Is doppler ultrasound only way to tell if u have hood circulation in fingers and hands. if not what other tests does vascular surgeon do?

Not the only way: It's not the only way. Arteriogram (contrast media injected into the artery) is more sensitive than doppler determining your arterial patency.

Exam, is one: And this may include tests to occlude and release blood vessels such as allen's test, measuring pulse pressure in the fingers/wrist/ arm and comparing, assessing turgor and refill, and many other exam findings. Advanced studies include imaging ultrasound, mra, angiograms and tests that challenge circulation with cold or drugs.

NO: The most definitive office testing to check for blood flow in the fingers & hands is a segmental pressure study with finger pressures (PRV & doppler waveforms as well). Ultrasound cannot detect very small arteries, such as those in the fingers, so this other study is necessary. If that test is abnormal, then sometime an angiogram will be necessary to examine the disease in further detail.

Angiogram: Ultrasound is a good test for determining if there is appropriate arterial flow to the upper extremity. Up to the level of the wrist it is a very good study, but there are limitations beyond that level as the arteries become very small and hard to see on ultrasound. The finger arteries (digital arteries ) may be best seen on angiography
