Manejo de las metástasis vertebrales en la charnela cervico-occipital / Management of vertebral metastases in the cervico-occipital junction

Las metástasis a nivel occipito-cervical corresponden solo al 0,5% de las metástasis del raquis. El manejo de estas lesiones es complejo y conlleva múltiples estudios radiológicos, tales como la radiología simple, la tomografía computarizada (TAC) o la resonancia magnética (RM). Ante la sospecha de afectación vascular también será recomendable la realización de pruebas que valoren la permeabilidad vascular (angio-TC, angio-RM). Este tipo de lesiones, debido a su compleja localización, puede precisar distintos tipos de vías de abordaje; comúnmente será el abordaje posterior, pero en ocasiones se necesitarán abordajes anteriores o anterolaterales asistidos por cirujanos maxilofaciales u otorrinolaringólogos para una correcta exéresis de la tumoración. El dolor con los giros puede orientarnos al diagnóstico en una columna inestable. La RM es la prueba de elección para diagnosticar y estudiar estas lesiones. La presencia de inestabilidad o de clínica neurológica progresiva es indicación de cirugía.(AU)

Occipito-cervical metastases correspond to 0.5% of spinal metastases. The management of these lesions is complex and involves multiple radiological studies, such as simple radiology, computed tomography (CT), magnetic resonance imaging (MRI). Is vascular involvement is suspected, tests to assess vascular permeability are also recommended (angioCT). This type of lesion, due to its complex location, may require different types of approaches, commonly it will be the posterior approach, but sometimes anterior or anterolateral approaches will be needed assisted by maxillofacial surgeons or otorhinolaryngologists for correct excision of the tumor. Pain with head turning can guide us to the diagnosis in an unstable spine. Magnetic resonance is the test of choice to diagnose and study these lesions. The presence of instability or progressive neurological symptoms are an indication for surgery.(AU)

Utility of percutaneous catheters for local anaesthetics infusion for postoperative pain control in lumbar arthrodesis. A prospective cohort study. / Utilidad de los catéteres percutáneos para perfusión continua de anestésico local en el manejo del dolor postoperatorio en pacientes sometidos a artrodesis lumbar instrumentada. Estudio de cohortes prospectivas.

OBJECTIVE: To evaluate whether postoperative continuous wound infiltration of levobupivacaine through two submuscular catheters connected to two elastomeric pumps after lumbar instrumented arthrodesis is more effective than intravenous patient-controlled analgesia. MATERIAL AND METHODS: An observational, prospective cohorts study was carried out. The visual analogue scale, the need for additional rescue analgesia and the onset of adverse effects were recorded. RESULTS: Pain records measured with visual analogue scale scale were significantly lower in the 48hours postoperative record at rest (p=.032). The other records of visual analogue scale showed a clear tendency to lower levels of pain in the group treated with the catheters. No statistically significant differences were found in the rescue analgesia demands of the patients. The adverse effects were lower in the catheter group (6 cases versus 11 cases) but without statistical differences. CONCLUSIONS: A trend to lower pain records was found in the group treated with catheters, although differences were not statistically significant.
