A developmental anomaly in which a mass of nonfunctioning lung tissue lacks normal connection with the tracheobroncheal tree and receives an anomalous blood supply originating from the descending thoracic or abdominal aorta. The mass may be extralobar, i.e., completely separated from normally connected lung, or intralobar, i.e., partly surrounded by normal lung.
Abnormal accumulation of serous fluid in two or more fetal compartments, such as SKIN; PLEURA; PERICARDIUM; PLACENTA; PERITONEUM; AMNIOTIC FLUID. General fetal EDEMA may be of non-immunologic origin, or of immunologic origin as in the case of ERYTHROBLASTOSIS FETALIS.
A chronic lung disease developed after OXYGEN INHALATION THERAPY or mechanical ventilation (VENTILATION, MECHANICAL) usually occurring in certain premature infants (INFANT, PREMATURE) or newborn infants with respiratory distress syndrome (RESPIRATORY DISTRESS SYNDROME, NEWBORN). Histologically, it is characterized by the unusual abnormalities of the bronchioles, such as METAPLASIA, decrease in alveolar number, and formation of CYSTS.
Hypersensitivity reaction (ALLERGIC REACTION) to fungus ASPERGILLUS in an individual with long-standing BRONCHIAL ASTHMA. It is characterized by pulmonary infiltrates, EOSINOPHILIA, elevated serum IMMUNOGLOBULIN E, and skin reactivity to Aspergillus antigen.
Blocking of the PULMONARY ARTERY or one of its branches by an EMBOLUS.
Radiography of blood vessels after injection of a contrast medium.
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.

Diagnosis of pulmonary sequestration by spiral CT angiography. (1/92)

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.  (+info)

Direct intrauterine fetal therapy in a case of bronchopulmonary sequestration associated with non-immune hydrops fetalis. (2/92)

Bronchopulmonary sequestration associated with non-immune hydrops fetalis is generally recognized as a uniformly fatal fetal condition without fetal surgical intervention. We describe here the first case of such a condition treated successfully with direct intrauterine fetal therapy using digoxin and frusemide.  (+info)

Management of antenatally diagnosed pulmonary sequestration associated with congenital cystic adenomatoid malformation. (3/92)

BACKGROUND: Sequestration with associated cystic adenomatoid malformation is rare. A study was undertaken to determine whether pulmonary sequestration associated with congenital cystic adenomatoid malformation has a more favourable natural history than that of sequestration without associated cystic adenomatoid malformation. METHODS: An outline of the postnatal work up leading to the management of extralobar or intralobar pulmonary sequestration with congenital cystic adenomatoid malformation diagnosed antenatally as pulmonary malformation is presented and the indications for surgical intervention are discussed. RESULTS: In five infants in whom an antenatal ultrasound scan had detected a congenital lung malformation at 18-19 weeks gestation a final diagnosis of extralobar or intralobar pulmonary sequestration with congenital cystic adenomatoid malformation was made postnatally. Postnatal ultrasound and computerised axial tomographic scans confirmed the diagnosis of sequestration by delineating anomalous vascular supply. Cystic changes were also observed in the basal area of the sequestration in all patients. Four children remained asymptomatic and one infant presented at 10 months of age with pneumonia. The mean age at surgical resection was 6.8 months (range 2-10). Histopathological examination confirmed intralobar pulmonary sequestration with associated Stocker type 2 congenital cystic adenomatoid malformation in two patients and extralobar pulmonary sequestration with associated Stocker type 2 congenital cystic adenomatoid malformation in three patients. The mean period of follow up was four years (range 1-8). The children remain well and are developing normally. CONCLUSIONS: The importance of seeking an anomalous blood supply in children with congenital lung lesions is emphasised. Pulmonary sequestration and congenital cystic adenomatoid malformation probably share a common embryogenesis despite diverse morphology. The natural history of antenatally diagnosed lung masses is variable. Early postnatal surgical resection of pulmonary sequestration with cystic adenomatoid malformation is recommended. Surgical excision should be conservative, sparing the normal lung parenchyma.  (+info)

