Abstract
We report two patients with ulcerative colitis (UC) discovered to have deep vein thrombus (DVT) by preoperative CT scan, and implanted inferior vena cava (IVC) filter. Patient 1, a 33-year-old woman, was diagnosed with UC four years earlier, followed and treated. She was admitted to our hospital because of melena and lower abdominal pain. Although she was treated by an internist, her symptoms were not well controlled. Consequently, she was referred to us for operation. Preoperative CT scan revealed DVT from right internal iliac vein to right common iliac vein, and lung scintigraphy revealed a pulmonary embolism (PE). An IVC filter was implanted before operation. Patient 2, a 59-year-old woman, was diagnosed with UC seven years earlier, followed and treated. She was admitted to another hospital because of diarrhea and fever. Then she was referred to our hospital due to steroid resistance. She experienced abdominal pain after admission to our hospital, and CT scan revealed free air and DVT from the right common iliac vein to the IVC. After the emergency operation, an IVC filter was implanted. We should pay attention to DVT and PE for patients with UC, especially in the perioperative period.
