RESUMO

INTRODUCTION: There is an important morbidity associated with parotidectomy. The most commonly reported permanent complication is facial nerve injury. Methylene blue staining has been used as an intra-operative tool to improve tissue visualisation and preserve facial nerve integrity. OBJECTIVES: To describe the functionality and feasibility of the use of methylene blue for parotidectomy in dogs. MATERIALS AND METHODS: Retrospective study included seven client-owned dogs that underwent parotidectomy after injection of methylene blue from 2016 to 2019 in a referral centre. Cross-sectional imaging was used to confirm parotid gland surgical disease and for staging purposes. All dogs underwent parotid resection and removal of the parotid duct after injection of methylene blue. Methylene blue was either administered via cannulation of the parotid duct or directly injected into the abnormal gland. RESULTS: In all cases, the gland stained dark blue within seconds without any evident leakage. Complete parotid gland resection and removal of the parotid duct was achieved successfully in all dogs with a mean surgical time of 97 minutes. Subjectively, the staining was useful to identify innervation outside the coloured gland and facilitated dissection. No complications, including facial nerve injury, were recorded. CLINICAL SIGNIFICANCE: Methylene blue staining for complete parotidectomy was feasible, rapid and easy in these dogs. It can be used as an indirect facial nerve identification technique, and can therefore facilitate dissection and possibly reduce the incidence of post-operative facial nerve paralysis.

RESUMO

OBJECTIVES: To report the mortality rate within a cohort of dogs undergoing cholecystectomy and investigate the impact of intra-operative hypotension on mortality. MATERIALS AND METHODS: Clinical records at five UK referral centres were reviewed for dogs undergoing cholecystectomy. Data collected included presenting signs, pre-operative blood test results, intra-operative data including frequency and duration of hypotension and the incidence and type of post-operative complications. RESULTS: Data from 119 dogs were included. Sixteen dogs (13%) died before discharge and by 28 days after surgery the total mortality was 19 dogs (17%). Hypotension lasting over 10 minutes during general anaesthesia occurred in 65 dogs (54.6%), with a mean ± sd duration of 36.1 ± 30.0 minutes. Intra-operative hypotension or the number of hypotensive episodes did not appear to be associated with in-hospital or 28-day mortality. American Society of Anaesthesiologists grade (of fitness for surgery) was significantly associated with both in-hospital and 28-day mortality on univariable analysis, as were post-operative hypoproteinaemia, ileus and pancreatitis. However on multivariable analysis, only ileus and pancreatitis were found to significantly impact mortality. CLINICAL SIGNIFICANCE: Dogs presenting with a higher American Society of Anaesthesiologists grade appear to have a higher risk of mortality, although intra-operative hypotension did not appear to be part of this risk.

RESUMO

OBJECTIVE: Review medical records of dogs that underwent adrenalectomy without pre-operative medical management, to examine the peri-operative morbidity and mortality. DESIGN: Case series of 65 dogs. METHODS: Medical records were reviewed. Features recorded included the histologic diagnosis, intra-operative hypertension or tachycardia, requirement for cavotomy, administration of intra- and post-operative corticosteroids, performance of additional surgery and the occurrence of peri-operative complications. Dogs requiring emergency surgery were excluded. RESULTS: Of the 65 dogs, 49 had adrenocortical tumours (11 bilateral), 13 had pheochromocytomas (one bilateral) and three dogs had tumours in both adrenal glands of a different tumour type. Five dogs had caudal vena cava invasion and 33 had additional procedures performed at the same time. Mortality occurred in 1/65 dogs (1.5%; 95% CI 0.03%-8.2%), major complications were identified in 1/65 dogs (1.5%; 95% CI 0.03%-8.2%) and minor complications occurred in 10/53 dogs (15%; 95% CI 8.6%-26%). CONCLUSION: Based on the limited peri-operative complications and low mortality in this pre-operatively untreated cohort, and based on critique of the available literature, the added value afforded by pre-operative treatment is questioned. With appropriate management, adrenal tumours can be removed with few peri-operative complications and low mortality.

RESUMO

A 4-year-old female spayed Pomeranian presented for being unable to use its pelvic limbs after a fall. The dog was paraplegic with absent pelvic limb nociception and a Schiff-Sherrington posture. Radiographs and Computed tomography showed a T11-T12 luxation. Spinal stabilization was performed for pain control. Twenty-four hours following surgery the patient lost pelvic limb reflexes. Twelve hours later she lost cutaneous trunci and forelimb proprioception and had increased respiratory effort. A diagnosis of progressive myelomalacia was made and the patient was euthanized. Most cases of progressive myelomalacia in dogs are due to intervertebral disc herniation. To the authors' knowledge, myelomalacia secondary to spinal fracture has not been reported.