A familial case of pulmonary arterial sequestration. (4/92)

The cases of a mother and infant son are reported, both with a rare type of pulmonary sequestration where the arterial supply to the lung arises from the systemic circulation. This is a familial case of arterial sequestration. In both patients, the lung parenchyma was radiologically normal.  (+info)

Primary lymphoepithelioma-like carcinoma within an intralobular pulmonary sequestration. (5/92)

A 31-yr-old Chinese female, a nonsmoker, presented with digital clubbing and coughing. Diagnostic evaluation revealed a pulmonary sequestration in the left lower lobe. During surgery a tumour was discovered, which turned out to be a lymphoepithelioma-like carcinoma. These tumours are mainly found in Asians, and are associated with the Epstein Barr virus and not with smoking. They are thought to have a better prognosis and to be more chemosensitive. The need for surgical treatment of pulmonary sequestration and the recognition of lymphoepithelioma-like carcinoma as a distinct clinicopathological entity is emphasized.  (+info)

Contrast enhanced MR angiography in pulmonary sequestration. (6/92)

OBJECTIVE: To evaluate the feasibility of contrast enhanced three-dimensional (3D) magnetic resonance angiography (MRA) in identifying the systemic blood supply in pulmonary sequestration. METHODS: Three patients who were suspected of pulmonary sequestration were examined by contrast enhanced 3D MRA. MR images were compared with surgical findings. RESULTS: Contrast enhanced 3D MRA clearly demonstrated systemic arteries from the descending thoracic aorta supplying the basilar segments of the lower lobe in each case. Pulmonary veins from these segments, which drained into the left atrium in two cases, were also detected. MRA images were consistent with those observed in surgery. CONCLUSION: Contrast enhanced 3D MRA allows accurate diagnosis of pulmonary sequestration and may obviate the need for more invasive investigations.  (+info)

Intralobar pulmonary sequestration presenting increased serum CA19-9 and CA125. (7/92)

A 39-year-old man was admitted to our hospital for further evaluation of a consolidated shadow and clarification of the cause of serum tumor marker elevation (CA19-9 496.2 U/ml, CA125 160.6 U/ml). Chest computed tomography revealed a well-defined homogeneous nodule in the left S(10). Angiography showed one aberrant artery, branching from the ascending aorta. Intralobar pulmonary sequestration was diagnosed and the sequestrated lung was resected. Microscopic findings of the sequestrated lung showed a mucus-containing cystically dilated bronchus, which was covered with ciliated cylindrical epithelium. Immunohistochemical staining showed positive staining for CA19-9 and CA125 in both the ciliated cylindrical epithelium and mucus. Serum values of tumor markers returned to their normal range after surgery.  (+info)

Pulmonary sequestration associated by Mycobacterium intracellulare infection. (8/92)

A case of a 29-year-old woman with intralobar pulmonary sequestration infected with Mycobacterium intracellulare is presented. A chest CT scan revealed a density in the posterior segment of the left lower lobe, and an acid-fast bacillus sputum culture yielded Mycobacterium intracellulare. After 3 months of treatment with clarithromycin, streptomycin, rifampicin and ethambutol, the patient underwent partial resection of the left lower lobe. At the 6-month follow-up the patient's clinical status is excellent. A review of the literature revealed only three case reports of pulmonary sequestration associated with Mycobacterium avium-intracellulare complex infection.  (+info)

Bronchopulmonary sequestration is a rare birth defect of the lungs, in which a mass of abnormal lung tissue develops that doesn't function and isn't connected to the tracheobronchial tree (the airways that lead to the lungs). This means that the abnormal tissue receives its blood supply from an anomalous systemic artery instead of the normal pulmonary circulation. The mass may be located within the lung (intralobar sequestration) or outside the lung (extralobar sequestration), and it can occur on either side of the chest.

Intralobar sequestrations are more common than extralobar sequestrations, accounting for about 75% of cases. They are usually found in adults and are located within a normal lung tissue. Extralobar sequestrations, on the other hand, are typically detected earlier in life (often as an incidental finding during prenatal ultrasound) and are surrounded by their own pleural lining, which can make them appear separate from the normal lung tissue.

