Abstract:
We report 2 successful cases treated with trans-catheter arterial embolization(TAE)for hemorrhagic shock due to pseudoaneurysm rupture at the primary tumor site in advanced colorectal cancer. Case 1: A 73-year-old female underwent Hartmann surgery at another hospital for rectal perforation and peritonitis. Six months later, she had a massive bloody stool and was transferred to our hospital. She was diagnosed with bleeding from advanced rectal cancer that remained following the first surgery. Contrast computed tomography(CT)showed that a branch of the superior rectal artery(SRA)developed an aneurysm at the primary tumor site, and TAE was performed to stop bleeding on hospital day 3. Case 2: A 79-year-old male with type 2 sigmoid colon cancer and simultaneous multiple liver metastases developed copious blood in the stool before primary tumor resection and was transferred to our hospital. Contrast CT showed that a branch of the SRA developed an aneurysm at the primary tumor site, and TAE was immediately performed to stop bleeding.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
