History of Present Illness

History and Chief Complaint. A 54-year-old woman presents to the emergency department at 10pm from a local hotel, where she is vacationing three hours' drive from her home. She complains of atraumatic right leg swelling for the past three days. Yesterday she began to have some pain in the leg and it limited her activity. She otherwise feels well and is in her normal state of good health.

Past medical history is remarkable for obesity, which the patient attributes to hypothyroidism. She has been menopausal for eight years. Specifically, she has never had similar symptoms to those that prompted this presentation, and she has no history of DVT, pulmonary embolism, or clotting disorders. Past surgical history is significant only for liposuction three years ago. Current medications include estrogen, thyroid supplement, and multivitamins. Family history is positive for diabetes and coronary artery disease. Social history is positive for a 40-pack-year cigarette smoking history, but she stopped smoking two years ago. She works as a secretary in a legal office. Review of systems is negative for constitutional symptoms such as fever or appetite changes, for respiratory problems, for chest pain, or for any bleeding problems. She has no known allergies.

Physical examination reveals an obese female who appears somewhat older than her stated age. She is in no apparent distress. Vital signs are blood pressure 152/88, pulse 88, respiration 20/min, and temperature 37.1°C (98.8°F). She is 61 in (155 cm) tall and weighs 176 lb (80 kg). Pulse oximetry reveals a room air oxygen saturation of 96%. The neck examination reveals no jugular venous distention and no carotid bruits. Her heart sounds are normal and there is no murmur, gallop, or rub. Respirations are unlabored and the lungs are clear to auscultation. Her abdomen is obese but soft and nontender. No organomegaly or masses can be appreciated. Pulses are 2+ at the femorals; they cannot be palpated in the popliteal fossa, but are 1-2+ and equal at the feet. The feet are warm and seem well perfused. There is significant obesity of both legs but the patient points out that her right leg appears to be swollen; this is difficult to appreciate on inspection, but measured leg circumference is indeed 3 cm larger on the left than the right at mid-calf, and 2.5 cm larger at the mid-thigh. There is no erythema and no cord is palpable. There are noticeable varicosities on both lower extremities.