Symptoms of bronchopulmonary sequestration may include recurrent respiratory infections, coughing up blood (hemoptysis), shortness of breath, or chest pain. Treatment usually involves surgical removal of the abnormal tissue to prevent complications such as infection, bleeding, or the development of malignancy.

Hydrops Fetalis is a serious condition characterized by the accumulation of excessive fluid in two or more fetal compartments, including the abdomen (ascites), around the heart (pericardial effusion), and/or within the lungs (pleural effusion). This accumulation can also affect the skin, causing it to become edematous. Hydrops Fetalis is often associated with various underlying causes, such as chromosomal abnormalities, congenital infections, genetic disorders, and structural defects that impair the fetus's ability to maintain fluid balance. In some cases, the cause may remain unknown. The prognosis for Hydrops Fetalis is generally poor, with a high mortality rate, although early detection and appropriate management can improve outcomes in certain situations.

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that primarily affects premature infants. It is defined as the need for supplemental oxygen at 28 days of life or beyond, due to abnormal development and injury to the lungs.

The condition was first described in the 1960s, following the introduction of mechanical ventilation and high concentrations of oxygen therapy for premature infants with respiratory distress syndrome (RDS). These treatments, while lifesaving, can also cause damage to the delicate lung tissue, leading to BPD.

The pathogenesis of BPD is complex and involves an interplay between genetic factors, prenatal exposures, and postnatal injury from mechanical ventilation and oxygen toxicity. Inflammation, oxidative stress, and impaired lung development contribute to the development of BPD.

Infants with BPD typically have abnormalities in their airways, alveoli (air sacs), and blood vessels in the lungs. These changes can lead to symptoms such as difficulty breathing, wheezing, coughing, and poor growth. Treatment may include oxygen therapy, bronchodilators, corticosteroids, diuretics, and other medications to support lung function and minimize complications.

The prognosis for infants with BPD varies depending on the severity of the disease and associated medical conditions. While some infants recover completely, others may have long-term respiratory problems that require ongoing management.

Allergic bronchopulmonary aspergillosis (ABPA) is a medical condition characterized by an hypersensitivity reaction to the fungus Aspergillus species, most commonly A. fumigatus. It primarily affects the airways and lung tissue. The immune system overreacts to the presence of the fungus, leading to inflammation and damage in the lungs.

The main symptoms of ABPA include wheezing, coughing, production of thick mucus, shortness of breath, and chest tightness. These symptoms are similar to those seen in asthma and other respiratory conditions. Some people with ABPA may also experience fever, weight loss, and fatigue.

Diagnosis of ABPA typically involves a combination of clinical evaluation, imaging studies (such as chest X-rays or CT scans), and laboratory tests (such as blood tests or sputum cultures) to detect the presence of Aspergillus species and elevated levels of certain antibodies.

Treatment for ABPA usually involves a combination of corticosteroids to reduce inflammation and antifungal medications to eradicate the Aspergillus infection. In some cases, immunomodulatory therapies may also be used to help regulate the immune system's response to the fungus.

It is important to note that ABPA can lead to serious complications if left untreated, including bronchiectasis (permanent enlargement of the airways), pulmonary fibrosis (scarring of the lung tissue), and respiratory failure. Therefore, prompt diagnosis and treatment are essential for managing this condition.

A pulmonary embolism (PE) is a medical condition that occurs when a blood clot, often formed in the deep veins of the legs (deep vein thrombosis), breaks off and travels to the lungs, blocking one or more pulmonary arteries. This blockage can lead to various symptoms such as shortness of breath, chest pain, rapid heart rate, and coughing up blood. In severe cases, it can cause life-threatening complications like low oxygen levels, hypotension, and even death if not promptly diagnosed and treated with anticoagulant medications or thrombolytic therapy to dissolve the clot.

