Transjugular intrahepatic portosystemic shunt for the treatment of Budd-Chiari syndrome patients: Results from a single center

Purpose: To evaluate the outcome of transjugular intrahepatic portosystemic shunt (TIPS) in patients with Budd-Chiari syndrome (BCS). Patients and Methods: Fourteen patients (11 female, mean age 45.8 years), with symptomatic BCS refractory to conventional therapy, were treated with TIPS placement in our department within a period of 9 years. Stent grafts were primarily used in 12 patients. Mean follow-up time was 38.1 ± 36.1 months (range 7-114). Model for end-stage liver disease (MELD) score, BCS Rotterdam index, and Child-Pugh score were calculated for all patients. In addition, the recently suggested BCS-TIPS prognostic index score (BSC-TIPS PI) was applied. Results: BCS-TIPS PI score was ≤7 in all patients. Most of our patients (12 of 14) had good or intermediate prognosis according to MELD, Rotterdam and Child-Pugh scores. Technical success was achieved in all 14 patients and was accompanied by complete resolution of the symptoms. In 3 patients, the procedure was complicated by hemoperitoneum, which was successfully treated in two patients with coils or stent-graft placement, whereas 1 patient was managed in the operating room. Thirteen patients are symptom and orthotopic liver transplantation-free. Primary patency was 92.8, 84.7, and 58.7 % at 6, 12, and 24 months, respectively. Secondary patency was 100, 100 and 84.6 % at 6, 12, and 24 months respectively. Conclusion: In symptomatic BCS patients with moderate prognosis according to MELD, Child-Pugh, and BCS Rotterdam scores, as well as BCS-TIPS PI score ≤7, TIPS has high clinical success, low morbidity, and no mortality, and it offers durable mid-term resolution of the symptoms and OLT-free survival. © 2013 Springer Science+Business Media and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE)

Advanced magnetic resonance imaging (MRI) techniques of the spine and spinal cord in children and adults

Abstract In this article, we illustrate the main advanced magnetic resonance imaging (MRI) techniques used for imaging of the spine and spinal cord in children and adults. This work focuses on daily clinical practice and aims to address the most common questions and needs of radiologists. We will also provide tips to solve common problems with which we were confronted. The main clinical indications for each MR technique, possible pitfalls and the challenges faced in spine imaging because of anatomical and physical constraints will be discussed. The major advanced MRI techniques dealt with in this article are CSF, (cerebrosopinal fluid) flow, diffusion, diffusion tensor imaging (DTI), MRA, dynamic contrast-enhanced T1-weighted perfusion, MR angiography, susceptibility-weighted imaging (SWI), functional imaging (fMRI) and spectroscopy. Teaching Points • DWI is essential to diagnose cord ischaemia in the acute stage. • MRA is useful to guide surgical planning or endovascular embolisation of AVMs. • Three Tesla is superior to 1.5 T for spine MR angiography and spectroscopy. • Advanced sequences should only be used together with conventional morphological sequences

Review of the principal extra spinal pathologies causing sciatica and new MRI approaches

In this paper we illustrate the principal extraspinal pathologies causing sciatica and new approaches for the study of structures such as the lumbosacral plexus (LSP). Visualisation of the LSP in its entirety is difficult with conventional two-dimensional MRI sequences owing to its oblique orientation. In our institution, we have found that the utilisation of three-dimensional short tau inversion-recovery sampling perfection with application-optimised contrasts using different flip angle evolutions sequence is helpful, allowing multiplanar and maximum intensity projection reconstructions in the coronal oblique plane and curvilinear reformats through the plexus. Diffusion tensor imaging enables the observation of microstructural changes and can be useful in surgical planning. The normal anatomy of the LSP, its different extraspinal pathologies and differential diagnoses are thoroughly presented

Normal Values of Magnetic Relaxation Parameters of Spine Components with the Synthetic MRI Sequence

SyMRI is a technique developed to perform quantitative MR imaging. Our aim was to analyze its potential use for measuring relaxation times of normal components of the spine and to compare them with values found in the literature using relaxometry and other techniques

The corpus callosum: white matter or terra incognita

The corpus callosum is the largest white matter structure in the brain, consisting of 200–250 million contralateral axonal projections and the major commissural pathway connecting the hemispheres of the human brain. The pathology of the corpus callosum includes a wide variety of entities that arise from different causes such as congenital, inflammatory, tumoural, degenerative, infectious, metabolic, traumatic, vascular and toxic agents. The corpus callosum, or a specific part of it, can be affected selectively. Numerous pathologies of the corpus callosum are encountered during CT and MRI. The aim of this study is to facilitate a better understanding and thus treatment of the pathological entities of the corpus callosum by categorising them according to their causes and their manifestations in MR and CT imaging. Familiarity with its anatomy and pathology is important to the radiologist in order to recognise its disease at an early stage and help the clinician establish the optimal therapeutic approach
