Relative to the total number of feline patients, the disease is rare, but relatively common in cats with heart disease: about one-sixth of cats with heart disease are affected. Heart disease is the most common underlying cause of arterial thromboembolism.
Tumors and inhaled objects (possible if bedding contains loose fluff) can also cause obstruction or irritation of the airway, leading to lung collapse and secondary atelectasis. In an older cat the intercostal muscles are so well developed, and the ribs rigid enough that the ribcage will not flatten if the lung collapses: in kittens the bones ...
Feline disease refers to infections or illnesses that affect cats. They may cause symptoms, sickness or the death of the animal. Some diseases are symptomatic in one cat but asymptomatic in others. Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses.
Atelectasis. May have no signs and symptoms or they may include: [3] cough, but not prominent; chest pain (not common); breathing difficulty (fast and shallow); low oxygen saturation; pleural effusion (transudate type); cyanosis (late sign); increased heart rate. It is a common misconception and pure speculation that atelectasis causes fever.
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
Congestive heart failure can occur during later stages of the disease. [1] A 1990 study reported 50% of cats diagnosed with hypersomatotropism had developed renal failure within 8-36 months of initial examination; [2] however, another study from 2007 found a 12% incidence of azotaemia. [3]
The erythrocytic disease is not as important for clinical disease, but is often used to diagnose C. felis because piroplasms (erythrocytes that have phagocytized merozoites) can be seen on a peripheral blood smear under the microscope. [4] It is not clear why some cats become clinically affected with C. felis while others
Overdistension of alveoli and cyclic atelectasis (atelectotrauma) are the primary causes for alveolar injury during positive pressure mechanical ventilation.Severe injury to alveoli causes swelling of the tissues (edema) in the lungs, bleeding of the alveoli, loss of surfactant (decrease in lung compliance) and complete alveoli collapse ().
