Cerebral arterial vasospasm is the major complication of subarachnoid haemorrhage. This process of unclear aetiology causes significant increases in the morbidity and mortality of patients with subarachnoid haemorrhage. In this study all physiopathological characteristics of subarachnoid haemorrhage...

Recent studies suggest that Nimodipine. a potent calcium-channel antagonist that causes significant cerebrovascular dilatation, may improve neurological outcome after acute experimental permanent focal cerebral ischaemia in animals when given before or immediately after occlusion of the middle cereb...

Cortical sensory potentials were evoked intraoperatively under general anaesthesia by median nerve stimulation in 13 out of 14 patients with frontoparietal tumour. In 13 patients, the central sulcus could be identified by phasereversal of cortical somatosensory evoked potential (CSEP) across the cen...

The authors study the effectiveness and complications of intraventricular morhphine therapy in the treatment of preterminal cancer pain and compare it with other central and systematic administarions of morphine. In this series of 35 patients, intraventricular morphine therapy was used when complic...

Two cases of vertebral arteriovenous fistula (VAF) one caused by an angiographic catheter during coronary angiography and other due to a gunshot wound are presented. Preoperative and postoperative angiographic verification of the lesions was demonstrated. Both patients were treated by direct surgica...

The case of a 33-year-old man with a hemangioma involving the frontal sinus is reported. The patient presented with a gradually increasing hard lump over the forehead and frontal headaches. Characteristic changes on plain X-ray and computed tomography supported this diagnosis. The lesion was removed...

Benign solitary schwannomas arise often from cranial nerves, but they may be located at any part of the body, especially in the face and neck region. A 17-year old woman was accepted in our clinic for an extracranially growing tumour at the occipito-cervical region. She had been operated twice in an...

A case of migration of a Pudenz type peritoneal shunt catheter into the abdominal wall diagnosed with computed tomography is presented. This is a rare complication of ventriculoperitoneal shunt. It seems that a foreign body in the abdominal cavity and infection are the most important causal factors.

The properties of tumours of the jugular foramen are presented and the details of the infratemporal A approach, a new technique for neurosurgeons are discussed.

A case of mucocele of the sphenoid sinus that presented with sellar and parasellar extension is reported. This rare entity should be considered in the differential diagnosis of lesions causing destruction of the sellar floor even if there is lack of historical or radiographic evidence of primary par...
