A

Used in intestinal surgery to reduce mucosal eversion.

Suture introduced through from serosa through muscular to and mucosa into lumen (as in simple interrupted); the needle is then reintroduced from lumen through mucosa to muscular before it crosses the incision. After crossing incision, it is introduced in the muscular and continued through mucosa to lumen. Needle then reintroduced through mucosa and musclaris to exit from serial surface and suture tied.

63
Q

Characteristics of Lembert suture pattern

A

vertical mattress pattern in continuous fashion - inverting pattern, does not enter lumen.

64
Q

What are the characteristics of cushing and connell patterns

71
Q

Evaluation of Video‐Assisted Thoracic Surgery for
Treatment of Spontaneous Pneumothorax and
Pulmonary Bullae in Dogs

A

Exploratory thoracoscopy was associated with a high rate (58%) of conversion to median sternotomy because of inability to identify leaking pulmonary lesions in dogs with spontaneous pneumothorax and pulmonary bullae.

Failure to convert to a median sternotomy may be associated with recurrent or persistent pneumothorax (i.e., more dogs recurred who did not receive median sternotomy and only received video-assisted surgery.

81
Q

Evaluation of In Vivo Behavior of Ameroid Ring Constrictors in Dogs with Congenital Extrahepatic Portosystemic Shunts Using Computed Tomography

A

No ameroid constrictor closed completely: shunt occlusion was always dependent on soft tissue within the ameroid ring. Residual flow through the shunt was present in 4 dogs (18%), although this caused persistent elevation of shunt fraction in only 1 dog
The change in ameroid constrictor internal diameter was not significantly correlated with serum protein concentration.

Conclusions: Complete shunt occlusion after AC placement is usually dependent on soft tissue reaction. shunt occlusion.
Ameroid constrictors >/=5 mm diameter may not promote complete shunt occlusion

82
Q

Evaluation of the Effects of Topical Zinc Gluconate in Wound Healing

Groups received 1 of the following randomized treatments: zinc gluconate in carrier solution, carrier solution, saline (0.9% NaCl) solution, chlorhexidine, chlorhexidine + zinc gluconate, corticosteroid, and no treatment

A

No significant differences were noted among the groups except the corticosteroid group, in which delayed healing was noted at 4 and 21 days. Bacterial isolates were similar and no differences in pain scores or weight gain were noted among groups. The wounds treated with corticosteroid at day 4 had decreased inflammatory cells and serocellular crust formation, and minimal neovascularization and granulation tissue formation. At day 21, that group had prolonged neutrophilic inflammatory cells, immature fibrosis, less re‐epithelialization, and more prominent serocellular crust.

83
Q

The Effect of Low-Level Laser Therapy on the Healing of Open Wounds in Dogs

What were findings when compared to control (all male) vs. female historical control?

A

No difference in laser vs. control for all parameters.
Historical female controls (study dogs were all male) had significantly greater contraction and epithelialization compared to laser and control. Laser and control had significantly less inflammation than historical group early in would healing but surpassed by day 21. Fibroblast infiltration and collagen less in study groups than historical female controls.

Conclusion - laster didn’t help healing of acute wounds but gender may influence wound healing.

84
Q

Postoperative Respiratory Function and Survival After Pneumonectomy in Dogs and Cats

A

15 of 16 dogs (94%) and 6/7 cats (86%) survived to hospital discharge. After pneumonectomy, dogs had a significantly higher postoperative PaO2 on 21% oxygen and lower postoperative A-a gradient compared to dogs undergoing single lung lobectomy.

85
Q

Knot Security and Tensile Strength of Suture Materials

A

Braided lactomer (polysorb) had greatest force to breaking, whereas polyglytone (caprosyn) had lowest force to breaking. No difference among forces required to break polypropylene and 2 nylon sutures (ethilon and monosof).

Highest strength- 5 throws, lowest = 2 throws.

There was no significant difference between the simple interrupted knots and the knots at the beginning of a simple continuous pattern; however, both were significantly less likely to fail than the knots tied at the end of a simple continuous pattern.

Surgeon experience had a significant effect on failure mode and tensile failure load.

86
Q

Effect of Vascular Seal Configuration Using the LigaSure on Arterial Challenge Pressure, Time for Seal Creation, and Histologic Features

A

Vessel sealing using a single seal created with a single activation cycle was adequate for sealing canine carotid arteries. Histologic examination did not demonstrate any disadvantages to multiple seals or multiple cycle activations.

87
Q

Effect of One‐Lung Ventilation With or Without Low‐Pressure Carbon Dioxide Insufflation on Cardiorespiratory Variables in Cats Undergoing Thoracoscopy

A

No significant effects on hemodynamic variables or oxygen delivery were observed after right or left‐sided OLV alone. Hemodynamic variables were also well‐preserved after OLV–CDI; however, oxygen delivery was significantly lower after left OLV–CDI compared with right OLV–CDI

Conclusions: OLV can be used in cats for thoracoscopic interventions. Although right OLV–CDI was tolerated better than left OLV–CDI, the technique requires further investigation before it can be recommended for widespread clinical use.

