Background
There are many vascular compression syndromes and in this paper we will highlight some of them.
These disorders are divided into two groups.
The first category includes cases where a vessel is compressed by another structure such as Eagle syndrome,
nutcracker syndrome,
posterior nutcracker syndrome,
median arcuate ligament syndrome etc.
On the other hand the second category involves cases where a vascular structure (vein or artery) compresses other adjacent structures,
including ovarian vein syndrome,
dysphagia lusoria,
SMA syndrome etc.
Chronic entrapment in these entities may give rise to arterial ischemia and embolism,
venous stasis and thrombosis and hematuria in young,
otherwise healthy patients.
Anatomical abnormalities and repetitive microtrauma less often are considered as contributing factors.
Digital subtraction angiography (DSA) is the gold standard among imaging test while CT angiography (CTA) is an alternative non-invasive imaging modality.
