Phrenic nerve reconstruction in complete video-assisted thoracic surgery

Area of Science:

• Thoracic surgery
• Neurosurgery
• Surgical oncology

Background:

• Phrenic nerve involvement in lung/mediastinal tumors necessitates resection, leading to paralysis.
• Phrenic nerve paralysis impairs pulmonary function and quality of life.
• Immediate reconstruction is explored to prevent functional decline.

Purpose of the Study:

• To evaluate the utility of complete video-assisted thoracic surgery (VATS) for immediate phrenic nerve reconstruction.
• To assess functional outcomes following phrenic nerve repair after tumor resection.

Main Methods:

• Six patients underwent complete VATS phrenic nerve reconstruction (Oct 2009-Dec 2013).
• Reconstruction methods included direct anastomosis (3 cases) and intercostal nerve interposition (3 cases).
• Phrenic nerve function and diaphragm movement were assessed postoperatively.

Main Results:

• Successful reconstruction in 5 out of 6 patients.
• Intercostal nerve interposition was effective in all 3 cases.
• Direct anastomosis was effective in 2 out of 3 cases.
• Improved diaphragm function observed on chest X-ray.

Conclusions:

• Complete VATS phrenic nerve reconstruction is effective for both direct and interpositional anastomosis.
• The procedure offers a promising solution for preserving pulmonary function after nerve resection.
• Further data collection is recommended to support these findings.
