Vascular Final Study Guide Part 3

Venous ulcers occur near the lateral malleolus

There is little bleeding with an arterial ulcer

Phlegmasia alba dolens is characterized by severe swelling of the leg

Pregnancy and obesity are causes of primary varicose veins

Hypercoaguability of the blood may be related to myeloproliferative disorders

Virchow's Triad relates to blood stasis, hypercoaguabilty of blood and changes in venous walls.

Chronic hypertension may be a risk factor in the development of DVT

The calf muscle pump mechanism works because of the pressure gradient

Regarding statistical terminology in the evaluation of the accuracy of a particular examination, a false positive measn that the "gold standard" was negative, but the noninvasive ultrasound was positive

When supine, the hydrostatic pressure in the veins of the leg is approximately 15 mm/Hg

When fully distended, the cross sectional area of the vein is greater than that of the artery.

If the patient's brachial pulse is 140/80 mm/Hg, and the ankle pulse is 110/70 mm/Hg, then the AAI will be about .78

In regard to venous hemodynamics, the higher the intraluminal pressure, the lower the transmural pressure

The external iliac veins always contain valves

The Doppler waveform pattern in the SMA, after eating a high caloric meal, is highly resistive.
