Chest X-Ray Guide, Abnormalities of Lung and Heart Diseases 1 Anterior-posterior (AP) view refers to X-ray images taken by allowing the ionizing rays to pass from front to the back of the chest where the x-ray film is placed. 2  This is the least commonly used view as the interpretation of the information in these films is difficult.

Thoracic cavity Lungs, among others removed. The thoracic cavity (or chest cavity) is the chamber of the human body (and other animal bodies) that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum.There are two openings of the thoracic cavity, a superior thoracic aperture known as the thoracic inlet and a lower inferior thoracic aperture known as the thoracic outlet.The thoracic cavity includes the tendons as well as the cardiovascular system which could be damaged from injury to the back, spine or the neck.he central compartment of the thoracic cavity is the mediastinum.

Thoracic Aortic Aneurysm The normal size for the thoracic and thoracoabdominal aorta is larger than that of the infrarenal aorta, and aneurysmal degeneration in these areas is defined accordingly. The average diameter of the mid-descending thoracic aorta is 26-28 mm, compared with 20-23 mm at the level of the celiac axis.The occurrence and expansion of an aneurysm in a given segment of the arterial tree probably involves local hemodynamic factors and factors intrinsic to the arterial segment itself.he average diameter of the mid-descending thoracic aorta is 26-28 mm, compared with 20-23 mm at the level of the celiac axis.

Body cavity The thoracic cavity is the more superior subdivision of the anterior cavity, and it is enclosed by the rib cage. The thoracic cavity contains the lungs and the heart, which is located in the mediastinum.The diaphragm forms the floor of the thoracic cavity and separates it from the more inferior abdominopelvic cavity. The superior mediastinum is a wedge-shaped cavity located between the superior regions of the two thoracic cavities. 2  The pericardial cavity within the mediastinum is located at the center of the chest below the superior mediastinum.

Superior Vena Cava Syndrome Introduction. The superior vena cava is a large vein located in the upper chest, which collects blood from the head and arms and delivers it back to the right atrium of the heart. If this vein is compressed by outside structures, or if a thrombus or clot develops within it, return blood flow to the heart is impeded.he superior vena cava is a large vein located in the upper chest, which collects blood from the head and arms and delivers it back to the right atrium of the heart.

- It is important to understand the reflections of the parietal and visceral pleura on the thoracic wall as seen from anterior, lateral, and side. Generally, the visceral pleura (lungs) are 2 ribs more superior than the parietal pleura at mid inspiration.

thoracic surgery Video-assisted thoracic surgery (VATS) is a minimally invasive surgical technique that uses a thoracic endoscope (thoracoscope) to allow the surgeon to view the chest cavity. A lung is collapsed and 3-4 small incisions, or access ports, are made to facilitate insertion of the thoracoscope and the surgical instruments.

Thoracotomy Median sternotomy provides wide access to the mediastinum and is the incision of choice for most open-heart surgery and access to the anterior mediastinum. Posterolateral thoracotomy is an incision through an intercostal space on the back, and is often widened with rib spreaders.

Thoracotomy A thoracotomy is an incision into the pleural space of the chest. It is performed by surgeons to gain access to the thoracic organs, most commonly the heart, the lungs, or the esophagus, or for access to the thoracic aorta or the anterior spine. A thoracotomy is a major surgical procedure—it is the first step in many thoracic surgeries including lobectomy or pneumonectomy for lung cancer—and as such requires general anesthesia with endotracheal tube insertion and mechanical ventilation ...

Thoracic cavity Thoracic cavity, also called chest cavity, the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity (the body’s largest hollow space) by a muscular and membranous partition, the diaphragm.

Overview Thoracic outlet syndrome is a group of disorders that occur when the blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) become compressed. This can cause pain in your shoulders and neck and numbness in your fingers.ommon causes of thoracic outlet syndrome include physical trauma from a car accident, repetitive injuries from job-or sports-related activities, certain anatomical defects (such as having an extra rib), and pregnancy.

Thoracic Outlet Syndromes Thoracic outlet syndrome refers to a group of conditions that develop when the blood vessels or nerves in the thoracic outlet become compressed. The thoracic outlet is the narrow space between your collarbone and first rib. Blood vessels, nerves, and muscles that extend from the back to the arms pass through this area. If the space in the thoracic outlet is too narrow, these structures can become compressed. The increased pressure on the blood vessels and nerves may cause pain in your shoulders, neck, and arms. It can also cause numbness or tingling in your hands. The cause of thoracic outlet syndrome isn’t always known.
