To compare outcomes and short-term complications of dogs with laryngeal paralysis treated with unilateral arytenoid lateralization performed on an outpatient versus inpatient basis.
44 client-owned dogs.
Medical records were retrospectively reviewed to identify dogs that underwent unilateral arytenoid lateralization for the treatment of laryngeal paralysis between 2018 and 2022. Signalment, surgical technique, anesthesia time, comorbidities, laryngeal examination, concurrent procedures, use of prokinetics and sedatives, episodes of vomiting, episodes of regurgitation, duration of hospitalization, postoperative complications, anxiety scores, and pain scores were recorded. Variables were compared between dogs and grouped by outpatient or inpatient management.
The overall complication rate was 22.7% (10/44), with 35% (7/20) being in the inpatient group and 12.5% (3/24) being in the outpatient group. The overall mortality rate was 6.8% (3/44). The overall morbidity for hospitalized patients versus those undergoing and outpatient procedure was 5% (1/20) and 4.2% (1/24), respectively. There was no significant difference between overall rate of complications and mortality rates between the inpatient and outpatient groups.
Results suggested that outpatient management of dogs with laryngeal paralysis treated with elective unilateral arytenoid lateralization is an appropriate method of postoperative management with no difference in complication or mortality rates. Further prospective studies with standardized surgical, sedative, and antiemetic protocols are warranted to evaluate more definitely.
To compare osteoarthritis scores assigned through radiographic evaluation of 18 anatomic regions in the elbow joint with scores assigned through evaluation of 3-D maximum intensity projection (MIP), 3-D surface rendering (TSR), and multiplanar reconstructed (MPR) CT images, and to evaluate intraobserver and interobserver agreement of radiographic and CT scoring.
Radiographic and CT images of 39 elbow joints in 20 dogs.
Images were anonymized and graded independently by 5 observers. One observer graded 12 elbow joints 3 times. Intraobserver consistency and repeatability, interobserver agreement, consistency among methods, and bias between methods were calculated.
The most severe changes were observed at the proximal aspect of the anconeal process, and the medial and cranial aspects of the medial coronoid process. Intraobserver consistency was moderate or better for 11/16 regions with MIP images, 11/16 regions with TSR images, 17/18 regions with MPR images, and 14/18 regions with radiographic images. Interobserver agreement was moderate or better for 5/16 regions with MIP images, 9/16 regions with TSR images, 12/18 regions with MPR images, and 6/18 regions with radiographic images. Mean scores from CT-based methods were higher than mean radiographic scores.
Assessments of osteoarthritis severity in the elbow joints of dogs obtained by examining radiographic images were generally consistent with assessments obtained by examining CT scans. MPR scores were more consistent and more comparable to radiographic scores than were MIP or TSR scores.
