Patient Population:
With the approval of the institutional ethics committee, 92 consecutive
patients who underwent the Fontan operation between January 2017 and
December 2019 were retrospectively analyzed. A protocol-based
postoperative management was adopted at July 2018. Patients operated
before the protocol were defined as Group 1 (n = 48), and patients
operated after the protocol were defined as Group 2 (n = 44). Patients
who underwent hepatic re-routing and a single-stage Fontan procedure
were also included in the study.
All patients underwent a cardiac catheterization before Fontan
procedure. Mean pulmonary artery pressure (mPAP), pulmonary vascular
resistance (PVR), transpulmonic gradient (TPG), McGoon and Nakata
indexes, right pulmonary artery and left pulmonary artery z-scores,
ventricular end-diastolic pressure were calculated. In echocardiographic
examination, ventricular functions, atrioventricular valve
insufficiency, ventricular outflow tract obstruction were evaluated.
Postoperative drainage output, chest tube duration, reinsertion of chest
tube, mechanichal ventilation, ICU and LOHS and rehospitalization
(within 30 days postoperatively) were recorded.
