The two forms of pulmonary sequestration are intrapulmonary, which is surrounded by normal lung tissue, and extrapulmonary, which has its own pleural investment. (medscape.com)
Although an intrapulmonary sequestration is usually diagnosed later in childhood or adolescence, symptoms may begin early in childhood with multiple episodes of pneumonia. (medscape.com)
Computed tomography (CT) scanning with contrast and magnetic resonance angiography (MRA) are also highly useful in revealing the presence of systemic arteries, which are the major diagnostic feature of pulmonary sequestration. (medscape.com)
Intrapulmonary sequestration occurs within the visceral pleura of normal lung tissue. (medscape.com)
7] A case of intrapulmonary sequestration associated with a bronchogenic cyst has been reported. (medscape.com)
Further dissection revealed a plane between a consolidated area and the remainder of the lower lobe and it became apparent that this was an intrapulmonary sequestration. (ersjournals.com)
This lung bud may be formed within normal lung tissue and become encased with the same pleural covering (intrapulmonary sequestration) or may become completely enclosed within its own pleural sac (extrapulmonary sequestration). (ersjournals.com)
Shunt2
Intrapulmonary shunt was measured using the inert gas SF(6). (vub.be)
Pretreatment with bosentan prevented the oleic acid-induced shift of (MPAP-PAOP)/CI plots to higher pressures, but did not affect the increase in intrapulmonary shunt. (vub.be)
Haemorrhage1

Such effects are possible because the lung anatomy allows for application of drugs to the small pulmonary arteries by diffusion from alveolar surfaces. (iospress.nl)

We are also interested in the role of inducible intrapulmonary arteriovenous pathways in disease states such as cryptogenic stroke, BPD, and high altitude pulmonary edema. (wisc.edu)
Aortic1
The ALCAPA anomaly may result from (1) abnormal septation of the conotruncus into the aorta and pulmonary artery, or from (2) persistence of the pulmonary buds together with involution of the aortic buds that eventually form the coronary arteries. (medscape.com)
This is the intrapulmonary variant. (medscape.com)
