==Anatomy:==
*Continuation of the subclavian artery
*Defined by the lateral border of the first rib to the inferior border of teres major muscle
*Continues as the brachial artery
*Axillary vein runs medial to the artery

==Background:==
Axillary artery thrombosis may occur secondary to multiple mechanisms:
*Thoracic outlet compression from cervical ribs, anomalous fibrous bands, or scalene muscle hypertrophy
*Abduction and external rotation of the upper extremity resulting in compression, contusion, and subsequent thrombosis of the artery by the humeral head [such as in baseball pitchers]
*Distal embolization, such as from an aneurysmal subclavian artery
*The second portion of the artery may be compressed and occluded by the pectoralis minor [“hyperabduction syndrome”]
*Sequela of direct arterial injury [such as penetrating injuries, displaced humeral neck fractures, arterial intimal tears]
*Rarely, anterior shoulder dislocation may lead to thrombosis
*Improper use of crutches may cause axillary artery aneurysm and subsequent thrombosis

==Clinical Features:==
*Symptoms of vascular insufficiency: fatigue of the extremity, pallor, poikilothermia, pain, paraesthesias, pulselessness/diminished pulses (radial, ulnar)
*Blood pressure discrepancy between the upper extremities

==Physical Exam:==
*Examination findings of vascular insufficiency (see above)
*Pulse discrepancy between upper extremities
*Blood pressure discrepancy between upper extremities
*May require doppler to detect pulse
*Potentially, distal ischemic infarcts from thrombus embolization

==Diagnosis/Workup:==
*Labs: Coagulation studies
*Imaging: Duplex scan, Arteriography

==Differential Diagnosis:==
*Arterial compression without thrombosis
*Thrombosis proximal or distal to the axillary artery
*Arterial dissection
*Vasculitides

*Vascular Consult:
*Direct thrombolysis followed by oral anticoagulation
*Surgical exploration may be indicated

==Disposition:==
*Admit

==Complications:==
*Distal ischemia of upper extremity (neurovascular compromise)
*Distal embolization of thrombus
*Compartment syndrome of upper extremity
