Despite encouraging results from screening trials the efficacy of mammography in reducing mortality remains somewhat controversial. Five studies have been done in Sweden. This overview, based on 282,777 women followed for 5-13 years in randomised trials in Malmö, Kopparberg, Ostergötland, Stockholm, and Gothenburg, reveals a 24% (95% confidence interval(More)
In a series of 715 patients operated on by microsurgical techniques for intracranial saccular aneurysms between 1970 and 1980, part of the aneurysmal sac was not obliterated in 28 aneurysms in 27 patients (3.8% of 715 cases). Clinical follow-up evaluation for 8 years (range 4 to 13 years) and angiographic follow-up studies for 6 years (range 2 to 10 years)(More)
OBJECTIVE To investigate whether angiograms obtained 2 years after radiosurgery, proving total arteriovenous malformation (AVM) occlusion, represent the final state of treated AVMs and adjacent normal vessels. METHODS Angiograms were obtained for 48 patients 5 to 24 years after gamma knife radiosurgery and 4 to 17 years after the AVMs had been proven to(More)
The authors report outcomes in 18 patients with arteriovenous malformations (AVMs) who were treated with gamma knife radiosurgery and in whom magnetic resonance (MR) imaging was obtained a mean of 14 years (range 8-23 years) after treatment and 10 years (range 4-17 years) after confirmed obliteration of the AVM. All patients were asymptomatic after(More)
A study of 6 selected arteriovenous malformation (AVM) patients was performed to investigate the feasibility of delineating an AVM on MR images and to compare the AVM volume outlined on different images. Conventional stereotaxic angiograms, stereotaxic MR images and MR angiograms using several different pulse sequences were obtained prior to radiosurgery.(More)
OBJECTIVE To study the results after fractionated radiotherapy of large arteriovenous malformations (AVMs). METHODS Twenty-eight patients harboring large AVMs were treated between 1980 and 1985 with fractionated radiotherapy with up to 3.5 Gy per fraction twice a week to a total dose of 41 to 50 Gy. All but 5 patients were examined with an angiogram at(More)
CT scans have been made on 39 of 41 patients who presented with subarachnoid hemorrhage. Blood could be visualized in the cisterns of 18 of 32 examinations performed within five days of the hemorrhage all having aneurysms. Among the other 14 there were three in whom no aneurysm was found on angiography. The distribution of blood in those that showed it was(More)
A case with an ill-defined arteriovenous malformation in the parieto-occipital region is presented. Open surgery was unsuccessful in removing the AVM totally, and treatment with gamma knife radiosurgery was then attempted. At 14 months after this treatment the AVM was believed to be obliterated. The patient had a new intracranial haemorrhage 59 months after(More)
The reports of rupture of an aneurysm during carotid angiography are very few but the actual incidence is doubtless higher than recorded. The case presented is documented with the demonstration of a large middle cerebral artery aneurysm with an intratemporal hematoma, and, in sequence, the rupture of the aneurysm during the height of the injection and the(More)
Optic neuritis (ON) is a common first manifestation of multiple sclerosis (MS), and examination of patients with ON provides opportunities to study the early clinical stages of MS. This prospective study compares results of brain magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) examinations and HLA-Dw2 phenotyping in 60 consecutive patients with(More)
