Objective: The aim: To revise the case-series of hepatic vascular tumors (HVT), particularly to identify optimal visualization, management and role of surgical intervention.
Patients and methods: Materials and methods: Out of 96 children with hepatic tumors who hospitalized in a single center from 2011 to 2020, 20 (20,8%) were diagnosed HVT. Hepatic Hemangiomas (HHs) were presented in 19 patients and Kaposiform hemangioendotelioma (KHE) in one case. To determine the type of HH we used radiological classification. For visualisation contrast-enhanced MRI (n=7, 30%) and cCT (n=15,70%) were used. Follow-up period was 14-77 months.
Results: Results: All HVT were revealed by sonogram at the age of 0-5 m, with 4 (20%) diagnosed prenatally. Male to female ratio was 3:2. Beta-blockers were prescribed to 12 patients with HHs. Treatment duration was from 6 to 24 month. Steroid therapy was initial in cases when it was impossible to prescribe the curative dose of beta-blockers. Complications of propranolol treatment were transitory bradycardia (n=7) and transitory hypoglycemia (n=2). After vincristine chemotherapy decreases the tumor size by 54%, that allowed a safe liver resection. 4 (20%) patients - two multifocal HHs, one diffuse HH and in patient with KHE manifested congestive heart failure and pulmonary hypertension Mortality rate is 5% (n=1), this patient died against progressive cardiovascular failure.
Conclusion: Conclusions: life-threatening complication of HVT was congestive heart failure. Early treatment is beneficial for complications prevention. Surgical treatment is optional for KHE when can be removed safely.
