Abstract:
A 71 year old man was diagnosed to have enlargement of abdominal aortic aneurysm due to type 2 endoleak two years after endovascular aneurysm repair (EVAR). 3D-CT demonstrated a type 2 endoleak that originated from the superior mesenteric artery that fed the inferior mesenteric artery and the right iliolumbar artery that flowed into the 4th lumbar artery. Transarterial embolization was performed by means of N-butyl-2-cyanoacrylate (NBCA). After the treatment, he suffered ischemic colitis that extended from the sigmoid colon to the descending colon. Conservative treatment was mainly performed, and clinical improvement was observed over time. He was discharged after 73 postoperative days.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
