[Neurological sequelae of child abuse. Literature review].

Child abuse is both socially and medically troublesome and many times produces permanent consequences. A review of the literature is done from a neurosurgical standpoint, and the lesions produced at the Central Nervous System are evaluated in detail, including their physiopathology, neurological sequels and implications for rehabilitation treatment and the child's future life.

Direct percutaneous carotid artery stenting with distal protection: technical case report.

We describe the technique of percutaneous carotid artery stent placement with distal protection in a patient in whom marked innominate artery ectasia prevented transfemoral access to the right common carotid artery. After induction of general anesthesia, ultrasound was used to guide direct puncture of the common carotid artery followed by the introduction of a 5 French sheath. A GuardWire distal protection balloon (Medtronic, Santa Rosa, CA) was placed distal to the lesion and deployed at nominal diameter.

Basilar artery to bilateral posterior cerebral artery 'Y stenting' for endovascular reconstruction of wide-necked basilar apex aneurysms: report of three cases.

Endovascular reconstruction of basilar artery (BA) apex aneurysms has been augmented by adjunctive techniques such as balloon and stent assistance. We present three cases of a wide-necked BA apex aneurysm involving the bilateral P1 segments of both posterior cerebral arteries (PCAs) treated by placement of BA to PCA stents bilaterally in a 'Y' configuration to reconstruct the BA apex for effective coil embolization. Three patients (aged 70, 65 and 37 years) with wide-necked basilar artery aneurysms presented for endovascular treatment.

Current concepts on the expression of neurotrophins in the greater omentum.

The omentum has been utilized in Neurosurgery since the late 1960s. Its overwhelming effects on fibroblast and peripheral nerve growths were soon noticed. However, there was no direct evidence of production of any of the growth factors by the omentum, although substances were shown to be present in the omentum.
