Pylephlebitis usually occurs due to secondary infection in the region drained into the portal system. We report a case of pylephlebitis caused by acute appendicitis. The patient was transferred from a private clinic 1 wk after appendectomy with the chief complaints of high fever and abdominal pain. He was diagnosed with pylephlebitis of the portal vein and superior mesenteric vein by CT-scan. The patient was treated with antibiotics and anticoagulation therapy, and discharged on the 25th day and follow-up CT scan showed a cavernous transformation of portal thrombosis.展开更多

It is traditionally regarded to be an ominous finding of impending death, with highest mortality reported in patients with underlying bowel ischemia. Today, computed tomography has demonstrated a wider range of clinical conditions associated with PVG, some of which are ‘benign’ and do not necessarily require surgery, unless when there are signs of intraabdominal catastrophe or systemic toxicity. One of these ‘benign’ conditions is Crohn’s disease. The present report describes a 19-year-old Chinese boy with Crohn’s pancolitis who presented with septic shock associated with PVG and portal vein thrombosis, and was successfully managed surgically. To our knowledge, this is the fi rst report of PVG and portal vein thrombosis associated with Crohn’s disease in a Chinese patient. In addition, we have also reviewed the reports of another 18 Crohn’s patients with PVG previously described in the English literature. Specifi c predisposing factors for PVG were identified in 8 patients, including barium enema, colonoscopy, blunt abdominal trauma, and enterovenous f istula. The patients who developed PVG following barium enema and blunt trauma were all asymptomatic and no specifi c treatment was necessary. Eleven patients (58%) who presented with signs of intraabdominal catastrophe or systemic toxicity required either immediate or eventual surgery. The overall mortality rate among the 19 patients was only 11%. The present literature review has shown that the f inding of PVG associated with Crohn’ s disease does not always mandate surgical intervention. It is the clinical features and the related complications that ultimately determine the treatment approaches. The overall outcome of PVG associated with Crohn’s disease has been favourable.展开更多
