    Summary
    This summary is machine-generated.

    This report details the first US cases of portal vein aneurysm, a rare vascular condition. These aneurysms were identified using ultrasound and angiography in patients with fever and gastrointestinal bleeding.

    Area of Science:

    • Vascular Surgery
    • Radiology
    • Gastroenterology

    Background:

    • Portal vein aneurysm (PVA) is a rare vascular anomaly with limited reporting in global literature.
    • Previous case reports highlight the rarity and diagnostic challenges of PVA.
    • Understanding PVA's presentation and etiology is crucial for accurate diagnosis and management.

    Observation:

    • The study presents the first reported cases of PVA in the United States.
    • Initial detection was via ultrasound in one patient during fever evaluation, with confirmation by angiography.
    • Two additional cases were discovered during angiographic investigation for gastrointestinal bleeding.

    Findings:

    • PVAs were identified at different locations within the portal venous system: one centrally and two distally.

    Related Experiment Videos

  • Ultrasound and angiography are effective imaging modalities for diagnosing PVA.
  • The findings underscore the varied clinical presentations and locations of PVAs.

    • Implications:

    • This report expands the geographic and clinical awareness of PVA in the US.
    • Further research into the etiology and optimal management strategies for PVA is warranted.
    • Enhanced radiologic surveillance may be necessary for patients with unexplained gastrointestinal bleeding or specific risk factors.
