Analysis of Factors Affecting Survival in Dogs With Aortic Body Tumors

Abstract

Dogs that are diagnosed with aortic body tumors may benefit from a pericardectomy at the time of surgical biopsy.

Immunohistochemical Characteristics of Canine Aortic and Carotid Body Tumours

“…Metastasis of carotid body tumours was reported in 27% of cases by Obradovich et al (1992) and in 12% of cases by Hayes and Sass (1988). Ehrhart et al (2001) recently presented an analysis of clinical factors affecting survival in dogs with aortic body tumours. Pericardectomy was the only parameter that influenced survival time.…”

Cardiac Tumors

“…The hemodynamic consequences of cardiac tumors depend on their size and location [35,36]. Most intracardiac tumors are located in the right ventricle and may lead to an obstructive syndrome [36], resulting in weakness, syncope, or right heart failure [37].…”

Thoracoscopic pericardial window for management of pericardial effusion in 15 dogs

“…In another study of dogs with cardiac base masses there was a prolonged MST of 730 days post pericardiectomy compared to 42 days without pericardiectomy (Ehrhart et al . ). However, this prolonged survival is dependent on the type of neoplasia, as dogs with right atrial masses and suspected haemangiosarcoma do not have a significantly different survival time after pericardiectomy (Dunning et al .…”

“…In a previous study of dogs with PE without cardiac masses detected by ultrasonography, the median survival time (MST) was 1218 days for those that underwent pericardiectomy compared to 532 days for those conservatively managed (Johnson et al 2004). In another study of dogs with cardiac base masses there was a prolonged MST of 730 days post pericardiectomy compared to 42 days without pericardiectomy (Ehrhart et al 2004). However, this prolonged survival is dependent on the type of neoplasia, as dogs with right atrial masses and suspected haemangiosarcoma do not have a significantly different survival time after pericardiectomy (Dunning et al 1998).…”
