Last check: 2007-11-06) From the vertebral column the pleura passes to the side of the pericardium, which it covers to a slight extent; it then covers the back part of the root of the lung, from the lower border of which a triangular sheet descends vertically toward the diaphragm. Above the level of the root of the lung, however, the mediastinal pleura passes uninterruptedly from the vertebral column to the sternum over the structures in the superior mediastinum. The reflection of the left pleura follows at first the ascending part of the sixth costal cartilage, and in the rest of its course is slightly lower than that of the right side. www.bartleby.com.cob-web.org:8888 /107/238.html   (951 words)

Chapter 22: The pleurae and lungs The contact between the parietal and visceral pleurae depends on the atmospheric pressure (1) on the outside of the chest wall and (2) inside the alveoli (which are connected to the exterior by the bronchial tree). The anterior border of the lung corresponds to that of the pleura, although it is uncertain whether the costomediastinal recess of the pleura is completely filled by the lung during quiet breathing, as it is in deep inspiration. The serous membranes are the pleura, pericardium, and peritoneum. www.dartmouth.edu /~humananatomy/part_4/chapter_22.html   (3017 words)

mediastinal pleura (anatomy) - General Practice Notebook   (Site not responding. Last check: 2007-11-06) Mediastinal pleura is the portion of the parietal pleural membrane that lines the mediastinum. It is bounded by and is continuous with the anterior and posterior margins of the costal pleura, the cervical pleura superiorly and the diaphragmatic pleura inferiorly. Superiorly to the lung root, the mediastinal pleura is a broad, uninterrupted sheet between sternum and vertebrae. www.gpnotebook.co.uk /cache/1657798715.htm   (165 words)

CancerNetwork: Using an endoshears with an electrocautery attachment, the pleura is incised from the level of the subclavian vessels (Figure 9). The mediastinal pleura is next incised from the azygos vein to the subcarinal region and finally to the inferior pulmonary vein. A biopsy grasper is used to elevate the mediastinal pleura overlying the lymph nodes (Figure 11), and a bipolar electrocautery probe or monopolar cautery scissors is used to incise the pleura. www.cancernetwork.com /journals/oncology/o9606a.htm   (6625 words)

MUSC Digestive Disease Center - Clinical Atlases Mediastinal staging in a patient with a left lower lobe primary tumor revealed a small malignant pleural effusion and bilateral mediastinal nodal metastases. A hypoechoic mediastinal mass is seen abutting the aortic arch (in cross-section) for a distance of 12mm (arrow). The mediastinal pleura is markedly thickened by an irregular, hypoechoic mass (arrows) and an anechoic malignant effusion is also visible. www.ddc.musc.edu /ddc_pro/pro_development/atlases/EUS/cancer2.htm   (711 words)

ACP - Delaware Chapter - Awards At surgical resection by median sternotomy, the mass was much larger than that seen on CT. It was densely adherent to the pericardium, mediastinal pleura and left lung with encasement of a portion of the left pulmonary artery. Mediastinal rhabdomysarcoma is a very rare diagnosis, sparsely reported in the literature, and often seen in association with other tumors including malignant teratoma, nonteratomatous germ cell tumor, and thymic carinosarcoma. Mediastinal rhabdomyosarcomas appear to have an aggressive course with rapid progression to death and have not been found to be responsive to current surgical and chemotherapeutic modalities. www.acponline.org /chapters/de/vandover_04.htm   (841 words)

Cecil Textbook of Medicine : /> Aspergillosis (Chapter 386) of the pleura is uncommon, but an inflammatory, thickened pleura is frequently seen in progressive invasive aspergillosis. Mediastinal invasion with lymphatic blockage and effusion is more common with Hodgkin's lymphoma (Chapter 194). It may be caused by (1) perforation of the visceral pleura and entry of gas from the lung; (2) penetration of the chest wall, diaphragm, mediastinum, or esophagus; or (3) gas generated by microorganisms in an empyema. www.merckmedicus.com /ppdocs/us/common/cecils/chapters/095_009.htm   (2768 words)

Extended VATS Thymectomy for Myasthenia Gravis Extrapleural Pneumonectomy   (Site not responding. Last check: 2007-11-06) The dissection is begun inferiorly by incising the mediastinal pleura along the anterior border of the phrenic nerve (Figure 3; videoclip). Because of the preoperative pneumomediastinum, the mediastinal adipose tissue is embedded with air and the thymus is already partially separated from the pericardium and from the sternum. Subsequently, all mediastinal fat that is found in the pretracheal space, along the internal mammary pedicles, in the aorto-pulmonary window (Figure 7; videoclip), as well as in the right (Figure 8; videoclip) or left (Figure 9; videoclip) pericardiophrenic angles that may contain ectopic thymic tissue is completely excised to accomplish an extended thymectomy (Figure 10). www.ctsnet.org /sections/clinicalresources/thoracic/expert_tech-14.html   (1861 words)

Thoracic Wall, Pleura, and Pericardium - Dissector Answers The costomediastinal recess is a smaller potential space between the layer of costal pleura and mediastinal pleura anteriorly.

