Clinical analysis of diagnosis and surgical treatment of pulmonary sequestration

Abstract

Objective To summarize the experience in the diagnosis and surgical treatment of pulmonary sequestration. Method The clinical data from 15 patients with pulmonary sequestration underwent surgical operation from July 2000 to January 2009 were reviewed and analyzed retrospectively. Results Pulmonary sequestration was diagnosed in 14 patients before the operation with the diagnosis rate of 93.33% (14 /15).Preoperation plane and contrast chest CT scan were performed in all cases,and 9 patients performed angiography reconstruction. Twelve patients with intralobar sequestration underwent lobectomy and 3 patients with extralobular sequestration underwent local lesion resection. Abnormal supply arteries were intraoperatively found in 14 patients originating from the thoracic main artery, 1 patient from the eeliac artery. Smooth recovery was achieved in all patients. No perioperarive death occurred. Conclusions Pulmonary sequestration is a rare disease with high misdiagnosis rate in some patients. Contrast enhanced CT scan and angiography may improve the diagnosis of pulmonary sequestration. Operation is a safe and effective method for the treatment of pulmonary sequestration.
