To present the imaging findings of the most common vascular compression syndromes, with a review of recent literature.

Vascular compression syndromes are defined as an entity caused by the entrapment of blood vessels (artery or vein) with a rigid or semi-rigid surface in an anatomically confined space. It affects approximately less than 1% of the general population [1]. There is a very large spectrum of syndromes, divided according to whether the involvement is arterial, venous or mixed. Among the most representative syndromes are May-Thurner syndrome, Nutcracker syndrome and thoracic outlet syndrome [1]. Pathophysiology and clinical features of each syndrome depend on the type...

We present a review of the representative imaging findings of the most frequent compressive vascular syndromes with differents methods. May-Thurner syndrome Better known as compression syndrome of iliac vein, is a pathology that is defined as compression of left common iliac vein (LCIV) between lower lumbar spine and right common iliac artery (Fig. 1) [3]. The exact incidence is unknown because the compression of iliac vein is an underdiagnosed anatomical variant and appears asymptomatic in most cases, without requiring treatment [4]. Among the risk factors...

The vascular compression syndromes are generally asymptomatic, but when they present symptoms, they tend to be multiple and non-specific, which delays the diagnosis of these pathologies. The knowledge of the different available imaging methods allows an opportune diagnosis, improving the quality of life of the patient and avoiding the long-term consequences.
