Summary
Selective embolotherapy effectively palliates congenital arteriovenous malformations (AVMs). This minimally invasive treatment significantly reduces pain, ulceration, and bleeding in patients with pelvic or extremity AVMs, offering lasting symptom relief.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Devices
Background:
- Congenital arteriovenous malformations (AVMs) can cause significant morbidity.
- Symptomatic AVMs often require intervention to manage pain, ulceration, and bleeding.
Purpose of the Study:
- To evaluate the efficacy of tailored embolotherapy for congenital AVMs.
- To assess long-term outcomes and recurrence rates following embolization.
Main Methods:
- 16 symptomatic patients with pelvic or extremity AVMs underwent embolization.
- Permanent occlusive agents (isobutyl cyanoacrylate, polyvinyl alcohol foam, coils) were used.
- Treatment targeted feeding vessels and AVM nidus.
Main Results:
- All treated patients showed dramatic reduction in pain and resolution of ulceration/bleeding.
- Mean follow-up was 41 months.
- Four patients experienced recurrence, successfully managed with repeat embolization.
Conclusions:
- Selective and repetitive embolization is highly effective for palliation of symptomatic congenital AVMs.
- Embolotherapy offers a durable solution for managing complex vascular malformations.