RESUMO

OBJECTIVE: To describe perioperative characteristics and outcomes of dogs surgically treated for intestinal intussusception. STUDY DESIGN: Multi-institutional, retrospective study. ANIMALS: One hundred fifty-three client-owned dogs with intestinal intussusception. METHODS: Dogs were included when they had undergone surgical treatment of a confirmed intestinal intussusception. Medical records were reviewed for demographics and clinical data, including surgical complications (graded 1-4). Follow-up was obtained via telephone interview with owners and referring veterinarians. RESULTS: Dogs had a median age of 10 months (range, 2-156), and the most common location for intussusception was ileocolic (66/153 [43%]). Most cases had no identifiable cause (104/155 [67%]). Intestinal resection and anastomosis (IRA) was performed in 129 of 153 (84%) dogs; enteroplication was performed in 28 of 153 (18%) dogs, including 13 with and 15 without IRA. Intraoperative complications occurred in 10 of 153 (7%) dogs, all involving intestinal damage during attempted manual reduction. The median duration of follow-up after discharge was 334 days (interquartile range, 15-990; range, 1-3302). Postoperative complications occurred in 53 of 153 (35%) dogs, including 22 of 153 (14%) with severe (grade 3 or 4) events. Diarrhea, regurgitation, and septic peritonitis were the most common postoperative complications; intussusception recurred in four of 153 (3%) dogs, all within 72 hours postoperatively. Fourteen-day postoperative mortality rate was 6%. CONCLUSION: Surgical treatment of intestinal intussusception was curative in most dogs, even when an underlying cause was not identified. Surgical complications were common, including a 14% risk of life-threatening short-term complications. CLINICAL SIGNIFICANCE: Surgical treatment of intestinal intussusception offers an excellent prognosis, but the potential life-threatening complications should be considered.

RESUMO

OBJECTIVE: To identify prognostic factors for short-term survival of dogs that experience seizures within 7 days after surgical correction of single congenital extrahepatic portosystemic shunts (cEHPSS). STUDY DESIGN: Multi-institutional retrospective study. SAMPLE POPULATION: Ninety-three client-owned dogs. METHODS: Medical records at 14 veterinary institutions were reviewed to identify dogs that underwent surgical attenuation of a single cEHPSS from January 1, 2005 through February 28, 2018 and experienced postattenuation seizures (PAS) within 7 days postoperatively. Logistic regression analysis was performed to identify factors associated with 1-month survival. Factors investigated included participating institution, signalment, shunt morphology, concurrent/historical conditions, presence of preoperative neurologic signs, presence of preoperative seizures, aspects of preoperative medical management, surgical details including method and degree of shunt attenuation, type of PAS (focal only or generalized ± focal), drugs administered as part of the treatment of PAS, and development of complications during treatment of PAS. RESULTS: Thirty (32.3%) dogs survived to 30 days. Seventy-six (81.7%) dogs experienced generalized PAS. Factors positively associated with short-term survival included having a history of preoperative seizures (P = .004) and development of focal PAS only (P = .0003). Most nonsurvivors were humanely euthanized because of uncontrolled or recurrent seizures. CONCLUSION: Dogs that experienced PAS that had a history of preoperative seizures and those that experienced focal PAS only had significantly improved short-term survival. CLINICAL SIGNIFICANCE: The results of this study provide information that will help in the counseling of owners who seek treatment for PAS after surgical correction of cEHPSS. © 2020 The American College of Veterinary Surgeons.

RESUMO

OBJECTIVE: To report the occurrence and describe the management of pubic fractures after the use of an extended transpelvic urethrostomy (TPU) to treat postprostatic intrapelvic urethral obstruction and laceration in a cat. ANIMAL: One 6-year-old domestic short-haired cat. STUDY DESIGN: Case report. METHODS: A cat was presented with urethral obstruction and laceration confirmed by positive contrast retrograde urethrography. Temporary urinary diversion was performed. An attempt was made to perform perineal urethrostomy, but the cranial location of the laceration precluded this technique. An extended TPU was performed, which required removal of 30% to 60% greater length of pelvic bone than has been previously described. RESULTS: Bilateral pubic ramus fractures occurred 1 week after surgery, from which the cat clinically improved with cage rest, and exhibited evidence of healing according to computed tomography after 8 weeks. CONCLUSION: Extended TPU used to treat postprostatic intrapelvic urethral laceration may lead to pubic fractures postoperatively. CLINICAL SIGNIFICANCE: It may be prudent to rest any cat that has had a TPU or extended TPU to reduce fracture risk.

