Abstract:
Pylephlebitis is defined as suppurative thrombophlebitis of the portal venous system. It is a rare condition that can be fatal if left untreated. It is usually caused by polymicrobial bacteria, most commonly Escherichia coli and Streptococcus genus. Klebsiella pneumoniae have been identified but the literature does not suggest a percentage of cases caused by this organism. The presentation includes abdominal pain, signs of sepsis and even septic shock. We present a case of a middle-aged female with K. pneumoniae bacteremia and pylephlebitis, with portal vein thrombosis visualized on an abdominal ultrasound. Although the patient was treated with broad-spectrum antibiotics and anticoagulation, she succumbed to multiorgan failure and septic shock on day two of intensive care.
Insights
Pylephlebitis, a rare but fatal portal vein thrombophlebitis, is often caused by polymicrobial bacteria. This case highlights a fatal outcome from Klebsiella pneumoniae bacteremia and pylephlebitis despite treatment.
Area of Science:
- Medical microbiology
- Vascular medicine
- Infectious diseases
Background:
- Pylephlebitis is suppurative thrombophlebitis of the portal venous system, a rare and potentially fatal condition.
- It is typically caused by polymicrobial bacteria, with Escherichia coli and Streptococcus species being most common.
Observation:
- This report details a case of a middle-aged female patient diagnosed with Klebsiella pneumoniae bacteremia and pylephlebitis.
- Portal vein thrombosis was confirmed via abdominal ultrasound.
Findings:
- Despite treatment with broad-spectrum antibiotics and anticoagulation, the patient experienced multiorgan failure and septic shock.
- The patient succumbed to complications on the second day of intensive care.
Implications:
- This case underscores the severe prognosis of Klebsiella pneumoniae-associated pylephlebitis.
- It highlights the critical need for prompt diagnosis and aggressive management of portal venous system infections.
