Video-assisted thoracic sympathectomy (VATS) is feasible with an azygos lobe (AL). Awareness of this anatomical variation aids surgeons in successfully treating hyperhidrosis patients.
Area of Science:
- Thoracic Surgery
- Anatomy
- Medical Imaging
Background:
- An azygos lobe (AL) can complicate video-assisted thoracic sympathectomy (VATS).
- Hyperhidrosis is a condition treatable by thoracic sympathectomy.
- Surgeons may be unprepared for AL during VATS.
Purpose of the Study:
- To evaluate the feasibility and outcomes of VATS in hyperhidrosis patients with an azygos lobe.
- To describe surgical techniques and clinical evolution in these specific cases.
Main Methods:
- Retrospective review of 7 hyperhidrosis patients with an AL undergoing VATS.
- Description of surgical technique and postoperative management.
- Analysis of clinical outcomes and complications.
Main Results:
- VATS was successfully performed in all 7 patients with an AL.
- One patient required pleural drainage; another experienced partial atelectasis resolved with physiotherapy.
- All patients achieved complete success with the operation.
Conclusions:
- Video-assisted thoracic sympathectomy is a viable surgical option for hyperhidrosis even in the presence of an azygos lobe.
- Preoperative identification of an azygos lobe is beneficial for surgical planning and preparedness.
- Surgeons should be aware of this anatomical anomaly to ensure successful outcomes.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
