Dural arteriovenous fistulas (AVFs) are uncommon, representing only 10% to 15% of all intracranial AVFs. Here we present the case of a patient with cerebral infarction who experienced a dural AVF after craniotomy for superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery. A 48-year-old man presented with dysarthria and right side hemiparesis. A brain magnetic resonance imaging scan revealed multiple acute infarctions and severe stenosis of the left MCA. Therefore, STA-MCA bypass surgery was performed. A follow-up angiography performed 2 weeks after the surgery showed an abnormal vascular channel from the left middle meningeal artery (MMA) to the middle meningeal vein (MMV) just anterior to the border of the craniotomy margin. This fistula originated from a screw used for cranial fixation. The screw injured the MMA and MMV, and this resulted in the formation of a fistula. The fistula was successfully treated with transarterial embolization. Surgeons should be careful when fixing bones with screws and plates as fistulas can develop if vessels are injured.

Background and Objectives:
The relationship between the hospital percutaneous coronary intervention (PCI) volumes and the in-hospital clinical outcomes of patients with acute myocardial infarction (AMI) remains the subject of debate. This study aimed to determine whether the in-hospital clinical outcomes of patients with AMI in Korea are significantly associated with hospital PCI volumes.
Methods:
We selected and analyzed 17,121 cases of AMI, that is, 8,839 cases of non-ST-segment elevation myocardial infarction and 8,282 cases of ST-segment elevation myocardial infarction, enrolled in the 2014 Korean percutaneous coronary intervention (K-PCI) registry. Patients were divided into 2 groups according to hospital annual PCI volume, that is, to a high-volume group (≥400/year) or a low-volume group (<400/year). Major adverse cardiovascular and cerebrovascular events (MACCEs) were defined as composites of death, cardiac death, non-fatal myocardial infarction (MI), stent thrombosis, stroke, and need for urgent PCI during index admission after PCI.
Results:
Rates of MACCE and non-fatal MI were higher in the low-volume group than in the high-volume group (MACCE: 10.9% vs. 8.6%, p=0.001; non-fatal MI: 4.8% vs. 2.6%, p=0.001, respectively). Multivariate regression analysis showed PCI volume did not independently predict MACCE.
Conclusions
Hospital PCI volume was not found to be an independent predictor of in-hospital clinical outcomes in patients with AMI included in the 2014 K-PCI registry.

BACKGROUND/AIMS: The apolipoprotein B/A-I ratio (ApoB/A-I) is a powerful clinical indicator of atherosclerosis. Although numerous reports have shown the effect of non-alcoholic fatty liver disease (NAFLD) on cardiovascular disease, few reports have examined the relationship between NAFLD and the ApoB/A-I ratio. The aim of the study was to determine the association between NAFLD and the ApoB/A-I ratio in prediabetic patients. METHODS: This cross-sectional study was performed with data obtained from 701 patients (mean age, 47.9+/-9.6 years) diagnosed with prediabetes. Serum lipid profiles including lipoprotein, apolipoprotein, and calculated ApoB/A-I ratio as well as metabolic syndrome parameters such as fasting glucose and insulin were measured in each subject. RESULTS: Among the 701 patients, 340 (48%) had NAFLD. The number of male patients was 490 (NAFLD+, 276; and NAFLD-, 214). The odds ratios for the prevalence of NAFLD increased according to the quartiles of the ApoB/A-I ratio (1.886, 2.245, and 2.587) (p<0.001). CONCLUSIONS: The prevalence of NAFLD correlated with high ApoB/A-I ratio, suggesting that NAFLD increases the risk for atherosclerosis progression in male prediabetic patients.
