Single Stage Combined Approach Sagittal En-Block Spondylectomy for L3 Vertebral Chondrosarcoma: A Technical Note.
Primary malignant tumors of the spine are rare and most commonly occur in lumbar and thoracic vertebrae. We report a rare case of retroperitoneal chondrosarcoma of L3 that was managed with sagittal en bloc spondylectomy following chemoradiation. ⋯ Sagittal en bloc spondylectomy is a preferred surgical approach for eccentrically placed spinal tumors that offers better oncological and functional outcomes.

Surgery is the mainstay of stroke prevention in patients with symptomatic moyamoya disease (MMD). We present the results of a single-center retrospective study of indirect revascularization surgery for adult MMD, emphasizing angiographic outcomes, including dilation of the superficial temporal artery and formation of new collaterals. ⋯ A significant increase in STA diameter on follow-up angiography after encephaloduroarteriosynangiosis was found; however, this was not directly associated with STA collateral development. Rates of postoperative transient ischemic attacks were low, and no patients had a new ischemic or hemorrhagic stroke at last follow-up. The presence of transdural collaterals and the absence of hyperlipidemia were associated with STA collateral development on follow-up angiography, but the causality of this finding is unclear.

Acute kidney injury (AKI) is a complication often observed in critically ill patients, indicating a worsening prognosis. However, factors predicting AKI in subarachnoid hemorrhage (SAH) patients are unclear. This study aims to elucidate the predictors of AKI occurrence. ⋯ AKI occurred in 16.3% of the patients with SAH. Patients who developed AKI had significantly higher uric acid levels. SAH with high uric acid levels warrants attention for AKI.

We aimed to explore the prognostic significance of preoperative magnetic resonance imaging (MRI) variables and novel inflammatory indicators in predicting neurological recovery post-cervical traumatic spinal cord injury (TSCI) in the study. ⋯ Intramedullary hemorrhage and IMLL and NLR are predictors of AIS grade conversion after cervical TSCI. Therefore, we suggest the combination of MRI variables and NLR for the prognostic prediction of AIS grade conversion in patients with cervical TSCI.

To investigate factors influencing the long-term prognosis of patients with sacral Tarlov syndrome after nerve root cuff reconstruction. ⋯ Patients with sacral Tarlov cysts undergoing nerve root cuff reconstruction, particularly those with longer preoperative disease duration and dysuria, are at increased risk of poor long-term prognosis.
