Mesenteric venous thrombosis occurring late after splenectomy.

N Nagasue, K Inokuchi, M Kobayashi

    The British Journal of Surgery
    |November 1, 1977
    PubMed
    Summary

    Splenectomized patients can develop dangerous thrombocytosis and mesenteric venous thrombosis years after surgery, especially with severe anemia. Early heparin treatment for immediate post-splenectomy thrombocytosis and managing late anemia are crucial for prevention.

    Area of Science:

    • Vascular Surgery
    • Hematology
    • Gastroenterology

    Background:

    • Splenectomy can lead to thrombocytosis, an increase in platelet count.
    • Mesenteric venous thrombosis is a serious complication that can occur after splenectomy.

    Observation:

    • Two cases of late-onset mesenteric venous thrombosis (2 years 5 months and 3 years post-splenectomy) are presented.
    • Both patients experienced persistent severe anemia preceding the thrombotic event.
    • Thrombocytosis was noted in one case prior to the thrombosis.

    Findings:

    • Reactive thrombocytosis can occur late after splenectomy, even in the presence of severe anemia.
    • Persistent severe anemia may be a risk factor for late thrombotic complications in splenectomized patients.

    Implications:

    • Immediate post-splenectomy thrombocytosis should be managed with anticoagulants.
    • Preventing persistent severe anemia in splenectomized patients is critical for avoiding late thrombotic events.
    • This highlights the importance of monitoring platelet counts and managing anemia in long-term splenectomized patients.
