Comparison of Intravascular Ultrasound With Venography in the Diagnosis and Treatment of Iliac Vein Compression Syndrome

Comparison of Intravascular Ultrasound With Venography in the Diagnosis and Treatment of Iliac Vein Compression Syndrome

The aim of this study is to compare intravascular ultrasound with venography in the diagnosis and treatment of iliac vein compression syndrome.

Inclusion Criteria:

• Age: 18 to 90 years
• Willing to participate in and sign the informed consent
• Patients with suspicious iliac vein stenosis or compression presented by preoperative magnetic resonance venography (MRV)
• Patent common femoral vein and/or femoral vein of the study leg
• Undergoing iliofemoral venography with the intend to treat potential iliac vein compression syndrome

Exclusion Criteria:

• Not providing informed consent
• Venous compression caused by pelvic tumors or fibroid uterus
• Previous stent implantation or venovenous bypass surgery of the study leg
• Known metal allergy precluding the possibility of stent implantation
• Known iodine allergy or severe renal insufficient function which are unsuitable for venography
• Pregnant or planning to be pregnant recently
• Acute deep vein thrombosis or tumor thrombus involving the study leg
• Know history of thrombophilia (e.g. protein C or S deficiency, anti-thrombin III deficiency, etc )
• Any concurrent disease, for example, heart failure, might make the patients unsuitable for surgery
