“…Although cases of phrenic nerve abnormalities are relatively uncommon, clinicians should still pay close attention to them. [1] 1. When the phrenic nerve is irritated, it can induce spastic contractions of the diaphragm, potentially leading to singultus.…”

Background The phrenic nerve is an important efferent nerve of the cervical plexus, and its anatomical structural variations have clinical reference value. Methods Adult neck specimens were obtained through the Morphology Experimental Center and dissected under a surgical microscope. Results The phrenic nerve trunk courses along the fascia, situated above the anterior and middle scalene muscles. It then courses anteriorly and inferiorly before bifurcating into two branches - internal and external branch - approximately 1.5 mm later. Inside the thoracic cavity, the internal and lateral branches reunite to form the phrenic nerve. Conclusions This report on the anatomical variations of the phrenic nerve has certain clinical value

“…During the travel, it is adjacent to the internal jugular vein, the total jugular/ascending artery, the subclavian artery/vein, the internal thoracic artery, the superior vena cava, the right upper pulmonary vein, the pericardial diaphragm artery, other important organs. [11] In traditional operations, such as cardiac surgery, right upper pulmonary vein intervention, and transdiaphragmatic approach surgery, the phrenic nerve is susceptible to injury. Aphrodisiac injury of 1 side phrenic nerve may cause ipsilateral shoulder radiation pain or mild dyspnea.…”

Introduction: Diaphragm is one of the most important respiratory muscles dominated by the phrenic nerve. Phrenic nerve injury would induce a series of clinical symptoms, including respiratory failure. Respiratory training could assist in regular treatment in improving the respiratory function and daily ability of respiratory failure patients.Case presentation: A 71-years-old female was enrolled for the disorders of consciousness of 4.5 hours observed by her family and was diagnosed with respiratory failure secondary to unilateral phrenic nerve injury. The patient received basic therapy combined with rehabilitation training, including the training of aspirate muscle, limb resistance, thoracic loosening, aerobic training, electrical stimulation on respiratory nerves, and airway clearance. The combining therapeutic strategy significantly improved the daily ability and respiratory of the patient. The ultrasound showed that after therapy, the diaphragmatic muscles were thickened and the range of diaphragmatic movement was also enhanced. The pulmonary function was also improved after therapy. Conclusion:The combination of rehabilitation is suitable for the treatment of respiratory failure patients with clear causes of phrenic nerve injury. For patients with unexplained causes, rehabilitation could also be performed before the diagnosis. Patients with irreversible injury need long-term and family rehabilitation prescriptions.Abbreviations: FEV1 = forced expiratory volume in the first second, FVC = forced vital capacity.

“…Moreover, in the current case, the phrenic nerve (branch of the cervical plexus) was interconnected to the LTN (branch of the BP). Goyal and Jain [ 17 ] reported an interconnection of the phrenic nerve with the upper trunk of the BP, in its early course in the neck. Although the phrenic nerve has a great clinical interest in the diaphragm supply, the majority of the published studies investigated its anatomy within the thorax [ 14 ].…”

The axillary artery is the continuation of the subclavian artery. Occasionally, some of the subclavian artery’s distal branches may atypically originate from the axillary artery, such as the suprascapular artery. The suprascapular artery’s distal (low) origin from the axillary artery, instead of the subclavian artery, may also be characterized as an aberrant suprascapular artery. The current cadaveric report describes the coexistence of an aberrant suprascapular artery (of axillary origin), variant course, and termination with atypically formatted nerves originating from the cervical (the phrenic nerve) and the brachial (the long thoracic and the median nerves) plexus. An unusual interconnection between the phrenic and the long thoracic nerves was also described. The aberrant suprascapular artery had an atypical termination below the superior transverse scapular ligament, along with the suprascapular vein and nerve. Except for the atypically formatted phrenic and long thoracic nerves, the aberrant suprascapular artery coexisted with an atypical passage of the anterior ramus of the C6 spinal nerve, through the middle scalene muscle, before the long thoracic nerve formation, and a variant formation of the median nerve. Understanding neurovascular variants is crucial for interventionists and surgeons who work in the supra- and infraclavicular areas. Being aware of the different origins of the brachial plexus branches, in the supraclavicular part, may help reduce the occurrence of iatrogenic axillary injury. Efforts should be made to expand the number of cadaveric studies that investigate the origin, course, interconnection, and branching patterns of these nerves and related covariants, in a systematic way, thus unifying their study and comprehension.
