Digital Arteriovenous Malformation. An Uncommon Finding: A Case Report

Vascular malformations (VMs) are dysplastic abnormalities of vascular channels, differing from vascular tumors by their slow growth. Arteriovenous malformations (AVMs) arise between weeks 4-10 of intrauterine life, with a prevalence of 1 in 100,000 among Caucasians. Common in the head, neck, and hands, AVMs may be asymptomatic or cause symptoms like pain, deformity, and disability. Treatments range from conservative management to amputation in severe cases. A 28-year-old male with finger trauma was found to have a vascular tumor, later diagnosed as an arteriovenous malformation, surgically removed and confirmed by histopathology. Angiography is the gold standard for diagnosing AVMs, though imaging and physical exams are often sufficient. Conservative management is preferred for minor symptoms, with surgery reserved for severe cases. Surgical intervention carries risks, especially for diffuse lesions. Treatment for hand AVMs is challenging, requiring specialized expertise due to the hand's complex anatomy.
