Vascular Key Terms Abnormal

Placed in IVC to prevent the ascension of thrombus into the lungs

Location is determined by ultrasound inferior to renal vein, can detect complications: thrombosis around the filter or perforation around the filter or through IVC wall that may be associated with retroperitoneal hematoma.

Dilation of all three layers of the aorta, most aortic aneurisms are distal, don’t involve renal arteries

Spindle-shaped dilatation

Localized spherical outpouching of the vessel wall

Injury to the vessel wall where blood extravasates from vessel, the blood surrounding the vessel is retained and walled off by the surrounding tissues

True aneurisms

Commonly found in groin, resulting from catheters to common femoral artery, during angiographic procedures.

Result of dissection of the intima away from the aortic wall, usually stat in the thoracic aorta

Ascending thoracic aorta

Starts in origin of the left subclavian artery

Is seen as a septations dividing the aorta into a true lumen and a false lumen

Dense, fibrosis tissue proliferation that is confined to the paravertebral and central abdominal region at the fourth or fifth lumbar vertebra, overlying the aortic bifurcation

Smooth-marinated, hypoechoic soft-tissue mass encasing the aorta and IVC

Layered or mantle appearance around vessels of the abdomen

Visualized anterior and posterior to vessels of the abdomen, creating sandwich sign

1.5 increase of normal diameter

• Disease of arterial vessels
• Thickening, hardening, and loss of elasticity of arterial walls

Irregularity of aortic wall because of plaque formation

Thrombosis of the hepatic veins

Periportal collateral channels in patients with chronic portal vein obstruction

Weakening of the arterial wall

Circumferential enlargement of a vessel with tapering at both ends

Hereditary disorder of connective tissue, bones, muscles, ligaments and skeletal structures

Most commonly results from intrinsic liver disease, also arises from obstruction of the portal vein, hepatic vein, IVC, or prolonged congestive heart failure. Many cause flow reversal to the liver, thrombosis of portal vein system, or cavernous transformation of the portal vein

Pulsatile hematoma that results from leakage of blood into soft tissues abutting the punctured artery with fibrous encapsulation and failure of vessel wall to heal

Localized dilation of the vessel

Increased turbulence is seen within the spectral tracing that indicates flow disturbance

Transjugular intrahepatic portosystemic shunt

Outer layer of the vascular system, consists of vasa vasorum

Middle layer of the vascular system, arteries have thicker tunica media than veins

Inner layer of the vascular system
