Neurovascular Compression After the Latarjet Procedure

Abstract

The Latarjet procedure is an established and effective option for the treatment of recurrent anterior shoulder instability. Symptomatic compression of the vasculature around the shoulder and adjacent brachial plexus is uncommon and may be difficult to diagnose and treat. The purpose of this report is to describe a patient with neurovascular compression of the axillary artery and brachial plexus after an open Latarjet procedure. This is the first known report of documented combined vascular and neurologic thoracic outlet syndrome after a Latarjet procedure. Evaluation of this suspected problem requires a detailed clinical examination and a dynamic angiogram to verify which neurovascular structures are compressed. Treatment includes decompression of the brachial plexus and axillary vasculature by releasing tethering scar tissue or the remaining pectoralis minor that is creating a constricting sling effect. An arthroscopic approach provides for a careful and specific decompression. Additionally, the authors provide a review of the literature for neurologic complications and management for these complications.
