Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Would 3 ultrasounds of the leg miss a dvt?

Would 3 ultrasounds of the leg miss a dvt?

Ultrasound and DVT: A venous duplex ultrasound is the most accurate test to evaluate for DVT between the lower calf and the groin. The accuracy of the test usually depends on the machine used and the expertise of the ultrasonographer and the interpreter of the exam. 3 negative ultrasounds is certainly strong evidence that no clot would exist between the areas examined. Clots, however, can occur in other areas. ...Read more

2 d-dimers & ultrasounds in 1 week both say negative for dvt. But still have pain and worried I have DVT and they missed it. Should I worry?

2 d-dimers & ultrasounds in 1 week both say negative for dvt. But still have pain and worried I have DVT and they missed it. Should I worry?

Very Very Unlikely: You have had two ultrasound exams and 2 d dimers and oth negative. I think DVT has been ruled out not ince but twicethere may be some other cause of your leg pain. Discuss with your doctor and follow with his/her advice
dvt will not be missed on two tests.
It is highly likely that your leg pain is from dvt. ...Read more

Could an ultrasound scan miss a DVT as iam at high risk of a DVT and is 422 high for a d dimer test?

Could an ultrasound scan miss a DVT as iam at high risk of a DVT and is 422 high for a d dimer test?

Ultrasound for DVT: Ultrasound for lower extremity DVT's have great sensitivity and specificity meaning they are very good at picking up a DVT. There is a 2% chance of somebody having a negative scan and having one found 1 week later according to studies, although repeating it is often done if there is strong suspicion. D-dimer values are not universal so that may be high but values can be high in a lot of disease. ...Read more

What to do if I have a possible dvt, have had an ultrasound, it did not show, has anyone experienced this?

Ultrasound can miss: A venous doppler ultrasound is good test for finding a dvt. However it is possible that it can miss a small or incomplete dvt. This is not an uncommon event so if you still have symptoms and think it might have missed a DVT follow up with you doctor to discuss options such a repeat test or other tests. ...Read more

Please tell me, could a free clinic do an DVT ultrasound?

Not in the clinic: Most free clinics are not capable of doing a DVT ultrasound but they can refer you to a diagnostic facility or an hospital out patient department whwre it can be done and may be done under charity care if you qualify for charity care. Discuss the options with the doctors at the free clinic as they have the knowledge where it can be done only if it is medically indicated. ...Read more

Should a known dvt in the leg be monitored with regular ultrasounds to ensure dvt has not moved or got bigger or no new dvt's have developed?

Not useful: The DVT can take up to 6 months to dissolve completely on blood thinners (Coumadin or 1 of the newer agents) for the time period specified by your doctor. While ultrasound is useful in detecting a DVT (due to Doppler), it is less useful in showing how big/small the clot is over time. Your best bet is warfarin: that has shown to prevent migration of even small flecks of the clot. Se HealthTap Prime ...Read more

My leg been hurting for 3 weeks from my calf up. .... 2 ultrasounds came back negative for dvt. I'm worried are these test pretty accurate? Help

My leg been hurting for 3 weeks from my calf up. .... 2 ultrasounds came back negative for dvt. I'm worried are these test pretty accurate? Help

They are: They are highly accurate for detecting a blood clot in the leg, 97% accurate by most studies which is excellent. There are many causes of leg pain, and in fact, a clot typically won't cause pain unless the vessel becomes inflamed. A clot in the leg most often manifests as new significant swelling of one leg relative to the other, often after a period of immobilization such as a long flight. ...Read more

Pinch feeling in same spot of inner thigh. I've had ultrasounds but still scared of dvt. What could this be.

Pinch feeling in same spot of inner thigh. I've had ultrasounds but still scared of dvt. What could this be.

Doubt dvt: What you have described is unlikely a dvt. The "inner thigh" is a big region but in my view any leg pain should lead ones doc to rule out a 'pinched' or irritated nerve. You did not mention back pain but we have all seen nerve root compression with little or no back symptoms. This said, you are very young to have this as a problem but I would still rtulle it out. ...Read more

What can cause deep calf pain?, I've had it for a month and its been getting worse. I had an ultrasound 2days ago to rule out DVT that was clear.

