For clinical examination of the lower limbs for chronic venous disease, we recommend

1

A

 

inspection (telangiectasia, varicosity, edema, skin discoloration, corona

 

 

 

phlebectatica, lipodermatosclerosis, ulcer), palpation (cord, varicosity, tenderness,

 

 

 

induration, reflux, pulses, thrill, groin or abdominal masses) auscultation (bruit),

 

 

 

and examination of ankle mobility. Patients should be asked for symptoms of

 

 

 

chronic venous disease, which may include tingling, aching, burning, pain, muscle

 

 

 

cramps, swelling, sensations of throbbing or heaviness, itching skin, restless legs, leg

 

 

 

tiredness, and fatigue.

2.1

We recommend that in patients with chronic venous disease, a complete history and

1

A

 

detailed physical examination are complemented by duplex scanning of the deep

 

 

 

and superficial veins. The test is safe, noninvasive, cost-effective, and reliable.

 

 

2.2

We recommend that the four components of a complete duplex scanning

1

A

 

examination for chronic venous disease should be visualization, compressibility,

 

 

 

venous flow, including measurement of duration of reflux, and augmentation.

 

 

2.3

We recommend that reflux to confirm valvular incompetence in the upright

1

A

 

position of the patients be elicited in one of two ways: either with increased intra-

 

 

 

abdominal pressure using a Valsalva maneuver to assess the common femoral vein

 

 

 

and the saphenofemoral junction, or for the more distal veins, use of manual or

 

 

 

cuff compression and release of the limb distal to the point of examination.

 

 

2.4

We recommend a cutoff value of 1 second for abnormally reversed flow (reflux) in

1

B

 

the femoral and popliteal veins and of 500 ms for the great saphenous vein, the

 

 

 

small saphenous vein, the tibial, deep femoral, and the perforating veins.

2.5

We recommend that in patients with chronic venous insufficiency, duplex scanning

 

of the perforating veins is performed selectively. We recommend that the

 

 

definition of “pathologic” perforating veins includes those with an outward flow of duration of 500 ms, with a diameter of 3.5 mm and a location beneath healed or open venous ulcers (CEAP class C5-C6).

to identify pelvic venous obstruction or iliac vein stenosis in patients with lower limb varicosity when a proximal obstruction or iliac vein compression (May-Thurner syndrome) is suspected.101 They are suitable to establish left renal vein compression (nutcracker syndrome),102 gonadal vein incompetence, and pelvic venous congestion syndrome. MR imaging with gadolinium is especially useful in evaluating patients with vascular malformations, including those with congenital varicose veins.

Intravascular ultrasonography. Intravascular ultrasonography (IVUS) has been used successfully to evaluate iliac vein compression or obstruction and to monitor patients after venous stenting.101 For patients with varicose

veins, IVUS should be used selectively in those with suspected or confirmed iliac vein obstruction. IVUS is important in assessing the morphology of the vessel wall, identifying lesions such as trabeculations, frozen valves, mural thickness, and external compression that are not seen with conventional contrast venography, and it provides measurements in assessing the degree of stenosis. In addition, IVUS confirms the position of the stent in the venous segment and the resolution of the stenosis.101

Laboratory evaluation

Patients with varicose veins are usually operated on under local or tumescent anesthesia, and specific laboratory
