Benefits of Laparoscopic Surgery for Bleeding Events in Patients with Implantable Left Ventricular Assist Devices during Antithrombotic Therapy

Hemorrhagic ovarian cysts (HOCs), a common gynecological disease causing intraabdominal bleeding, can be life threatening in patients undergoing antithrombotic therapy, especially those with left ventricular assist device (LVAD) implantation under strong antithrombotic therapy. We encountered three postLVAD implantation cases with intraabdominal bleeding due to suspected HOCs, which required surgery for hemostasis. Such patients are not only at a higher risk of bleeding but also have restrictions in available surgical incision sites to avoid damaging the LVAD driveline located underneath the abdominal wall. Laparoscopic surgery, which can be performed through minute incisions with flexible site selection, may benefit intraabdominal hemorrhage patients with LVADs.
