[Diagnosis and treatment of pulmonary sequestration]

To explore the clinical manifestations and treatment of pulmonary sequestration.

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

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.

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.
