OBJECTIVEIntra-ventricular hemorrhage (IVH) is one of the most serious complications of preterm infants. Significant numbers of the surviving infants with severe IVH go on to develop post-hemorrhagic hydrocephalus (PHH). The management of PHH remains a very challenging problem for both neonatologists and pediatric neurosurgeons. This study aimed to evaluate the efficacy and safety of the use of Ommaya reservoirs and serial cerebrospinal fluid (CSF) drainage in the management of a series of neonates with PHH.

METHODBetween January 1, 2003 and December 30, 2005, 15 consecutive newborn infants with IVH grades III to IV, complicated with progressive ventricular dilatation, underwent placement of an Ommaya reservoir. CSF was intermittently aspirated percutaneously from the reservoir. The amount and frequency of CSF aspiration were based on the clinical presentation and the follow-up results of serial cranial ultrasonograms or CT scans. The changes of CSF cell counts and chemistries were also followed. Patients whose progressive ventricular dilatation persisted despite serial CSF aspiration through Ommaya reservoir eventually had ventriculo-peritoneal shunts (V-P shunt) placed. All the patients were followed up in the outpatient clinic after discharge from the hospital and the neurodevelopmental outcomes were evaluated through 18-36 months of age.

RESULTA total of 15 infants were included in this series. Of them, 11 were preterm infants who were at gestational ages of 29 to 34 weeks and 4 infants were full-term. All of the 4 full term infants presented with progressive ventricular dilatation after suffering from the intra-cranial hemorrhage (3 infants were due to vitamin K deficiency and 1 was due to birth trauma). Thirteen infants had grade III IVH, and 2 had grade IV IVH based on initial cranial ultrasonographic and CT scans. The mean age when IVH was diagnosed was (9 +/- 1) days in preterm infants and (22 +/- 7) days in full-term infants; the mean age when Ommaya reservoir was placed was (18 +/- 11) days in preterm infants and (31 +/- 7) days in full-term infants. All the infants tolerated the surgical procedure well. The Ommaya reservoir was tapped for an average of (21.5 +/- 4.6) times per patient. The mean CSF volume per tap was (10.2 +/- 1.3) ml/kg. The values of CSF protein, glucose and cell counts slowly reached normal levels at approximately 3 - 5 weeks after the placement of the reservoir. The velocity of head circumference increase per week was less than 1 cm in 13 patients in 1 - 4 weeks after the placement of the reservoir and the size of ventricles decreased gradually. By 12 - 18 months, 12 infants had normal size ventricles, and 1 patient still had mild ventricular dilation at 36 months. Two infants developed progressive hydrocephalus after serial CSF aspiration through Ommaya reservoir. One infant had a V-P shunt placed at 2 months of age and another infant died at 3 months of age at home after parents refused further therapy. Complications consisted of reservoir leaking and CSF infection at 16th day of placement in one patient after repeated tapping. By the end of 18 - 36 months of follow-up, 11 of 14 infants were considered normal, two patients had mild impairment in neurodevelopmental outcome (both had spastic bilateral lower limbs paresis, and one of whom also had amblyopia) and the other had seizure disorder.

CONCLUSIONThe results from this series indicate that the placement of an Ommaya reservoir is relatively safe in newborn infants and is useful in the initial management of neonates with PHH and may be beneficial in improving their neurodevelopmental outcomes. A multicenter randomized trial may be needed to further validate the results of this report.

OBJECTIVETo investigate the impact of obstructive sleep apnea-hypopnea syndrome (OSAHS) on cerebral microbleeds (CMBs) in patients with cerebral infarction.

METHODSConsecutive patients with acute cerebral infarction who had cerebral microbleeds shown by susceptibility-weighted imaging (SWI) were enrolled to undergo polysomnography (PSG). The patients were divided into two groups, namely non-OSAHS group with apnea-hypopnea index (AHI) less than 5 and OSAHS group with greater AHI, and the clinical and radiological features of cerebral microbleeds were compared between them.

