Doctor insights on:
It depends: It depends on the clinical situation. Pelvic venography can evaluate for ovarian vein insufficiency (aka pelvic congestion), may-thurner syndrome, or clot in the veins of the pelvis. ...Read more
Contrast and access: Diabetics often have terrible veins to access for peripheral veinography. Ultrasound guided access can help greatly. Once access is obtained, concerns turn to limiting the amount of contrast that is used in order to avoid injury to the kidney function. ...Read more
Usually tilting: Usually a tilting table is used for a venogram of the leg- but not always. Different hospitals and radiologist have different procedures for different circumstances. ...Read more
Vascular studies: It is not uncommon to do venous and arterial studies at the same time. ...Read more
Can be done.: Ascending venogram or simply venogram is used to find blood clots or areas of narrowing / blockage. Access for the contrast injection is in the foot or ankle. Descending venogram is a test for venous insufficiency. A catheter is placed in your arm/neck and positioned in your pelvis. Contrast is injected while you are tiled to a near standing position. Dye going backwards is abnormal. ...Read more
Yes: Yes one leg is examined in its entirety with one venogram ...Read more
Foot veins: Foot veins are normal and increase in size when standing and decrease in size when lying. An ultrasound can be done to assess the foot veins and rarely is a venogram done any more. Usually however, foot veins are evaluated by physical exam since they are under the skin and can be easily examined. See a vein specialist if you have a vein issue. ...Read more
Rarely done these days.
Outpatient Doppler venous duplex exams are non- invasive, highly accurate and economical.
Call the Vascular lab at your hospital or vascular surgeons office and ask.
Usually covered if proper indications to have it done.
Pain, swelling, prior clots, varicosities etc.
If ultrasound and d-dimer are negative the liklihood of DVT is very low. ...Read more
Your physician: Diligently investigated you for possible complication of crohn's disease. Cerebral sinus thrombosis is one of the complication of crohn's disease. If mrv is negative that is reassuring. Once the worst case scenario is excluded, it is better to focus on the common causes of head ache. As you know the causes of head ache are countlesss. Common things being common, better to focus on them. ...Read more
Are magnetic resonance angiogram and venogram usually performed with the posterior view or anterior? Does it depend on symptoms and site of symptoms?
Cross sections of: Body which are reconstructed in software to show any of multiple views, depending on machine, software, technician & radiologist chosen protocols. Symptoms & site of symptoms are not a driving factor in how the scan is performed. These issues are dictated by body anatomy & the construction of the scanning hardware. ...Read more
What to look for: CT venogram is a study for the veins of the body. Looking for something in the veins. Site of injection may be different timing different. CT with contrast has contrast material also. Timing also different ...Read more
NMRIBetterSoftTissue: NMRI = (Nuclear) Magnetic Resonance Imaging tends to be better than CT for soft tissue differentiation but, as always, depends on specific equipment, how the technicians use the controls, contrast used, planning, what is being looked for, physician input to adjust for the clinical issues, the physician reader & what they know about the particular clinical issues being looked for, etc. ...Read more
Can my primary care physician order imaging such as angriogram or venogram, or are they restricted from doing so?
Pop: Any physician can order tests, however it may be beneficial to be first evaluated by a specialist and together decide on an appropriate test based on your symptoms ...Read more
I know venogram is gold standard, but wow accurate is venous ultrasound below the knee? Is it really operator dependent and 50-85% accurate?
Very accurate: Ultrasounds are operator dependent. But below the knee. If the vessels are seen and flow seen no clots. The question is really what to do with clots there. Some treat others don't. The study can be repeated to see if there is progression of the clots. Either way a very good study. Venogram is not without risk ...Read more
Why is it so difficult to get a venogram below the knee? D-dimer and US are not good enough considering I have PV. Self assessment 3 on Well's test
Skill, risk and time:
Venogram is an effective way to evaluate the veins of the leg especially to look for blood clots. Unfortunately we do these tests less often because they are technically more difficult, take more more time and have more risk. IV contrast dye can damage kidneys and cause phlebitis.
So because the done so infrequently the skill get a bit rusty and we prefer newer less invasive methods for diagnosis ...Read more
No, CT spacial image: Detail quality (partially older technology with more improvements over time) remains much superior to MRI. Yet CT is radiation, MRI (actually NMRI) no radiation, but slower, more noise & better at distinguishing soft tissue differences. Yet both only show location of dye in vein, not the vein itself, thus can easily miss issues present but not reflected in dye column. ...Read more
Feel pulse in 7 places between foot + leg. Unilateral swelling posteriorly. US + ABI normal. Have P. Vera + Crohn's. Time for arteriogram + venogram?
Feeling pulse in itself is not a bad thing.
However the swelling needs to be examined to determine next course of action. Need not necessarily be arteriogram/venogram.
The swelling may be nonvascular in nature. ...Read more
What might cause pain in the thigh that seems to move around in buttocks and groin if the doctor suggested an ultrasound and venogram?
Hip, back, etc.: Several things cause pain in those areas: low back problems with irritation of nerve (radiculopathy), groin, obturator hernia, hip degeneration, pelvic disease with irritation of nerves. Evaluation with ultrasound may help identify the problem, but best to start with physical examination. ...Read more
P. Vera. GSV reflux below knee. Tightness in posterior and sides of calf. Tightness remedied w/ elevation. Is this a circulatory issue? Get venogram?
Reflux: Such vein problems can usually be managed nonoperatively with compression stockings and leg elevation. You do not need a venogram to make Dx. Venous duplex &/or PPG in an accredited vascular laboratory can confirm venous insufficiency. Reluctance to perform venogram or venous ablation with Hx P Vera as this makes you prone to clotting which could complicate either. Follow with vascular surgeon. ...Read more
