[Discoscanner: indications, technique, tips and tricks, interpretation]. / Discoscanner: indications, technique, trucs et astuces, interprétation.

Discography test associated with the scanner (discoscanner) is an exam that has been a renewed interest in recent few years. Thanks to the emergence of new interventions such as disc prosthesis, the procedures require confirmation of the disc level to deal with and the origin of discogenic symptoms. The aim of this paper is to describe the techniques, challenges and tips as well as the interpretation of functional and morphological examination.

[Posterior percutaneous arthrodesis under CT guidance after surgical anterior arthrodesis: a new technique]. / Arthrodèse percutanée postérieure sous guidage scanner en complément de l'arthrodèse antérieure chirurgicale: une nouvelle technique.

Transfacet screws may be useful for stabilizing segments reconstructed with bone graft or cages, the role of supplementary posterior fixation, particularly minimally invasive techniques such as transfacetar percutaneous screws is relevant. To benefit from a mechanical fixation after anterior arthrodesis without the inconveniences of the open classical posterior surgical intervention, we have developed a new procedure performed under local anesthesia and CT guidance and based on the intra-articular application of screws. This study was designed to demonstrate the feasibility of using a CT-scan to perform posterior arthrodesis of the spine under local anesthesia.

[Splenic artery aneurysm: diagnosis and endovascular therapy]. / Anévrisme de l'artère splénique: diagnostic et thérapeutique endovasculaire.

Splenic artery aneurysms are now diagnosed more frequently thanks to the increase and improvement in different imaging techniques. In case of rupture they are potentially life threatening and thus in certain cases may require appropriate preventive treatment. This treatment should be offered to patients with suspected pseudoaneurysms, with an aneurysm larger than 20mm in diameter, or which is progressing. The development of interventional endovascular radiology has provided new therapeutic options for the management of aneurysms, by excluding the sac from the arterial circulation with coil embolisation or with a covered stent. The success rate of these treatments is between 75 and 100% with significantly less morbidity and mortality than with surgical techniques.
