Let Science Lead the Way

35 yo mother of three marries a strict disciplinarian who does not believe in science. Her husband has joined various groups in the past, each of which eschew all forms of medical treatment. He has enjoyed excellent health, eats mostly a healthy diet, and trains regularly on overnight weekend jaunts with buddies. The mother of three hopes that in time her health too will improve. Currently, she is constantly tired, and worries that she is again slipping into depressive disorder. But, her husbands insists on no doctor visits!  On one of the weekends that her husband is away, the wife visits a nearby clinic where the doctor finds a significant lump in her breast. She reveals that she knows she is a carrier of BRCA1 and BRACA2. She also reports not having her period for the past three months, at which time her physician performs a pelvic exam and also determines the presence of an ovarian mass. While getting dressed after the exam, the wife begins to feel left arm pain, bulging arm veins, and cyanosis of the skin in the arm. The physician suspects she is experiencing a vascular incident of her upper limb and sends her to the ED. She is immediately prepped for surgery after further tests reveal there is a left subclavian vein thrombosis. To gain proximal control of a bleeding left subclavian vein, at which location should one surgically approach the patient, and where will the thrombus be found in the labeled structures?
