We report a series of 84 consecutive patients (41 women) with 92 distal anterior cerebral artery aneurysms (DACAA). All aneurysms were saccular. Four different locations of DACAAs were found: proximal, 5 aneurysms; frontobasal, 8; genu corporis callosi, 72; and distal, 7. Sixty-five patients presented with subarachnoid hemorrhage (SAH), the rest were(More)
In a consecutive series of 1150 patients with cerebral aneurysms diagnosed in our department by angiography or autopsy between the years 1977-1990, 1007 patients underwent definitive operative treatment of their aneurysms mainly by early surgery. More than half (55%) were operated on during the first three days after subarachnoid haemorrhage (SAH), and more(More)
Early hydrocephalus is a risk factor of shunt-dependent late hydrocephalus (SDHC). In the CT era 1980-1990 we had 835 consecutive patients operated on because of aneurysm and subarachnoid haemorrhage (SAH); 294 had an early hydrocephalus and 67 finally required a shunt. There were 14 patients with normal early CT and SDHC, in all 81 patients needed a shunt(More)
The prevailing opinion seems to accept that the natural course of lumbar spinal stenosis is one of progressive worsening, and that only surgery can check this development. In fact, the choice of treatment for lumbar spinal stenosis is still an open question. The aim of this study was to compare in the matched-pair format the outcome of surgically and(More)
BACKGROUND Aneurysm of the internal carotid-posterior communicating artery (ICA-PCoA) is the most frequent cause of sudden unilateral oculomotor palsy. Timely surgery for the aneurysm is the most important factor for third nerve recovery. METHODS We scrutinized the world literature with nearly one thousand cases of isolated unilateral oculomotor palsy(More)
To determine the long-term outcome of 12 youthful patients with lumbar disc herniation, who, at the time of surgery, were 15 years old and younger (mean age at operation 14.3 years), we assessed their current clinical condition (mean follow-up time 6 years) with a questionnaire inquiring about symptoms and disability, and radiologically with an MRI of the(More)
It has been widely observed that the outcome after repeat lumbar surgery is rarely comparable to that of primary surgery. In particular, the results of repeat surgery for lumbar spinal stenosis (LSS) have not been favourable. We used a matched-pair format in an attempt to decrease the confounding factors so as to determine as exactly as possible the effect(More)
We studied the metabolic response to acute aneurysm surgery and its modification by parenteral nutrition. Forty-eight patients receiving perioperative corticosteroid treatment were randomly assigned to receive glucose alone (7.2 kcal/day, D5W + C), glucose and a conventional amino acid solution (7.2 kcal/day and 0.15 gN/day, CAA + C) or glucose and branched(More)
