ABSTRACT

OBJECTIVE: To describe and compare onset and intensity of thoracic duct (TD) coloration after injection of methylene blue into the diaphragmatic crus and mesenteric lymph node. STUDY DESIGN: Experimental study. ANIMALS: Adult dogs (n = 18). METHODS: Methylene blue (≤0.5 mg/kg 1% solution) was injected into the left (n = 9) or right (n = 9) diaphragmatic crus via right 10th intercostal thoracotomy. TD coloration was graded over 10 minutes. A right paracostal laparotomy was then performed in all dogs, and an equal volume of methylene blue injected into a mesenteric lymph node (n = 18). TD color grading was repeated. Statistical analysis was performed on subject weight, volume of contrast agent injected between left and right crus, and number of successful outcomes between diaphragmatic crus injection and mesenteric lymph node injection. RESULTS: TD coloration occurred in 6 dogs with left crus injection and 4 dogs with right crus injection with obvious staining present in 2 and 3 dogs, respectively. Successful outcome was noted in all dogs with mesenteric lymph node injection. The number of successful outcomes was significantly greater after mesenteric lymph node injection compared with diaphragmatic crus injection (P < .001). CONCLUSIONS: Methylene blue injected into the diaphragmatic crura and mesenteric lymph node was successful in coloring the TD; however, mean thoracic duct color grade and number of successful outcomes were significantly higher after mesenteric injection.

ABSTRACT

Two dogs, 4 and 7 years of age, were presented for evaluation and treatment of excessive sneezing. Physical examinations in both cases were within acceptable limits except for the presence of a single mass in the left nasal passage in the first case and left-sided nasal discharge in the second case. Rhinoscopy was used to visualize the nasal masses, and in both cases a single mass was surgically removed. Impression smears and histopathology submitted from each mass revealed lymphoplasmacytic and neutrophilic inflammation with spores typical of Rhinosporidium seeberi. These are the first reported cases of nasal rhinosporidiosis in two dogs native to the Upper Mississippi River Valley area with no travel history outside the region.

ABSTRACT

Stoma site metastasis of gastric adenocarcinoma was documented 37 d after partial gastrectomy with gastrostomy tube placement, and 22 d after tube removal. The tube was placed through grossly normal tissue but histopathologic examination revealed neoplasia at the surgical margins and concurrent lymphatic metastasis. Stoma site metastases may be due to direct tumor seeding or hemolymphatic spread.

ABSTRACT

Fracture stabilization using circular external skeletal fixation was evaluated in 14 dogs with antebrachial fractures and 11 dogs with crural fractures. Most dogs were consistently weight bearing on the stabilized limb by 3 days following surgery. Although all dogs developed minor wire/pin tract inflammation and eight dogs developed major wire/pin tract inflammation, postoperative lameness was not consistently associated with wire/pin tract complications. Fractures in 23 dogs achieved radiographic union (mean +/- standard deviation [SD], 61 +/- 21 days; median, 57 days) without additional surgery; two dogs required restabilization of their fractures with linear fixators. Twenty of the 21 owners that could be contacted felt their dog had no (n=15) or only a mild (n=5) intermittent lameness at the time of final, long-term (mean +/- SD, 37 +/- 17 months; median, 42 months) assessment.

ABSTRACT

OBJECTIVE: To report the surgical management of a traumatic distal antebrachial wound using a medial saphenous fasciocutaneous free tissue flap and a type I external skeletal fixator (ESF). STUDY DESIGN: Case report. ANIMALS: A 7-year-old spayed, female Labrador retriever. RESULT: Wound coverage and pancarpal arthrodesis were accomplished during a single anesthetic episode using a medial saphenous fasciocutaneous free tissue flap and type I ESF. A second surgical procedure was performed to expedite healing of part of the original wound that was initially left to heal by second intention. CONCLUSIONS: Free tissue transfer can be used in combination with an ESF for repair of distal antebrachial wounds, allowing orthopedic repair and soft tissue coverage in a single anesthetic episode. CLINICAL RELEVANCE: Concurrent use of free tissue transfer and carpal arthrodesis with an ESF could be used for repair of complex antebrachial wounds without need for multiple procedures, extended hospitalization, and increased cost.

ABSTRACT

Complex long-bone fractures with short juxta-articular fracture segments can be difficult to manage. Recently, IMEX Veterinary, Inc., began producing titanium hybrid rods that can be secured to ring components of the IMEX circular external skeletal fixation system to create SK-circular hybrids. In this case series, SK-circular hybrids were used to stabilize long-bone fractures (two femoral, one humeral, and three tibial fractures) with short distal bone segments in three dogs and three cats with body weights ranging from 1.9 to 15 kg (mean, 6.7 kg; median, 5.4 kg). Although three cases required surgical revision, animals ambulated well and all fractures obtained union. Time to radiographic union ranged from 62 to 137 days (mean, 90 days; median, 84 days). The functional outcome was considered excellent in all six cases.

ABSTRACT

OBJECTIVE: To compare the accuracy of reduction and biomechanical characteristics of acetabular osteotomies repaired with luted and nonluted reconstruction plates. STUDY DESIGN: In vitro study. ANIMALS: Pelves removed from 12 adult greyhounds. METHODS: Acetabular osteotomies were created and repaired with a 6-hole, 2.7-mm reconstruction plates in 24 cadaver hemipelves. Ten hemipelves each were assigned to group I and group II. An impression cast of each acetabulum in group I was made before luting (preluting cast). Group I plates were then elevated, luted, and replaced. A second cast of each acetabulum in group I was then made (postluting cast). Step, gap, and total areas of articular osteotomy incongruence were determined from the casts. Group I (luted plate repairs) and group II (nonluted plate repairs) hemipelves were loaded ventral-to-dorsal using a materials-testing machine. Stiffness, yield load, and maximal load sustained were determined. RESULTS: Mean gap and total area of articular osteotomy incongruence for group I preluted plate repairs (7.1 mm(2) and 8.6 mm(2), respectively) were significantly greater than for group I postluted plate repairs (4.1 mm(2) and 5.1 mm(2), respectively). Mean stiffness and maximal load for group I (681 N/mm and 2,555 N, respectively) were significantly greater than for group II (360 N/mm and 1,730 N, respectively). Mean step area and mean load at yield values were not significantly different between groups. CONCLUSIONS: Luted plate repairs of osteotomized acetabulae result in improved reduction and are stiffer and stronger than nonluted plate repairs. CLINICAL SIGNIFICANCE: Plate luting may improve the accuracy of reduction of acetabular fractures where anatomic reduction is required. Plate luting may also increase the stiffness and strength of fracture repairs and arthrodeses.
