Kara Nguyen experienced pain after undergoing a splenectomy, which is the surgical removal of the spleen. She was 23 years old at the time. Her surgeon, Dr. Jorge Leiva, ordered a CT scan. Dr. Andre Arash Lighvani, a radiologist, interpreted the scan as normal.
She was discharged from the hospital and followed up with Dr. Leiva. About a week later, she was readmitted to the hospital suffering from fever and abdominal pain.
After a second CT scan was completed, Dr. Leiva and another general surgeon, Dr. Ziad Amr, diagnosed a blood clot in her portal vein, which was allegedly apparent on both CT scans. Dr. Amr discharged her five days later without a treatment plan for the vein clot.
