Abstract: (148 Views)
Introduction: Phrenic nerve injury is the most frequently observed complication during heart-related surgeries. Therefore, accurate descriptions of anatomy and its branches are very important. The accessory phrenic nerve (APN) is one of the related branches of the phrenic nerve. This study aimed to evaluate the prevalence of accessory phrenic nerve and its anatomic variations.
Methods: 26 male adult cadavers were dissected using Grant`s method, resulting in 52 nerve specimens. We evaluate phrenic nerve branches and explore the presence or absence of APNs. All the parameters in each cadaver were examined bilaterally and the parameters were recorded in pre-prepared tables.
Results: Our findings demonstrated that the total prevalence of APN was 30.77% (8 of 26 cadavers). In 5 cases, the presence of APN was two-sided and in 3 cases was one-sided (two left-sided and one right-sided). In 5 cadavers the APN originated from the root of the fifth cervical nerve and in 3 cases APN was a branch from the nerve to the subclavius.
Conclusion: The frequency and variable origin of APNs will help clinicians and surgeons while performing internal thoracic surgery.
