Insights
This case study highlights a challenging severe colonic diverticular bleeding case. Precise CT localization after superior mesenteric arteriography enabled successful superselective arterial embolization.
Area of Science:
- Gastroenterology
- Interventional Radiology
Background:
- Severe colonic diverticular bleeding can be life-threatening and difficult to manage.
- Recurrent bleeding necessitates effective diagnostic and therapeutic strategies.
Observation:
- A 50-year-old male presented with relapsing severe colonic diverticular bleeding requiring 14 units of blood transfusion.
- Initial diagnostic modalities including CT, colonoscopy, and angiography failed to identify the bleeding source.
Findings:
- Superselective arterial embolization was successfully performed.
- Precise localization of the bleeding site was achieved using CT immediately following superior mesenteric arteriography.
Implications:
- This case demonstrates the utility of advanced imaging techniques for managing obscure gastrointestinal bleeding.
- Accurate localization is crucial for successful endovascular intervention in severe diverticular hemorrhage.
Abstract:
We report a case of 50-year-old man with relapsing severe colonic diverticular bleeding. The patient required total blood transfusion of 14 units, despite fasting for bowel rest. Repeated CT, colonoscopy, and angiography could not determine the accurate bleeding site. Superselective arterial embolization could be finally achieved by precise localization on CT immediately after superior mesenteric arteriography.