RESUMO

OBJECTIVE: To evaluate and report the quality of the scientific literature reporting complications associated with laparoscopic and laparoscopic-assisted procedures in client-owned or healthy research dogs and to report and illustrate laparoscopic complications related to individual organ systems. STUDY DESIGN: Systematic review. ANIMALS: Client-owned or healthy research dogs. METHODS: A literature review was performed by using PubMed and CAB abstracts for English-language studies providing descriptions of complications related to laparoscopic and laparoscopic-assisted procedures in dogs. Study selection used PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Quality assessment was performed by using a MINORS (Methodological Items for Non-Randomized Studies) scoring system and a grading scale of level of evidence. Descriptive statistics were used. RESULTS: In total, 741 manuscripts were identified, with 64 manuscripts eligible for data extraction and quality assessment. The most represented organ system was the female genital tract, represented by 22 (34.4%) studies. The most commonly reported intraoperative and postoperative complications were related to abdominal entry and portal incisions, respectively. In 53 of 54 non-randomized studies, high risk of bias was found. Forty-eight (75%) studies provided level III or IV evidence. CONCLUSION: This report provides an updated review of complications related to laparoscopic and laparoscopic-assisted procedures in dogs, classified by organ system. The overall quality of evidence was low, limiting direct comparison of complication rates between studies. CLINICAL SIGNIFICANCE: There is a need for implementation of standardized criteria for defining complications, study time frames and greater numbers of high quality prospective randomized trials in veterinary laparoscopy to permit comparison of complication and conversion rates between published studies and across organ systems.

RESUMO

A 12-year-old Maltese dog was referred to the Veterinary Teaching Hospital at Konkuk University because of severe regurgitation. Radiography, ultrasonography, and computed tomography showed a mass in the thoracic esophagus. Localization of the tumor, its extraluminal nature, the positioning and involvement of the stomach, and the lack of diffuse metastasis to the lung were factors considered when developing a surgical plan. A successful surgical procedure was performed. The final diagnosis was leiomyosarcoma. Following surgery, clinical signs were significantly reduced and postoperative complications were not observed. The dog died 25 days after surgery; we suspected that the death was due to postoperative stricture. Key clinical message: Surgical approaches that prioritize maintenance of low tension on the thoracic esophagus are important to prevent arrhythmia, bradycardia, and ventricular premature complex during esophagogastric anastomosis. In dogs with a small esophageal lumen anastomosis may lead to postoperative stricture.

RESUMO

To explore the shape characteristics of ablation lesions created via laser ablation (LA), radiofrequency ablation (RFA) and microwave ablation (MWA) in canine prostates and the clinical significance of these characteristics, six adult male beagles were randomly assigned to the LA, RFA, and MWA groups. These ablations were performed with common parameters applied in clinical practice (LA, 3 W/1200 J; RFA and MWA, 30 W/120 s). One ablation lesion was created in each lobe of the prostate via the ablation technique, resulting in a total of twelve ablation lesions. Transrectal ultrasound (TRUS) was used as guidance during puncture and to monitor changes in the ablation lesions. Finally, the ablation efficacy was assessed using transrectal contrast-enhanced ultrasonography (CEUS), and the transverse diameter (TRD), anteroposterior diameter (APD) and longitudinal diameter (LD) of each ablation lesion were measured. The volume (V) and the ratio (R) value were calculated. R reflects the shape characteristic of the ablation lesion (the R value close to 1.0 indicates a more spherical shape). The R values of the ablation lesions were 0.89 ± 0.02, 0.72 ± 0.01, and 0.65 ± 0.03 for RFA, MWA and LA, respectively, and they were significantly different (P = 0.027). The volumes of the ablation lesions were 2.17 ± 0.10 ml, 1.51 ± 0.20 ml, and 0.79 ± 0.07 ml for MWA, LA and RFA, respectively, and they were also significantly different (P = 0.001). The three abovementioned thermal ablation techniques with common parameters in clinical practice can be used for ablation in the prostate. The shapes and volumes of the ablation lesions of the three techniques were varied: The RFA-created lesions had the lowest volumes and were more spherical in shape, demonstrating that RFA could be used for the treatment of relatively small lesions or tumours adjacent to vital organs. The MWA lesions had the largest size with a spherical shape, which could be advantageous for the ablation of tumours with relatively large sizes. The sizes of the ablation lesions created via LA were between those of RFA and MWA but presented more oval in shape, suggesting that this method is highly appropriate for the ablation of benign prostatic hyperplasia (BPH).

