This report documents the treatment of a giant aneurysm of the internal carotid artery bifurcation with a fistula to the cavernous sinus, which appeared following closed head trauma. A 39-year-old man suffered from a blunt head trauma in an automobile accident. Two weeks after the trauma, progressive chemosis of left eye was presented. Four months after the trauma, digital subtraction angiography showed an internal carotid artery bifurcation aneurysm, with drainage into the cavernous sinus. The lesion was successfully obliterated with preservation of the parent artery by using coils in conjunction with Onyx. Follow-up angiography obtained 3 months postoperatively revealed persistent obliteration of the aneurysm and fistula as well as patency of the parent artery. Endovascular treatment involving the use of coils combined with Onyx appears to be a feasible and effective option for treatment of this hard-to-treat lesion.

Here we report a case of central retinal artery occlusion after chiropractic manipulation on the neck. A 49-year old man presented at the hospital because of sudden visual loss in his right eye after chiropractic neck manipulation. He had received chiropractic manipulation of the neck by a chiropractor eight days prior. When he first visited us, his best corrected visual acuity in his right eye was hand motion. A full ophthalmic examination was performed. There was cherry-red spot in the macula in his right eye. We performed a fluorescein angiogram and cervical color Doppler. The arterio-venous transit time in the fluorescein angiogram was delayed, and we detected stenosis of the right internal carotid artery with diffuse atherosclerotic plaques in the right common carotid artery. We prescribed ginko biloba extract (Tanamin). Three years after his first visit, the best corrected visual acuity of his right eye was 20 / 200.

We report a case of pituitary apoplexy resulting in right internal carotid artery occlusion accompanied by hemiplegia and lethargy. A 43-yr-old man presented with a sudden onset of severe headache, visual disturbance and left hemiplegia. Investigations revealed a nodular mass, located in the sella and suprasellar portion and accompanied by compression of the optic chiasm. The mass compressed the bilateral cavernous sinuses, resulting in the obliteration of the cavernous portion of the right internal carotid artery. A border zone infarct in the right fronto-parietal region was found. Transsphenoidal tumor decompression following conservative therapy with fluid replacement and steroids was performed. Pathological examination revealed an almost completely infarcted pituitary adenoma. The patient's vision improved immediately after the decompression, and the motor weakness improved to grade IV+ within six months after the operation. Pituitary apoplexy resulting in internal carotid artery occlusion is rare. However, clinicians should be aware of the possibility and the appropriate management of such an occurrence.

BACKGROUND/AIMS: Non-alcoholic fatty liver disease (NAFLD) is closely associated with abdominal obesity, dyslipidemia, hypertension, and Type 2 diabetes, which are all features of the metabolic syndrome. The aim of the present study was to elucidate whether NAFLD is associated with carotid atherosclerosis. METHODS: The study population comprised 659 subjects without hepatitis B and C infections and who did not consume alcohol. Fatty infiltrations of liver were detected by abdominal ultrasonography, and intima-media thickness (IMT) and plaque prevalence were estimated by carotid ultrasonography. RESULTS: The mean values of systolic and diastolic pressures, body mass index (BMI), aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase, uric acid, total cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol, fasting glucose, fasting insulin, homeostasis model of assessment (HOMA) index, hemoglobin A1c, and plasminogen activator inhibitor-1 differed significantly between patients with NAFLD (n=314) and normal controls (n=345). The carotid IMT was 0.817+/-0.212 (mean+/-SD) mm in patients with NAFLD and 0.757+/-0.198 mm in normal controls (p<0.001). The prevalence of carotid plaques was higher in patients with NAFLD (26.4%) than in normal controls (15.9%) (p<0.001). This association persisted significantly after adjusting for age, sex, BMI, HOMA index and individual factors of metabolic syndrome by multiple logistic regression analysis. CONCLUSIONS: Patients with NAFLD are at a high risk of carotid atherosclerosis regardless of metabolic syndrome and classical cardiovascular risk factors. Therefore, the detection of NAFLD should alert to the existence of an increased cardiovascular risk. Moreover, NAFLD might be an independent risk factor for cardiovascular disease.

