    This study presents intestinal vascular malformations (VMs) in eleven patients, with nine experiencing gastrointestinal hemorrhage. A potential fourth type of VM, secondary to other intestinal diseases, is proposed.

    Area of Science:

    • Gastroenterology
    • Vascular Surgery
    • Surgical Pathology

    Background:

    • Intestinal vascular malformations (VMs) can cause significant gastrointestinal bleeding.
    • Previous classifications of VMs may not encompass all presentations.

    Purpose of the Study:

    • To characterize intestinal vascular malformations (VMs) in a patient cohort.
    • To identify potential new classifications or associations of VMs.
    • To evaluate diagnostic and localization techniques for intestinal VMs.

    Main Methods:

    • Retrospective review of eleven patients diagnosed with intestinal VMs via angiography.
    • Surgical resection and histological examination of affected intestinal segments.
    • Intraoperative localization of a VM using Doppler ultrasonic flow detector.

    Main Results:

    • Nine of eleven patients presented with gastrointestinal hemorrhage and underwent successful resection.
    • Histological examination revealed diverse findings, including leiomyoma vasculature, idiopathic VMs, and inflammatory conditions like Crohn's disease and ischemic colitis.
    • A novel association of VMs with other intestinal diseases was observed in four cases.
    • Doppler ultrasound accurately localized a duodenal VM, aiding in targeted resection.

    Conclusions:

    • A fourth type of intestinal vascular malformation, potentially secondary to other intestinal diseases, is proposed.
    • Doppler ultrasound is a valuable tool for intraoperative localization of intestinal VMs, optimizing surgical resection.
    • Further investigation into the etiology and classification of intestinal VMs is warranted.
