To divide conditions of Vascular compression disorders into Compression of a vascular structure and Compression by a vascular structure or both. To look for the key imaging features of these syndromes at different modalities.

Vascular compression syndromes are clinical entities caused by the entrapment of one or more blood vessels between rigid or semirigid surfaces in a confined anatomic space. Vascular compression disorders is divided into into Compression of a vascular structure and Compression by a vascular structure or both. The most commonly used imaging techniques are noninvasive and include color Doppler ultrasonography (US), computed tomographic (CT) angiography and venography, and magnetic resonance (MR) angiography and venography. However, digital subtraction angiography (DSA) continues to play a major role in...

(A)COMPRESSION OF A VASCULAR STRUCTURE 1)Eagle syndrome- Symptomatic elongation of the styloid process or calcified stylohyoid ligament.The syndrome can be divided into two main subtype Due to compression of cranial nerves(cranial nerves V, VII, IX and X) Due to compression of the carotid artery. 2)Thoracic outlet syndrome- Neurovascular syndrome caused by compression of the subclavian vessels and brachial plexus in the narrow thoracic outlet area. 3)Nutcracker syndrome -Compression of the left renal vein most commonly between the superior mesenteric artery (SMA) and aorta. 4)Median arcuate...

Vascular compression syndromes rare clinical entities that usually affect young. The diagnosis of a syndrome should be based on correlation of clinical and radiologic findings based on Characterization of compression by Identify the offending vessel (artery or vein), Precise point of contact, Single or multiple points of contact and Contact /displacement etc. which help for accurate reporting and diagnosis.
