A perforating vein can become incompetent due to hemodynamic or morphologic causes. Until recently all perforating veins with a diameter exceeding 3 mm at ultrasound exam were considered incontinent(1). Since introduction of duplex doppler and color doppler investigations this hypothesis was temperated because the dilatation of one or more perforating veins was usually observed in chronic venou...

The study conducted on 60 human cadavers preserved in formalin, in the Anatomy Laboratory of the "Victor Babes" University of Medicine and Pharmacy Timisoara, during 2000-2006, observed the internal and external jugular veins from the point of view of their origin, course and affluents. The morphological variability of the jugular veins (external jugular that receives as affluents the facial an...

Overview Varicose veins of the lower extremities are found in the superficial venous system which includes the great saphenous vein (GSV) and the small saphenous vein (SSV), and their tributaries. One-way valves are present in the superficial venous system. These valves prevent backward flow of blood within the vein (reflux) and keep the blood moving toward the heart. The condition of improperl...

To obtain a fundamental knowledge of the morphological relationship between nerve root symptoms and circulatory disorders, the distribution pattern of the veins in the lumbar spinal ganglia from the first to fifth vertebrae was investigated in 5 adult human cadavers (mean age 69.6 years) and 5 human fetuses (mean age 6.6 months). The following results were obtained: 1) In the adults the veins p...

BACKGROUND AND PURPOSE The demonstration of prominent medullary veins in the deep white matter ipsilateral to acute ischemic stroke has been shown to predict poor clinical outcome. We have investigated the prognostic implications of prominent medullary veins in patients with subacute stroke who present outside the therapeutic window for revascularization therapy. MATERIALS AND METHODS Forty-t...

Along the western margin of the Taconic orogen in New York and Vermont, undeformed quartz-calcite veins commonly occur in the belt of melange that formed beneath the westward-advancing Taconic Allochthon during the Middle-Late Ordovician Taconic orogeny. The veins have mineral slickenfibers recording either reverse or normal slip. In New York, the reverse-motion veins recording the latest phase...