BACKGROUND/AIMS: The CHADS2 score, used to predict the risk of ischemic stroke in atrial fibrillation (AF) patients, has been reported recently to predict ischemic stroke in patients with coronary heart disease, regardless of the presence of AF. However, little data are available regarding the relationship between the CHADS2 score and cardiovascular outcomes. METHODS: This was a retrospective study on 104 patients admitted for acute coronary syndrome (ACS) who underwent coronary angiography, carotid ultrasound, and transthoracic echocardiography. RESULTS: The mean age of the subjects was 60.1 +/- 12.6 years. The CHADS2 score was as follows: 0 in 46 patients (44.2%), 1 in 31 (29.8%), 2 in 18 (17.3%), and > or = 3 in 9 patients (8.7%). The left atrial volume index (LAVi) showed a positive correlation with the CHADS2 score (20.8 +/- 5.9 for 0; 23.2 +/- 6.7 for 1; 26.6 +/- 10.8 for 2; and 30.3 +/- 8.3 mL/m2 for > or =3; p = 0.001). The average carotid total plaque area was significantly increased with CHADS2 scores > or = 2 (4.97 +/- 7.17 mm2 vs. 15.52 +/- 14.61 mm2; p = 0.002). Eight patients experienced cardiovascular or cerebrovascular (CCV) events during a mean evaluation period of 662 days. A CHADS2 score > or = 3 was related to an increase in the risk of CCV events (hazard ratio, 14.31; 95% confidence interval, 3.53 to 58.06). Furthermore, LAVi and the severity of coronary artery obstructive disease were also associated with an increased risk of CCV events. CONCLUSIONS: The CHADS2 score may be a useful prognostic tool for predicting CCV events in ACS patients with documented coronary artery disease.

We investigated the association of depressive symptoms with carotid intima-media thickness (IMT) and plaques in the general Korean population. A total of 7,554 Korean males and females aged 45-74 yr who were free from cardiovascular diseases were included in the analyses. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale (CES-D). Subjects with a score of > or =16 were classified as having clinically significant depressive symptoms. Carotid ultrasonography was used to measure mean carotid IMT (C-IMT) and to determine the presence of plaques. A significant association between depressive symptoms and C-IMT was observed only in females. After adjustment for established cardiovascular risk factors, females with depressive symptoms had significantly greater C-IMT than females without depressive symptoms (mean difference 0.011+/-0.004 mm; 95% confidence interval, 0.003-0.019 mm). Compared with controls, the fully adjusted risk of females with depressive symptoms for abnormal C-IMT (> or =1.0 mm) was significant (odds ratio, 1.63; 95% confidence interval, 1.16-2.30). No significant association between depressive symptoms and carotid plaques was observed in either gender. This study shows a significant association between depressive symptoms and C-IMT in middle-aged and older females.

The aim of this study was to determine the normal value of brachial-ankle pulse wave velocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) according to age group, gender, and the presence of cardiovascular risk factors in healthy Koreans, and to investigate the association between PWV and risk factors such as prehypertension, dyslipidemia, smoking, and obesity. We measured an arterial stiffness in 110 normal subjects who were 20 to 69 yr-old with no evidence of cardiovascular disease, cerebrovascular accident or diabetes mellitus. The mean values of baPWV and cfPWV were 12.6 (+/-2.27) m/sec (13.1+/-1.85 in men, 12.1+/-2.51 in women; P=0.019) and 8.70 (+/-1.99) m/sec (9.34+/-2.13 in men, 8.15+/-1.69 in women; P=0.001), respectively. The distribution of baPWV (P<0.001) and cfPWV (P=0.006) by age group and gender showed an increase in the mean value with age. Men had higher baPWV and cfPWV than women (P<0.001). There was a difference in baPWV and cfPWV by age group on prehypertension, dyslipidemia, current smoking, or obesity (P<0.001). In multiple linear regression, age and prehypertension were highly associated with baPWV and cfPWV after adjustment for confounding factors (P<0.001). The present study showed that baPWV and cfPWV are associated with age, gender, and prehypertension in healthy Koreans.
