A 71-year-old man with multiple myeloma presented with port-induced SVC occlusion ( a ). After multiple passes were made from cranial to caudal with the back end of glide wire (arrow, b ), through-and-through access was obtained. However, the patient subsequently developed hypoxia and hypotension. Contrast injection demonstrated massive extravasation into the right hemithorax ( c ). The patient suffered pulseless electrical activity arrest and died.