RESUMO

OBJECTIVE: To describe median manubriotomy to access the ventral aspect of the caudal cervical and cranial thoracic spine and report the outcomes in dogs with lesions affecting the spinal cord at C6-T2 vertebral bodies. To evaluate possible complications of this technique and clinical outcomes. STUDY DESIGN: Cadaveric study and short case series. STUDY POPULATION: Two cadavers and nine dogs with lesions affecting the spinal cord at C6, C7, T1 or T2 vertebral bodies or corresponding intervertebral spaces. METHODS: Two cadavers were used for demonstration purposes. Medical records (2013-2019) were reviewed for dogs undergoing median manubriotomy to facilitate access to the ventral aspect of C6-T2 vertebral bodies and/or corresponding intervertebral disc spaces. Data on preoperative and postoperative neurological status and diagnostic imaging, surgical technique, and complications were retrieved. RESULTS: Indications for surgery included C7-T1 disc extrusions in five dogs, caudal cervical misalignment in three dogs, and C7-T1 and T1-T2 disc protrusions in one dog. The vertebral bodies of C6 to T2 were consistently visualized after median manubriotomy. Preoperative clinical signs resolved in five dogs and improved in two dogs. One dog was euthanized for lack of improvement, and one dog died of pulmonary thromboembolism. CONCLUSION: Median manubriotomy improved the surgical access to the ventral aspect of caudal cervical and cranial thoracic spine without related complications. CLINICAL SIGNIFICANCE: Median manubriotomy can be considered in dogs undergoing ventral decompression and/or stabilization of C7-T1 and T1-T2 intervertebral disc spaces.

RESUMO

OBJECTIVE: To report outcomes of dogs treated for lung lobe torsion (LLT) and to determine prognostic factors for survival. STUDY DESIGN: Retrospective multicenter study from four veterinary teaching hospitals. ANIMALS: Dogs (n = 80) with LLT. METHODS: Medical records were reviewed for clinical and histopathological findings. Long-term outcome was assessed with an owner questionnaire. Lung lobe torsion was classified as idiopathic or secondary on the basis of the etiology. RESULTS: The most represented breeds were pugs (47.5%) and sighthounds (16.2%). The cause of the LLT was considered primary in 77%, secondary in 21%, and unknown in 2% of dogs. Postoperative complications were recorded in 14% of dogs. Overall, 95% of dogs survived to discharge, and median follow-up was 1095 days (range, 7-3809). Owners assessed outcomes and quality of life as excellent in 93% and 89% of dogs, respectively. Primary LLT was associated with a longer survival (median not reached in the study) compared with secondary LLT (921 days; range, 7-2073; P = .001). CONCLUSION: Overall long-term survival after lung lobectomy for LLT was excellent. Primary LLT was associated with longer survival compared with secondary LLT. Long-term owner evaluation of clinical outcome for dogs undergoing lung lobectomy for LLT was considered excellent. CLINICAL IMPACT: Dogs with primary LLT undergoing lung lobectomy have a longer survival time compared with dogs with secondary LLT and have an excellent postoperative outcome.

RESUMO

OBJECTIVE: To evaluate the efficacy of various treatments for dysphagia after laryngeal surgery. STUDY DESIGN: Retrospective. ANIMALS: Horses treated for dysphagia after laryngeal surgery. METHODS: Medical records of horses treated for dysphagia after prosthetic laryngoplasty (PLP) or partial arytenoidectomy (PA) were reviewed. Signalment, prior surgery, preoperative videoendoscopic diagnosis, and surgical treatments were recorded. Short- and long-term follow-up were obtained. Chi-square and logistical regression were performed to correlate independent variables and outcomes. RESULTS: Forty-four percent of horses with prior PLP and 88% of horses with prior PA had persistent resting dorsal displacement of the soft palate (DDSP). Vocal fold augmentation (VFA) as a single treatment was most commonly performed (n = 22), followed by laryngoplasty removal (LPR; n = 1). Fifteen horses received a combination of treatments: VFA (n = 15), LPR (n = 4), laryngeal tie-forward (LTF; n = 2), and esophageal release (n = 1). Short-term clinical outcomes were reported; 80% of horses treated with VFA (n = 35) had resolution of dysphagia, and 20% were improved. Among the 33 horses available to long-term follow-up, 31 (94%) returned to some level of work, and DDSP during work was reportedly resolved in 23 of 25 horses. CONCLUSION: Vocal fold augmentation resulted in resolution of symptoms relating to dysphagia in 81% of horses. Twenty percent of horses treated with LPR had sustained resolution of dysphagia. A combination of LPR, VFA, LTF was performed in 18% of horses. CLINICAL SIGNIFICANCE: Treatment options directed at altering laryngeal geometry and/or position of the larynx were successful in resolving 86% of dysphagia in horses previously regarded as very difficult to treat.

