for Case 1 of venous outflow with tortuosity and aneurysms (arrow) (a).
The possibility of visualizing a precontrast venogram
through a 3D steady-state free precession (SSFP) balanced sequence makes the distinction between veins and lymphatic vessels easier.
Imaging studies recommended are Doppler Ultrasound, hepatic venogram
, MRI of liver, and liver biopsy.
At the corporate level, the number of procedures (venogram
and/or angioplasties, central venous catheter [CVC] insertions, emergency room visits, surgery, and hospitalizations) that were required by the patients to correct extensive problems (AVF damage or failure) was recorded.
All underwent Doppler evaluation for leg thromboses after cast removal, and positive results were confirmed with venograms
. Overall, there were no DVTs among the LMWH prophylaxis group and 7 DVTs (4.3%) in the group without LMWH prophylaxis (P<.006).
Beathard (1998) further recommends a venogram
for clients with previous CVCs to evaluate the patency of the central vein prior to ipsilateral AV access placement.
The VUEPORT enables physicians to rapidly produce a venogram
, or picture of the heart's veins and guides the physician in the delivery of other diagnostic microcatheters or placement of pacing leads.
Their study compared the use of contrast media by physician groups for CT studies, intravenous pyelograms and venograms
. Ionic contrast media was universally administered by 15% of the nonradiologist groups but only 9.8% of the radiologist groups.
If these patients are included in a higher paying category if they have venography, then it will be in the hospital's economic interest to maximize the number o venograms
of the upper extremities demonstrated filling defects of the brachiocephalic and the subclavian veins bilaterally and the SVC proximally.
are a useful radiologic procedure to confirm this finding.
According to Beckmann & Abrams, renal phlebograms (Venograms
) are commonly indicated in reno-vascular hypertension or in the cases of renal or retro-peritoneal malignancy or in thrombosis or suspected variations of renal vein.
