Summary
Postoperative lingula ischemia after lung surgery is often wrongly blamed on twisting. Reoperation cases reveal that venous issues, not torsion, are the primary cause of this complication.
Area of Science:
- Thoracic Surgery
- Surgical Complications
- Pulmonary Anatomy
Background:
- Postoperative lingula ischemia is a known complication following left upper lobe trisegmentectomy.
- It is typically attributed to torsion of the remaining lingula.
- However, other factors like venous interruption may also contribute.
Purpose of the Study:
- To investigate the causes of postoperative lingula ischemia in patients undergoing reoperation after lingula-sparing left upper lobectomy.
- To determine if torsion is the primary cause or if other factors are involved.
Main Methods:
- Retrospective review of 3 cases requiring reoperation for suspected lingula ischemia post-lung surgery.
- Analysis of surgical findings during reoperation to identify the cause of ischemia.
Main Results:
- None of the 3 reoperation cases were found to be caused by lingula torsion.
- In all cases, the ischemia was linked to accidental injury of the lingular venous drainage or an abnormal venous pattern.
Conclusions:
- Lingula ischemia after lung surgery is not primarily caused by torsion.
- Accidental injury to lingular venous drainage or unusual venous anatomy are the likely culprits.
- This highlights the importance of careful surgical technique regarding lingular vasculature.

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
