Curative treatment is available for patients whose fistulas are localized with myelography. Transvenous endovascular embolization has emerged in recent years as a safe, effective, and durable treatment option for patients with CSFVF. Here, we briefly review the clinical presentation of SIH, present diagnostic algorithm by which CSFVFs are identified, and discuss a stepwise treatment paradigm. We then detail endovascular treatment strategies of CSFVF with particular emphasis on direct versus indirect approaches to the fistula, embolization principles, and techniques to minimize complications. With increasing awareness of SIH and enhanced detection of CSFVF, it is important for endovascular neurosurgeons and neurointerventionalists to be familiar with transvenous CSFVF embolization strategies to meet the needs of this patient population.","PeriodicalId":91465,"journal":{"name":"Contemporary neurosurgery","volume":"13 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135455854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reconstructive surgery using nerve transfer has shown great hope in restoring somatosensory injuries such as iatrogenic cervical nerve root palsy. Nerve transfer is justified by using less important donor nerves to regain major function. Nerve transfers are cost-effective procedures increasingly used to treat central and peripheral nervous system injuries. This article provides a comprehensive reanimation strategy to restore lost functions after iatrogenic cervical nerve root palsy. After reading this article, the trainers should explain the importance of surgical reconstruction after iatrogenic cervical nerve root palsy; they should manage preoperative assessments, address various nerve transfers based on the level of injury and pattern of paralysis, and plan for postoperative rehabilitation strategy.","PeriodicalId":91465,"journal":{"name":"Contemporary neurosurgery","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135567873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peripheral nerve disorders may include injury, entrapment, inflammation, tumor, and pain. Differentiating a peripheral nerve condition from one that originates from the spinal or intracranial level is crucial to guiding proper management. A systematic and targeted approach to each patient is required for diagnosis. A comprehensive work-up includes: 1) detailed patient history; 2) thorough physical examination; 3) review of electrodiagnostic studies; and 4) incorporation of diagnostic imaging and (image-guided) diagnostic nerve blocks. Analogous to the “4 legs of a table,” the more findings in each domain that support the same diagnosis, the more certain the diagnosis and more stable the table (Figure 1). We present this framework as a tool for the localization, diagnosis, and treatment of all peripheral nerve issues.","PeriodicalId":91465,"journal":{"name":"Contemporary neurosurgery","volume":" ","pages":"1 - 7"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46329189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
