Abstract:

For nursing issues such as atypical symptoms and rapid progression of the condition when the aneurysm ruptured，measures were taken，including closely monitoring the risk of delayed major bleeding and promptly initiating a chain emergency response plan，multi-dimensional management to improve specialized nursing care after portal vein reconstruction，intestinal nutrition support scheme guided by dual-track assessment，balancing bleeding and thrombosis to prevent thrombosis from worsening. After 56 days of meticulous care，the patient recovered and was discharged.

Key words: Pancreaticoduodenectomy, Aneurysm, Gastrointestinal Bleeding, Critical Care Nursing
