[Effect of intravenous administration of coagulation factor XIII concentrate on persistent pleural air leak].

ABSTRACT

We administered coagulation factor XIII concentrate intravenously to six patients suffering from persistent air leak with no evidence of bronchopleural fistulae They are those who had either failed to be healed in response to pleurodesis, intrapleural fibrin glue injection and surgery or had not received such treatment. Their blood coagulation factor XIII activity levels were less than 70% of the standard plasma level. In four of the six patients, air leak stopped within 10 days after the treatment begun. Because factor XIII plays an important role in wound healing, reduction in the activity level can be a cause of insufficient healing of pulmonary surface fistulae and may lead to persistent air leak. In such cases, intravenous administration of factor XIII concentrate increases the activity levels and may put an end to persistent air leak.
