Many cats show respiratory signs, but the abnormality is recognized visually or by palpation by their owner. Pectus excavatum in dogs and cats. The sternum at that point projects into the thorax, reducing the dorsoventral diameter of the thoracic cavity. Though it is not necessary to correct pectus excavatum in many situations, a ratio of the transverse to the anterioposterior diameter of greater than 3.5 is felt by many to be an indication for surgery. Pectus excavatum was found in 1 to 2 per 1000 chest X-rays. This case report aims to clinically and radiologically describe a case of feline pectus excavatum and to evaluate the treatment results. It is best seen on lateral radiographs and may be an incidental finding. Contin Educ Pract Vet 12: 341-354.

Pectus excavatum (PE) is a ventral chest wall deformity, also known as funnel chest, sunken chest, chondrosternal depression or koilosternia. Pectus carinatum (chicken breast) is a congenital abnormality that results in a laterally compressed thorax secondary to ventral displacement of the caudal aspect of the sternum; it has not been reported in animals.

The excavated chest or Pectus Excavatumis an unusual congenital anomaly of the sternum and costochondral cartilage that affects dogs and cats, with the most affected cats [1-3]. Adults can be repaired with similarly good results. Pulmonary auscultation requires practice and persistence. In pectus excavatum, the sternum and costal cartilages are deformed, resulting in a horizontal narrowing of the chest, primarily on the posterior side. Cuvantul “pectus” inseamna in latina stern iar “excavatum” înfundātura. This condition may cause no clinical signs, or it may be associated with reduced exercise tolerance and recurrent bouts of respiratory disease. The malformation can cause respiratory disease and compression of the heart, which can be life-threatening in severely affected kittens (29). The deformity can be assessed objectively by measuring the frontosagittal and vertebral indices on thoracic radiographs and by assessment of the minimum thoracic height. Pectus excavatum is also known to occur in animals, e.g. The etiology is poorly understood. These techniques are generally used in immature animals with flexible cartilage. Fonkalsrud, C.B. The first step, before surgery, is a CT (CAT scan) of your child's chest to measure the indented chest depression and see whether the heart or lungs are crowded. Pectus has also been reported associated with mucopolysaccharidosis (VII) in a cat (Schultheiss and others 2000). Presence of at least four of the following: Reduced upper to lower segment ratio or arm span to height ratio > 1.05, Wrist sign (thumb and fifth digit overlap, circling the wrist) and thumb sign (distal phalanx protrudes beyond border of clenched fist), Reduced extension at the elbows (<170 degrees), Protrusio acetabuli of any degree (ascertained on radiographs). Compend . Pectus excavatum is a condition in which a person's breastbone is sunken into his or her chest. Pectus excavatum in a cat: a case report R. Yaygingul, B. Kibar, I. Suner, A. Belge Faculty of Veterinary Medicine, Adnan Menderes University, Aydin, Turkey ABSTRACT: This case report aims to clinically and radiologically describe a case of feline pectus excavatum and to evaluate the treatment results. Pets with this condition typically like their sternum has been “pushed into” their chest. Perform auscultation in a quiet room with a calm patient. The diagnosis of pectus excavatum can be established by palpation of the thorax and by thoracic radiographs. Pectus excavatum has to be differentiated from the flat-chested kitten, or “swimmer” syndrome, where the dorsoventral flattening of the chest is secondary to the transient inability to walk. Gripp, in Encyclopedia of Respiratory Medicine, 2006. Some procedures used to treat the condition in animals have not been used in human treatments, such as the use of a cast with sutures wrapped around the sternum and the use of internal and external splints. Multiple animals in some litters have been affected, so breeding from affected or related animals is not recommended.5. Literally, Pectus excavatum is Latin for “hollowed chest,” and kittens born with the defect will have either a flat chest or one that is slightly concave in more serious cases. Family study of the. Pain is mild and complications are rare; 97% of patients experience a good to excellent result. 