recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...

Objective: This study investigated the relationship between the incidence of hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) for chronic portal vein thrombosis (PVT) and the surgical procedures based on the anatomical classification of thrombosis. Methods: In the present retrospective study, 73 consecutive patients were diagnosed with chronic PVT and treat...

A 41-year-old man presented with consciousness disturbance and right hemiparesis. Computed tomography showed a hematoma in the frontal lobe. Left carotid angiography showed a dural arteriovenous fistula (AVF) located in the cranial vault, supplied by the left middle meningeal artery, and drained directly into the cortical vein adjacent to the superior sagittal sinus. Emergency decompressive cra...

BACKGROUND AND PURPOSE Thalamostriate vein (TSV) is an important tributary of the internal cerebral vein, which mainly drains the basal ganglia and deep medulla. The purpose of this study was to explore the anatomic variation and quality of TSV and its smaller tributaries using susceptibility-weighted imaging (SWI). METHODS We acquired SWI images in 40 volunteers on a 3.0T MR system using an ...

The anatomy of the portal vein is usually classified as 3 to 5 patterns and simple compared with the anatomy of the hepatic artery. The variety of portal vein anatomy was examined in 287 living donors for liver transplantation. More than 90% of donors showed a normal bifurcation type; 6% showed the trifurcation type. Only 3% displayed a separate origin of the right paramedian and the right late...

Deep vein thrombosis and pulmonary embolism are major health problems associated with high mortality. Recently, DNA-based neutrophil extracellular traps (NETs) resulting from the release of decondensed chromatin, were found to be part of the thrombus scaffold and to promote coagulation. However, the significance of nuclear decondensation and NET generation in thrombosis is largely unknown. To a...

Purpose: To document the development of central retinal vein occlusion secondary to orbital emphysema following nose blowing. Methods: A 55-year-old male developed central retinal vein occlusion secondary to orbital emphysema following nose blowing in the absence of trauma. Results: With conservative management his central retinal vein occlusion resolved over nine weeks period. Conclusion: The ...

PURPOSE To determine plasma homocysteine and cysteine levels in patients with retinal vein occlusion (RVO) and in healthy subjects and to ascertain whether there are statistically significant differences between patients and control subjects. METHODS In this case-control study, the study group consisted of 75 consecutive patients with RVO: 33 had central retinal vein occlusion (CRVO), and 42 ...

Two cases of aneurysmal malformations of the vein of Galen with later spontaneous thrombosis are reported. Angiograms before thrombosis in both cases showed mural type aneurysmal malformations of the vein of Galen with slow arteriovenous shunts and associated stagnation of contrast in the venous sac secondary to severe outflow restriction. Based on these angiographic findings, the patients were...
