1/148. Antiphospholipid antibodies syndrome in 'stroke in young'.

    Antiphospholipid antibodies syndrome has emerged as an important entity responsible for stroke in young. Seven cases of young stroke (< 40 years of age) with mean age of 30.1 years (age range 25-39 years, 2 males and 5 females), who tested positive for antiphospholipid antibodies are being reported. All subjects had completed strokes. Six had arterial ischaemic and one patient had venous stroke. One patient suffered from four episodes, three ischaemic and one intracerebral haemorrhage. Two patients suffered from foetal loss. Generalised tonic clonic seizures occurred in three patients. Deep vein thrombosis was observed in one case. thrombocytopenia was not observed in any case. All the patients had elevated anticardiolipin antibodies (aCL) IgM or IgG, while Lupus anticoagulant (LA) was elevated in 4 cases. Six cases belonged to primary antiphospholipid antibodies syndrome and one to lupus like illness. Oral anticoagulants were administered to maintain a high intensity international normalized ratio (INR). No recurrences were observed during a follow up period of 6-18 months.

2/148. Unilateral congenital cerebral venous dysgenesis.

    I report a 30-year-old woman with congenital cerebral venous dysgenesis with absence of the internal cerebral and basal veins and most of the cortical veins. Unlike the more common bilateral picture, she had involvement only on the left side, which delayed presentation and gave relatively mild symptoms. The embryological mechanism and differential diagnosis of unilateral absence of the internal cerebral, basal and cortical veins are discussed.

3/148. Computerized tomography: abnormal intracerebral collections of blood in children.

    Three children with unusual abnormal intracerebral collections of blood were examined by computerized tomography. These cases demonstrate the complementary relationship of this technique with other neuroradiological diagnostic methods. An intracerebral aneurysm and an arteriovenous malformation of the vein of Galen are demonstrated on computerized tomograms.

4/148. Can intravascular lymphomatosis mimic sinus thrombosis? A case report with 8 months' follow-up and fatal outcome.

    We report a case of intravascular lymphomatosis of the brain with 8 months' follow-up and fatal outcome. Several MRI investigations revealed variegated, rapidly changing infarct-like lesions and invasion of the walls of the superior sagittal sinus and deep veins. When disturbances of the venous outflow are detected with multifocal infarct-like lesions, intravascular lymphomatosis should be considered in the differential diagnosis. brain biopsy may ensure the proper diagnosis ante mortem, but failure of biopsy is frequent, as in our case.

5/148. Extensive radiculopathy: a manifestation of intracranial hypertension.

    We report two patients with severe radiculopathy due to elevated intracranial pressure (ICP) resulting from idiopathic intracranial hypertension (IHH) in one, and cerebral venous sinus thrombosis (CVT) in the other. Our aim is to document this unique association, which escaped diagnosis in both patients.

6/148. Case control study of cerebrovascular damage defined by magnetic resonance imaging in patients with OSA and normal matched control subjects.

    STUDY OBJECTIVES: To assess whether MRI detectable evidence of silent cerebrovascular disease is more prevalent in patients with obstructive sleep apnea (OSA) when compared to carefully matched control subjects. DESIGN AND SETTING: Case-control study of patients with OSA attending a specialist sleep clinic and matched control subjects drawn from the normal community. PARTICIPANTS: Forty-five sleep clinic patients with moderate to severe OSA and excessive daytime sleepiness, matched to 45 control subjects without excessive sleepiness or evidence of OSA on a sleep study. Matched variables included age, body mass index (BMI), alcohol and cigarette consumption, treated hypertension, and ischaemic heart disease. INTERVENTIONS: N/A MEASUREMENTS AND RESULTS: All subjects underwent 24-hour ambulatory blood pressure recordings (before treatment in OSA patients) and sagittal T1, axial T2, and coronal dual echo cerebral MRI imaging to detect clinically silent abnormalities related to hypertensive cerebrovascular disease; areas of high signal foci in deep white matter (DWM), lacunae, and periventricular hyperintensity. Lacunae/high signal foci in DWM and/or periventricular hyperintensity were present in 15 (33%) OSA subjects and 16 (35%) controls, despite significant increases in mean daytime diastolic blood pressure (4.6mmHg, p<0.05), and both nighttime diastolic (7.2mmHg, p<0.001) and systolic blood pressures (9.2mmHg, p<0.05) in OSA subjects. These data exclude more than a 17% excess prevalence of MRI detected minor cerebrovascular disease in the OSA patients, with 95% confidence. CONCLUSIONS: Sub-clinical cerebrovascular disease is prevalent in both clinic patients with OSA and their matched control subjects. Despite the increased arterial blood pressures, there is, however, no apparent excess of MRI-evident subclinical cerebrovascular disease in patients with OSA compared to appropriately matched control subjects.

