Danish experience with the one-piece shunt. A long-term follow-up.

A review of the efficacy and complications of the simple one-piece ventriculoperitoneal shunt is given, based on a consecutive series of 61 children with nontumorous hydrocephalus. Control of the hydrocephalic state was satisfactory but was, however, complicated by a rather high frequency of slit ventricles and subdural effusions. No significant increase in the complication rate was observed among premature babies. The infection rate was low (3%) and no visceral perforations were observed. The one-piece shunt can be recommended, especially for smaller children with hydrocephalus.

A cohort study of neural tube defects (NTD) in Denmark covering the first seven years of life.

In the County of Fyn, Denmark, which is a well-delimited region comprising a 10% representative sample of the total population, ten complete one year cohorts of newborn were scrutinized for neural tube defects (NTD). Among 66,000 births, 71 cases with NTD were observed. The total prevalence at birth was 1.08/1,000; 0.29 for anencephaly; 0.20 for encephalocele, and 0.59 for spina bifida (SB). This is at the same level as in other Scandinavian countries. Considering only neonates born alive, 57% of the total survived until the age of 7 years, disregarding anencephaly, but only 4 of 18 SB cases and 6 of 11 encephalocele cases had no handicaps at age 7. On the average, SB patients spent 9% of their life before the age of 7 years in hospitals and encephaloceles 2%. The SB cases occupied 25 times more beds per year than the comparable age group in general and many were likely to need continued medical and social care.

Clinical features and outcome in 1076 patients with ruptured intracranial saccular aneurysms: a prospective consecutive study.

In a well-defined area, The Kingdom of Denmark, 1076 patients with ruptured intracranial aneurysms were admitted to the six Danish neurosurgical departments in a prospective consecutive study in the 5-year period 1978-1983. Follow-up examinations were accomplished 3 months and 2 years after the admission. A total of 674 women and 402 men with a median age of 49 years were included in the study. The localisation of the ruptured aneurysms were: internal carotid artery 285, anterior communicating artery and horizontal part of anterior cerebral artery 383, middle cerebral artery 291, basilar and vertebral arteries 83 and peripheral or other localisation 34. A significantly better outcome was seen in cases with internal carotid aneurysms compared to other localisations. 670 patients underwent operation. A highly significantly better outcome was found in operated versus non-operated patients in comparable clinical conditions. The advantage of microneurosurgery was well documented. Patients with vasospasm had a significantly worse outcome. Within the first 2 weeks a daily rebleeding rate from 0.2% to 2.1% was observed, and patients who rebled had a significantly worse outcome compared to patients, who did not rebleed. The overall outcome at 2-year follow-up was: normal 27.5%, mild dementia 15.8%, severe dementia 9.9%, vegetative 1.3% and mortality 45.5%.

Clinical features and outcome in 48 patients with unruptured intracranial saccular aneurysms: a prospective consecutive study.

During a 5-year period (1978-1983) the clinical features and operative morbidity/mortality were registered prospectively for all patients in Denmark with an unruptured symptomatic (27 patients) or incidental (21 patients) intracranial saccular aneurysm. A follow-up examination was performed 2 years after diagnosis of the aneurysm. Thirty symptomatic aneurysms in 27 patients most frequently involved the visual pathways or ocular motility (66%). The median diagnostic delay for patients with impaired visual acuity was 7 months but only 14 days for patients with impaired ocular motility. The localisation of the 30 symptomatic and 23 incidental aneurysms were: internal carotid artery (73% approximately 35%), anterior communicating artery (3% approximately 26%) and middle cerebral artery (7% approximately 35%). The diameters of 73% of the symptomatic aneurysms were greater than 10 mm, while the diameter of 74% of the incidental aneurysms were below 10 mm. The total operative morbidity and mortality were 15% and 4%, respectively. The mortality rate in the follow-up period was 10-11% mainly due to fatal bleeding from unoccluded aneurysms. In 21 survivors, a normal mental status was found in 43% and mild dementia was found in another 43%. The impaired visual acuity was unchanged in 67% of patients, while the ocular motility had normalised in 75%. A normal daily functional capacity was enjoyed by 57% while 43% had a moderate reduction, mostly due to visual disturbances.

Growing intracranial arteriovenous malformation in a newborn.

A case is reported of a growing arteriovenous malformation in a newborn, premature baby. The reason for early operative intervention is emphasized, based on histological investigation of the malformation. The literature is reviewed.

Nonsurgical treatment of a traumatic brain abscess in a child.

A large traumatic brain abscess in a 9-year-old white boy was successfully treated conservatively with antibiotics, including metronidazole and ampicillin. No neurological or psychological sequelae, except for unilateral loss of the olfactory sense, were revealed at follow-up 5 years later, and on CT two minor hypodense areas remained in the right frontal lobe. Our treatment protocol includes metronidazole (0.5 g 3 times a day) and ampicillin (1 g 6 times a day) for adults. This seems to be the treatment of choice in cases of intracranial brain abscesses.

Reversible ischemic neurological deficit and minor strokes before and after EC/IC bypass surgery. A neuropsychological study.

Thirty-three patients with reversible ischemic deficits or completed minor strokes had their cerebral function measured neuropsychologically a few days before and 3 months after extra-intra cranial bypass surgery. Three months post-operatively bypass patency was demonstrated by angiography. Ten patients were operated on the right side and 23 on the left side. The right hemisphere patients were found to be neuropsychologically intact or only slightly impaired before, as well as after, the operation whereas the left hemisphere patients pre-operatively had impaired verbal sequential thinking, reduced capacity for repetition, verbal learning, and mental arithmetic. Post-operatively they improved significantly on 5 of 15 tests and performed no worse on any test than the control group. Consequently, they, too, had post operatively no or only slight neuropsychological impairment.
