What is lung lobe torsion?
Lung lobe torsion is a rare pulmonary disorder in small animals and in humans. Torsion occurs when the lung lobe rotates around the bronchus and vascular supply and remains in that position. Lung lobe torsion is a life-threatening condition.
How many lung lobes do cats have?
The right lung is formed by four lobes (cranial, middle, caudal and accessory) and the left lung by two (cranial, which is subdivided, and caudal).
What is lung lobe?
The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes. Only the right lung has a middle lobe.
What is atelectasis in cats?
Compression atelectasis: Collapse of normal alveoli. Most severe in ventral airspaces, which normally have smaller alveoli. Often caused by pressure on the chest wall from obesity or tight bandages; or pressure forward on the diaphragm from an enlarged liver, abdominal effusion or mass.
What causes lung lobe torsion in cats?
Causes. Lung lobe torsion is inconsistently found with pre-existing conditions such as trauma, neoplasia, and chylothorax. However it also occurs spontaneously, due to a thoracic or diaphragmatic surgery, or, on occasion, due to an unknown cause (idiopathic).
What causes a twisted lung?
Lung lobe torsion can be spontaneous or as a result of chylothorax, trauma, neoplasia, chronic respiratory disease or previous thoracic surgery. It is speculated that partial collapse of a lung lobe leads to an increased mobility. Most torsions result in obstruction of the venous/lymphatic supply and bronchus.
Which lung has 4 lobes?
Right lung
Right lung with four lobes and three fissures. Right lung with two lobes and one fissure. Visible artery in the fissure. Oblique fissure extending on to the base.
Why does the left lung have 2 lobes?
The left lung has only two formal lobes because of the space taken up in the left side of the chest cavity by the heart, though it does have the lingula, which is similar to a lobe.
Can a cat survive with a collapsed lung?
While pneumothorax is a very serious condition, it is important to note that with advances in diagnostic and treatment options, these cats can often be treated for a very successful outcome.
Can a cat recover from fluid around the lungs?
Cats that have progressed to a severely form of pulmonary edema tend to have a poor prognosis. However, mild to moderately ill patients stand a good chance of full recovery, and the long-term prognosis is excellent for recovered patients.
Can coughing cause collapsed lung?
Atelectasis has many causes. Any condition that makes it hard to take deep breaths or cough can lead to a collapse in the lung. People may call atelectasis or other conditions a “collapsed lung.” Another condition that commonly causes a collapsed lung is pneumothorax.
Which lung is larger right or left?
The lungs are the major organs of the respiratory system, and are divided into sections, or lobes. The right lung has three lobes and is slightly larger than the left lung, which has two lobes.
Why does the right lung have 3 lobes and the left has 2?
The oblique fissure in the left lung separates the superior and the inferior lobe. The oblique and horizontal fissure divides the lungs into superior, middle and inferior lobes. Thus the right lung has three lobes while the left has two.
How many lung lobes can be removed?
Lobectomy – A lobectomy is removal of one or two lobes of the lung. It can be done if the cancer cells are confined to just one or two lobes. Pneumonectomy – A pneumonectomy is removal of one entire lung if two lobes on the left or three lobes on the right are affected by cancer cells.
How do they remove a lung lobe?
A cut (incision) will be made on the front of your chest at the level of the lobe to be removed. The cut will go under your arm around to your back. When the ribs can be seen, a special tool will be used to spread them apart. The lung lobe will be removed.
