Complications following spine fusion for adolescent idiopathic scoliosis can be characterized as either intra-operative or post-operative. The most serious and feared complication is neurologic injury, both in the intra- and post-operative period. Other intra-operative complications include dural tears and ophthalmologic or peripheral nerve deficits, which may be related to positioning. Among the most common post-operative complications are surgical site infection, venous thromboembolism, gastrointestinal complications, and implant-related complications...

The VTE is mainly a disease of the older adult, though its incidence has increased significantly in the pediatric population over the past several years. This trend is likely due to enhanced awareness and recognition of VTE, as well as increased prevalence of thromboembolic associated risk factors, such as increases in the proportion of children with predisposing medical conditions. The evaluation and management of a child with VTE is similar to that of adults, however pediatric patients have their own distinct aspects of care, stemming from particularities of the hemostatic system, age-related risk factors and differences in response to anticoagulant and antithrombotic therapy...

BACKGROUND: Venous thromboembolism (VTE) is extremely rare but under recognized in the pediatric population. Although the literature on the use of ultrasound to detect VTEs in adults is plentiful, little has been documented on its use in the pediatric population. CASE REPORT: We present a case of a healthy 16-year-old female who presented to our emergency department with 3 months of dyspnea on exertion and one episode of near-syncope. Point-of-care cardiac ultrasound identified an inferior vena cava thrombosis...

Thromboembolism is being detected at increasing rates in pediatric tertiary care hospitals. The incidence of pediatric thrombophilia differs across countries, and is unknown in Japan. We sent a survey to 520 pediatric department heads and 629 specialists, requesting details on patients who developed symptomatic thromboembolism between 2006 and 2010. Of 280 eligible cases, congenital thrombophilia and other conditions were reported. Congenital thrombophilia (n = 54, 19.3 %) comprised defects in protein C (27), protein S (9), and antithrombin (7)...

Anticoagulation using intravenous bolus administration of unfractionated heparin (UFH) aims to prevent thromboembolic complications in children undergoing cardiac catheterization (CC). Optimal UFH dosage is needed to reduce bleeding complications. We analyzed the effect of bolus UFH on activated clotting time (ACT) in children undergoing CC focusing on age-dependent, anesthesia-related, or disease-related influencing factors. This retrospective single-center study of 183 pediatric patients receiving UFH during CC analyzed ACT measured at the end of CC...

OBJECTIVE: To evaluate the association between Cushing syndrome and hypercoagulability in children. STUDY DESIGN: A prospective, observational study was performed of 54 patients with Cushing syndrome, 15.1 ± 3.9 years, treated at the National Institutes of Health Clinical Center. Coagulation profiles were taken before and 6-12 months after surgery and compared with18 normocortisolemic children, 13.7 ± 3.6 years. RESULTS: At baseline, patients with Cushing syndrome had greater levels of the procoagulant factor VIII (FVIII) vs controls (145 IU/dL ± 84 vs 99 ± 47, P = ...

Phosphodiesterase 3 inhibitors have been used successfully in pediatric patients with acute or chronic myocardial dysfunction over the last two decades. Their protracted continuous intravenous administration is associated with risk of infectious and thromboembolic complications. Weaning intravenous medication and starting oral angiotensin-converting enzyme (ACE) inhibitors and/or beta-blockers can be challenging. We reviewed retrospectively hospital records of 48 patients receiving oral enoximone treatment in a single tertiary pediatric cardiac center between November 2005 and April 2014...

Platelet-dependent thromboembolism is an underlying mechanism in the pathogenesis of stroke. 5-HT2A receptor gene is expressed in human platelet, coronary artery (blood vessels) and brain. A polymorphism T102C at the 5-HT2A receptor gene was found that may possibly affect the 5-HT2A receptor function. As there is no existing data on T102C variant of 5-HT2A receptor gene in pediatric stroke, we aimed to study in this case-control study whether there is a association between this polymorphism and pediatric stroke...

BACKGROUND: Stroke in association with a patent foramen ovale (PFO) may be due to paradoxical embolization via a right to left intracardiac shunt but the exact contribution of PFO to stroke or stroke recurrence in childhood remains unclear. METHODS: To review the relationship of a PFO with stroke, and evaluate associated co-morbidities. An electronic database literature search of Pubmed, Cochrane and EMBASE was performed from January 2000-December 2014. RESULTS: 149 articles were retrieved, with overlap for diagnosis, management, treatment and outcome...

We report a case of middle cerebral artery stroke with heterozygosity for 2 separate hypercoagulable conditions following repair of an H-type tracheoesophageal fistula (TEF) in an infant. Neonatal stroke is rare, occurring in 1 in 4000 births annually in the United States. Stroke after pediatric surgery occurs in approximately 0.05% of patients. Etiologies of stroke in neonates include cardiac, hematologic, vascular, traumatic, metabolic, pharmacologic, infectious, and hypoxemic insults. Thrombophilia has been described in 42% to 78% of neonates with neonatal stroke...

INTRODUCTION: Venous thrombotic events (VTE) are becoming more and more common in children, particularly in the hospital setting. To date, 1 in 200 children admitted to tertiary pediatric hospitals are now being recognized to develop VTE. Amongst those patients with an identified thrombotic occlusion, pediatric patients diagnosed with renal tumors have long been recognized, but their ideal management in the instances of vascular invasion remains controversial. AIM: We describe the clinical behavior of patients diagnosed with renal tumors and extra renal vascular involvement at The Hospital for Sick Children in Toronto, Canada...

The presence of a pathologic mass in the right ventricle (RV) may lead to hemodynamic consequences and to a life-threatening incident of pulmonary embolism. The diagnosis of an unstable thrombus in the right heart chamber usually necessitates intensive treatment to dissolve or remove the pathology. We present a report of an unusual complication of severe ketoacidosis: thrombus in the right ventricle, removed from the tricuspid valve (TV) apparatus. A four-year-old boy was diagnosed with diabetes mellitus (DM) type I de novo...

Patients with cystic fibrosis (CF) are at increased risk of venous thromboembolism, especially in association with central venous catheter use. Coumarin drugs and low molecular weight heparin are frequently used for anti-coagulant therapy, but are more challenging to administer in CF patients. Dabigatran, an oral thrombin antagonist, is an alternative anti-coagulant medication, but its use in CF has not been reported. We describe our experience in successfully using dabigatran for long-term anti-coagulation therapy in two CF patients...
