hemangioquickfacts

43% of dogs with splenic masses have hemangiosarcoma (HSA)

50% of dogs with splenic HSA are in DIC (disseminated intravascular coagulation or inability to clot blood) at presentation

Average post-splenectomy survival times reported are 49-90 days

Liver biopsy is essential to differentiate between liver metastasis (spread) and benign hyperplasia (increased tissue growth)

Shepherds and northern breeds are at increased risk for developing HSA

Stage I cutaneous HSA can be cured with aggressive surgical resection

X-rays of the lungs are required to rule out pulmonary metastasis (tumors in the lungs)

Cardiac HSA is the most common cause of pericardial effusion (fluid surrounding the heart) in dogs

HSA in cats is rare but occurs most commonly within the abdomen or subcutaneous tissue (under the skin)
