Objective 1) To demonstrate the natural history of arteriovenous malformation (AVMs) when left untreated or inadequately managed. 2) To demonstrate the need for major treatment to patients, families, healthcare providers, and insurance companies. Methods Records from 10 of 50 representative patients treated at University of Arkansas for Medical Sciences (UAMS) for advanced AVMs were reviewed for age at presentation, gender, presenting symptoms, previous treatment, disease course, and post-presentation management. Patients were asked if quality of life had improved after treatment at UAMS Facial photos from childhood were obtained and compared with photos taken at time of presentation. Results 10 patients (7 male, 3 female, range 21–46 years) received treatment. All patients presented with bleeding, pain and/or facial destruction. 6 of 10 patients received previous embolization. No patients had undergone previous surgical resection. All were informed by a previous physician that the disease was incurable or treatment options had been exhausted. All patients experienced subsequent worsening of symptoMS All patients were treated at UAMS with preoperative embolization followed by surgical resection and required multiple surgeries to remove persistent AVM. All patients indicated quality of life improved after embolization/surgical resection. Comparison of photos revealed progression of disease in all cases marked by facial destruction and deformity. Conclusions AVMs display a progressive and destructive nature when left untreated or inadequately managed. Natural history can be used to demonstrate to patients, families, and healthcare providers the seriousness of disease and convince insurance companies that radical treatment is typically necessary to obtain control or cure.
