Transcatheter control of postpolypectomy hemorrhage
Gastrointestinal Radiology
|January 1, 1986
Summary
Intraarterial vasopressin infusion effectively treated massive post-polypectomy hemorrhage in high-risk patients. Angiography guided treatment, avoiding immediate surgery and leading to successful outcomes.
Area of Science:
- Gastroenterology
- Interventional Radiology
- Vascular Medicine
Background:
- Massive hemorrhage post-colonoscopic polypectomy poses a significant risk, especially in patients with comorbidities.
- Emergency surgery is often high-risk for these patients.
Observation:
- Two high-risk patients with massive post-polypectomy hemorrhage were treated with intraarterial vasopressin infusion via the inferior mesenteric artery.
- Arteriography successfully identified the bleeding source in both cases.
Findings:
- Vasopressin infusion effectively controlled hemorrhage in both patients without complications.
- One patient underwent elective colonic resection later, while the other avoided surgery and remained hemorrhage-free for six months.
Implications:
- Arteriography and vasopressin infusion offer a viable, less invasive treatment for post-polypectomy hemorrhage.
- This approach can help avoid high-risk emergency surgery in select patient populations.
