Minimal invasive management of early revision after minimal invasive posterior lumbar fusion.

Background: Minimally invasive spine (MIS) fusion is an increasingly common procedure, with advantages over open approach in the form of minimal dissection and superior early clinical outcome. The frequency of complications is known, but the most appropriate surgical revision for this technique remains unclear.

Hypothesis: The main hypothesis was that early revision surgery, for acute complications after MIS, was possible through mini-invasive approach.

T2 Mapping of the Sacroiliac Joints With 3-T MRI: A Preliminary Study.

Objective: The objective of this study was to assess the feasibility of T2 relaxation time measurements of the sacroiliac joints.

Subjects And Methods: The sacroiliac joints of 40 patients were imaged by 3-T MRI using an oblique axial multislice multiecho spin-echo T2-weighted sequence. Manual plotting and automatic subdivision of ROIs allowed us to obtain T2 values for up to 48 different areas per patient (posterior and anterior parts, sacral, intermediate, and iliac parts).

3D rotational angiography in the endovascular treatment of visceral aneurysms: preliminary experience in a single centre.

Objectives: Endovascular embolization is a valid option for the management of visceral artery aneurysms. Imaging is crucial for providing anatomical assessments, but preoperative non-invasive investigations may not be exhaustive. The aim of this work is to present preliminary experience with the use of three-dimensional rotational angiography (3DRA) in this particular theatre.
