Lung sequestration: Managements
If it is symptomatic, it will perform advanced imaging soon after surgery. Intralobar sequestration is removed through lobectomy and segmental resection, and extralobar sequestration removes lesions. Since all vessels are connected from the systemic circulation, it is important to ligate all vessels well. Other operations include thoracoscopic lobectomy and arterial embolization.
If asymptomatic, early surgical resection is available if:
- Large lesion (occupies ≥ 20 percent of the lobe)
- Characteristics suggesting risk for pleuropulmonary blastoma (family history, bilateral or multifocal cysts, and pneumothorax)
Even if it does not meet the above criteria, elective surgical resection will be done. This will be done mainly at 6 to 12 months, and will be performed for the following reasons.
- Therapeutic purpose is strong because it can cause serious complications.
Patients with Lung sequestration are more susceptible to infection later. (Especially intralobar sequestration)
- It is difficult to distinguish other dangerous hybrid lesions that can cause malignant change or infection by imaging alone.
You can watch without surgery. Lesion shows a small, non-cystic appearance and extralobar sequestration can be followed up with advanced imaging such as CT or MRI.
