The perineal, scrotal, and prescrotal skin was sharply dissected from cadavers and radiographed. Angiograms were subjectively reviewed by 3 investigators.\u0000\u0000\u0000RESULTS\u0000Angiograms were completed successfully in all 10 dogs, with no difference between frozen and fresh cadavers. The dominant blood supply to the scrotum was consistently identified as arising from the ventral perineal arteries, originating from the internal pudendal arteries, coursing ventrally and cranially toward the caudal scrotum before terminating as the dorsal scrotal arteries (n = 7). The blood supply to the cranial scrotum was more limited (n = 3) as only the cranial border of the scrotum was perfused by the ventral scrotal arteries.\u0000\u0000\u0000CONCLUSION\u0000Based on this anatomic perfusion study, the dorsal scrotal arteries appear to supply a larger area than the ventral scrotal arteries.\u0000\u0000\u0000CLINICAL SIGNIFICANCE\u0000These results provide evidence to justify further consideration of a scrotal flap using the caudal perineal skin as the main cutaneous pedicle to reconstruct defects located on the caudal, medial, and lateral thighs in dogs.

An airborne particle measuring device measured and recorded baseline and intraoperative particles per cm3 (ppc) during the approach to the proximal tibia during which electrosurgery was used to provide hemostasis, dissect subcutis, transect and elevate fascia. The mean ppc, maximum ppc, and baseline ppc were compared between groups.

The procedure was completed with the SPAS alone in two cases. An additional cannula was added in 12 cases. In the last 10 cases, the additional cannula was placed at the beginning of the procedure. Dissection began at the cystic duct in 11 dogs (73%). In three cases (20%), the SPAS procedure was converted to a laparotomy; two of these conversions were elective, and one was emergent. The risk of conversion was affected by the experience of the surgeon (odds ratio = 0.53; P = .0105), and the rate of conversion was reduced when a cannula was added at the beginning of the procedure (P = .022).

Advancement of a left-sided Robertshaw double-lumen endobronchial tube (DLT) and the EZ-blocker (EZ) were evaluated under direct fluoroscopic guidance. Each dog also underwent bronchoscopy-assisted placement of an Arndt endobronchial blocker (EBB). Time to initial placement, success of creating complete OLV (after initial placement attempt and after up to two repositionings), and ease of placement score were recorded. Device position was evaluated bronchoscopically after each fluoroscopy-assisted placement attempt.\u0000\u0000\u0000RESULTS\u0000Time to initial placement was significantly shorter for EZ than for DLT and EBB. The rate of successful placement after up to two repositioning attempts was 87.5%, 87.5%, and 100.0% on the right and 87.5%, 100.0%, 100.0% on the left for DLT, EZ, and EBB, respectively, and was not different between devices.

Twenty-eight of 77 (36%) residents have access to a simulator, with box simulators being most common. Lack of time was the most frequent reason for not using the simulator more. Sixty-eight of 77 (88%) and 65 of 77 (65%) residents agreed or strongly agreed that simulator-based training improves laparoscopic skills and that simulator skills are transferable to the operating room, respectively.

A craniodorsal bladder mass was identified by computed tomography (CT), and partial cystectomy was performed with 1-cm gross lateral margins (day 1). Results of histopathology provided evidence for a diagnosis of TCC, and the dog was treated with adjuvant mitoxantrone. The dog presented with uroperitoneum on day 67 after recurrence and spontaneous perforation. Total cystectomy and ureterourethral anastomosis were performed. Ureteral obstruction developed after removal of catheters that had been placed intraoperatively. Surgical revision included resection of the anastomosis site, bilateral ureteral stenting, and transection and reorientation of the distal urethra to facilitate tension-free closure. Postoperative leakage was managed with bilateral percutaneous nephrostomy tube placement.\u0000\u0000\u0000RESULTS\u0000The dog was discharged on day 88.

Cross-sectional areas of tongue, oropharynx, nasopharynx, and palatal soft tissue were evaluated at two levels, the caudal aspect of the hard palate and the level of the hamulae of the pterygoid.

All variables were compared between brachycephalic and mesaticephalic dogs (P ≤ .05).\u0000\u0000\u0000RESULTS\u0000Absolute tongue volumes did not differ between groups, the volume of the tongue was greater in brachycephalic dogs than in mesaticephalic dogs when expressed relative to (a) body weight (median 5650, interquartile range [IQR] 4833-6522 vs median 4454, IQR 4309-4743, respectively), (b) ratio between skull length/width (70 833, IQR 62490-126 209 vs 48 064, IQR 22984-64 279, respectively), and (c) skull length (689.93, IQR 618.55-970.61 vs 460.04, IQR 288.77-561.69, respectively). The proportion of air (oropharyngeal and nasopharyngeal)/soft tissue (tongue and palatal tissue) in brachycephalic dogs was decreased by approximately 60%, and the tongue was approximately 10 times denser in brachycephalic dogs than in mesaticephalic dogs.\u0000\u0000\u0000CONCLUSION\u0000A relative macroglossia was detected in brachycephalic dogs along with reduced air volume in the upper airway. Tongues of brachycephalic dogs were denser than those of mesaticephalic dogs.\u0000\u0000\u0000CLINICAL SIGNIFICANCE\u0000The relative macroglossia in brachycephalic breeds may contribute to upper airway obstruction.","PeriodicalId":123280,"journal":{"name":"Veterinary surgery : VS","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114845476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
