Diagnosis and treatment of pulmonary sequestration

Objective: To explore the clinical manifestations and treatment of pulmonary sequestration.

Methods: Thirty-five patients with pulmonary sequestration confirmed by pathological studies were analyzed.

Results: Among these patients, 29 were of intralobar type and 6 of extralobar type. All patients of intralobar type had symptoms of cough, expectoration, fever and hemoptysis while 6 cases of extralobar type were asymptomatic. Twenty-three cases were diagnosed preoperatively by enhanced CT scan, CT angiography or selective arteriography. Success of operation had been achieved in all cases.

Conclusions: The clinical manifestations of pulmonary sequestration are non-specific. Though invasive, selective arteriography plays a decisive role in the diagnosis. Such non-invasive angiographies as enhanced CT scan and CT angiography have become important supplements to it. Once the diagnosis is confirmed, operation should be performed.
