1/38. diagnosis of pulmonary sequestration by spiral CT angiography.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.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/38. Preoperative diagnosis of extralobar pulmonary sequestration with unusual vasculature: a case report.Pulmonary sequestrations are uncommon congenital malformations of the lung. Vascular supply to pulmonary sequestrations is variable, with many unusual combinations. Adequate preoperative evaluation is hence advisable to avoid intraoperative complications. magnetic resonance imaging (MRI) allows accurate diagnosis of extralobar pulmonary sequestration (ELPS), including definition of vascular supply. This may obviate the need for more invasive investigations that were suggested in the past. Presented here is a case of ELPS with its vascular attachments to the intercostal vessels.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
3/38. Pulmonary sequestration diagnosed by contrast enhanced three-dimensional MR angiography.Pulmonary sequestration is a congenital bronchopulmonary foregut malformation in which a segment of lung parenchyma is not connected to the tracheobronchial tree. This abnormal segment receives a blood supply from the systemic circulation. Multiple imaging modalities have been used to demonstrate the vascular anatomy of the sequestration. Different magnetic resonance angiography (MRA) techniques have been employed in the identification of these anomalous vessels. We report a case of pulmonary sequestration diagnosed by MRI with the use of contrast enhanced three-dimensional MRA.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
4/38. Pulmonary sequestration with myocardial ischemia caused by vasospasm and steal.We describe patient with a rare pulmonary sequestration with myocardial ischemia in the left coronary artery caused by vasospastic angina and stealing from coronary circulation. The anterior atrial branch from the left circumflex artery gave rise to a large and anomalous vessel in the right posterior lung field. Both the surgical and medical treatment of this pulmonary sequestration improved the control of angina attacks.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
5/38. Intralobar bronchopulmonary sequestration evaluated by contrast-enhanced three-dimensional MR angiography.bronchopulmonary sequestration (PS) is characterized by non-functioning lung tissue fed from one or several aberrant systemic arteries. The condition is diagnosed by visualizing the feeding arteries using non-invasive CT, MRI, colour Doppler sonography or conventional angiography. We present a 5-year-old boy in whom intralobar sequestration was diagnosed using contrast-enhanced 3D MR angiography, which visualised fine blood vessels in the thoraco-abdominal region without arterial puncture. This technique is useful for diagnosing PS.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
6/38. Congenital fistula between an aberrant systemic artery and a pulmonary vein without sequestration. A report of three cases.Three children had an arteriovenous fistula between an aberrant vessel from the descending aorta and a normal pulmonary vein in the posterior basal segment of a lung. The affected lung was otherwise normally developed. Only a few similar cases could be found in the literature.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
7/38. Upper thoracic extralobar pulmonary sequestration with anomalous blood supply from the subclavian artery.The authors report on a newborn boy with extralobar pulmonary sequestration in the right upper thoracic region. Preoperative angiography showed an anomalous large vessel from the right subclavian artery, supplying the sequestrated lobe. Right thoracotomy was performed to resect the sequestrated lobe, which was diagnosed as extralobar form. This is an extremely rare case of extralobar pulmonary sequestration in which anomalous blood supply from the subclavian artery was seen preoperatively on radiographs. The authors recommend angiographic examination, particularly in case of diagnostic difficulty.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
8/38. diagnosis of intralobar lung sequestration by colour-coded Doppler sonography.Intralobar lung sequestration in a 5-month-old dyspnoeic infant was diagnosed by colour-coded Doppler sonography (CDS). Grey scale imaging showed an echogenic mass adjacent to the right hemidiaphragm. CDS demonstrated an abnormal arterial blood supply via a vessel originating from the descending aorta at the level of the diaphragm.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
9/38. A rare intrapericardial mass in a neonate.We describe a rare case of a neonate born with an intrapericardial mass composed of extralobar pulmonary sequestration and a cyst of bronchogenic origin. After an uneventful delivery, this full-term newborn was noted to be grunting and indrawing. He remained tachypneic despite adequate management for bilateral pneumothoraces. Diagnostic studies showed a 3 x 3 x 4 cm diameter cystic lesion in the anterior mediastinum causing posterior-lateral displacement of the superior vena cava. The heart itself was structurally normal. bronchoscopy and esophagoscopy failed to detect any structural abnormalities. At 3 weeks of age, sternotomy and resection of the lesion was performed. The mass was clearly intrapericardial and consisted of sequestrated pulmonary tissue with a unilocular mucus filled bronchogenic cyst. Small systemic tributaries fed the lesion from the posterior-superior aspect. There was no connection with the heart or great vessels. Postoperative recovery was uneventful.- - - - - - - - - - ranking = 0.33333333333333keywords = vessel (Clic here for more details about this article) |
10/38. lung sequestration. diagnosis with ultrasound and triplex Doppler technique in an adult.The application of chest US with triplex Doppler technique to detect the systemic feeding artery of lung sequestration in an adult patient is described. To our best knowledge, this is the first description of the use of this technique to diagnose pulmonary sequestration in adult patients. This 35-year-old man had necrotizing pneumonia with abscess formation at the left lower lobe. Chest US demonstrated a large tortuous vessel in the central part of the lesion. Spectral wave Doppler analysis showed that this vessel was a systemic feeding artery and had pulsatile arterial wave-form. The color Doppler mapping delineated the blood flow originating from the descending aorta and toward the lesion, thus confirming the diagnosis of pulmonary sequestration. We conclude that chest US with triplex Doppler technique is a valuable method in evaluating a patient with a pulmonary lesion who was thought to have lung sequestration before performing invasive aortography.- - - - - - - - - - ranking = 0.66666666666667keywords = vessel (Clic here for more details about this article) |
