Pulmonary Sequestration and Surgical Treatment

Abstract

Pulmonary sequestration is nonfunctioning, abnormal pulmonary tissue existing inside or outside the visceral pleura. It is not connected to the tracheobronchial tree. In this study, the results of 8 patients, who were diagnosed with pulmonary sequestration and treated during hospitalization in Gülhane Military Medical Academy between 1996 and 2003, were reported. Sex, age, symptoms, diagnostic approach, operative findings, procedures and postoperative outcomes were reviewed. No postoperative complications were seen. In the long-term follow-up all patients were seen to be asymptomatic. We believe surgical resection is mandatory in order to avoid infection and destruction of the normal pulmonary parenchyma even in asymptomatic cases. Furthermore, when infection occurs, major resection such as lobectomy may be necessary rather than segmentectomy or wedge resection, which involves removal of minimal pulmonary parenchyma.

Pulmonary sequestration: a retrospective analysis of 2625 cases in China

“…It is usually classified as either extralobar (ELS) or intralobar (ILS). ELS is separated from normal lung tissue by its own visceral pleura, whereas ILS is incorporated within normal lung tissue [1]. The numerous published reports dealt only with a small number of cases.…”

Use of Embolization and Surgical Resection in a Case of Pulmonary Sequestration Manifesting with Hemoptysis

“…In our previous studies, we observed that sequestration is generally seen in the lower lobes and the abnormal artery inside the pulmonary ligament [1]. In addition, the fragile elastic structure of the abnormal artery makes it more susceptible to damage [4]. For this reason, during surgery, the inferior pulmonary ligament should be carefully dissected to avoid injury to the aberrant artery existing within it.…”

A case report of extralobar pulmonary sequestration in a dog

“…A spiral CT with contrast angiography and magnetic resonance imaging (MRI) are the diagnostic techniques of choice [5,7,11,[19][20][21][22][23][24][25][26] . The treatment of an extralobar sequestrum is mainly by surgical excision which removes the mass completely total of the sequestrum to reduce the risk of repeated infection [2,5,7,19,20,[27][28][29] . To the best of our knowledge, this study is the first reported case of extralobar pulmonary sequestration in a mixed-breed dog that describes.…”
