Neuraxial Anesthesia and Risk of Root Damage: A 3D Ex Vivo Study.
NeuroSci

Cauda equina nerve roots may become damaged during neuraxial anesthesia, and post-puncture headache may appear in the case of cerebrospinal fluid leakage if needle tips are deformed due to bone contact when several attempts are needed. Our aim was to verify the correlation between skin-transverse process distance (st) and skin-dural sac distance (d) for calculation of optimal angles in a free visual guide and as a reference for the maximal depth to be traversed by the needle. Randomly selected ex vivo samples ( = 10) were flexed to reproduce the position of the lumbosacral spine during spinal anesthesia.

Background: Spinal meningiomas (SMs) are common benign tumors that are typically treated with surgical resection. The choice of surgical approach may vary depending on the location of dural attachment of the SM, with a posterior approach being the traditional preference. However, there is limited research available on the impact of dural attachment location on outcomes following posterior approach for SM resection.

Background: Post-laminectomy syndrome (PLS) manifests as recurrent chronic back pain, with or without radiating leg pain, affecting 10-40% of patients following laminectomy. While surgical interventions can alleviate recurrent disc herniation or joint instability, medical management of PLS remains challenging due to unsatisfactory outcomes. Epidural fibrosis is a frequent cause of PLS, leading to nerve root tethering and dural sac compression.

Spine (Phila Pa 1976)
December 2024
Department of Research and Innovation, Møre and Romsdal Hospital Trust, Ålesund, Norway.
Study Design: A secondary analysis of data from the NORDSTEN-spinal stenosis trial (SST).
Objective: The aim of the present study was to investigate whether the dural sac cross-sectional area (DSCA) on magnetic resonance imaging (MRI) of adjacent segments decreases after decompressive surgery due to lumbar spinal stenosis (LSS) up to 2 years postoperatively, and to investigate possible associations with baseline variables, including preoperative patient and radiological characteristics, and surgical method used.
Summary Of Background Data: Decompressive surgery for LSS is currently the most common spinal surgery procedure; however, there is limited knowledge on changes in the DSCA over time adjacent to a decompressed segment.
Antiplatelet therapy is not associated with increased risk of complications after lumbar puncture.
J Neurol

Department of Neurology, Medical University of Vienna, Waehringer Guertel 18-20, 1090, Vienna, Austria.
Background: Lumbar puncture (LP) is a critical diagnostic procedure in the evaluation of neurological diseases. Although considered safe, complications such as post-dural puncture headache (PDPH), back pain, subdural hematoma or venous sinus thrombosis may still occur. Whether the use of antiplatelet therapy (APT) increases the risk of complications after LP, remains unclear.
