The Long-term Effect of Flow Diversion on Large and Giant Aneurysms: An MRI-DSA-Clinical Correlation Study.
The long-term effect of flow diversion (FD) on aneurysms has not been well studied. ⋯ Most aneurysms treated with Pipeline decreased in size, correlating with clinical improvement. Some aneurysms remained unchanged on MRI until a later time point despite early DSA occlusion. It may be reasonable to eliminate early postprocedural imaging and start follow-up only as late as 1 year after FD treatment in clinically stable, asymptomatic patients.

With vertebral compression fractures (VCF), height loss has been associated with kyphotic deformity and intractable pain, 2 indications for potential surgical intervention. Consequently, assessment of factors associated with continual height loss can provide insights regarding management. Computed tomography (CT) Hounsfield units (HU), a measure of radiodensity, have been implicated for the assessment of bone quality. No studies have assessed the relationship between CT HU and traumatic VCF. Consequently, the objective of this study was to evaluate this relationship. ⋯ Age, BMI, and CT HU values are independent predictors of worsening VCF. These factors can help determine appropriate clinical follow-up and need for surgical intervention.

Comparative Study
Biomechanical Study of Three Atlantoaxial Proactive Vertebral Artery Injury Prevention Fixation Combinations.
To evaluate the biomechanical stability of 3 atlantoaxial proactive vertebral artery injury prevention fixation combinations. ⋯ The combination of C1LH and C2ILS supplemented with contralateral TAS or C1LH and TAS or C1LH and C2ILS was superior to bilateral TAS fixation with regard to biomechanics and vertebral artery safety.

The study aimed to investigate optimal surgical timing, methods, and clinical efficacy of bifrontal decompression craniotomy (BDC) on traumatic bifrontal contusions (TBC). ⋯ TBC progressed gradually and deteriorated rapidly; this should be strictly and dynamically observed, and patients should be operated on in a timely manner. Changing the operation-timing score is the gold standard for surgery. Amended BDC can significantly improve the prognosis of patients.

This study assessed whether predominant back pain (pBP) represents a negative outcome predictor in patients undergoing microscopic spine surgery without fusion for a lumbar disc herniation (LDH) or spinal stenosis (LSS). ⋯ The present data suggest that patients with pBP have comparable functional and health-related quality of life outcomes after surgery for LDH or LSS with those of patients with pLP.
