Mesenteric Arcade: Celiac And Sma

  • Sites of Bleeding s/p Whipple’s Procedure: Therapy
    - Embolism with coils, glue or absorbable gelatin sponge
    - Coils
    - Stent grafting
    - Surgery
  • Sites of Bleeding s/p Whipple's Procedure
    - Gastroduodenal stump
    - Common and proper hepatic artery erosions
    - Celiac axis erosions
    - Splenic artery erosions
    - Inferior pancreatoduodenal artery aneurysm
    - Arc of Buhler aneurysm and pseudoaneurysm (mesenteric collateral vessel that originates from common hepatic artery proximal to GDA)
  • Hemorrhagic Complications After Whipple Surgery: Facts

    Early hemorrhage (with 24 hours) is due to GDA stump insufficiency due to technical failure

    Late hemorrhage (after 24 hours) is caused by
    - Ulcer
    - Vascular erosion from pancreatic leak
    - Fistula
    - Pseudoaneurysm
    - Anastomotic dehiscence
  • "Hemorrhagic complications occur in fewer than 10% of patients after Whipple pancreatoduodenectomy but account for as many as 38% of deaths. Bleeding typically occurs from the stump of the gastroduodenal artery, but other sites of bleeding are increasingly recognized."