1 It constitutes about 90% of childhood chest wall deformities. community pe Repair is recommended for symptomatic patients who have an elevated pectus severity index. Cats with high values are more likely to have impaired ventilation or ECG changes. Pectus excavatum is a congenital malformation of the sternum and costochondral cartilages resulting in a ventral dorsal narrowing of the chest or a depression of the sternum into the chest cavity. Vets keen to see more cases and would be happy to see, assess and treat any suitable cases at a greatly subsidized cost. Pectus excavatum causes a concave aspect in the ventral portion of the animal’s thorax, which is known as “funnel chest,” while pectus carinatum produces a convex appearance and is therefore called “pigeon chest.” The etiology of these anomalies has not yet been fully elucidated, but it is assumed that there is genetic involvement. The deviation of the sternum can cause rotation and displacement of the heart as well as compression of blood vessels and lung lobes. Wheezes are abnormal continuous, musical sounds resulting from passage of air through narrowed or partially obstructed airways. However lung collapse can be a secondary symptom caused by bony deformity affecting the thorax such as pectus excavatum. Katzen sind nicht die einzige Spezies, die dieses Problem haben kann, da … Stiu, suna ca in incantatiile lui Harry Potter :). 3-11). Die Inzidenz beträgt etwa 1:300 bis 1:400 Geburten. The correction can be quite substantial and often the bar can be removed after a year without the defect returning. Whether pectus excavatum in cats is an inherited condition is not known but there is undoubtedly a genetic component. Palpate the areas between the fourth and sixth intercostal spaces on either side of the thorax for the point of maximum intensity (PMI) of the heartbeat and for cardiac thrills. In patients with severe OSA or those with obesity hypoventilation syndrome, findings suggestive of right-sided heart failure (jugular venous distension, abdominal ascites, lower-extremity edema) may be present. Evaluate the femoral pulses for quality and deficits while auscultating the heart. and Beaver (1977). Surgical correction of pectus excavatum was performed using a cylindrical external splint and U-shaped external splint. Compression of the heart and kinking of great vessels can lead to heart murmurs or cardiac arrhythmias, but concurrent congenital defects are also possible and should be ruled out before surgery. Inspiratory rates in conjunction with elevated jugular venous pressure of the neck and lower-extremity edema suggest underlying cardiac disease (i.e., congestive heart failure). Sie sind Tierärztin/Tierarzt? It is more common in cats than in dogs. An additional technique is to apply moderate pressure on either side of the chest to help decrease motion caused by panting or shivering. This is a congenital thoracic wall deformity in which the caudal sternebrae is dorsally deviated towards the vertebral column. Pectus excavatum has been sporadically reported in cats. Those associated with more severe defects are growth retardation, exercise intolerance, tachypnea, cyanosis, weight loss, and vomiting. Chest X-ray. 1. Repair of pectus excavatum is not recommended unless the patient has symptoms. Pectus excavatum is a common congenital malformation of the sternum and costochondral cartilages affecting cats, especially males. The two most common congenital defects are flat … Skeletal features associated with Marfan syndrome include chest wall abnormalities (pectus carinatum or pectus excavatum), long fingers (arachnodactyly), and hypermobile joints, kypho-scoliosis or spondylolisthesis (spinal defects), pes planus (flat feet), protrusio acetabuli (hip joint abnormalities), and an arm span to height ratio > 1.05 or reduced upper segment (pelvis to top of head) to lower segment (pelvis to floor) ratio of < 0.85 in adults. While scoliosis surgery may not result in an immediate gain in lung volume, it helps minimize the future loss of vital capacity. Die Trichterbrust tritt ebenfalls gehäuft beim Marfan-Syndrom, dem Poland-Syndrom und dem Fetalen Alkoholsyndrom auf. Ein Fortbildungsbeitrag in jedem Heft sichert Ihnen 12 ATF-Stunden pro Jahr, die Teilnahme ist online möglich. This produces a caved-in or sunken appearance of the chest.It can either be present at birth or develop after puberty. Sinus arrhythmia is considered normal and is typified by increased cardiac rate during inspiration and decreased rate during expiration. Pectus excavatum has been reported in animals, most frequently in cats (3)(4)(5)(6)(7)(8)(9) (10) (11) and dogs (6,7,12,13), but it is considered to be an uncommon abnormality. The condition results in a ventral dorsal narrowing of the chest or a depression of the sternum into the chest cavity. This can then lead to pulmonary hypertension, right sided heart failure and greatly reduced life expectancy. PAUL D. SPONSELLER, in Surgical Management of Spinal Deformities, 2009. Pectus excavatum or funnel chest is an uncommon congenital anomaly of the chest wall, characterized by the dorsal deviation of the caudal sternum and associated costal cartilages or a ventral to dorsal narrowing of the entire thorax [].This defect has been reported in both dogs and cats, and can usually be diagnosed within the first few days following birth []. Pectus Excavatum este una dintre cele mai cunoscute deformari ale toracelui afectand 1 din 300 de nasteri. Diagnosis is usually made by visual recognition and is confirmed radiographically. Siamese, Burmese, and related breeds are predisposed. These values characterize the severity of pectus excavatum in cats (Table 43-1). Auscultate the heart initially over the PMI and identify the first and second heart sounds.
