The perfusion provision method during surgery for chronic thromboembolic pulmonary hypertension

In this article we compared the impact of different techniques of perfusion during surgery of chronic thromboembolic pulmonary hypertension - deep hypothermic circulatory arrest (DHCA) and antegrade cerebral perfusion (ACP) on the central nervous system and lung function. Patients were divided into two groups: the group with ACP and the group with DHCA. Two patients from the second group had signs of posthypoxic brain injury in the early postoperative period. There were no neurological complications in the ACP group. There were no significant differences in the respiratory index and mechanical ventilation time between the groups. The technique of the pulmonary thrombendarterectomy under moderate hypothermia with ACP makes it possible to avoid the negative impact of hypothermic circulatory arrest. Further studies are needed to confirm these data.