RESUMO

OBJECTIVE: To describe a resection technique of the alar folds in the standing horse. STUDY DESIGN: Retrospective case study. ANIMALS: Eight Standardbred racing trotters. METHODS: Horses in which alar fold collapse had been diagnosed between 2017 and 2018 were included in this study. All horses underwent alar fold resection under standing sedation and regional anesthesia with a bipolar electrosurgical open sealer/divider device (LigaSure). Intraoperative and postoperative complications were recorded. A Wilcoxon signed-rank test was used to compare differences in median prize money earning pre-surgery and post-surgery (P < .05). RESULTS: The surgical procedure was short (20-30 min), with minimal (1/8) to no (7/8) bleeding and was well tolerated in all cases. Complete resection of the alar folds along with 3 to 5 cm of the ventral conchal cartilage was achieved. No complications were observed post-surgery with satisfactory second intention healing, allowing return to training/racing within 3 to 6 weeks post-surgery in all cases. Median earnings post-surgery increased (P = .03) compared with pre-surgery. CONCLUSION: Alar fold resection with bipolar electrosurgical energy offered a good alternative to the traditional surgical approaches performed under general anesthesia. The surgery significantly improved race earnings and performance while avoiding the risk associated with general anesthesia and offered a short and complication-free rehabilitation period. CLINICAL IMPACT: This study describes a surgical technique offering a novel approach to resection of the alar folds in the standing horse.

RESUMO

Background: Few reports of post-surgical evisceration, with or without autocannibalism, in dogs exist. Aims: To collect a large case series of dogs experiencing post-surgical evisceration, with or without autocannibalism. Methods: We surveyed practicing veterinarians who were members of the Veterinary Information Network about their experiences with post-surgical evisceration in dogs, variably accompanied by autocannibalism (ingestion of eviscerated organs or tissues). Responses were analyzed using descriptive statistics. Results: We identified 333 cases with sufficient information for analysis: 221 with evisceration and autocannibalism, and 112 with just evisceration. Most cases occurred following surgery for reproductive reasons (desexing, cesarean section, and pyometra). Most occurred in young adult or adult dogs. Most dogs received analgesia perioperatively had routine closure (simple interrupted or simple continuous muscle layer closure) and most did not wear an E-collar post-surgically. Most dogs eviscerated within 3 days of the initial surgery. Approximately 64% underwent surgical repair and survived long-term without complications, more frequently if the evisceration was not accompanied by autocannibalism. Conclusion: Our study suggests that post-surgical evisceration and autocannibalism can generally be successfully managed by practitioners and do not confer a uniformly poor outcome for the dog.

RESUMO

OBJECTIVES: To report results of surgical excision and Penrose drainage for the treatment of elbow hygromas in dogs. MATERIALS AND METHODS: Retrospective review of the clinical records of 19 dogs with elbow hygromas treated with Penrose drainage or surgical excision between 1997 and 2014. The data retrieved from the records included breed, gender, age, duration of clinical signs, weight, historical data, complete blood count and serum biochemistry, physical examination findings, diameter of the hygroma, cytology of needle aspirates, method of treatment, histological findings, postsurgical complications and their management and outcome. RESULTS: Twenty-one hygromas were treated in 19 dogs. Eleven were right-sided, six were left-sided and four were bilateral. First-line treatment was Penrose drain placement in 12 and complete surgical excision in nine. Bilateral hygromas were addressed simultaneously. Four of the 12 hygromas managed with Penrose drain recurred and one developed ulceration over the olecranon. Recurrent hygromas were treated by surgical excision. The ulceration was surgically excised and reconstructed with a thoracodorsal axial pattern flap. No further complications developed. All the dogs were clinically healthy after a median follow-up of 16 months. CLINICAL SIGNIFICANCE: Surgical excision of canine elbow hygroma is an effective technique that appears to have fewer postoperative complications than Penrose drain placement.

