This study reviewed the short-term outcome of transcatheter closure of the defects within the oval fossa using an Amplatzer® Septal Occluder. From January 1997 to December 2000, 210 patients with defects within the oval fossa underwent successful transcatheter closure. We reviewed a total of 190 patients with left-to-right shunts, assessing the patients for possible complications and the presence of residual shunts using transthoracic echocardiogram at 24 h, 1 month, 3 months and one year. Their median age was 10 years, with a range from 2 to 64 years, and their median weight was 23.9 kg, with a range from 8.9 to 79 kg. In 5 patients, a patent arterial duct was closed, and in 2 pulmonary balloon valvoplasty performed, at the same sitting. The median size of the Amplatzer® device used was 20 mm, with a range from 9 to 36 mm. The median times for the procedure and fluoroscopy were 95 min, with a range from 30 to 210 min, and 18.4 min, with a range from 5 to 144 min, respectively. Mean follow-up was 20.8 ± 12.4 months. Complete occlusion was obtained in 168 of 190 (88%) patients at 24 h, 128 of 133 (96.2%) at 3 months, and 103 of 104 (99%) at one year. Complications occurred in 4 (2.1%) patients. In one, the device became detached, in the second the device embolized into the right ventricular outflow tract, the lower end of the device straddled in the third, and the final patient had significant bleeding from the site of venupuncture. There were no major complications noted on follow-up. We conclude that transcatheter closure of defects within the oval fossa using the Amplatzer® Septal Occluder is safe and effective. Long-term follow-up is required, nonetheless, before it is recommended as a standard procedure.

Case series summary Pantarsal arthrodesis (PTA) was performed in seven tarsi of six cats, using orthogonal (dorsal and medial) veterinary cuttable plates (VCPs) without postoperative external coaptation. Short-term outcomes, arthrodesis progression and complications were assessed using a retrospective review of case notes (veterinary examination) and radiographs. Long-term outcomes were assessed via owner questionnaire (Feline Musculoskeletal Pain Index [FMPI]). Mean angle of PTA was 136° (range 116–166°). Intraoperative complications were recorded in two cases, both involving failure of the drill bit during drilling for calcaneotibial screws. Postoperative complications were encountered in a case of bilateral single-session PTA. These included gastrocnemius myotendinopathy on the right, and long-term protrusion of a screw head from the skin on the left. Both complications were resolved surgically, through resection of the implicated gastrocnemius tendon of insertion and removal of the plate, respectively. FMPI assessment was performed for all six cats a mean of 8.8 months (range 6–16 months) following surgery. Mean score for the first part (assessing ability to perform normal activities) was 92.2% (range 80.9–97.1%). Mean score for the second part (owner perception of pain) was 95.8% (range 87.5–100%). Mean overall score (mean score for parts 1 and 2 combined) was 92.3% (range 81.6–97.4%). PTA may be performed in cats using orthogonal VCPs to treat severe tarsal injuries. It may be prudent to avoid single-session bilateral PTA in cats. Relevance and novel information This case series documents a novel technique as an alternative for PTA in cats with talocrural injuries. Long-term outcome and complications presented in this case series are evaluated and discussed.

AbstractHomografts have long been used for right ventricular outflow tract (RVOT) reconstruction. Tissue banks struggle to meet the clinical demand of tissue, with insufficient donor availability and strict recommendations on tissue quality with high proportions of discards. This study analyzes the long-term outcome of patients receiving a homograft with small fenestrations of the cusps or other structural changes, to evaluate if minor impairment of the homograft affects the durability. Homograft characteristics and patient outcome were described. Follow-up was maximum 24 years. Structural changes of the homografts were analyzed in relation to patient outcome, using univariable and multivariable Cox proportional hazard regression. Between 1995 and 2018, 468 patients received 535 homografts in the RVOT in Lund. Median recipient age was 13 years. There were 137 (26.9%) reinterventions. Freedom from reintervention was 75.8% (95% CI 71.3–79.7%) at 10 years and 57.4% (95% CI 50.0–64.0%) at 20 years. Small fenestrations of the cusps, fibrosis of the cusps and minor atheromatosis of the vessel did not show any statistically significant impact on long-term outcome, hazard ratio = 0.46 (95% CI 0.11–1.87, p = 0.276) and hazard ratio = 0.80 (95% CI 0.25–2.56, p = 0.704). Minor structural changes of the homografts seem to be acceptable without affecting the long-term durability.

