A 65-year-old man presents with a 2-week history of abdominal discomfort. Physical examination reveals a pulsatile abdominal mass in the periumbilical region. A CT scan shows a segment of abdominal aorta proximal to the bifurcation that is dilated (5 cm) and calcified. The patient is scheduled for corrective surgery but suffers a massive stroke and expires. The abdominal aorta is examined at autopsy (shown in the image). Which of the following is the most likely underlying cause of this patient's abdominal mass? (A) Angiosarcoma (B) Atherosclerosis (C) Cystic medial necrosis (D) Hypercalcemia (E) Thromboembolism

Answer the following: After applying the tourniquet on the antecubital fossa of a 30-year-old female patient, you were puzzled. There was no sign of the median cubital vein. You then moved to the cephalic vein, selecting a site and cleaning it. After it dried, you inserted the needle using an evacuated tube system. Blood dripped very slowly into the tube; at this rate, you thought the collection would take over 5 minutes, and the sample would likely still be inadequate. You explained this to your patient, removed the needle, and inserted it further up the vein—still almost no flow. You then reapplied the tourniquet, chose a site in the basilic vein and tried again. This time there was no blood—you must have missed the vein. What did you do wrong? What should you do now?
