The identification of clinical subtypes and conditions that indicate increased risk for complications is essential for therapeutic success. ObjectivesTo identify risk factors for complications, recurrence and unaesthetic sequelae. MethodsRetrospective cohort of patients with infantile hemangiomas undergoing follow-up at the Dermatology Service of Universidade Federal de Ciências da Saúde de Porto Alegre, between 2006 and 2018. Results190 patients were included; 24% had some type of complication, ulceration being the most frequent, and 86% required treatment. On correlation, ulceration was statistically related to mixed IH (p = 0.004), segmental IH (p < 0.01) and location in the gluteal region (p = 0.001). The mean time of treatment with propranolol was 12.7 months. Patients with PHACES syndrome and segmental infantile hemangioma required longer treatment (p < 0.001 and p = 0.0407, respectively), as well as those who started treatment after five months of life (p < 0.0001). Recurrence occurred in 16.6% of the treated patients, all-female; 94% were located on the head and neck (mainly on the upper eyelid, cyrano, S3 segment, and with parotid involvement); 61% and 38.8% were of the mixed and deep subtypes, respectively. Approximately 1/3 of the patients had some unaesthetic sequelae. Study limitationsAs this is a retrospective study, data and photos of some patients were lost. ConclusionsMixed and segmental hemangiomas are risk factors for ulceration and sequelae. Recurrence occurs more often in females and segmental hemangiomas. Segmental infantile hemangioma and PHACES syndrome require a longer time of treatment. Specific protocols are required for infantile hemangiomas with a high risk of recurrence. ER -
