We present a series of four newborns diagnosed with complicated congenital vascular anomalies, with different localization: Congenital lymphatic malformation (CLM) on the left hemithorax extending on the left upper limb; congenital hepatic hemangioma (CHH) with important complications in the first 7 weeks of life; Kaposiform hemangioendothelioma (KHE) of the left lower limb complicated with Kasabach Merritt phenomenon (KMM) and most probable diffuse capillary malformation with overgrowth (DCMO). All patients were treated with combined antiproliferative therapy with sirolimus and propranolol. The initial dose of sirolimus was 0.45-0.5 mg/m 2 with doses adjusted according to plasmatic levels. Therapeutic intervals of sirolimus were considered at plasmatic levels of 7-12 ng/ml. Our aim was to use the lowest therapeutic dose in order to avoid possible side effects. Propranolol was initiated in doses of 0.5-1.0 mg/kg/day and was increased up to 3.0 mg/kg/day depending on tolerability. Following two months, every patient showed a marked reduction in the size of the mass, improvement in overall appearance or even calcification in the liver vascular tumor. No patient showed life threatening side effects to the treatment. Hypertriglyceridemia was the only side effect noted in all patients. This is in accordance with several international studies, which try to demonstrate the importance of sirolimus in neonatal vascular malformations in monotherapy or combined with different drugs.
Background: This study presents the experience gained in the Newborn Intensive Care Unit (NICU) at “M. S. Curie” Emergency Clinical Hospital for Children in Bucharest after performing a series of bedside surgery interventions on newborns with congenital diaphragmatic hernia (CDH). We evaluate the advantages, complications, immediate and long-term outcome as well as the morbidity. Methods: We conducted a retrospective analysis of the data for all patients operated on-site be-tween 2011 and 2020, in terms of pre- and post-operative stability, procedures performed, com-plications and outcomes. Results: Our study is based on data from ten cases of newborns, term or small for gestation age with birthweights ranging from 2300 to 3300 grams, operated, on average, on the fifth day of life. The main reasons for operating on-site were the hemodynamical instability and the need to ad-minister inhaled Nitic Oxide (iNO) and HFOV ventilation. There were no unforeseen events dur-ing surgery, no immediate postoperative complications and no surgery related mortality. One noticed drawback was the unfamiliarity of the surgery team with the new operating environment. Conclusions: Our experience indicates that bedside surgery improves the likelihood of survival for critically ill neonates suffering from CDH. No immediate complications could be associated with this practice. Keywords: congenital diaphragmatic hernia, severe pulmonary hypertension, bedside surgery, NICU infrastructure
We present the first successful case of extracorporeal membrane oxygenation (ECMO) at „M.S. Curie” Emergency Clinical Hospital for Children, Newborn Intensive Care Unit: a term neonate with cardiorespiratory failure secondary to left sided congenital diaphragmatic hernia. The patient was placed on veno-venous ECMO at three days of life; however, on the fourth day, due to unstable right ventricular function, conversion to veno-arterial ECMO was mandatory. At one week of life, the patient was operated on-site for diaphragmatic hernia without ECMO support and then reintroduced on ECMO immediately after the surgical procedure, being on ECMO support for a total of 8 days. Antithrombotic treatment was administered for significant occlusion of the right common carotid artery and right internal jugular vein (complication of the cannulation for ECMO) and also long term treatment for Persistent Pulmonary Hypertension was needed. The patient was discharged at the age of four months with moderate neurodevelopmental delay. The literature review indicates that neonatal ECMO procedure in Romania is still in its early stages. Despite this state, our current case proves that ECMO can be successfully performed with increased chances of survival for neonates with severe prognosis after failure of conventional therapy.
