The authors note several difficulties in establishing the diagnosis of iliac vein compression syndrome (May-Thurner syndrome), including all of the following except? a. Anatomic compression alone is insufficient for diagnosing iliac vein compression syndrome, as com- pression of over 50% is common in asymptomatic patients. b. While ultrasound (including duplex and color flow Doppler) is commonly used to evaluate patients with suspected deep venous thrombosis, it may be limited in its ability to evaluate the proximal left common iliac vein. c. Identification of endothelial “spurs” on contrast venography may be difficult to distinguish from changes caused by deep venous thrombosis. d. Intravascular ultrasound has not been shown reliable in detecting endoluminal venous pathology associated with iliac vein compression syndrome. 2. Which of the following best describes the design of this study? a. Retrospective, case-control study. b. Randomized prospective comparative study. c. Retrospective cohort study. d. Non-randomized prospective cohort study. 3. For inclusion in this study as a patient with iliac vein compression syndrome, all of the following criteria had to be met except? a. Performance of a contrast-enhanced CT scan of the abdomen and pelvis within 48 hours before any endovascular intervention. b. Stenosis of the left common iliac vein due to compression with development of venous collaterals. c. Clinical evidence of acute deep venous thrombosis. d. Proximal (iliofemoral) left lower extremity deep venous thrombosis. 4. Which of the following results was not obtained in this study? a. No patient in the control group showed over 70% compression of the left common iliac vein. b. No patient with iliac vein compression syndrome had less than 50% compression of the left common iliac vein. c. Despite considerable overlap in the degree of compression for individual patients, the mean degree of compression for patients with iliac vein compression was significantly higher than that of controls. d. More than half of the patients with iliac vein compression syndrome had 70% or greater compression of the left common iliac vein. Oguzkurt et al • 371 Volume 19 Number 3

pression of over 50% is common in asymptomatic patients.b. While ultrasound (including duplex and color flow Doppler) is commonly used to evaluate patients with
suspected deep venous thrombosis, it may be limited in its ability to evaluate the proximal left commoniliac vein.
c. Identification of endothelial “spurs” on contrast venography may be difficult to distinguish from changescaused by deep venous thrombosis.

4. Which of the following results was not obtained in this study?a. No patient in the control group showed over 70% compression of the left common iliac vein.b. No patient with iliac vein compression syndrome had less than 50% compression of the left common
iliac vein.c. Despite considerable overlap in the degree of compression for individual patients, the mean degree of
compression for patients with iliac vein compression was significantly higher than that of controls.d. More than half of the patients with iliac vein compression syndrome had 70% or greater compression
of the left common iliac vein.
