Imagine having rectal bleeding that just won't stop, and doctors struggle to find the cause. That's what happened to a 61-year-old man. The problem turned out to be a rare, abnormal connection between an artery and a vein near his rectum — a condition called a superior rectal arteriovenous fistula. This connection can cause a type of rectal inflammation called ischemic proctitis.
Doctors used a special imaging test called angiography to finally see the hidden blood vessel problem. They first tried to stop the bleeding with a scope and then blocked the abnormal vessels with a procedure called embolization. But the man's rectum developed significant scarring and narrowing, a condition called rectal stenosis.
Because of this scarring, he eventually needed a proctectomy — surgical removal of his rectum. The report notes that diagnosing this condition was quite challenging, which means other people might face similar diagnostic delays. This is just one person's story, so we don't know how common this is or what the best treatment path might be for others. It serves as a detailed record of a complex medical journey, not a guide for treatment.
