The oversewn stump of the homograft pulmonary trunk was sutured anterior to the right phrenic nerve for later retrieval.
Topical cooling is achieved with slush or cold saline and a swab is used to protect the phrenic nerve.
Fluoroscopy of the chest revealed the cause of prolonged respiratory failure to be unilateral phrenic nerve palsy.
The distal oesophagus receives blood from the oesophageal branches of the inferior phrenic and left gastric arteries.
The pericardium is completely freed on the right side from the parietal pleura so that aflapcan be fashioned which remains in continuity with its base adjacent to the phrenic nerve.
We undertook phrenic nerve stimulation study on 55 children (ages 2 weeks to 11 years) before and after cardiac surgery and at outpatient follow-up 3 months to 1 year later.
The main pulmonary artery end of the homograft is prepared by excising the valve, oversewing, then tucking this "stump" anterior to the phrenic nerve for later use.
These hiccups are part of fetal development and are associated with the myelination of the phrenic nerve, which primarily controls the thoracic diaphragm.
