diagnosis of Pulmonary Sequestration by spiral ct angiography
Thorax, 1998Co-Authors: Jose Franco, Roberto Aliaga, Maria L Domingo, Pedro PlazaAbstract:The diagnosis of Pulmonary Sequestration traditionally requires arteriography to identify abnormal systemic vessels feeding the abnormal portion of the lung. Non-invasive imaging techniques have recently been used to replace arteriography. Conventional computed tomographic (CT) scanning is, however, at a disadvantage because of its inability to obtain multiplanar images. The combination of slip ring CT scanning and computerised three-dimensional reconstruction (spiral CT angiography) can be used to visualise the anatomical detail of a wide range of vessels within the lung. Four cases of Pulmonary Sequestration are reported which were successfully diagnosed using spiral CT angiography. Spiral CT scanning allows simultaneous imaging of anomalous vessels and lung parenchyma in a single examination and is particularly useful in the diagnosis and assessment of Pulmonary Sequestration.

Pulmonary Sequestration demonstration of blood supply with 2d and 3d mr angiography
European Journal of Radiology, 2002Co-Authors: Stefan Lehnhardt, Jan Thornsten Winterer, Peter Uhrmeister, Georg Herget, Joerg LaubenbergerAbstract:Pulmonary Sequestration is a relatively rare but clinically significant congenital anomaly. This disease is a spectrum of disorders involving the Pulmonary airways, the arterial supply to the lungs, the lung parenchyma and its venous drainage. Traditionally, the diagnosis of Pulmonary Sequestration has been made definitively with arterial angiography. It is imperative for the preoperative evaluation that the arterial supply and venous drainage of the sequestered segment is identified. Several cases of MR diagnosis and preoperative evaluation of Pulmonary Sequestration and blood supply have been reported. In this case, MR imaging was able to provide important information about systemic blood supply via intercostal arteries and regular venous drainage. Furthermore this imaging technique revealed a second Pulmonary Sequestration in the dorsal phrenicocostal sinus that was not diagnosed before.

video assisted thoracoscopic wedge resection for Pulmonary Sequestration
The Annals of Thoracic Surgery, 2004Co-Authors: Tsutomu Sakuma, Makoto Sugita, Motoyasu Sagawa, Masanobu Ishigaki, Hirohisa TogaAbstract:Abstract A 60-year-old woman underwent a video-assisted thoracoscopic wedge resection of intralobar Pulmonary Sequestration instead of a lobotomy because the lesion was localized in the right basal segment. Preoperative 3-dimensional computed tomography was useful for identifying an aberrant artery arising from the thoracic aorta and distributing to the lesion. A successful outcome more than 4 years after the surgery indicates that a wedge resection under video-assisted thoracoscopy may prove to be a therapeutic option for localized Pulmonary Sequestration.

Pulmonary Sequestration a review of 26 cases
European Journal of Cardio-Thoracic Surgery, 1998Co-Authors: N Halkic, P F Cuenoud, M E Corthesy, R Ksontini, M BoumgharAbstract:Objectives: Pulmonary Sequestration is a continuum of lung anomalies for which no single embryonic hypothesis is yet available. The aim of this study was to assess the diagnostic tools and treatment for the rare condition, Pulmonary Sequestration, in an unspecialised centre. Methods: We performed an analysis of 26 cases of Pulmonary Sequestration (paediatric and adult) operated at the Centre Hospitalier Universitaire Vaudois between May 1959 and May 1997. A review of the extralobar and intralobar types of Sequestrations is discussed. Angiography is compared to other diagnostic tools in this condition, and treatment is discussed. Results: Twenty-six cases of Pulmonary Sequestrations, a rare congenital Pulmonary malformation, were operated on in the defined time period. Seventy-three percent (19) of the cases were intralobar and 27% (seven) extralobar. Extralobar localisation was basal in 71% and situated between the upper and the lower lobe in 29%. In six cases, the diagnosis was made by exploratory thoracotomy. In the other 20 cases, diagnosis was evoked on chest X-ray and confirmed by angiography. Lobectomy (46%) was the most common treatment procedure. Segmental resection was performed in 30% of the cases and bilobectomy in 4%, Post-operative morbidity was low. The most significant complications were pleural empyema, haemothorax and haemopneumoperitoneum in case of extralobar Sequestration. There was no evidence of metaplasia or pre-neoplastic changes. Conclusions: Despite its rarity, some radiological features are sufficiently suggestive of diagnosis of Pulmonary Sequestration. Investigations are necessary in order to avoid unexpected pathology at the time of operation. Resection of the involved lung leads to excellent results and the long-term outcome is highly favourable.
