Abstract

OBJECTIVE:

To evaluate the clinical usefulness of the diaphragmatico-hepatic (DH) view of the abdominal and thoracic focused assessment with sonography for triage (AFAST/TFAST) in detecting pericardial effusion (PE) in dogs.

DESIGN:

Retrospective case series from 2011 to 2012.

SETTING:

Private practice emergency and critical care hospital.

ANIMALS:

Twenty-four dogs with PE diagnosed by FAST.

INTERVENTIONS:

None.

MEASUREMENT AND MAIN RESULTS:

Fifty-two medical records from October 1, 2011 through September 30, 2012 had the terms "PE" within the medical record. Twenty-four dogs were diagnosed with PE by FAST with entries for the DH view. Of the 24 dogs, 7 had abdominal FAST, 6 had thoracic FAST (TFAST), and 11 had both exams performed. PE was noted on the DH view in 20 of 24 (83%) cases. Subjective PE volume assessment ranged from trivial (<5 mm) to severe. Of the 4 cases in which PE was absent via the DH view, PE was seen during the same exam at the TFAST pericardial views (n = 2) or detected on serial exam at the DH view (n = 2). The PE volume that was missed via the DH view was characterized as trivial (<5 mm; n = 1), mild (n = 1), and moderate (n = 2).

CONCLUSIONS:

The DH view of FAST was found to be clinically helpful for the detection of PE. Veterinarians should make it routine practice and part of FAST training to look into the thorax via the DH view during both abdominal FAST and TFAST exams.
