Background
Vascular compression syndromes pose a distinct challenge in their diagnosis as they often present with vague and/or relapsing symptoms. These can be subdivided into pathologies in which vessels are being compressed by or are compressing adjacent anatomic structures. Early diagnosis can ensure patients receive care in the timeliest manner. Definitive treatment varies where surgical and endovascular approaches can be used depending on the etiology.

Educational Goals / Teaching Points
This exhibit aims to outline the most common vascular compression syndromes and associated complications; provide a case-based diagnostic imaging review; discuss relevant anatomical variants; differentiate between etiologies with viable endovascular treatment versus surgical options and evaluate reported efficacy; and review endovascular treatment techniques.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit is a multimodality imaging review of vascular compression syndromes and associated complications. These include: nutcracker syndrome, May-Thurner syndrome, superior mesenteric artery syndrome, median arcuate ligament syndrome, Paget-Schroetter syndrome, and popliteal artery entrapment syndrome. Additional discussion of pathology, clinical presentation, and treatment options is presented. We also include a fluoroscopic imaging review of endovascular treatment options including thrombolysis, balloon angioplasty, and stenting.

Conclusion
Vascular compression syndromes consist of a wide array of pathologies with variable clinical presentations, making diagnosis difficult. Understanding clinical and radiological signs can allow for early detection of these disorders, which can pave the way for appropriate endovascular treatment when indicated.
