Combination tibial plateau leveling osteotomy and transverse corrective osteotomy of the proximal tibia for the treatment of complex tibial deformities in 12 dogs.

Objective: To describe a surgical technique, and outcome, for treatment of proximal tibial deformity (varus, valgus, excessive tibial plateau angle [eTPA], tibial torsion and patellar luxation) by combined tibial plateau leveling osteotomy (TPLO) and transverse corrective osteotomy.

Study Design: Cases series.

Animals: Dogs (n=12; 19 stifle joints).

Bilateral laparoscopic subtotal perinephric pseudocyst resection in a cat.

A 17-year-old castrated male domestic shorthair cat was diagnosed with bilateral perinephric pseudocysts (PNPs). Bilateral subtotal resection of the PNPs was performed via a laparoscopic approach. There was no regrowth or reformation of the PNPs after the procedure and the cat's serum concentration of creatinine remained stable for 6 months after surgery.
