Case Report: Acute cardiac tamponade due to spontaneous bleeding in a child with Haemophilia A

In severe haemophilia a, patients, start from the first years of life, with spontaneous bleeding and require transfusion. however, cardiac tamponade due to spontaneous pericardial bleeding is rare. an 11-year-old boy receiving haemophilia a treatment was referred to the department of paediatric haematology with pneumonia, fever, dyspnoea, and palpitation. in his pa chest radiograph, pneumonic infiltration in the right lung and enlargement in the pericardial area were found. on his echocardiograph, pericardial effusion reaching 3.9 cm and other findings of tamponade were detected. aptt was outside the measurable range. it was deranged to >120 seconds. the patient received 1000 u of factor viii intravenously. a pericardial window was made via left anterior mini thoracotomy due to fluid drained. in his control echocardiograph taken after one month, no pathology was found. at 50th day, the patient showed left pleural serohaemorrhagic effusion, which was treated with tube thoracostomy. in haemophilia a patients, either pericardiocentesis or subxiphoid pericardial drainage or pericardial window creation via thoracotomy may be applied, depending on the primary pathology. in paediatric cases, pericardial window creation via mini thoracotomy can be an alternative treatment of choice considering complications such as recurring bleeding and effusion during pericardiocentesis.
