Pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax.

Heartworms (Dirofilaria immitis) are blood-borne parasites that reside in the heart or nearby large blood vessels of infected animals. Recent studies of cats with heart and respiratory diseases have found an incidence of heartworms that is far greater than previously thought. Veterinarians now strongly recommend that all cats receive year-round monthly heartworm preventives. There are excellent heartworm preventives now available for cats, making prevention of heartworm disease safe and easy.

Ultrasound uses the reflection of sound waves to generate an image of internal structures, allowing for identification of masses, pregnancy diagnosis, abnormal heart function and muscle size, abnormalities of the orbit, and abnormal appearance of abdominal organs. Ultrasound results can be analyzed in real time; however, assessment by a radiologist may take several days. Ultrasound is an invaluable tool to detect problems in a non-invasive fashion.

Fever of unknown origin is a term used for persistent fever in pets. It has many possible causes, including infection, immune-mediated disease, and cancer. Initial steps in diagnosis are history and physical exam, followed by standard screening tests, including a complete blood count, biochemistry profile, and urinalysis. Further testing may be indicated. This article outlines the typical tests.

Bladder stones are rock-like formations of minerals that develop in the urinary bladder. All stones form because of disease or inflammation in the bladder. The most common signs in cats are bloody urine and straining to urinate. X-rays (with or without contrast dyes) or ultrasound may be necessary for diagnosis. The fastest way to remove bladder stones is via a surgical procedure called a cystotomy. Special diets or passing a catheter may be successful for some bladder stones. Your veterinarian will advise you of the best course of action for your cat's situation.

Bladder stones are rock-like formations of minerals that develop in the urinary bladder. The most common signs in dogs are bloody urine and straining to urinate. Bladder stones can develop within a few weeks, or they may take months to form. Most are visible on X-rays or an ultrasonic bladder examination. There are three main treatment options for bladder stones: surgical removal, non-surgical removal by urohydropropulsion, or dietary dissolution. Prevention is possible in some cases, depending on the chemical composition of the stones.

Heartworm disease is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis. Adult heartworms may live for five to seven years and, during this time, the female produces millions of offspring called microfilaria. You can prevent your dog from getting heartworms by using a heartworm preventive.

An aortic thromboembolism (ATE) results when a blood clot is dislodged and travels through the aorta, becoming lodged in a distant location. This clot causes severely reduced blood flow to the tissues receiving blood from that section of the aorta, leading to decreased oxygen in the tissues. Aortic thromboembolism is a rare occurrence in dogs and can be associated with endocarditis, cancer, sepsis, hyperadrenocorticism, and increased protein loss through diseased kidneys. This article outlines clinical signs, treatment, monitoring, and prognosis for dogs with this condition.

Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid flows from the stomach to the esophagus. In dogs with GERD, stomach acid passes through the lower esophageal sphincter and enters the esophagus. Possible signs associated with GERD include decreased appetite, difficulty swallowing, licking the lips, change in bark, chronic cough, appearance of generalized discomfort, pacing, or restlessness at night. Gastrointestinal reflux disease is often diagnosed on the basis of endoscopy. There are a number of different treatments for GERD. Most dogs require a combination of treatments, each of which addresses the problem differently. Most dogs experience a rapid improvement in clinical signs with treatment.

An electrocardiogram, or ECG, is a test that is used to assess the heart. More specifically, an ECG records the transmission of an electrical impulse through the heart. This test is not painful and is typically performed as an outpatient procedure. Analyzing the electrical impulses produced as the heart beats can help identify a number of different abnormalities within the heart.
