Internal jugular vein valve incompetence and intracranial venous anatomy in transient global amnesia.
BACKGROUND Recently a causal relation between internal jugular vein valve incompetence (IJVVI) and transient global amnesia (TGA) has been suggested. IJVVI is postulated to provoke a transient mesiotemporal ischaemia by venous congestion. This mechanism requires a patent venous pathway from the affected IJV through the transverse sinus, confluens, straight sinus (SS), vein of Galen into the bas...
متن کاملDeterminants and clinical significance of jugular venous valve competence.
We studied the function of right internal jugular vein valves during cardiac catheterization in 32 patients and external jugular vein valves in vitro from 13 dogs. Patients with normal central venous pressure had competent valves during cough-induced transvalvular pressure gradients of 52.4 +/- 8.6 mm Hg. Ten of 15 patients with elevated central venous pressure had either incompetent or absent ...

متن کاملMisplaced left internal jugular venous catheter with an exceptional location
Large numbers of central venous catheters (CVCs) are placed each year in the intensive care units and misplacement occurs frequently. Many critically ill patients require central venous catheterization for multiple and varied reasons. Internal jugular vein (IJV) catheter is one of the most frequent central venous catheters in intensive care units not only in Africa but all over the word. The ri...
متن کاملDilemma during ultrasound‐guided internal jugular venous catheterization
The presence of Internal Jugular Valves can pose a diagnostic and procedural challenge during ultrasound-guided cannulation. After ruling out dissection, thrombus, or ultrasound artifacts, it can still be accessed and successfully cannulated with appropriate precautions including use of Live ultrasound, positioning, use of soft-tipped catheters, and minimizing duration of catheter placement.
