De Garengeot Hernia Diagnosed with Point-of-care Ultrasound.

De Garengeot hernias, defined as a femoral hernia containing the appendix, are rare. It is even uncommon to have an incarcerated de Garengeot hernia with associated acute appendicitis. We report a case of a 76-year-old female presenting to the emergency department for a right lower quadrant abdominal mass for four days. Physical exam was consistent with an incarcerated hernia. A point-of-care ultrasound revealed a non-compressible, blind-ended loop of bowel within the hernia sac, concerning for acute appendicitis within the mass. Computed tomography of the abdomen and pelvis confirmed the diagnosis of acute appendicitis within a femoral hernia.

Uterine Artery Pseudoaneurysm: A Life-Threatening Cause of Vaginal Bleeding in the Emergency Department.

BACKGROUND: Vaginal bleeding is a common presenting complaint in the emergency department (ED); life-threatening hemorrhage is rare. Uterine artery pseudoaneurysm (UAP) is an uncommon but potentially life-threatening cause of vaginal bleeding that is most likely to present primarily to EDs, given its delayed postpartum or postoperative presentation. CASE REPORT: A 25-year-old female gravida two, para one, who was 19 days post dilation and evacuation for an elective termination of a pregnancy at 20 weeks, presented to the ED with profuse vaginal bleeding. She was hypotensive and tachycardic at presentation, requiring resuscitation with 0.9% normal saline and transfusions of packed red blood cells. Transvaginal ultrasound completed in the ED demonstrated a pulsatile mass in the cervix with internal "ying-yang" flow on Doppler images, suggestive of a uterine artery pseudoaneurysm within the cervix. The patient underwent emergent uterine artery embolization with resolution of bleeding and improvement in her hemodynamic status. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: UAP is an uncommon cause of vaginal bleeding, but UAP rupture can be life-threatening. UAP is an important differential diagnosis for vaginal bleeding, particularly in the postpartum or postoperative setting. Delaying diagnosis may worsen bleeding in the setting of a ruptured UAP if treatment is pursued for alternative diagnosis; for example, treating retained products of conception with a dilation and curettage. Being aware of UAP and how to diagnose it will allow early proper treatment and more favorable patient outcomes.
