Cecal necrosis after open-heart operation.

W C Hargrove, E F Rosato, R E Hicks

    The Annals of Thoracic Surgery
    |January 1, 1978
    PubMed
    Summary

    Cardiopulmonary bypass can cause nonocclusive intestinal infarction, specifically affecting the cecum. Early diagnosis and surgical exploration are crucial for patients with abdominal complaints after open-heart surgery.

    Area of Science:

    • Cardiology
    • Gastroenterology
    • Surgical Complications

    Background:

    • Cardiopulmonary bypass (CPB) is a complex procedure often associated with significant patient morbidity.
    • Patients undergoing CPB often have pre-existing cardiovascular conditions that increase their risk profile.
    • Nonocclusive intestinal infarction is a rare but life-threatening complication following major surgery.

    Observation:

    • This report details two cases of isolated transmural ischemic necrosis of the cecum in patients post-cardiopulmonary bypass.
    • These patients presented with nonspecific abdominal complaints in the postoperative period.
    • The ischemic necrosis was not attributed to a specific arterial occlusion.

    Findings:

    • Cardiopulmonary bypass appears to be an independent risk factor for nonocclusive intestinal infarction, superimposed on existing cardiovascular disease.
    • The cecum was the primary site of ischemic injury in both reported cases.
    • Diagnostic challenges include distinguishing this complication from other postoperative abdominal issues.

    Implications:

    • Postoperative abdominal symptoms in patients after open-heart surgery warrant a high index of suspicion for intestinal infarction.
    • A thorough diagnostic workup, including advanced imaging like contrast studies and angiography, is essential.
    • Early surgical intervention, including abdominal exploration, may be critical for improving outcomes in this high-risk patient group.
