How does Pylephlebitis affect the portal vein?
Pylephlebitis begins with thrombophlebitis of small veins draining an area of infection. Extension of the thrombophlebitis into larger veins leads to septic thrombophlebitis of the portal vein, which can extend further to involve the mesenteric veins [ 3 ]. In a review of case reports, the superior mesenteric vein was involved in 42 percent [ 4 ].
