Clinical experience of infantile hepatic hemangioma

Abstract

PurposeTo describe the clinical presentation, treatment preference, and relevant complications of infantile hepatic hemangioma (IHH) in propranolol era. MethodsThe National Taiwan University Hospital integrated Medical Database (NTUH-iMD) was used to enroll twenty-one cases of IHH diagnosed from 2006 to 2020. Medical charts were retrospectively reviewed. ResultsIn nine patients (42.9%), IHH was found incidentally, and in seven patients (33%), it was detected during postnatal self-paid ultrasonography. Focal disease was determined in 17 patients, multifocal disease in 1 patient, and diffuse disease in 3 patients. Patients with diffuse disease had a lower hemoglobulin level than patients with focal IHH (9.38 vs. 12.6 mg/dL, p = 0.045). Two patients had Kasabach-Merritt phenomenon (KMP), one had hypothyroidism, and one had both. All patients with KMP had focal hepatic hemangiomas. Among the 17 patients with focal IHH, nine were prescribed propranolol, one was treated by surgical resection of the tumor, and the others had expectant management. All patients with multifocal and diffuse IHH were administered propranolol. One infant (7.7%) treated with propranolol had bradycardia initially but it subsided after dose adjustment. ConclusionsMost IHH is found incidentally or detected during postnatal ultrasonography screening. Patients with large focal lesions should also be screened for associated complications. Propranolol is the drug of choice and a safe therapeutic option for IHH, especially for focal tumors >5 cm as well as multifocal and diffuse lesions.
