Abstract
Over the past 50 years, image-guided procedures have been established for a wide range of applications. The development and clinical translation of new treatment regimens necessitate the availability of suitable animal models. The juvenile Göttingen minipig presents a favourable profile as a model for human infants. However, no information can be found regarding the vascular system of juvenile minipigs in the literature. Such information is imperative for planning the accessibility of target structures by catheterization. We present here a complete mapping of the arterial system of the juvenile minipig based on contrast-enhanced computed tomography. Four female animals weighing 6.13 ± 0.72 kg were used for the analyses. Imaging was performed under anaesthesia, and the measurement of the vascular structures was performed independently by four investigators. Our dataset forms a basis for future interventional studies in juvenile minipigs, and enables planning and refinement of future experiments according to the 3R (replacement, reduction and refinement) principles of animal research.

Image-Guided Thromboembolectomy of Acute Arterial Occlusion in Children. Ann Vasc Surg 2016; 34:270.e1-5. [PMID: 27177711 DOI: 10.1016/j.avsg.2015.12.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2015] [Revised: 11/19/2015] [Accepted: 12/12/2015] [Indexed: 11/21/2022]
Abstract
Acute arterial thromboembolism (ATE) is rare in childhood, but this medical emergency requires immediate treatment. Described herein are separate instances of lower extremity ATE in 2 children, both of whom were successfully managed through image-guided thromboembolectomy (IGT). One patient, a 34-month-old female child with nephrotic syndrome, developed bilateral iliac and popliteal thromboembolic arterial occlusions after high-dose steroid therapy. Another 9-year-old girl suffered an embolism of left popliteal artery due to infectious endocarditis. Both patients underwent IGT using over-the-wire Fogarty catheters. During follow-up, presenting symptoms resolved without significant complications.

Abstract
It has only been in the last several decades that abscesses within deep compartments, particularly within the abdomen and pelvis, have become safely accessible with imaging guidance. Since that time, percutaneous abscess drainage has become the standard of care in children. We review the clinical features, diagnosis, and image-guided management of abdominal and pelvic abscesses in children.

Abstract
OBJECTIVE To describe imaging of typical conditions and diseases in the neonatal genito-urinary (GU) tract. METHOD The use, the applications, and typical findings using standard imaging techniques (e.g., ultrasound, US, voiding cystourethrography, VCUG) are described, with emphasis on technical aspects, indications, and restrictions in neonatal queries. Only basic applications as used in routine clinical work are included, other more sophisticated and advanced imaging techniques such as scintigraphy, MR-urography, genitography or image-guided interventional procedures will only briefly be mentioned. SUMMARY AND CONCLUSION Conventional imaging methods are valuable and - particularly in the neonatal GU tract - sometimes irreplaceable. Skillfully used basic imaging techniques, particularly of US (including modern methods such as Doppler sonography, Harmonic imaging or contrast enhanced US), supplemented by fluoroscopy for VCUG can answer most acutely treatment relevant queries. Rarely early scintigraphic studies, genitography, or MRI may become indicated, usually not for establishing the diagnosis, but to collect additional (functional or anatomical) information necessary for deciding on further treatment, or even image guided interventional procedures may become necessary.
