Design outcomes

Primary

Measure	Time frame
The main objective of the study is the sonographic assessment of venous congestion syndrome of the legs in bariatric patients; for this purpose, a sonography of the lower extremity is performed immediately pre-bariatric (directly before the planned bariatric surgery) and the following ultrasound criteria are recorded using the B-mode technique or duplex sonography at defined measuring points: - VFC on both sides in supine position: Diameter and flow - AFC flow - VSM on both sides in supine position, 15 cm distal to the crosses: Diameter, flow reversal (Valsalva), alternatively flow reversal only in the VFC - Thickness of cutis and subcutis of lower leg medially on both sides 10 cm above the tip of the inner ankle - Visualization and thickness of lymphatic gaps Lower leg medially on both sides 10 cm above the tip of the medial malleolus - Elastography US on both sides, measuring point as above The sonographic examination is standardized using the GE LoGiQ S7 Expert and a 9.0 MHz transducer.	—

Secondary

Measure	Time frame
1.To document the prevalence of venous stasis-related findings—including chronic venous insufficiency, lipedema, and lymphedema—in the bariatric patient population using sonographic imaging. 2.To evaluate correlations between sonographic findings and clinical/laboratory parameters, aiming to better understand the interplay between vascular and lymphatic alterations and metabolic or hormonal status in this patient group.	—