7/148. Transient postoperative occlusion of the superficial temporal--middle cerebral artery branch anastomosis: spasm, swelling, or thrombosis.

    Ten superficial temporal-middle cerebral artery branch anastomoses were followed by postoperatvie angiograms. The early angiograms revealed patent anastomosis in six patients. In two patients the superficila temporal artery was severely narrowed and tapered and the cerebral arteries were not visualized. In one the superficial temporal artery was not significantly narrowed but was only patent extracranically. In the remaining patient, the superficial temporal artery was completely occluded. The late angiograms showed the patency of the six originally patent anastomoses, and also complete patency of the three anastomoses in which the cerebral arteries were not visualized.

8/148. cerebrovascular disorders in children with the factor v Leiden mutation.

    Since 1995, at least 128 children with a cerebrovascular disorder, cerebral palsy, or both and the factor v Leiden mutation have been reported. The majority of these strokes were in the first year of life, many of them in the perinatal period. Two thirds had an additional exogenous risk factor for thrombosis, and 42% had another recognized endogenous prothrombotic risk factor in combination with the mutation. We review the association of the factor v Leiden mutation and a cerebrovascular disorder in children younger than 16 years of age and describe the clinical features of 8 children with cerebral palsy and the Leiden mutation. This mutation should be considered in the evaluation of children with a stroke or its sequelae, including infants with perinatal stroke.

9/148. Peripheral hemodialysis shunt with intracranial venous congestion.

    BACKGROUND: Intracranial venous congestion is often caused by local venous thrombosis or brain arteriovenous fistulas. Hemodialysis shunts are known to cause venous enlargement in the arm or chest but have not been related to intracranial vascular pathology. Case Description- A 59-year-old woman who presented with increasing headache, gait instability, and memory loss was a renal transplant recipient who still carried a left upper arm shunt. Cranial CT scan showed enlarged veins in the posterior fossa with incipient hydrocephalus. Extracranial duplex sonography revealed reversed flow in the left internal jugular vein, which normalized on cuff inflation around the shunt-carrying arm. The reversed flow, intracranial venous congestion, and neurological status improved after surgical shunt ligation. CONCLUSIONS: To our knowledge, this is the first case description of an intracranial venous outflow obstruction caused by a peripheral arteriovenous shunt.

10/148. Cerebrovascular complication associated with pulmonary vein ablation.

    INTRODUCTION: Radiofrequency (RF) ablation has become an established treatment modality for patients with paroxysmal atrial fibrillation (AF). A principal limitation of RF catheter ablation is the risk of thromboembolism. stroke as a complication after ablation of triggers of AF has not been previously reported. methods AND RESULTS: Fifty-six patients underwent RF ablation for a focal source of AF. Forty-nine patients (86%) had AF triggers in > or = 1 pulmonary vein. Mean procedure time was 227 /- 74 minutes. Cerebrovascular event occurred in 3 (5%) patients, all >60 years old. Two of the three patients had a prior history of transient ischemic attacks. CONCLUSION: The risk of stroke from RF ablation may be higher in paroxysmal AF patients with prior transient ischemic attack.
