Article: Surgical construction of a novel simulated carotid siphon in dogs.
[show abstract] [hide abstract]
ABSTRACT: The development and preclinical assessment of new endovascular devices necessitate readily available and reproducible animal models. The purpose of this study was to develop an in vivo carotid siphon model for testing the properties of covered stents specially designed for the intracranial vasculature. Six carotid siphon-shaped devices were created. Six dogs underwent surgery to expose and isolate both common carotid arteries (CCAs). The right CCA origin was ligated and incised distal to the ligation point after temporary constriction of the distal right CCA. The distal left CCA was ligated and incised proximal to the ligation point after the left CCA origin was temporarily clamped. The proximal isolated left CCA was passed through the shaped device and then anastomosed end-to-end to the distal isolated right CCA. Finally, the shaped device was fixed and embedded in the neck. Intraarterial digital subtraction angiography was performed at 7 days, 2 weeks, and 1 month postprocedure. All models underwent endovascular interventional simulation. The carotid siphon models were evaluated. The animals tolerated the surgical procedure well. The mean time for surgical construction of the model was 90 minutes. The morphology and endovascular manipulation of the siphon models were similar to those in humans. Stenosis of anastomotic stoma occurred in 2 models, and mural thrombosis of anastomotic stoma occurred in 1 model; however, all models were patent at postprocedural follow-up angiography. Surgical construction of an in vivo carotid siphon model in dogs with carotid siphon-shaped devices is feasible and potentially useful for testing neurovascular devices.Journal of Neurosurgery 01/2009; 109(6):1173-8. · 2.96 Impact Factor -
Article: Percutaneous vertebroplasty for eosinophilic granuloma of the cervical spine in a child.
[show abstract] [hide abstract]
ABSTRACT: We report a case of eosinophilic granuloma at the fourth cervical vertebra in a 10-year-old girl presenting with a 1-month history of cervical pain and stiffness. This lesion was histologically diagnosed by needle biopsy and then treated by percutaneous vertebroplasty. After the procedure, the cervical pain and stiffness resolved rapidly. The height of the vertebral body remained stable without further collapse over a 6-month follow-up period.Pediatric Radiology 11/2007; 37(10):1053-7. · 1.67 Impact Factor
