Abstract
Purpose: Although arteriovenous malformations (AVMs) are typically benign lesions, massive ones can lead to severe complications, including heart failure. Notably, there is no standardized treatment for AVMs. Moreover, management of AVMs can be challenging when these lesions involve vital organ systems, such as the head and neck. In this report, we describe embolization of a massive cervical AVM in a pediatric patient with heart failure.
Case report: A 10-year-old boy presented with severe heart failure secondary to a massive AVM in the neck (right side). Despite 3 unsuccessful arterial embolization procedures, venous embolization of the dominant outflow vein using a coil and n-butyl-2-cyanoacrylate, lipiodol, and ethanol proved effective, and symptoms, cerebral natriuretic peptide level (568-29 pg/mL), and echocardiography were significantly improved. Although residual AVM persisted in the right upper extremity for 6 months after surgery, his cardiac function remained preserved, and his activities of daily living have improved.
Conclusion: Venous embolization is a valuable treatment modality for type II AVMs with a dominant outflow vein. However, considering the patient burden associated with large AVMs, multiple therapeutic interventions at appropriate intervals and long-term follow-up are important.
Clinical impact: We present a pediatric patient with a type II massive arteriovenous malformation (AVM) in the neck and severe heart failure. Despite undergoing 3 arterial embolization procedures, his condition remained unchanged. However, venous embolization of the dominant outflow vein resulted in a significant improvement in symptoms. This case emphasizes the importance of considering multiple and appropriately timed therapeutic interventions, particularly for massive AVMs, to optimize patient outcomes while minimizing treatment burden.
期刊介绍:
The Journal of Endovascular Therapy (formerly the Journal of Endovascular Surgery) was established in 1994 as a forum for all physicians, scientists, and allied healthcare professionals who are engaged or interested in peripheral endovascular techniques and technology. An official publication of the International Society of Endovascular Specialists (ISEVS), the Journal of Endovascular Therapy publishes peer-reviewed articles of interest to clinicians and researchers in the field of peripheral endovascular interventions.
