PURPOSE OF REVIEW: Hereditary hemorrhagic telangiectasia (HHT) diagnostic and management approach for pediatrics underwent significant advances over the last couple of years.
RECENT FINDINGS: In 2020, new guidelines for HHT were published that included a pediatric section thus attracting special focus into the childhood presentation.
SUMMARY: Curacao criteria are specific, but not sensitive enough in children. Genetic testing is encouraged for all family members even if asymptomatic. Standardized scoring for epistaxis is strongly encouraged, as it allows monitoring and can stratify therapeutic approaches. Early screening for pulmonary and brain visceral arteriovenous malformations (AVMs) in pediatric patients with confirmed genetic alterations of HHT should be instituted. Graded trans-esophageal echocardiogram with agitated saline contrast can be used as screening method for pulmonary AVMs. As pulmonary AVMs can develop throughout lifetime, guidelines recommend repeated screening even in asymptomatic patients at least every 5 years. Signs of stroke in childhood are more subtle than in adults. Cerebral imaging in early childhood can identify brain AVMs that may benefit from early intervention. Embolization of high-risk pulmonary and cerebral AVMs should be performed at specialized centers even at pediatric age. One or two classic HHT telangiectasia can be considered diagnostic in children. Antibiotic prophylaxis with dental procedures continues to be recommended.
