Clinical Features of Stroke in Patients Undergoing Maintenance Dialysis / 대한신장학회잡지

Cardiovascular and cerebrovascular diseases are important causes of death in patients receiving maintenance dialysis. Stroke occurred in high rate with the tendency to worsen prognosis. Also many patients with chronic renal failure(CRF) showed a high risk for stroke. From March 1985 to March 1999, at Wonju Christian Hospital, we investigated retrospectively risk factors, clinical appearance and prognosis for stroke in 20 patients with CRF who undergoing maintenance dialysis. The stroke occurred in nine male and eleven female with a mean age of 49.95+/-9.19 years. Seventeen patients underwent hemodialysis and three patients underwent peritoneal dialysis. Mean duration of dialysis was 50.05+/-34.68 months. Causes of CRF were as follows : 55% glomerulonephritis, 20% diabetes mellitus, 5% polycystic kidney and 20% unknown origin. At the time of stroke, serum protein level was 6.68+/-0.86mg/dL, albumin 3.38+/-0.87g/dL, cholesterol 160.25+/-43.34mg/dL, HDL-cholesterol 41.41+/-11.86mg/dL. All patients were on antihypertensive medication. Mean systolic blood pressure was 197+/-45mmHg, diastolic blood pressure 114+/-23mmHg. Systolic blood pressure of fourteen cases were more than 180mmHg. During hemodialysis, heparin dosage was an average 2425+/-371.48 IU. The types of stroke were intracerebral hemorrhage (ICH, 75%), subdural hematoma(10%), cerebral infarction(15%). One case developed both cerebral hemorrhage and subarachnoid hemorrhage. The sites of hematoma were basal ganglion-thalamus(60%), and subcortex(33.3%). Of these, nine cases had subsequent intraventricular hemorrhage(IVH). One case involved IVH only. The mean volume of hematoma was 66.42+/-29.92mL. Three cases of cerebral infarction developed in midcerebral arterial territory. Prognoses were as follows : Sixteen patients with cerebral hemorrhage died during hospitalization and one case has been monitored via outpatient department. One patient with cerebral infartion died during hospitalization and two have been discharged after symptom was improved. In conclusion, CRF patients undergoing maintenance dialysis showed higher incidence of ICH, unlike the recent studies which showed a higher rate of cerebral infarction to ICH in the general population. There was a higher incidence of stroke in patients whose blood pressure were poorly controlled. The most common site of ICH was basal ganglia and thalamus which was the same as in the general population. In many cases, it accompanied IVH and showed a higher mortality rate. Therefore, it is thought that aggressive blood pressure control is indicated to reduce mortality caused by stroke during maintenance dialysis.
