Facial Vein Draining Into External Jugular vein (Case Report)
Purpose: Circulatory system is very important because of injection, Blood transfer and centeral venous catheter insertion. The superficial veins, especially the external jugular vein (EJV) are increasingly being utilized for cannulation to conduct diagnostic procedures or intravenous therapies. The anomalous drainage of veins is of great significance for vascular surgeons and reconstructive sur...
متن کاملColor Doppler flow imaging of the superior ophthalmic vein in dural arteriovenous fistulas.
BACKGROUND AND PURPOSE This article evaluates the intracranial venous hemodynamics of dural arteriovenous fistula (DAVF) on the basis of data from color Doppler flow imaging (CDFI) findings of the superior ophthalmic vein (SOV) and discusses the clinical application of the SOV CDFI to the DAVFs. METHODS We examined the diameter, flow direction, flow waveform, and flow velocity of the SOV usin...
متن کاملPercutaneous embolization of arteriovenous fistulas of the external carotid artery.
Nineteen arteriovenous fistulas of the external carotid branches in 17 patients were treated by a variety of percutaneous transvascular techniques. There were nine females and eight males; 11 fistulas were traumatic in origin, five were "spontaneous," and three were thought to be congenital. The most frequent presenting symptoms were a bruit and thrill, followed by pulsatile tinnitus, pulsatile...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
