    A patient arrives at the emergency department with neck, face and arm edema, distended arm and neck veins, as well as dilated and tortuous veins on their upper chest and back. You suspect that there is a supra-azygous SVC obstruction. In the lateral thoracic pathway how does the blood make its way back to the heart?
    • A. 

      Lateral thoracic --> Intercostals --> Accessory hemiazygos or hemiazygos --> Azygos.

    • B.

    A 65 year-old male presents to the clinic with an acute onset of dyspnea, chest discomfort, and general malaise. On physical examination, the patient presents with enlarged neck veins and edema in the facial and brachial regions. Radiological imaging shows an enlarged thymic shadow. Biopsy results confirm the surgeon's suspected diagnosis and the patient is prepped for surgery. During surgery, the resident surgeon notices a collateral circulation.

    • B. 

      Subclavian Vein

    • C. 

      Gonadal Vein

    • D. 

      Azygos Vein

    • E. 

      Internal Thoracic Artery
