Abstract:
A patient with paroxysmal nocturnal hemoglobinuria of 14 years duration presented with severe abdominal pain and fever. On admission, his hematocrit had fallen to 19% from his usual level of approximately 30%, and stools were positive for occult blood. Dilated loops of small bowel with air fluid levels were noted on radiographs, and sonography revealed free intraperitoneal fluid. Several sections of gangrenous jejunum and ileum were resected at exploratory laparotomy, and mesenteric venous thromboses were present. This is the second report of pathologically proven intestinal infarction in a patient with paroxysmal nocturnal hemoglobinuria who has survived this abdominal emergency with surgical intervention. Although abdominal pain in patients with paroxysmal nocturnal hemoglobinuria has frequently been attributed to mesenteric venous thromboses, this has rarely been documented either during life or at autopsy.
