PURPOSE: To evaluate abnormal neurosonographic (NSG) findings of thalami and basal ganglia in full term babies with hypoxic-ischemic encephalopathy and to correlate the findings with follow-up studies and prognosis. METHODS: We evaluated 13 full term babies with abnormal NSG findings of thalarni and basal ganglia. NSG was performed within 7 days after clinical abnormalities. Follow-up NSG was done in 11 cases; CT scan in 4 and MRI in 7. We classified NSG findings as diffuse, unilateral, and focal types according to increased echogenicity and evaluated prognosis based on follow-up studies and neurological sequelae. RESULTS: Nine cases of diffuse type had diffuse echogenic changes of bilateral thalami and basal ganglia, slit-like lateral ventricles suggesting cerebral edema, and increased parenchymal echogenicity. In diffuse type, follow-up studies showed more prominent echogencities and ventricular dilatations and cerebromalacia. One case of unilateral type caused by thromboembolism had unilateral echogenicity of right thalamus and basal ganglia with increased echogenicity of the ipsilateral cerebral hemisphere and compression of the lateral ventricle, suggesting cerebral infarction. Follow-up study showed unilateral cystic cerebromalacia. Three cases of focal type had a localized echogenic area in thalamus with lacunar infarction, which decreased in size during follow-up. Among nine cases of diffuse type, one died within 2 days, two were discharged against medical advice, and six had severe neurologic sequelae. One case of unilateral type had a moderate degree of neurologic sequelae. All 3 cases of focal type had normal development. CONCLUSION: Pattems of abnormal echogenicity in thalami and basal ganglia in fullterm infants with hypoxic-ischemic encephalopathy are correlated with the outcome and may be helpful for treatment planning.

PURPOSE: To determine the usefulness of MR urography technique for the evaluation of urinary systems in patients with obstructed urinary tract and normal volunteers with non-obstructed urinary tract after intravenous normal saline and diuretic injection. MATERIALS AND METHODS: Three normal volunteers and 12 patients with urinary tract obstruction [ureteral calculi(n=8), extraurinary mass(n=1), ureteral tumor invasion(n=3)] underwent MR urography using a 1.0T scanner and a 2D non-breath-hold heavily T2-weighted fast spin-echo sequence. These acquisition were postprocessed with a maximum intensity projection (MIP) algorithm. Two acquisitions were performed, the first prior to saline solution infusion following standard MR urography procedures, and the second, within 2-3 minutes of the infusion of 250 ml saline solution followed by 20 mg of Lasix administered intravenously. For this latter, drug-induced MR urography procedures were followed. RESULTS: In healthy volunteers (n=3) and those experiencing partial obstruction (n=4) by a urinary stone, drug-induced MR urography provided better images of the urinary tract than did standard MR urography. In those in whom a urinary stone or tumor had caused complete obstruction (n=8), standard MR urography provided good images, as did drug-induced MR urography. CONCLUSION: In patients with a partially or non-obstructed urinary tract, drug-induced MR urography provided better anatomic and functional details of the kidney and urinary tract than did standard MR urography. In those experiencing complete obstruction of the urinary tract, however, standard or drug-induced MR urography permitted very adequate evaluation of the tract, and drug-induced MR urography was unnecessary.

This is a retrospective clinical and roentgenographic study to measure the correction of deformity and rigidity of Harrington SSI in the stabilization of unstable thoracic and lumbar spine fractures. 35 patients with unstable thoracic and lumbar spine fracture were treated with Harrington SSI from Feb. 1985 to Mar. 1987 in SNUH and 29 patients were followed up for more than 1 year, average 15.6 months. At final follow up of these 29 patients, 73.1% of patients gained neurologic improvement. Measurement of correction of anterior, middle and posterior column height, local kyphosis and anteroposterior offset were 29.7%, 5.2%, 31.2%, 12.8°and 5.3mm and loss of correction of these were 6.5%, 0.1%, 5.8%, 3.1°and 1.1 mm.

PURPOSE: Our purpose in this study is to evaluate the effectiveness of bronchial and nonbronchial systemic arteries for the control of hemoptysis. MATERIALS AND METHODS: Seventy patients with massive or recurrent hemoptysis underwent percutaneous transcatheter embolotherapy between 1991 and 1993. Retrospectively we reviewed 77 cases of bronchial artery embotization and 32 cases of nonbronchial systemic artery embolization in the 70 patients. RESULTS: Immdiate control of hemoptysis was achieved in 33 of 39 patients with massive hemoptysis(84.6%) and 20 of 24 patients with recurrent hemopt ysis(83.3%). In 32 cases, nonbronchial systemic arteries contributed significantly to areas of pathologic pulmonary tissue and frequently were the major arterial supply. CONCLUSION: Bronchial artery embolization is an effective and life saving procedure in non-surgical candidates. Recognition and occlusion of nonbronchial systemic arteries that feed to hypervascular pulmonary lesions is essential for successful percutaneous embolotherapy of hemoptysis.