RESUMO

OBJECTIVES: To report surgical technique, intra- and post-operative complications, and short- and long-term outcome following canine hepatobiliary surgery in which exposure of intra-abdominal hepatobiliary lesions was aided by diaphragmotomy. MATERIALS AND METHODS: Clinical records from four multi-disciplinary UK-based small animal referral hospitals were retrospectively reviewed for dogs in which diaphragmotomy was performed between January 2014 and May 2019. Signalment, diagnosis, surgery performed, diaphragmotomy technique, management of diaphragmotomy and pneumothorax, intra- and post-operative complications, short-term outcome and long-term outcome were recorded. RESULTS: Thirty-one cases were identified. The most common hepatobiliary surgeries performed alongside diaphragmotomy were single hepatic lobectomy (14/31) and cholecystectomy (11/31). The most common diagnoses were hepatocellular carcinoma (10/31), gall bladder mucocoele (7/31) and hepatic nodular hyperplasia (4/31). Peri-operative mortality rate was 9.7% (3/31 cases) though none of these deaths were considered attributable to diaphragmotomy. Post-operative complications were encountered in 67.9% (19/28) cases that survived the peri-operative period, of which 25.0% (7/28) suffered complications that were considered attributable or likely attributable to diaphragmotomy. These seven complications resolved following non-surgical intervention. Follow-up was available for 26 of 28 patients that survived to discharge at a median of 4-months (range 10 days to 24 months) following surgery and revealed no evidence of complications related to diaphragmotomy. CLINICAL SIGNIFICANCE: Diaphragmotomy appears safe and increases abdominal exposure of hepatobiliary lesions. The benefit of improved exposure must be carefully weighed up against the risks inherent in inducing pneumothorax.

RESUMO

Castration of pet pigs is becoming a commonly performed procedure. However, little information is available regarding surgical techniques and complications. Medical records of 106 pet pigs admitted to 3 teaching hospitals for castration were reviewed. All descended testicles were approached via pre-scrotal skin incisions, which were either closed (59.4%) or left open (22.6%). The inguinal rings were closed in 42% of cases. Of the 106 pet pigs, 4.7% developed a complication after surgery, which consisted of peri-incisional swelling. Pigs which underwent inguinal ring closure were 6.6 times more likely to develop a post-operative complication (confidence interval: 1.16 to infinity, P = 0.035). Age and weight at time of castration were not significantly associated with complications (P = 0.698 and P = 0.685, respectively). The results from this retrospective study suggest that castration in pet pigs is a safe procedure with a minimal rate of complications.

RESUMO

OBJECTIVE: As ownership of brachycephalic dog breeds rises, the surgical correction of components of brachycephalic airway syndrome (BAS) is increasingly recommended by veterinarians. This study's objective was to describe the incidence of, and strategies for the management of post-operative respiratory complications in brachycephalic dogs undergoing surgical correction of one or more components of BAS. METHODS: Medical records of 248 brachycephalic dogs treated surgically for BAS were retrospectively reviewed for demographic information, procedures performed, post-operative complications and treatment implemented, hospitalisation time, and necessity for further surgery. RESULTS: Pugs, Cavalier King Charles Spaniels and British Bulldogs were the most commonly encountered breeds. Dogs which experienced a complication were significantly older (mean was 5.5 years, compared with 4.1 years [P < 0.01]). Fifty-eight dogs (23.4%) had complications which included: dyspnoea managed with supplemental oxygen alone (7.3%, n = 18), dyspnoea requiring anaesthesia and re-intubation (8.9%, n = 22), dyspnoea necessitating treatment with a temporary tracheostomy (8.9%, n = 22), aspiration pneumonia (4%, n = 10), and respiratory or cardiac arrest (2.4%, n = 6). Five of the 22 dogs requiring anaesthesia and re-intubation deteriorated 12 or more hours after post-surgical anaesthetic recovery. The overall mortality rate in this study was 2.4% (n = 6). Age, concurrent airway pathology, and emergency presentation significantly predicted post-operative complications. CONCLUSION: Our data show the importance of close monitoring for a minimum of 24 h following surgery by an experienced veterinarian or veterinary technician. Surgical intervention for BAS symptomatic dogs should be considered at an earlier age as an elective procedure, to reduce the risk of post-operative complications.
