We present a case series of symptomatic post-operative spinal subdural extra-arachnoid collections that displace the cauda equina roots anteriorly. This is described as the "rising root sign".
Peripheral venous cannulation is one of the most commonly performed medical procedures in hospital medicine. The dorsal metacarpal veins are typically used for cannulation as they are easily accessible. We present the first case of an iatrogenic intratendinous ganglion cyst of the extensor digitorum tendon of the middle finger following intravenous cannulation.
Background: The literature on total en bloc spondylectomy (TES) of bone tumors of the lumbar spine is sparse and heterogeneous. Therefore, the aim was to systematically pool the data from the published studies to quantitatively summarize the morbidity and mortality and to identify factors associated with favorable outcomes and complications.Method: A systematic literature search for studies with individual patient-level data was conducted using specific medical subject heading(MeSH) terms. The outcome measures assessed included complications, tumor recurrence, survival, and function. Individual patient data were pooled from all the studies and quantitatively analyzed to assess the association of different factors with outcomes and complications.Results: Twelve studies were included in this review with a total of 145 TES cases. Of all patients, 50% had at least 1 reported complication post surgery and this was associated with advancing age (OR 1.04, P < 0.001), metastatic disease (OR 5.61, P < 0.001), and adjuvant chemo and/or radiotherapy (OR 20.3, P = 0.001). Intralesional excision (OR 5.2, P = 0.01) and primary malignant tumors (OR 3.3, P = 0.02) were associated with a high recurrence rate. However, the surgical approach was not associated with differences in survival (P = 0.874) or recurrence (P = 0.525) rates. L5 tumor resection was associated with excessive bleeding. Postoperatively, there was an overall improvement in the Frankel grades in most patients.Conclusion: TES is associated with high rates of complications especially in association with primary malignant and metastatic diseases. However, the number of publications on this topic remain scarce and heterogeneous. Hence, there is a need for standardization in the reporting of the outcomes and complications to help with decision-making and consenting for this procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
