Object: Previous reports of redundant nerve roots (RNRs) of the cauda equina have been limited to evaluations based on myelography. Neither the imaging nor the clinical features of RNRs in relation to magnetic resonance (MR) imaging have been elaborated. The MR imaging characteristics of RNRs were evaluated using the Japanese Orthopaedic Association score before and after the surgery.
Methods: There were 44 patients with L4-5 spondylolisthesis in which a complete blockage was demonstrated on myelography. All patients underwent posterior L4-5 interbody fusion. Based the myelographic and MR imaging findings, the patients were stratified into the following three groups: RNRs recognized on both myelographic and MR imaging (Group A); RNRs recognized on myelography but not very evident on MR imaging (Group B); and RNRs not recognized on either myelographic or MR imaging (Group C). Among these three groups, pre- and postoperative clinical symptoms were compared.
Results: There were 16 patients in Group A, 14 in Group B, and 14 in Group C. In terms of preoperative clinical symptoms, there was a significant difference between Groups A and C in the incidence of leg pain and tingling sensation. Significant differences were also noted between Groups A and C and between Groups B and C in ambulatory ability. Evaluation of postoperative clinical symptoms showed a significant difference between Groups A and C in ambulatory ability.
Conclusions: Patients with MR imaging evidence of RNRs presented with more severe clinical symptoms. It is believed that the RNR features derived from MR images represent important findings.

Background: Neuromuscular disorders (NMDs) constitute a heterogeneous group of disorders that affect motor neurons, neuromuscular junctions, and muscle fibers, resulting in symptoms such as muscle weakness, fatigue, and reduced mobility. These conditions significantly affect patients' quality of life and impose a substantial burden on caregivers. Spinal muscular atrophy (SMA) is a relatively common NMD in children that presents in various types with varying degrees of severity.

Background: Due to the heterogeneity of literature findings, stent type selection for the endovascular treatment of complex aorto-iliac occlusive disease remains challenging. The BELSTREAM study, a physician-initiated, prospective, multicenter, single-arm study, aims to report the safety and efficacy of the balloon expandable LifeStream Peripheral Stent Graft System (BD, Tempe, Arizona, USA) for the treatment of complex TASC C and D aorto-iliac artery lesions.
Methods: Seventy patients and 133 lesions were included at six Belgian institutions.

Optimizing the longevity of vascular access in hemodialysis patients remains a critical aspect of patient care, given the significant role of arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs) in enabling effective dialysis. Vascular access complications, such as stenosis, thrombosis, and cannulation-related damage, continue to challenge both the functionality and the sustainability of these access points. Recent advancements underscore the importance of a robust follow-up strategy, integrating clinical evaluations with diagnostic tools like color Doppler ultrasound (CDU) and emerging interventional approaches such as drug-coated balloon (DCB) angioplasty.

Objectives: Complex regional pain syndrome remains a challenging condition characterized by severe, persistent pain and a variety of inflammatory and trophic symptoms. This study aimed to analyze the current literature to evaluate hyperbaric oxygen therapy (HBOT)'s efficacy in treating complex regional pain syndrome (CRPS), focusing on both sympathetically-maintained pain (SMP) and sympathetically-independent pain (SIP) subtypes.
Methods: A comprehensive literature search was conducted in PubMed Clinical Queries using the MeSH term "Complex Regional Pain Syndromes" OR the keyword "CRPS" AND "Hyperbaric Oxygen Therapy" OR the keyword "HBOT".
Headache in infections.

Purpose Of Review: This review explores the phenomenology, pathogenesis, and nosology of headaches associated with infections, an often-overlooked yet clinically significant symptom. With the increasing recognition of secondary headaches in infections, understanding their clinical patterns, mechanisms, and classifications is crucial for accurate diagnosis and management.
Recent Findings: Headaches in infections are ubiquitous but vary in presentation, severity, and underlying mechanisms depending on the causative pathogen.