88
Q

Effect of Metoclopramide on the Incidence of Early
Postoperative Aspiration Pneumonia in Dogs with Acquired

90
Q

Imaging and Clinical Outcomes in 20 Dogs Treated with

Thin Film Banding for Extrahepatic Portosystemic Shunts

A

The band resulted in complete closure of the vessel around which it was placed in 13 dogs. In the remaining 7 dogs, the vessel lumen was narrowed but not completely closed.

Conclusion: Thin film banding resulted in complete occlusion of many, but not all vessels around which it was placed. Even in dogs with inappropriate band location or with incomplete closure, clinical improvement can be expected based on our results.

Risk Factors for Dehiscence of Stapled Functional End-to-End Intestinal Anastomoses in Dogs: 53 Cases (2001–2012)

A

IBD, location of anastomosis (colon), and intraoperative hypotension are risk factors for intestinal anastomotic dehiscence after stapled functional end-to-end anastomosis in dogs.

11% dehisced. Mortality 83%

Previously suggested risk factors (low serum albumin concentration, preoperative septic peritonitis, and intestinal foreign body) were not confirmed in this study

Q

Long-Term Outcome and Complications Following Prophylactic Laparoscopic-Assisted Gastropexy in Dogs

A

No dogs had GDV in follow-up.

LAG was an effective procedure for prevention of GDV and was associated with high client satisfaction in this cohort of dogs. A moderate rate of postoperative wound complications occurred that were minor and self-limiting in nature.

Q

Prospective Controlled Study of Gastroesophageal Reflux in

Dogs with Naturally Occurring Laryngeal Paralysis

A

Based on the limited number of dogs studied, it appears that dogs with naturally occurring LP have increased acidic reflux events compared to clinically normal dogs. GER can reach the most proximal part of the esophagus.

Q

Comparison of Outcome After Use of Extra-Luminal Rings
and Intra-Luminal Stents for Treatment of Tracheal Collapse
in Dogs

A

Ninety-two percent of dogs undergoing ELR and 100% of dogs undergoing ILS survived to hospital discharge. ELR dogs were significantly younger (P1⁄4.009) and significantly fewer had main-stem bronchial collapse (P

Q

Prospective Surgical Site Infection Surveillance in Dogs

% of dogs with SSI
What were risk factors?
What was most common bug?

A

3%

Hypotension, class of surgery, and use of implant increased risk of SSI.

74% were staphylococci.

Q

Outcome After Pneumonectomy in 17 Dogs and 10 Cats: A Veterinary Society of Surgical Oncology Case Series

  • complication rate
  • mortality rate
A

The overall incidence of complications for dogs and cats were 76 and 80%, respectively, with major complications in 41 and 50%, respectively. Respiratory complications (persistent pleural effusion, oxygen dependence, persistent increased respiratory rate, or coughing) were the most frequent complications. No animals died or were euthanatized intraoperative or within the first 24 hours postoperative. One dog (6%) and 2 cats (20%) died, or were euthanatized in the first 2 weeks postoperative.

Q

Erythrocyte and Biochemical Abnormalities as Diagnostic
Markers in Dogs With Hemangiosarcoma Related
Hemoabdomen

A

There was no significant difference in erythrocyte morphology in abdominal effusion or peripheral blood between dogs with HSA or non-HSA related hemoabdomen. Platelet concentration and peripheral blood PCV were significantly lower in the HSA group

Q

Diagnostic Accuracy of Ultrasound to Predict the Location

of Solitary Hepatic Masses in Dogs

A

The sensitivity of ultrasound localization was 55% for left and right division masses and 29% for central division masses. Correct localization was 3.2 times more likely when the mass arose from the right or left division compared to the central division

Correct localization was significantly less likely when diffuse or multifocal hepatic disease was present

Ultrasound was specific but not sensitive for localizing hepatic masses, and localization accuracy was influenced by mass location and the presence of concurrent liver pathology.

Q

Preoperative Differential Diagnosis of Canine Adrenal Tumors Using Triple-Phase Helical Computed Tomography

A

Of the 36 dogs with adrenal masses, cortical adenocarcinoma was most commonly diagnosed (16 dogs), followed by pheochromocytoma (13 dogs), and cortical adenoma (7 dogs).

morphological features, CT values, and intratumoral contrast attenuation were different between tumor types so may be helpful when arranging differentials

Q

Correlation Between Liver Volume, Portal Vascular Anatomy, and Hepatic Perfusion in Dogs With Congenital Portosystemic Shunt Before and After Placement of Ameroid Constrictors

A

Dogs with smaller preoperative liver volumes had the largest postoperative increase in liver volume. Hepatic arterial perfusion and portal scintigraphy correlate with liver volume and are indicators of successful shunt attenuation. Dogs without visible vasculature on CT angiography had visible portal vasculature postoperatively
