Abstract:
We report a case of patient with Clostridium perfringens septicemia and thrombophlebitis of the portal vein (pylephlebitis), probably secondary to an initially unrecognized gastric ulcer. The extension of the thrombosis from the superior mesenteric vein to the main portal vein on a repeat CT scan and subsequent partial resolution of the thrombus with antibiotic therapy alone, suggested that Clostridium perfringens bacteremia may have enhanced the formation of thrombus. The coexistence of Clostridium perfringens septicemia and pylephlebitis should prompt a search for intra-abdominal processes as the portal of entry of infection.
Insights
Clostridium perfringens septicemia can cause portal vein thrombosis (pylephlebitis), potentially linked to gastric ulcers. Antibiotic treatment alone showed partial thrombus resolution, suggesting bacterial involvement in clot formation.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Vascular Surgery
Background:
- Portal vein thrombosis (pylephlebitis) is a serious condition often associated with intra-abdominal infection or malignancy.
- Clostridium perfringens is a gram-positive bacterium known to cause severe infections, including sepsis.
Observation:
- A patient presented with Clostridium perfringens septicemia and pylephlebitis, likely stemming from an undiagnosed gastric ulcer.
- Imaging revealed thrombosis extending from the superior mesenteric vein to the main portal vein.
Findings:
- Partial resolution of the portal vein thrombus was observed following antibiotic therapy for Clostridium perfringens bacteremia.
- The findings suggest that Clostridium perfringens bacteremia may play a role in enhancing thrombus formation in the portal vein.
Implications:
- The concurrent presence of Clostridium perfringens septicemia and pylephlebitis necessitates a thorough investigation for underlying intra-abdominal infectious sources.
- Early recognition and treatment of Clostridium perfringens infections are crucial in managing complex cases of portal vein thrombosis.

Hepatic Portal System
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
