What is considered the gold standard for diagnosis of pulmonary sequestration?
However, the gold standard for identifying the pulmonary sequestration recently is CT/MR angiography as it confirms the anatomy, identifies the anomalous systemic arterial supply, and shows the venous drainage .
What is the investigation of choice for sequestration lung?
By allowing simultaneous imaging of anomalous vessels and parenchymal lesions in a single examination, spiral CT angiography is a particularly efficacious technique and has the potential to become the procedure of choice in the diagnosis and assessment of pulmonary sequestration.
What causes pulmonary sequestration?
The cause of pulmonary sequestration is unknown. Research does show that sometime during the development of the fetus in the womb, lung tissue will form abnormally, and the baby will be born with the lump or cyst.
What is the most common form of pulmonary sequestration?
The PS is divided into two types, intralobar sequestration (ILS) which is the more common type, where the lesion lies within pleural layer surrounding the lobar lung and extralobar sequestration (ELS) which has its own pleural covering, maintaining complete anatomic separation from adjacent normal lung .
What is Extralobar sequestration?
Intralobar sequestration (ILS) is abnormal lung tissue surrounded by normal lung pleura, while extralobar sequestration has its own separate pleura. Extralobar sequestration is less common than its intralobar counterpart and comprises approximately 25% of all sequestrations.
What is Intralobar pulmonary sequestration?
Intralobar pulmonary sequestration is characterized by the presence of nonfunctional parenchymal lung tissue, receiving systemic arterial blood supply. It lacks normal communication with tracheobronchial tree. Failure to diagnose and treat this condition can lead to recurrent pneumonia and fatal hemoptysis.
What is lung sequestration?
Bronchopulmonary sequestration, also known as BPS or pulmonary sequestration, is a rare birth defect in which an abnormal mass of nonfunctioning lung tissue forms during prenatal development. It can form outside (extralobar) or inside (intralobar) the lungs, but is not connected directly to the airways.
What is under sequestration?
The term sequestration is used when the estate of a person is sequestrated (that is, the estate of a person who is no longer able to pay his or her debts due to uncontrollable circumstances is surrendered by order of the court). The estate of natural persons, partnerships and trusts can be sequestrated.
Is pulmonary sequestration life threatening?
While it is not in itself a life-threatening condition, a pulmonary sequestration can cause health complications including cardiovascular problems, long-term infections like tuberculosis, and bronchial cancer. It could be fatal if blood vessels in the lung begin to hemorrhage.
What is CPAM in fetus?
CPAM are lesions (abnormal areas of tissue) on the lung that happen when the airway does not develop properly. They are the most common type of congenital lung abnormality. Most babies with CPAM can be delivered normally and will not have any obvious symptoms.
What causes Pneumatocele?
In adults, causes include infections, trauma, and chemical pneumonitis. Most common infectious causes are Streptococcus and Staphylococcus aureus pneumonia. Traumatic causes of pneumatocele include blunt injury to the chest causing contusions an continuous positive-airway pressure in mechanical ventilation .
How many cases of pulmonary sequestration have there been in Lausanne?
In the Department of surgery at the CHUV in Lausanne, 26 cases of pulmonary sequestration were operated on between May 1959 and May 1997. There were 16 males, ten females, four children and 22 adults.
What does sequestration of the lung look like?
The sequestrated portion of the lung is usually more echogenic than the rest of the lung. On antenatal ultrasound, an extralobar sequestration may be seen as early as 16 weeks gestation and typically appears as a solid well-defined triangular echogenic mass 8.
What are the different types of pulmonary sequestration?
Two types of pulmonary sequestration are recognised, depending on whether or not the malformation possesses its own pleural covering. Intralobar sequestration is an abnormal region within the normal pulmonary parenchyma without its own pleural covering.
What is Intralobar sequestration of the lungs?
Intralobar sequestration is an abnormal region within the normal pulmonary parenchyma without its own pleural covering. Extralobar sequestration corresponds to a true accessory lung, with its own pleural envelope , , , , , , , .