Angiography is a medical procedure in which an x-ray image is taken to visualize the internal structure of blood vessels, arteries, or veins. This is done by injecting a radiopaque contrast agent (dye) into the blood vessel using a thin, flexible catheter. The dye makes the blood vessels visible on an x-ray image, allowing doctors to diagnose and treat various medical conditions such as blockages, narrowing, or malformations of the blood vessels.

There are several types of angiography, including:

* Cardiac angiography (also called coronary angiography) - used to examine the blood vessels of the heart
* Cerebral angiography - used to examine the blood vessels of the brain
* Peripheral angiography - used to examine the blood vessels in the limbs or other parts of the body.

Angiography is typically performed by a radiologist, cardiologist, or vascular surgeon in a hospital setting. It can help diagnose conditions such as coronary artery disease, aneurysms, and peripheral arterial disease, among others.

Digital subtraction angiography (DSA) is a medical imaging technique used to visualize the blood vessels and blood flow within the body. It combines the use of X-ray technology with digital image processing to produce detailed images of the vascular system.

In DSA, a contrast agent is injected into the patient's bloodstream through a catheter, which is typically inserted into an artery in the leg and guided to the area of interest using fluoroscopy. As the contrast agent flows through the blood vessels, X-ray images are taken at multiple time points.

The digital subtraction process involves taking a baseline image without contrast and then subtracting it from subsequent images taken with contrast. This allows for the removal of background structures and noise, resulting in clearer images of the blood vessels. DSA can be used to diagnose and evaluate various vascular conditions, such as aneurysms, stenosis, and tumors, and can also guide interventional procedures such as angioplasty and stenting.

The Ventilation-Perfusion (V/Q) ratio is a measure used in respiratory physiology to describe the relationship between the amount of air that enters the alveoli (ventilation) and the amount of blood that reaches the alveoli to pick up oxygen (perfusion).

In a healthy lung, these two processes are well-matched, meaning that well-ventilated areas of the lung also have good blood flow. This results in a V/Q ratio close to 1.0.

However, certain lung conditions such as emphysema or pulmonary embolism can cause ventilation and perfusion to become mismatched, leading to a V/Q ratio that is either higher (ventilation exceeds perfusion) or lower (perfusion exceeds ventilation) than normal. This mismatch can result in impaired gas exchange and lead to hypoxemia (low oxygen levels in the blood).

The V/Q ratio is often used in clinical settings to assess lung function and diagnose respiratory disorders.

Technetium Tc 99m Aggregated Albumin is a radiopharmaceutical preparation used in diagnostic imaging. It consists of radioactive technetium-99m (^99m^Tc) chemically bonded to human serum albumin, which has been aggregated to increase its size and alter its clearance from the body.

The resulting compound is injected into the patient's bloodstream, where it accumulates in the reticuloendothelial system (RES), including the liver, spleen, and bone marrow. The radioactive emission of technetium-99m can then be detected by a gamma camera, producing images that reflect the distribution and function of the RES.

This imaging technique is used to diagnose and monitor various conditions, such as liver disease, inflammation, or tumors. It provides valuable information about the patient's health status and helps guide medical decision-making.

The pulmonary artery is a large blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. It divides into two main branches, the right and left pulmonary arteries, which further divide into smaller vessels called arterioles, and then into a vast network of capillaries in the lungs where gas exchange occurs. The thin walls of these capillaries allow oxygen to diffuse into the blood and carbon dioxide to diffuse out, making the blood oxygen-rich before it is pumped back to the left side of the heart through the pulmonary veins. This process is crucial for maintaining proper oxygenation of the body's tissues and organs.

Sodium Pertechnetate Tc 99m is a radioactive pharmaceutical preparation used in medical diagnostic imaging. It is a technetium-99m radiopharmaceutical, where technetium-99m is a metastable nuclear isomer of technetium-99, which emits gamma rays and has a half-life of 6 hours. Sodium Pertechnetate Tc 99m is used as a contrast agent in various diagnostic procedures, such as imaging of the thyroid, salivary glands, or the brain, to evaluate conditions like inflammation, tumors, or abnormalities in blood flow. It is typically administered intravenously, and its short half-life ensures that the radiation exposure is limited.
