Objectives: After studying the article entitled “Duplex Ultrasound Findings of Popliteal Artery Aneurysms With Acute Limb Ischemia,” you will be able to:
Define and document the presence or absence of a popliteal artery aneurysm
Determine appropriate sonographic studies to complement the finding of a popliteal artery aneurysm
Describe the clinical sequelae of untreated symptomatic popliteal artery aneurysms
Of patients with popliteal artery aneurysm, approximately what percentage have bilateral popliteal artery aneurysms? 35% 40% 50% 60%
Of patients with popliteal artery aneurysm, approximately what percentage also have aortic aneurysms? 25% 34% 37% 50%
Of patients with popliteal artery aneurysm, approximately what percentage are male? 90% 85% 80% 75%
The primary clinical concern with a popliteal aneurysm is Rupture Hypotension secondary to exsanguination Extrinsic compression of the popliteal vein causing swelling Distal embolization with limb-threatening ischemia
The imaging modality used for initial evaluation of a suspected popliteal artery aneurysm should be Contrast angiography Computed tomographic angiography Magnetic resonance angiography Duplex sonography
If a symptomatic popliteal artery aneurysm is left untreated, approximately what percentage of patients develop thromboembolic complications? 25% 35% 40% 50%
A popliteal artery aneurysm is defined as a ____ times increase in size compared to a normal proximal vessel segment. 1.5 2.0 2.5 3.0
Compared to duplex sonography, contrast angiography is reported to detect approximately what percentage of popliteal artery aneurysms? 67% 75% 80% 90%
Approximately what percentage of popliteal artery aneurysms become symptomatic?
75%
67%
60%
50%
Important clinical parameters to measure when evaluating a popliteal artery aneurysm with duplex sonography include Location and size Native vessel dimensions Color and spectral Doppler flow patterns All of the above
