Stereotactic extralemniscal myelotomy.
A procedure is reported in which radiofrequency lesions were stereotactically placed in the central cord region at the cervicomedullary junction to interrupt selectively the extralemniscal system. Physiological recognition of the target site was based upon the homuncular organization of the dorsal funiculi, which is analysed. Only subjective (segmentally unrelated) analgesia was achieved, usual...
متن کاملPercutaneous Computed Tomography-Guided Spinal Destructive Procedures for Pain Control
The techniques and results of the main percutaneous procedures performed using image guidance with computerized tomography, including cordotomy, trigeminal tractotomy-nucleotomy, and extralemniscal myelotomy, are presented. The advantages of image guidance for anatomical orientation during the procedures and the newly designed radiofrequency needle-electrode systems are stressed.
متن کاملPercutaneous trigeminal nerve radiofrequency rhizotomy guided by computerized tomography with three-dimensional image reconstruction.
BACKGROUND Percutaneous radiofrequency trigeminal rhizotomy offers high rates of complete pain relief for classic idiopathic trigeminal neuralgia. When performed under fluoroscopy, it may cause anxiety for an inexperienced neurosurgeon owing to lack of familiarity with the regional anatomy, lack of reliable landmarks on fluoroscopy, and perceived risks associated with inadvertent puncture of ne...
متن کاملPercutaneous computed tomography-guided oesophageal needle biopsy.
Sir, Biopsies of suspicious lesions in the oesophagus can be readily performed via a flexible endoscope in most settings. However, structuring lesions may require a rigid endoscope under general anaesthesia or a percutaneous approach to successfully biopsy. The percutaneous approach however, is rarely used with upper gastrointestinal tract lesions. We describe the fine needle aspiration (FNA) o...
متن کاملOptical Coherence Tomography Guided Percutaneous Coronary Intervention.
Optical coherence tomography (OCT) is an increasingly available intracoronary imaging modality that provides high-resolution imaging of coronary arteries. Its fundamental reliance on the emission and reflection of light enables rapid data acquisition without compromise of image resolution. As such, OCT can inform operators planning percutaneous coronary intervention (PCI) by accurately defining...
