Persistent truncus arteriosus is a rare congenital cyanotic heart defect characterized by a single ventricular outflow tract. Without surgical intervention, it has a poor prognosis in infancy. Here, we report an adult female patient with uncorrected truncus arteriosus type I, who presented with acute-onset abdominal pain due to torsion of a small bowel gastrointestinal stromal tumor (GIST).
A 41-year-old woman came to our Emergency Department with acute-onset lower abdominal pain for 2 days. Congenital heart disease, truncus arteriosus, had been diagnosed at birth, and there had been no surgical intervention. Abdominal computed tomography revealed a 10×9×12-cm mixed-density mass in the pelvic capacity. Transthoracic echocardiography revealed a 33-mm ventricular septal defect. The ascending aorta originated mainly from the right ventricle, and the pulmonary artery originated from the beginning of the aorta (type I truncus arteriosus, according to Collett and Edwards classification). After a quick and detailed preoperative workup, the patient underwent tumor resection by open surgery with general anesthesia.
This is the first case to report emergency surgery for a patient with uncorrected persistent truncus arteriosus due to torsion of a small bowel GIST. A multidisciplinary team with deep understanding of the disease entity was crucial. By considering the fixed hemodynamic and respiratory physiology, overtreatment and unrealistic goals were avoided. Eventually, the patient was discharged after being hospitalized for 2 weeks.
