Vascular Injury Following Pyloric Dilation: Unusual Cause of Ischemic Colitis
نویسندگان
چکیده
A 57-year-old female with intrahepatic cholangiocarcinoma underwent hepatic trisegmentectomy and chemoradiation. Her course was complicated by recurrent episodes of radiation-induced gastric outlet obstruction requiring balloon dilations. She presented with right lower quadrant pain after routine upper endoscopy with pyloric dilation. A computed tomography (CT) showed isolated right-sided ischemic colitis with vascular contrast in the mesentery. Repeat CT after conservative management revealed near resolution of the ischemic changes. Perforation at the level of the pylorus is a complication of endoscopic pyloric dilation but vascular injury has never been described.

متن کاملIschemic colitis complicating major vascular surgery.
Ischemic colitis is a well-described complication of major vascular surgery, especially following open abdominal aortic aneurysm repair and endovascular aneurysm repair, but also with aortoiliac surgery, aortic dissection, and thoracic aneurysm repair. Following its onset, mortality remains high, highlighting the need for rapidly identifying the onset of symptoms and, perhaps more importantly, ...
متن کاملIschemic colitis associated with herbal product use in a young woman.
Ischemic colitis is most often thought of as a condition that occurs in elderly patients, usually as a result of some form of vascular disease. Ischemic colitis, however, also occurs in younger, otherwise healthy adults. When it occurs in this population, it is usually self-limited and is commonly called transient ischemic colitis. Some publications associate this transient form with estrogen o...
متن کاملA case of a rectal stricture related to ischemic proctitis following rupture of an aortic aneurysm
Background and study aims Ischemic proctitis is a rare disease and comprises 2 % to 5 % of cases of ischemic colitis, because the rectum has abundant blood supply and rich collaterals. Herein, we report a case of a 73-year-old male patient with a pronounced rectal stricture caused by ischemic proctitis resulting from an abdominal aortic rupture and treated by endoscopic balloon dilation therap...