Abstract OBJECTIVES The right ventricular outflow tract reconstruction is a common necessity in congenital cardiac surgery. As homograft availability is limited, alternatives need to be evaluated. The Labcor® conduit consists of a porcine tricomposite valve assembled inside a bovine pericardium tube. This study presents intermediate-term results for its utilization for right ventricular outflow tract reconstruction. METHODS Labcor conduits were implanted in 53 patients (February 2009–July 2016). We analysed perioperative data, freedom from conduit failure and risk factors for conduit dysfunction. RESULTS The most common diagnosis was Tetralogy of Fallot (n = 20, 37.7%). The median age at surgery was 10.0 [interquartile range (IQR) 4.9–14.3] years. Pulmonary artery plasty (n = 37, 69.8%) and augmentation of the right ventricular outflow tract (n = 16, 30.2%) were often part of the procedure. The median conduit size was 21 (range 11–25) mm. There was no in-hospital death. The median follow-up after surgery was 4.6 (IQR 3.4–5.6) years. Fourteen patients (27.5%) developed conduit failure with stenosis being the main cause. Freedom from conduit failure was 98.0% at 2 and 80.5% at 5 years. The median longevity of the conduit was 7.4 years (95% confidence interval 5.1–9.8 years). Younger age and smaller conduit size were related to conduit failure. CONCLUSIONS Utilization of the Labcor conduit revealed acceptable intermediate-term results. The conduit appeared to be functioning sufficiently well within the first 5 years in the majority of patients. The higher rate of failure concerning smaller conduits might be associated with somatic outgrowth; however, conduit degeneration as common and long-term outcome still needs to be evaluated.

Case Series Study

SummaryA retrospective case series study was done to determine the long-term outcome of operations upon dogs treated for canine hip dysplasia by means of a triple pelvic osteotomy (TPO). Twentyfour dogs with bilateral hip dysplasia, that received a unilateral TPO between January 1988 and June 1995, were re-examined at the Ontario Veterinary College. The assessment included physical, orthopedic and lameness examinations, standard blood work, pelvic radiographs and force plate gait analysis. They were compared to bilaterally dysplastic dogs that had not been treated, and also to normal dogs. Force plate data analysis demonstrated a significant increase in peak vertical force (PVF) and mean vertical force over stance (MVF) in the limb that underwent surgical correction by means of a TPO, when compared to the unoperated hip. It was determined that performing a unilateral TPO on a young dysplastic dog resulted in greater forces and weight bearing being projected through the TPO corrected limb when compared to the unoperated limb.Dogs with bilateral hip dysplasia treated with a unilateral triple pelvic osteotomy (TPO) were assessed by force plate gait analysis, radiographs and orthopedic examination. There was a significant increase in hip Norberg angles over time, although degenerative changes did progress. Limbs that had been operated upon had significantly greater peak and mean ground reaction forces than limbs that had not received an operation.

Abstract Background Calvarial Ewing tumor is a relatively rare differential among bony neoplasms. We present our experience of managing primary calvarial Ewing sarcoma (EWS), highlighting their clinical and radiological findings. Method In a retrospective analysis, we evaluated our 12-year database for pathologically proven EWS. A literature search was conducted for the comparative presentation and update on the management and outcome. Result From January 2008 to December 2020, we managed eight patients (male:female = 5:3; age range 6 months to 19 years, mean 11.5 years) harboring primary calvarial EWS. All cases underwent wide local excision; two patients required intradural tumor resection, while one required rotation flap for scalp reconstruction. Mean hospital stay was 8 days. All patients received adjuvant chemo- and radiotherapy. Three patients remained asymptomatic at 5 years of follow-up, while two patients died. Conclusion Primary calvarial EWS is a rare entity. It usually affects patients in the first two decades of life. These tumors can be purely intracranial, causing raised intracranial pressure symptoms, which may exhibit rapidly enlarging subgaleal tumors with only cosmetic deformities or symptoms of both. Radical excision followed by adjuvant therapy may offer a favorable long-term outcome.