Calf pain: Many things can cause calf pain aside from a blood clot. Venous insufficiency, arterial disease, lymph-edema, sprains, strains to name a few. I would recommend evaluation by your primary care physician ...Read more

2 ultrasounds in a week 3 ddimers of 307. Dr says no dvt. I still have leg pain after 2 weeks. What are chances it's still a clot? Worried.

2 ultrasounds in a week 3 ddimers of 307. Dr says no dvt. I still have leg pain after 2 weeks. What are chances it's still a clot? Worried.

Needs further eval.: D-dimer is a very non specific blood test. A negative d-dimer and a negative venous ultrasound rule out DVT. Your leg pain does not seem to go along with a DVT especially with 2 normal ultrasounds. Since the d-dimer can be elevated for many reasons, a ct of the iliac and proximal femoral veins would complete your evaluation and definitively make or rule out the diagnosis. ...Read more

I had a ultrasound of the leg cause we had a scare that it could be a dvt. But they found a poppliteal lymph node that is painful. Should I worry?

Do not worry: An ultrasound is the gold standard for evaluation of a clot from the groin to below the knee. Since it did not show dvt, you do not have any clots which would have been a worry. A popliteal lymph could very well be a normal finding and could also be the result of any inflammation in your leg. Follow up with your md. ...Read more

4 yrs. Ago had leg pain, ultrasound performed and told no DVT. Now seeing report says lesser saphenous occluded, should I be worried,? no one told me!

Not a lot: The saphenous is a superficial vein, and not DVT.
However, any clot is abnormal and you should be evaluated for platelet function, clotting issues, varicose veins.
The cause of your superficial venous thrombus may still be important in your life!
While no DVT we generally would tell someone about any abnormality.
It may also have been very chronic and scarred at the time. ...Read more

You will need a: Physician's order to obtain a repeat and if you are insured it is unlikely that the second one will be paid for. In other words you will have a big bill to pay. It is not reasonable to obtain a second study as the likelihood of it being any different is extremely small. Talk to your health care provider about your concerns. ...Read more

2 ultrasounds for DVT were negative 2 weeks ago. Constant pain in calf/ back of knee for a month. The last 3 days leg has started to get swollen?

Get a vascular doc: Consultation. I am not sure if you smoke, but if so it may be Buerger's disease which is clots in your arteries and not veins. Maybe Baker's cyst. This is definitely not a good thing. Not sure if both legs are swelling or one, but may want to also get checked out for any heart issues. ...Read more

Got PE 5 weeks ago put on blood thinners then 2 weeks ago got new clots DVT in arm next to picc repeat ultrasound they got bigger how this possible?

DVT: DVT can re-occur in the presence of predisposing factoors like the PICC line, fractures/ immobilization and hereditary anticoagulant factors deficiency or malgnancy or use of contraceptive with smoking. Expansion of the Thrombus may likely be due inadequate thrombolysis. Use of blood thinners may be inadequate. If coumadin (warfarin) will need to be in therapeutic range to be effective.

Have pain in left leg for a month. Negative d dimer and ultrasound but now a charley horse/knot feeling woke me up and won't go away. Could it be dvt?

Very unlikely to be.: With a negative d-dimer you're more likely to be suffering from muscle spasms, particularly given your symptoms of Charlie horse/knot. If your symptoms do not resolve with adequate hydration, warm compresses, light massage, and other soothing measures, see your doctor for diagnosis and treatment. ...Read more

Pain in rtLeg, I have varicose veins, a few of them. I'm 22 and I'm on BC. Had ultrasound done few months ago. Normal. Should I get another done? DVT?

DVT unlikely: If you had pain and a prior US was negative - a repeat is not likely to be different. 22 is youg for an unprovoked DVT unless you have a family history of clots or are smoking. No mention of where your pain is located, but more likely to be musculoskeletal. Superficial varicose veins have only weak relation to DVT. ...Read more
