Per catheter control of haemorrhage from the superior and inferior mesenteric arteries
Insights
Catheter-directed therapies effectively control gastrointestinal bleeding. Vasopressin infusion and embolization are key techniques, though complications like cecal infarction can occur, necessitating careful consideration of bowel vascular anatomy.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Vascular Surgery
Background:
- Hemorrhage from the large and small bowel presents significant clinical challenges.
- Catheter-directed therapies offer minimally invasive treatment options for gastrointestinal bleeding.
Observation:
- This study reviews 11 cases of percutaneous catheter control of bowel hemorrhage.
- Techniques included vasopressin infusion and gelfoam embolization.
- Complications such as cecal infarction were noted.
Findings:
- Vasopressin infusion was successful in some cases, while embolization achieved hemostasis in others, including cases where vasopressin failed.
- Embolization of the ileocolic artery led to a cecal infarct in one instance.
- Significant differences in the vascular supply between the large and small bowel impact embolization strategies.
Implications:
- Understanding bowel vascular anatomy is crucial for successful and safe embolization procedures.
- Catheter-directed therapies provide valuable options for managing complex gastrointestinal bleeding.
- Awareness of potential complications guides clinical decision-making in interventional treatment of bowel hemorrhage.
Abstract:
The relevant findings in 11 cases of per catheter control of haemorrhage from different sites in the large and small bowel are presented together with a description of the techniques and some of the possible complications of vasopressin infusion and gelfoam embolisation. In six of these cases vasopressin infusion was sus achieved by embolisation, three following the failure of vasopressin therapy. In one case embolisation of the ileo-colic artery produced a caecal infarct. Important differences in the vascular supply to the large and small bowel and their practical significance in embolisation are discussed.
