Clinical and hemodynamic significance of the greater saphenous vein diameter in chronic venous insufficiency.
HYPOTHESIS As the compliant greater saphenous vein (GSV) adjusts its luminal size to the level of transmural pressure, measurement of its diameter, reflecting the severity of hemodynamic compromise in limbs with GSV reflux, may simplify the hemodynamic criteria of patient selection for saphenectomy. OBJECTIVE To evaluate the clinical significance of GSV diameter determined in the thigh and ca...

15 صفحه اولThe jugular venous pressure revisited.
Assessment of the jugular venous pressure is often inadequately performed and undervalued. Here, we review the physiologic and anatomic basis for the jugular venous pressure, including the discrepancy between right atrial and central venous pressures. We also describe the correct method of evaluating this clinical finding and review the clinical relevance of the jugular venous pressure, especia...
متن کاملDynamics of the pulmonary venous flow in the fetus and its association with vascular diameter.
BACKGROUND The usual positioning of the Doppler sample volume to assess fetal pulmonary vein flow is in the distal portion of the vein, where the vessel diameter is maximal. This study was performed to test the association of the pulmonary vein pulsatility index (PVPI) with the vessel diameter. METHODS AND RESULTS Twenty-three normal fetuses (mean gestational age, 28.6+/-5.3 weeks) were studi...
متن کاملMammographic Images Interpretation Using Neural- Evolutionary Approach
In this paper, we propose a hybrid approach for mammographic images interpretation in order to detect the benign and malignant anomalies. Using a neural evolutionary approach based on the Radial Basis Function neural network (RBF) and the evolutionary strategy (ES). After applying the growing region algorithm in segmentation stage, the RBF neural network detects the suspect regions. The inferen...
