Thoracic outlet syndrome is a rare neurovascular disease, usually caused by compression of subclavian vessels and/or brachial plexus by a cervical rib or hypertrophic scalene muscles. When the subclavian artery is compressed, it can cause perfusion deficiency with cyanosis and greater fatigue of the upper limb; if the subclavian vein is compressed, it can cause venous congestion with swelling and pain in the upper limb. When compression affects the brachial plexus, it can cause tingling or paresthesia of the upper limb. It can be mono or bilateral, congenital, or acquired. The diagnosis of vascular alterations is difficult due to the rarity, poor knowledge, and nonspecificity of symptoms. Ultrasound allows to localize and measure the vascular stenosis degree. Failure to diagnose can expose patients to serious health risks. We describe a rare case of venous compression caused by anterior scalene muscle hypertrophy.
胸廓出口综合征是一种罕见的神经血管疾病，通常由颈肋或肥厚的斜角肌压迫锁骨下血管和/或臂丛神经引起。当锁骨下动脉受压时，可导致灌注不足，出现上肢青紫和更易疲劳；若锁骨下静脉受压，可导致静脉淤血，出现上肢肿胀和疼痛。当压迫影响臂丛神经时，可导致上肢刺痛或感觉异常。它可以是单侧或双侧的，先天性的或后天获得的。由于该病罕见、认知不足且症状不具特异性，血管改变的诊断较为困难。超声可用于定位和测量血管狭窄程度。未能确诊可能会使患者面临严重的健康风险。我们描述了一例由前斜角肌肥大引起静脉受压的罕见病例。
