Pulmonary sequestration and endovascular treatment: a case report

Area of Science:

• Pulmonology
• Vascular Surgery
• Congenital Anomalies

Background:

• Pulmonary sequestration is a congenital lung malformation characterized by non-functional lung tissue.
• It is classified as intralobar (75%) or extralobar (25%) based on the presence of a separate pleural envelope.
• Diagnosis typically involves imaging techniques like CT, MRI, or angiography.

Observation:

• A 29-year-old woman experienced recurrent pneumonia over five years.
• Chest CT revealed abnormal vascularization in the lower right lung, indicative of pulmonary sequestration.
• The patient had a history of recurrent pneumonia for 5 years.

Findings:

• The pulmonary sequestration was identified as the cause of the recurrent pneumonia.
• Endovascular treatment using embolization of the anomalous artery was performed.
• The anomalous branch feeding the sequestration was successfully embolized.

Implications:

• Endovascular embolization offers a minimally invasive alternative to traditional open surgery for pulmonary sequestration.
• This case highlights the effectiveness of embolization in managing symptomatic pulmonary sequestration.
• Successful embolization can resolve recurrent pulmonary infections associated with this congenital anomaly.
