Emphasis on Early Identification of Risk Factors to Curtail High Mortality Involved With Ischemic Colitis (IC) After Abdominal Aortic Aneurysm (AAA) Repair.

Ischemic colitis (IC) is one of the most feared complications after abdominal aortic aneurysm (AAA) repair. Though the complication is seen in only a handful of total repairs, the mortality rates after IC is very high. Due to infrequent presentation, attending doctors may overlook this possibility leading to a delay in diagnosis. Open repair and endovascular aneurysm repair (EVAR) are the two most common methods used for repairing aneurysms and both of these procedures have their implications in the development of IC. While the incidence of IC was greater after open repair, it also harbored more patients with ruptured aneurysms, emergency repairs, and patients in shock. Similarly, a significant proportion of patients having ruptured aneurysms developed IC. Controlling minor variables like acidosis, hypothermia, hypovolemia, and clamp time duration can play a cumulative role in diminishing this hazardous complication. Medical advancements and minimally invasive technologies have improved the quality of care and operation success considerably, but researchers have not identified a statistically significant association in the prevention of postoperative IC. Therefore, early diagnosis and prompt management become crucial in reducing mortality rates. This can be achieved by being aware of impending signs and symptoms especially in patients with risk factors and being proactive in medical management.
