BACKGROUND Evaluation of patient's dry weight remains challenging in chronic hemodialysis (HD) especially in children. Inferior Vena Cava (IVC) measurement was reported useful to assess fluid overload both in adults and children. METHODS We performed a monocentric prospective study to evaluate the relation between predialytic IVC diameter measurements and hydration status evaluated by physici...

conclusions the abovementioned ivc ultrasonographic criteria for hemodynamic congestion appear clearly inconsistent. alternatively, a sequential or simultaneous combination of clinical scores of congestion, ivc ultrasonographic indices, and circulating levels of natriuretic peptides could be warranted. background among the indices able to replace invasive central venous pressure (cvp) measureme...

BACKGROUND Lack of conduit growth potential and thrombogenicity are the main drawbacks of the extracardiac Fontan operation (ECFO). Optimal size of the conduit according to the patients age and inferior vena cava diameter has not been established. OBJECTIVES We set out to ascertain whether the optimal dimensions of the conduit could be determined before an ECFO. METHODS Actual and expected ...

We evaluated the usefulness of measurements of the inferior vena cava (IVC) diameters on abdominal echograms as an indicator of changes of venous return in subjects with orthostatic intolerance (OI) induced by simulated microgravity. We performed a standing test and recorded the IVC diameters on abdominal echograms in 12 subjects placed on a 20-day 6 degrees head-down-tilt bed-rest experiment. ...

Inferior vena cava (IVC) diameter change on limited transthoracic echocardiogram (LTTE) can provide a useful guide of fluid status evaluation in critically ill patients. Institutional review board approval was obtained. Prospective evaluation of hemodynamic status was performed in hypotensive patients via LTTE. Images were obtained using an ultrasound machine without M-mode capability. Qualita...

Diameter of IVC on CT axial section is a important predictor of hypotension in blunt abdominal trauma. CT scan of abdomen is usually requested whenever there is hemoperitoneum/ free fluid noted on FAST USG imaging in emergency department. The diameter of IVC was measured at infrarenal part. In our review of 25 cases of MDCT abdomen in blunt abdominal trauma, 40% of the cases had FIVC and there ...

BACKGROUND Information on anatomy of intrahepatic inferior vena cava (IVC) and hepatic vein openings in it is limited. METHODS We studied the retrohepatic segment of IVC and hepatic vein openings in it in 69 livers obtained from cadavers. The retrohepatic portion of the IVC was opened posteriorly by a vertical cut, the exposed surface was divided into 12 quadrants and the position, size, and ...

OBJECTIVE Paucity of data exists between mean right atrial pressure (RAP) and inferior vena cava (IVC) size and collapsibility in pediatric patients with congenital heart disease. METHODS In a prospective study, fifty consecutive pediatric patients with different congenital heart diseases who had right side cardiac catheterization were studied, comparing right atrial pressure with simultaneou...

BACKGROUND The inferior vena cava (IVC) diameter and degree of inspiratory collapse are used as echocardiographic indices in the estimation of right atrial pressure. Brain-natriuretic peptides (BNPs) are established biomarkers of myocardial wall stress. There is no information available regarding the association between the IVC diameter and BNPs in patients with heart failure and various degree...
