Summary
Compression syndromes of the upper limb neurovascular bundle are common, often causing neurological and vascular issues. Surgical resection of the first rib offers an effective treatment for these conditions.
Area of Science:
- Orthopedics
- Vascular Surgery
- Neurology
Background:
- Neurovascular compression syndromes in the upper limb are a recognized clinical entity, though precise incidence remains undetermined.
- Compression can occur at multiple anatomical sites: costo-clavicular space, interscalene triangle, or pectoralis minor insertion.
- These syndromes frequently impact both neurological and vascular structures.
Observation:
- Over 90% of affected individuals experience neurological symptoms, with approximately 10% also exhibiting vascular complications.
- Diagnostic evaluation necessitates thorough clinical assessment and instrumental studies.
- Imaging techniques like arteriography, phlebography, and Doppler ultrasonography are crucial for identifying subclavian artery and vein compression, particularly with arm abduction.
Findings:
- Electromyography (EMG) plays a vital role in differentiating these syndromes from carpal tunnel syndrome, pinpointing the location and severity of nerve compression.
- Vascular imaging confirms compression of the subclavian artery and vein during specific arm movements.
Implications:
- Accurate diagnosis through a combination of clinical and instrumental methods is essential for effective management.
- Surgical intervention, specifically first rib resection via an extrapleural and transaxillary approach (Roos procedure), is considered the optimal treatment strategy.
