We report a case of polycythemia vera combined with coagulation disorder. The patient was 54 years old man who complained of continuous bleeding after incision of skin abscess 20days ago. Laboratory tests were revealed prolonged aPTT and slightly prolonged PT. Coagulation factor, I, VIII, IX, XI and fibrinogen decreased, however FDP did not increased. It appears that patient with polycythemia vera have chronic activation of coagulation system, probably initiated by activation of factor XII. Platelet aggregation test to ADP, collagen, epinephrine was also revealed poor response.

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.

BACKGROUND: The most important acute complication of percutaneous transluminal coronary angioplasty (PTCA) is abrupt closure by dissection and thrombus, which account for the majority of deaths and emergency coronary artery bypass procedures associated with PTCA. We sought to determine the relationship between clinical, angiographic characteristics and abrupt thrombotic closure related to coronary intervention. METHODS: One hundred thirty two patients (61.6+/-8.0 year, 98 male) underwent PTCA or stenting under the diagnosis of acute myocardial infarction were analyzed at Chonnam University Hospital between Jan '97 and Jun '98. Patients were divided into two groups, one, 14 patients (Group A, 61.7+/-8.0 year, 9 male), who developed thrombotic occlusion, and the other, 118 patients (Group B, 61.5+/-8.0 year, 89 male) who did not develop abrupt closure related to the coronary intervention. RESULT: There were no significant differences in age, sex, risk factors, activated partial thromboplastin time, fibrinogen, erythrocyte sedimentation rate, C-reactive protein, location of lesion, branch involvement, lesion severity, AHA/ACC morphology between two groups. The incidence of intra-coronary thrombus was greater in Group A than in Group B (44% vs. 2%, p=0.025). Acute thrombotic occlusion related to the coronary interventions developed more frequently in the lesions within two days after the symptomatic onset (55% vs. 19%, p=0.035) and in the right coronary artery (RCA) lesions (55% vs. 24%, p=0.041). CONCLUSION: Predictors of abrupt thrombotic occlusion during coronary intervention in patients with acute myocardial infarction are intracoronary thrombus, earlier intervenion within 2 days after onset of aucte myocardial infarction and RCA lesion.

BACKGROUND AND OBJECTIVES: One of the major limitations in coronary intervention is restenosis. This study was aimed to identify clinical, angiographic and procedural factors, which may be related to the second restenosis (SR). MATERIALS AND METHOD: We studied 101 patients who underwent more than two follow-up coronary angiograms after two coronary interventions between Jan 1996 and Dec 1998 in Chonnam University Hospital (out of 4092 total coronary interventions in 3030 patients during the same period). The patients were divided into two groups according to the evidence of second restenosis (SR). Fifty two patients (Group A: 56.6+/-9.9 year, M: F=44:8) who had SR, and the other 49 patients (Group B: 53.8+/-8.5 year, M: F=44: 5) were analyzed. Clinical features, angiographic characteristics, coronary interventional procedures, and other risk factors were compared between two groups by univariate analysis and multivariate stepwise logistic regression analysis for the predictive factors of second restenosis. RESULTS: 1) The clinical variables of age, sex, clinical diagnosis, and risk factors were not different between two groups. 2) The lesion types severer than B2 by AHA/ACC classification were associated with SR (p<0.05). 3) Recurrent angina as an indication for follow up angiography was associated with SR (p<0.01). CONCLUSION: The predictive factors associated with SR were patient's subjective symptom and lesion severer than type B2 according to AHA/ACC classification.

PURPOSE: To compare the various imaging techniques including application of magnetization transfer(MT), administration of IV contrast materials, and imaging time after injection of contrast materials in 3D time-of-flight(TOF) cerebral magnetic resonance angiography(MRA) in normal volunteers. MATERIALS AND METHODS: Each of 11 healthy volunteers was prospectively studied with 3D TOF cerebral MRA using various imaging parameters. Various parameters of 3D TOF MRA were 1) pre-enhanced magnetization transfer(MT), 2) postenhanced MT, immediate phase, 3) postenhanced MT, 10-minutes delayed phase, 4) postenhanced MT, 20-minutes delayed phase, 5) pre-enhanced non-MT, 6) postenhanced non-MT, immediate phase, 7) postenhanced non-MT, 10-minutes delayed phase, 8) postenhanced non-MT, 20-minutes delayed phase. Image qualities of various parameters were compared with regard to depiction of cerebral arteries and veins by visual assessment For statistical analysis paired t-test was used. RESULTS: In pre-enhanced MRA, images with MT mode were better in arterial visualization than those with :n0n-MT mode(p<0.01). Postenhanced MT and non-MT images were better in arterial and venous visualization !than pre-enhanced MT and non-MT images(p<0.01), respectively. Images obtained immediately after injection of contrast material were better in both arterial and venous visualization than delayed images(p<0.01). CONCLUSION: Postenhanced cerebral 3D TOF MRA with MT obtained immediately after injection of contrast materal is the best to increase visualization of both cerebral arteries and veins, and may be indicated in some cranial vascular diseases.

OBJECTIVE: To investigate the sagittal sacropelvic morphology and balance of the patients with SIJ pain following lumbar fusion. METHODS: Among 452 patients who underwent posterior lumbar interbody fusion between June 2009 and January 2013, patients with postoperative SIJ pain, being responded to SIJ block were enrolled. For a control group, patients matched for sex, age group, the number of fused level and fusion to sacrum were randomly selected. Patients were assessed radiologic parameters including lumbar lordosis, pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS). To evaluate the sagittal sacropelvic morphology and balance, the ratio of PT/PI, SS/PI and PT/SS were analyzed. RESULTS: A total of 28 patients with SIJ pain and 56 patients without SIJ pain were assessed. Postoperatively, SIJ pain group showed significantly greater PT (p=0.02) than non-SIJ pain group. Postoperatively, PT/PI and SS/PI in SIJ pain group was significantly greater and smaller than those in non-SIJ pain group respectively (p=0.03, 0.02, respectively) except for PT/SS (p=0.05). SIJ pain group did not show significant postoperative changes of PT/PI and SS/PI (p=0.09 and 0.08, respectively) while non-SIJ pain group showed significantly decrease of PT/PI (p=0.00) and increase of SS/PI (p=0.00). CONCLUSION: This study presents different sagittal sacropelvic morphology and balance between the patients with/without SIJ pain following lumbar fusion surgery. The patients with SIJ pain showed retroversed pelvis and vertical sacrum while the patients without SIJ pain have similar morphologic features with asymptomatic populations in the literature.
