Unilateral left leg edema: a variation of the May-Thurner syndrome
Cardiovascular and Interventional Radiology
|January 1, 1987
Insights
A patient experienced left leg swelling due to a tortuous left common iliac artery compressing the left common iliac vein. This vascular compression caused significant obstruction, leading to edema.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Vascular Medicine
Background:
- Iliac vein compression can lead to deep vein thrombosis and post-thrombotic syndrome.
- Arterial compression of venous structures is a recognized, though less common, cause of venous obstruction.
Abstract:
A single patient with left leg edema was examined with venography and computed tomography. A tortuous left common iliac artery was found to be compressing the left common iliac vein, causing near total obstruction of the left iliac vein. Hemodynamic pressure measurements confirmed the significance of the obstruction.
