B: Duplex ultrasonography could detect a large and organized thrombus in the vena femoralis communis (VFC) and Vena femoralis superficialis on the right side.
Though the future of duplex ultrasonography is changing, FNAB is still the gold standard by which other modern methods are measured.
Initially, carotid duplex ultrasonography did pick-up a thrombus probably in the false lumen or it could have been an intramural hematoma but dissection was missed.
Duplex ultrasonography is the initial diagnostic test of choice for detecting hemodynamically significant carotid stenosis.
Duplex ultrasonography has now replaced venography as the most widely used diagnostic test for an acute DVT.
Asymptomatic carotid artery stenosis may be identified during routine physical examination by the presence of a carotid bruit (on auscultation) or during carotid duplex ultrasonography screening of high-risk patients, such as coronary artery disease, congestive heart failure, and hypertension, because atherosclerosis is frequently manifest at multiple sites of cardiovascular system (see Table 1).
The foundation also recommends duplex ultrasonography as a less invasive and less expensive alternative when local expertise is available.
A PICC-associated DVT was defined as a symptomatic event prompting a duplex ultrasonography study which confirmed venous thrombosis.
Carotid duplex ultrasonography at that time revealed a 70 to 80% stenosis of the right internal carotid artery (figure).
A tentative diagnosis of psuedoaneurysm can be made by clinical examination and is confirmed by noninvasive duplex ultrasonography.
In addition, separate matrices should be developed not only for physiologic findings obtained from segmental pressure measurements, continuous wave Doppler waveform analysis, plethysmography and/or photoplethysmography, but also for anatomic findings obtained from duplex ultrasonography.
At present, a common diagnostic approach is to perform an initial screening test with duplex ultrasonography, followed by an angiogram for surgical planning.
