New Vein Compression Entities in Patients with Unexplained Leg Swelling

This study provides evidence to broaden the disease profile of venous compression syndromes to other sites such as the hypogastric artery, inguinal ligament, and popliteal fossa. The results support previous research that suggests increased incidence of NTVO exists among patients with unexplained lower extremity edema and pain. In an effort to encourage further exploration, we developed a diagnostic algorithm to support a critical and systematic review of patients with lower extremity edema and pain that may go unexplained using traditional diagnostic measures, including ultrasound, CTA, and MRI alone.
