A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space) between them. [1]
Hemangiosarcoma is a rapidly growing, highly invasive variety of cancer that occurs almost exclusively in dogs, and only rarely in cats, horses, mice, [ 1 ] or humans (vinyl chloride toxicity). It is a sarcoma arising from the lining of blood vessels; that is, blood-filled channels and spaces are commonly observed microscopically.
Hemopericardium is a condition that affects the cardiovascular system. It typically begins with blood accumulating in the pericardial sac posterior to the heart, and eventually expands to surround the entire heart. [6] The fluid build-up then causes pressure within the pericardial sac to increase. If the pressure becomes greater than the ...
ICD-9-CM. 37.31. MeSH. D010492. [edit on Wikidata] Pericardiectomy is the surgical removal of part or most of the pericardium. [1][2] This operation is most commonly used to relieve constrictive pericarditis, or to remove a pericardium that is calcified and fibrous. [2] It may also be used for severe or recurrent cases of pericardial effusion. [3]
Space infections: Pretracheal space – lies anterior to trachea. Pretracheal space infection leads to mediastinitis. Here, the fascia fuses with the pericardium and the parietal pleura, which explains the occurrence of empyema and pericardial effusion in mediastinitis. However, infectious of other spaces can also lead to mediastinitis.
Uremic pericarditis is associated with azotemia, and occurs in about 6-10% of kidney failure patients. BUN is normally >60 mg/dL (normal is 7–20 mg/dL). However, the degree of pericarditis does not correlate with the degree of serum BUN or creatinine elevation. The pathogenesis is poorly understood. [2]
