋯ Diagnosis of LDH in young children is usually delayed, but there were no risk factors for the delayed outpatient diagnosis of LDH. Awareness of LDH will help the paediatrician extract a relevant medical history, perform a directed physical examination and order appropriate imaging studies.

Case ReportsMedial posterior choroidal artery territory infarction associated with tumor removal in the pineal/tectum/thalamus region through the occipital transtentorial approach.
Damage to the deep venous system, occipital lobe, and/or corpus callosum is well known to cause complications associated with the occipital transtentorial approach (OTA), but ischemic complications are not well documented. The authors investigated the high incidences of ischemic complications associated with removal of pineal/tectal/thalamic tumors through the OTA. ⋯ A relatively high incidence of MPChA territory infarction was associated with removal of tumors in the pineal/tectal/thalamic region through the OTA. Eye symptoms often occurred post-surgery and tended to persist in these patients. Neurosurgeons must be aware of the possibility of MPChA territory infarction to further increase the safety of the OTA.
