CTA in patients with acute subarachnoid haemorrhage. A comparative study with selective, digital angiography and blinded, independent review.

Purpose: Minimal- or non-invasive methods replacing intra-arterial digital subtraction angiography (IA-DSA) would be of great importance in patients suffering from acute subarachnoid haemorrhage (SAH). The aims of this study were to compare CTA with IA-DSA in patients with acute SAH, to compare CTA interpretations with those of blinded, independent reviewers and to evaluate improvement in CTA diagnostics after 1 year of experience with CTA.

Material And Method: During 2 years 162 patients with SAH underwent CTA as well as IA-DSA.

[Leakage of cerebrospinal fluid. Diagnosis and treatment].

Leakage of cerebrospinal fluid may occur after fracture of the skull base or after surgery on the skull base, nose, or paranasal sinuses. Further causes of cerebrospinal fluid leakage are tumours and malformations. It may also occur spontaneously.

[Minor head injuries. May early CT-scanning replace in-hospital observation?].

A one-year prospective study was undertaken to judge whether in-hospital observation after minor head injury could be partly replaced by early computerized tomography (CT), and if such a practice would save hospital resources. All 146 patients had a Glasgow Coma Score (GCS) > or = 14 and no neurological deficits. 128 had suffered loss of consciousness.

Modified Robinson-Smith procedure for the treatment of cervical radiculopathy.

In the present study, a modified Robinson-Smith procedure was used surgery for cervical radiculopathy in 52 patients. Thirty-one one-level and 21 two-level operations were performed. All patients were followed up between 1 and 3 years (mean 23 months) after surgery with a clinical evaluation by an independent investigator including a radiological examination.

Large peripheral cystic schwannomas. Two case reports and a review.

Two patients presented with benign cystic schwannomas, which originated from the brachial plexus and the sciatic nerve, respectively. The tumours were single, egg-shaped growths that were excised completely without damage to the nerve. Histopathological examination confirmed the diagnosis of encapsulated, cystic, benign schwannomas.
