Delayed Abdominal Pseudohernia in a Young Patient After an LLIF Procedure: Case Report.
To describe a rare complication of the extreme lateral interbody fusion technique. ⋯ Abdominal pseudohernia is a rare complication of LLIF procedures. The interest of the present case is 3-fold: 1) it is the first delayed case of abdominal pseudohernia after an LLIF procedure; 2) it is the first case described in a young patient in whom risk factors have been identified and discussed; and 3) it is the first case that did not resolve spontaneously and required surgical repair. This exceptional complication must be borne in the mind of the spine surgeon when using the LLIF technique, and special precautions, such as laxatives or respiratory physiotherapy, apart from meticulous atraumatic dissection and closure of the abdominal wall and specific intraoperative monitoring, should be taken in high-risk patients to prevent it.

Although paraclinoid aneurysms are now frequently referred for endovascular treatment, the durability of obliteration is still to be determined. Therefore, direct surgery for paraclinoid aneurysms still remains indispensable. The present study aimed to evaluate the risk factors for the visual impairments in patients with unruptured intradural paraclinoid aneurysms. ⋯ The present study showed that carotid cave location and plug-in method during dural closures were related to postoperative continued visual impairments. Neurosurgeons should carefully consider the surgical indication for unruptured carotid cave aneurysms and avoid plug-in methods.

The modified Rankin Scale (mRS) was developed to monitor functional recovery after stroke, but nowadays it is a treatment outcome measure in elective neurosurgery. Our objective was to study how mRS changes associate with short-term postoperative outcome. ⋯ The mRS changes after elective cranial neurosurgery are inconsistent. The mRS seems to represent functional changes, which do not necessarily associate with detected in-hospital complications.

3T MRI follow-up of large or giant vertebrobasilar dissecting aneurysms which were totally embolized on angiography.
To evaluate the outcomes of large or giant vertebrobasilar dissecting aneurysms (VBDAs) after endovascular total embolization by follow-up 3T magnetic resonance imaging (MRI). ⋯ The efficacy of conventional endovascular treatment (e.g., internal trapping with coils, stent-assisted coiling, and stent placement without coils) for large or giant VBDAs is uncertain. Follow-up angiography alone does not adequately predict the outcome. High-resolution MRI is a worthwhile adjunct to follow these lesions.

Devices enabling long-term intracranial pressure monitoring have been demanded for some time. The first solutions using telemetry were proposed in 1967. Since then, many other wireless systems have followed but some technical restrictions have led to unacceptable measurement uncertainties. In 2009, a completely revised telemetric pressure device called Neurovent P-tel was introduced to the market. This report reviews technical aspects, handling, possibilities of data analysis, and the efficiency of the probe in clinical routine. ⋯ The presented telemetric measurement system is a valuable and effective diagnostic tool in selected cases.
