“…16 These authors reported more caudal and even thoracic nerves adding branches to the phrenic nerve, and thus recommended tearing the phrenic nerve out of the thoracic cavity by using clamps to ensure paresis. 3 Current studies, however, could not confirm the findings of thoracic accessory branches. Cervicobrachial accessory phrenic nerves that were not divided during surgery could be an explanation for functional differences, but anatomical dissections in rabbits showed more cervical accessory phrenic nerves on the right side (43%) than on the left side (28%).…”

“…It has been shown that such branches can arise from the ventral branch of the first to third cervical spinal nerves or from the sympathetic trunk (via grey rami communicantes), which may even reach the diaphragm entirely independent of the phrenic nerve [ 1 , 2 ]. This phenomenon was first described by Felix et al in 1922 [ 17 , 27 ]. The presence of intrathoracic accessory would strengthen the use of a supraclavicular approach in combination with an autograft to restore elbow flexor muscle function and maintain a residual function of the nerve at the affected side, even in patients without accessory phrenic nerve.…”

Background: To restore elbow flexor muscle function in case of traumatic brachial plexus avulsion, the phrenic nerve transfer to the musculocutaneous nerve has become part of clinical practice. The nerve transfer can be done by means of video-assisted thoracic surgery without nerve graft or via supraclavicular approach in combination with an autograft. This study focuses on a detailed microscopic and macroscopic examination of the phrenic nerve. It will allow a better interpretation of existing clinical results and, thus, serve as a basis for future clinical studies. Material and Methods: An anatomical study was conducted on 28 body donors of Caucasian origin (female n = 14, male n = 14). A sliding caliper and measuring tape were used to measure the diameter and length of the nerves. Sudan black staining was performed on 15 µm thick cryostat sections mounted on glass slides and the number of axons was determined by the ImageJ counting tool. In 23 individuals, the phrenic nerve could be examined on both sides. In 5 individuals, however, only one side was examined. Thus, a total of 51 nerves were examined. Results: The mean length of the left phrenic nerves (33 cm (29–38 cm)) was significantly longer compared to the mean length of the right phrenic nerves (30 cm (24–33 cm)) (p < 0.001). Accessory phrenic nerves were present in 9 of 51 (18%) phrenic nerves. The mean number of phrenic nerves axons at the level of the first intercostal space in body donors with a right accessory phrenic nerve was significantly greater compared to the mean number of phrenic nerves axons at the same level in body donors without a right accessory phrenic nerve (3145 (range, 2688–3877) vs. 2278 (range, 1558–3276)), p = 0.034. A negative correlation was registered between age and the nerve number of axons in left (0.742, p < 0.001) and right (−0.273, p = 0.197) phrenic nerves. The mean distance from the upper edge of the ventral ramus of the fourth cervical spinal nerve to the point of entrance of the musculocutaneous nerve between the two parts of the coracobrachialis muscle was 19 cm (range, 15–24 cm) for the right and 20 cm (range, 15–25 cm) for the left arm. Conclusions: If an accessory phrenic nerve is available, it presumably should be spared. Thus, in that case, a supraclavicular approach in combination with a nerve graft would probably be of advantage.

“…Felix (9) in 1922 by histological examination of the serial sections of a human fetus spinal cord , stated that the 12th intercostal nerve supplies the muscle fibres from the same rib and that the crural part is innervated by the phrenic nerves and sympathetic branches from the coeliac plexus .…”

“…One insists that the phrenic nerve only supplies motor impulses to the diaphragm (2,11,16,20,21). Another opinion is that besides the phrenic nerve there is one more innervation by intercostal nerves providing efferent components for the diaphragm (5,9,19).…”
