Q80) A 55 y/o male with history of lung cancer recently had a porta cath placed in the SVC. However, one week later he presents to your office with increasing swelling of this face, neck and upper extremities and increasing jugulovenos distension. You diagnose SVC syndrome and your suspicion is confirmed by an SVC venogram. You send the patient to interventional radiologist for SVC dilatation. In the radiology OR patient suddenly becomes unresponsive and hypotensive. His heart rate was 140 and B.P 78/40. He responds well to IV fluids but tachycardia persists. He is then transferred to ICU.
