Cinti JSAP 2019 - Aberrant right subclavian artery causing megaoesophagus in three cats
How do dogs with ARSA usually present?
What diagnostic modality was used for surgical planning, and what was used intra-op to assist with identification of the RSA?
How was it treated?
What was the outcome?
Usually no clinical findings - causes mild constriction of oesophagus and megaO
CT angiography. Endoscopy
Division and ligation of the ARSA
1/3 cats survived
Rossanese JSAP 2023 - Clinical findings, surgical treatment and long-term outcome of dogs and cats with double aortic arch: four cases (2005–2022)
What were the presenting clinical signs?
How were the cases diagnosed?
How was the dominant aortic arch determined?
What was the surgical approach and what surgery was performed?
What was the outcome?
Poor weight gain, regurg, stunted growth
Oseophagogram and CT angiography
Width and size
Left ICS 4
All animals showed a marked improvement during the postoperative period, and all gained weight gradually. Owners’ perception of the surgical procedure outcome and quality of life was described as excel-lent for all animals
Yaginuma JSAP 2023 - Left ventricular outflow tract obstruction caused by a congenital accessory mitral valve leaflet and treated by open-heart surgery in a young dog
What approach was made to access the MVL?
What surgery was performed?
Left atriotomy with CBP
Excision of the AMVL
Maeda JSAP 2020 - Three Dimensional conformal radiation therapy for canine aortic body tumour: 6 cases (2014-2019)
What types of tumours are aortic body tumours?
How do they behave?
What dog breeds are predisposed?
What was the outcome of the 3D conformal radiation therapy?
Chemodectoma
ABT tends to be slow-growing and locally expansive, but it can also be locally invasive
Brachycephalic
In all 6 cases, aortic body tumours responded to three-dimensional conformal radiation therapy
Acute side effects in 4/6 (grade 1 - mild), long term side effects (grade 1) in 3/6

What was the rate of PDA rupture?
What risk factors were identified for rupture?
Overall mortality rate?
Rate of residual flow?

NONE
0.4%
9% (more likely in dogs with rupture)
Claretti JSAP 2019 - Complications during catheter-mediated patent ductus arteriosus closure and pulmonary valvuloplasty.

What % of surgeries had complications? What major complications were seen?
What was the conversion % to open surgery?
What was the overall mortality rate?
Amplatz Canine Ductal Occluder
12%, Pneumothorax, ventricular fibrillation, infundibulum rupture and hemopericardium, vagal reflex
1%
0.8%
Raleigh VS 2022 - The development of ventricular fibrillation as a complication of pericardiectomy in 16 dogs
What % of dogs developed VF due to electrosurgery?
What % of dogs had cardiac arrhythmias prior to VF development?
What % of dogs with VF died intra-op?
53% (8/15)
43% (7/16)
88% (14/16 died due to VF)

What port locations were utilised?
Surgical complication rate?
What was the MST for non-neoplastic cases?
What was the main reason for death in this population?
What % were identified to have a neoplasm? What was the MST?
Subxiphoid transdisphragmatic approach and as caudal as possible 8-10th right IC space for 2nd port . One lung ventilation not necessary!
0%
365d
Recurrent pleural effusion
4/16 (25%), 76d
Chemlovski VS 2021 - Comparison of diameter and length of subclavian arteries to external jugular veins in variably sized dogs: A cadaveric study
What is the clinical relevance of this?
Why is the left subclavian vessel usually used?
When anastomosing vessels, what surgical procedure needs to be performed to the graft and the recipient to prevent thrombosis and stenosis?
What was the conclusion of this study?
To determine the efficacy of the left external jugular vein graft as a substitute for the left subclavian artery in the modified Blalock-Thomas-Taussig shunt (mBTTS)
It has been found to be the correct diameter
Careful removal of the tunica adventitia
External jugular had a longer length but a similar diameter - could be used as a graft