Technique of right sided mediastinal The inferior pulmonary ligament is excised and the mediastinal pleura extending from the pericardium back to the spine is excised as well as the lymph nodes lying anterior to the esophagus. The upper mediastinal dissection begins with dissection, and ligation of the azygos vein anteriorly at the superior vena cava, and posteriorly. Next, two longitudinal incisions are made in the parietal pleura, the first follows the course of the vagus nerve and the second, the posterior edge of the superior vena cava. www.smokinglungs.com /mndtechr.htm   (678 words)

HTML document for the World Wide Web   (Site not responding. Last check: 2007-11-06) On CT the disorder characteristically spares the mediastinal pleura (which is often involved by mesothelioma). Approximately 80% of mesotheliomas arise from the parietal pleura and on histologic analysis the cell type is often mixed and difficult to distinguish from adenocarcinoma. In patients with Stage I disease an attempt to remove all the tumor is performed by an extrapleural pneumonectomy which consists of en block resection of the parietal and mediastinal pleura, lung, ipsilateral pericardium, and the hemidiaphragm. www.indyrad.iupui.edu /public/lectures/HTML/chest-rm/Pleura.htm   (1717 words)

Pleural Cavity and Lungs Notice that the visceral and parietal pleura are continuous at the root of the lung. Notice again that the visceral and parietal pleurae are continuous at the root of the lung. In cadaveric lung specimens, grooves are sometimes left on the mediastinal aspect of the lungs and these are formed by structures near the lung. mywebpages.comcast.net /wnor/thoraxlesson2.htm   (511 words)

Invasion Beyond Interlobar Pleura in Non-small Cell Lung Cancer - ) CHEST - Find Articles   (Site not responding. Last check: 2007-11-06) Study objective: To assess the outcome of lung cancer with invasion beyond interlobar pleura and to clarify whether it should be treated in the same way as invasion to the parietal pleura or to other visceral pleura. The TNM classification[1] proposed by Union International Contre le Cancer states that a tumor invading the visceral pleura is classified as T2 and a tumor directly invading the chest wall, diaphragm, mediastinal pleura, or parietal pericardium is classified as T3. Therefore, a total of 18 patients with invasion beyond interlobar pleura were studied clinically and pathologically and the results were compared with those of patients with parietal pleural invasion, including mediastinal pleural invasion and diaphragm, and those of patients with other visceral pleural invasion treated during the same time period. www.findarticles.com /p/articles/mi_m0984/is_5_114/ai_53378393   (794 words)

Multivesicular Mediastinal Hydatid Cyst   (Site not responding. Last check: 2007-11-06) Perhaps such an abnormal route may be the explanation for development of hydatid cyst in such unconnected tissue as breast, thyroid, bone, submandibular salivary gland and mediastinum as in the present case. Multiple cyst grow widely throughout the pleura and may invade the chest wall diaphragm and mediastinum. Hence, a unique case of isolated mediastinal hydatid cyst containing daughter cysts, without associated pleuro pulmonary hydatid disease is hereby presented. www.bhj.org /journal/2004_4602_april/html/multivesicular_191.htm   (638 words)

Respiratory Research | Full text | Spinal afferent neurons projecting to the rat lung and pleura express acid sensitive ... One study provided recordings from an in vitro preparation of rabbit phrenic nerve and mediastinal pleura and demonstrated multimodal mechano- and chemosensitive afferent units that respond to potentially tissue damaging stimuli [14]. Segmental levels C4-C6 release the phrenic nerve who contributes, besides fibres to the serosal surfaces of the diaphragm and mediastinal pleura [14], also a significant number of nerve fibres to the pericardium [39,40]. As for the parietal pleura, data are available only for the rabbit where all mechanoreceptors exhibit SAR properties, and those with fastest conduction velocity (11.0 ± 1.3 m/s) are purely mechanosensitive [15]. respiratory-research.com /content/7/1/96   (5953 words)

Transesophageal echographic determination of aortic invasion by lung cancer CHEST - Find Articles   (Site not responding. Last check: 2007-11-06) T-staging of lung cancer is mostly based on CT. However, reliable CT criteria of mediastinal tumor invasion (1-6) and the potential advantages of MRI (7,8) have not been defined. Invasion of the mediastinal pleura but not the aortic wall is recognizable by disappearance of the outer line and the pulsating movement of the vessel along the invaded pleura. Respiratory movement of the consolidated lung along the borderline proves that the mediastinal pleura is not involved. www.findarticles.com /p/articles/mi_m0984/is_2_127/ai_n11850193   (818 words)