RESULTSForty-nine patients were enrolled in this study, including 27 (55.1%) with both cerebral infarction and OSAHS and 22 (44.9%) with cerebral infarction but not OSAHS. A comparison of the risk factors showed that hypertension, a smoking history, and a history of stroke were more prevalent in patients with OSAHS than in those without OSAHS (P<0.05). The incidences of subclinical stroke in OSAHS and non-OSAHS patients were 37.0% (10/27) and 9.0% (2/22) (P<0.05), respectively. Neurological imaging revealed a greater number of cerebral microbleeds in OSAHS group than in non-OSAHS group (P<0.05). In OSAHS patients, 77.8% of the microbleeds were distributed in cortical-subcortical areas, 55.6% in the basal ganglia area, and 25.9% in the infratentorial area, as compared to the percentages of 50.0%, 40.9% and 50.0% in non-OSAHS patients, respectively (P<0.05). In OSAHS patients, 40.7% also had leukoaraiosis, and 48.1% had two or more causes, as compared to the percentages of 13.6% and 18.2% in non-OSAHS patients, respectively (P<0.05).

CONCLUSIONSOSAHS can be a risk factor for cerebral microbleeds. Patients with both cerebral infarction and OSAHS tend to have greater and more extensive lesions of cerebral microbleeds, more complicated cause of the disease, and a grater likeliness of stroke recurrence.

Although stroke is a great public health challenge in Korea, there have have been few epidemiologic studies of the risk factors stroke. A case-control study was performed to evaluate the risk factors for hemorrhagic stroke in Wonju, Korea. Ninety-five subarachnoid hemorrhage (SAH) and 102 intracerebral hemorrhage (ICH) patients aged 21-86 years, and 267 controls were recruited among the inpatients of Wonju Christian Hospital during 1994-1995. Information was gathered through interview and examinations. After adjustment for age and sex, family and past history of hypertension, drinking habits, age of menarche, height, weight, body mass index, waist and hip circumference, earlobe crease, prothrombin time, white blood cell count, hemoglobin, and total cholesterol were all found to be significantly associated with both SAH and ICH. The risk factor significantly associated only with ICH was smoking habits. In multiple logistics analyses, the independent risk factors for SAH and ICH were the same. Those included family and past history of hypertension, age of menarche, earlobe crease, prothrombin time, white blood cell count, hemoglobin and total cholesterol. In general, the risk factors for SAH and ICH were similar with each other, except smoking habits. Risk factors found in this study congruent with previous studies were family and past history of hypertension, drinking habits, body mass index, prothrombin time, white blood cell count, and hemoglobin. Those incongruent or rather newly found were age of menarche, a big physique, earlobe crease, and total cholesterol.

In recent years, in the absence of venous component, dilated, overlapping, and tortuous arteries forming a mass of arterial loops with a coil-like appearance have been defined as pure arterial malformation (PAM). It is extremely rare, and its etiology and treatment have not yet been fully elucidated. Here, we reported 2 cases of PAM with associated aneurysmal subarachnoid hemorrhage in this paper. Both patients had severe headache as the first symptom. Subarachnoid hemorrhage was found by CT and computed tomography angiography (CTA) and PAM with associated aneurysm was found by digital subtraction angiography (DSA). In view of the distribution of blood and the location of aneurysms, the aneurysm rupture was the most likely to be considered. Based on the involvement of the lesion in the distal blood supply, only the aneurysm was clamped during the operation. It used to be consider that PAM is safety, because of the presentation and natural history of previously reported cases. Through the cases we reported, we have doubted about "the benign natural history" and discussed its treatment. PAM can promote the formation of aneurysms and should be reviewed regularly. The surgical indications for PAM patients with aneurysm formation need to be further clarified. Management of PAM patients with ruptured aneurysm is the same as that of ruptured aneurysm. Whether there are indications needed to treat simple arterial malformations remains to be further elucidated with the multicenter, randomized controlled studies on this disease.
