The authors investigated the pineal blood supply in the rat, including microvascularisation, using different methods of vascular corrosion cast technique and two methods of inspection: scanning electron microscopy (SEM) and light microscope (LM). The animals were divided into three groups and injected with two types of casting media. It was found that the pineal gland is highly vascularised. Ar...

RATIONALE Vein of Galen aneurysmal malformation (VGAM) is a rare complex malformation of the cerebral vascular system consisting of arteriovenous shunts between the vein of Galen and the cerebral arteries. PATIENT CONCERNS We present the case of a 31-year-old pregnant woman, para 1, gravida 1. DIAGNOSES At 26 weeks' gestation who was examined for an anechoic mass on the cerebral median midl...

OBJECTIVE To examine the effects of hypertonic/hyperoncotic treatment on physiologic variables and regional cerebral blood flow and to test its neuroprotective efficiency in a model of permanent venous ischemia. DESIGN Randomized prospective study. SETTING University research institute. SUBJECTS Adult male Wistar rats, weighing 359 +/- 54 g (n = 38). INTERVENTIONS Rats were subjected to...

BACKGROUND AND PURPOSE The termination of the superficial middle cerebral vein is classically assimilated to the sphenoid portion of the sphenoparietal sinus. This notion has, however, been challenged in a sometimes confusing literature. The purpose of the present study was to evaluate the actual anatomic relationship existing between the sphenoparietal sinus and the superficial middle cerebral...

High-resolution magnetic resonance venography (HR-MRV) of intracranial subependymal veins using a two-dimensional Fourier-transform time-of-flight technique was performed on normal volunteers and clinical cases of cerebral disease. For the pulse sequence, fast-field-echo sequence was used with the following parameters: TR/TE/flip angle = 34 ms/12 ms/50 deg., 256 x 256 matrix, 1 mm effective sli...

BACKGROUND AND OBJECTIVES Despite inherited thrombophilic risk factors being strongly associated with vein thrombosis, decisions on whether to screen subjects for these factors vary in different clinical settings. DESIGN AND METHODS We calculated the prevalence of inherited thrombophilic risk factors in a large cohort of patients (n=1,238) with different clinical manifestations of vein thromb...

Background: The risk of thrombosis is high in patients with Ulcerative Colitis. main location the extremity and pulmonary vein. Cerebral venous a rare for mortality. One factors developing association surgery, especially during an active phase Colitis (UC), very few studies report cases occurring inactive phase. Hence, it important surgeon to understand thrombosis, cerebral sinus patient. Case:...

BACKGROUND Cerebral venous thrombosis is an uncommon disorder in the general population. However, it has a higher frequency among patients younger than 40 years , patients with thrombophilia and patients that have foreign body such as catheter in their veins or arterial system. CASE DETAILS In this case report, we described the clinical and radiological findings of a patient who developed cer...
