In spontaneously breathing patients, the inferior vena cava (IVC) diameter and the IVC Collapsibility Index (IVC-CI) have been shown to correlate with the volume status and central venous pressure (CVP) [4, 5].
In patients with end-stage renal disease receiving chronic hemodialysis therapy, ultrasound to determine IVC diameter and collapsibility may be a helpful tool for estimation of intravascular volume status or "dry weight" [11-16].
Upon completion of the measurements, the location of the IVC formation was marked and plain anteroposterior and lateral radiographs were taken of each cadaver to verify the location of the IVC radiographically.
CECT abdomen and gadolinium-contrast MRI abdomen revealed 6 x 4 cm heterogeneously enhancing mass with delayed washout suggestive of right adrenal malignancy with invasion to right IVC wall leading to narrowing and presence of nonenhancing IVC thrombus extending from the level of renal veins to the level of confluence with hepatic veins (Figure 1).
IVC, based in Freehold, N.J., "is very excited to be able to serve and help build the businesses of Perrigo's vitamin customers," commented company president and chief executive officer Steven Dai.
Transverse and longitudinal diameter of the IVC were measured at subxiphoid level with subxiphoid long axis view at end inspiration and end expiration for estimation of volume status and patients were categorised as having diameter variability of IVC as 15%, 16-40% and > 40%.
The cash purchase will strengthen IVC's position in the U.S.
Secondly IVC plus radiation damaged healthy jejunal cells less than radiation alone.
Ferumoxytol contrast-enhanced magnetic resonance venography (MRV) (2), demonstrated a large infrahepatic caval thrombus extending from the IVC filter down into the bilateral common, external and internal iliac veins and nonocclusive thrombus within the transplant renal vein (Fig.
Through this acquisition, Ferring will use its resources and expertise in the field of assisted reproductive technologies to help reproductive endocrinology practices across the country expand their service offerings to include the IVC procedure, in addition to their current treatment offerings of intrauterine insemination and in vitro fertilization.
LSIVC usually ends at the left renal vein and crosses anteriorly to join the normal pre-hepatic segment of IVC. More rarely cases of LSIVC, possible routes for the return of blood to RA are via the azygos vein to SVC, via the left brachiocephalic vein to the right SVC, or via the hemiazygos vein to PLSVC(3).
