McCleery syndrome

Last revised by Frank Gaillard on 20 Apr 2021

McCleery syndrome is a subtype of venous thoracic outlet syndrome with symptoms resulting from compression of the subclavian vein without thrombosis (in contrast to Paget-Schroetter syndrome). 

Patients with McCleery syndrome present with intermittent obstruction of the subclavian vein that results in upper-limb swelling and discolouration 1

McCleery syndrome, like other venous thoracic outlet syndromes, results from compression of the subclavian vein as it exits the chest over the first rib, below the clavicle and between the subclavius tendon and anterior scalene muscle 1

These are discussed in the parent article, venous thoracic outlet syndrome.

To avoid eventual thrombosis, surgical decompression is often recommended 1

The condition was first described by Charles W. McLaughlin Jr. in 1939, but it was not until 1951 that McCleery et al fully described the syndrome 2
