Surgery for pancreatic cancer tumor encircling blood vessels is very complicated, and it is easy to damage blood vessels during surgery causing bleeding or even hemorrhagic shock. Pancreatic cancer tumor may invade or encircle blood vessels to get nutrients and thus proliferate rapidly. In the process of surgical resection of the tumor, it is easy to damage the blood vessels due to improper operation, and the complete resection of the tumor may also be affected due to the interference of the blood vessels, which is a complicated and risky surgery. It is recommended to undergo a comprehensive examination and treatment under the doctor’s comprehensive assessment. Neoadjuvant radiotherapy can also be used to shrink the tumor lesions before surgery, thus facilitating surgical resection. If pancreatic cancer is suspected or diagnosed, it is recommended to go to a regular hospital for comprehensive assessment of the condition and follow the doctor’s instructions for treatment to avoid delay.
