ABSTRACT

Abstract Prone position though is commonly used for better access to surgical site, but may be associated with a variety of complications. Perioperative Visual Disturbances or loss is rare but a devastating complication that is primarily associated with spine surgeries in prone position. In this case we report a 42 year old ASA-II patient who developed anisocoria with left pupillary dilatation following lumbar microdiscectomy in prone position. Following further evaluation of the patient, segmental pupillary palsy of the left pupillary muscles was found to be the possible cause of anisocoria. Anisocoria partially improved but persisted till follow up.


Resumo O posicionamento em decúbito ventral, embora comumente usado para melhorar o acesso ao local cirúrgico, pode estar associado a uma variedade de complicações. Distúrbios ou perda visual no Perioperatório é uma complicação rara, mas devastadora, que está principalmente associada à cirurgia de coluna vertebral em decúbito ventral. Relatamos aqui o caso de um paciente de 42 anos de idade, ASA - II, que desenvolveu anisocoria com dilatação pupilar esquerda após microdiscetomia lombar em decúbito ventral. Após uma avaliação adicional do paciente, observamos que a paralisia segmentar dos músculos pupilares esquerdos seria a possível causa de anisocoria. A anisocoria melhorou parcialmente, mas persistiu até o acompanhamento.

ABSTRACT

Resumen: Introducción: Estudio prospectivo en pacientes afectos de hernia discal lumbar L5 S1 tratados mediante la U-Force interespinosa N6. El espaciador interespinoso denominado "U" está realizado en titanio y es colocado entre las apófisis interespinosas. Material y métodos: 50 pacientes operados de hernia discal lumbar fueron evaluados; 25 pertenecían al grupo U-N6 y 25 sólo fueron tratados con microcirugía. Se les realizó valoración clínica y estudios radiológicos seriados. Todos los individuos tuvieron un seguimiento durante dos años (2013-2014). Resultados: Nuestro estudio revela que el uso del dispositivo fue más efectivo (estadísticamente significativo) para el retraso de la inestabilidad que sólo la técnica quirúrgica (p < 0.01). Permitió su colocación en 90% de los sujetos. Conclusión: El uso de este dispositivo retrasa el colapso vertebral y, por ende, la inestabilidad del segmento operado. Noventa por ciento de los casos del grupo N6 presentan el dispositivo a nivel de L5 S1 versus 60% del grupo histórico con otros dispositivos (2004-2011).


Abstract: Introduction: We conducted a retrospective study in patients with disc herniation and compared the results obtained in individuals treated with the U device N6 with those acquired in patients treated without any device. The U device is a titanium alloy implant that is placed between the spinous processes. Material and methods: In a cohort of 50 patients with degenerative lumbar disc, 25 underwent surgical treatment in which the U device was placed and 25 control individuals were treated with discectomy alone. Patients underwent serial follow-up evaluations, and radiographic assessment was used to determine the outcome. Up to two years of follow-up data were obtained in all patients (2013-2014). Results: Statistically significant improvement was seen in patients treated with the coflex device in the management of lumbar disc degeneration to avoid lumbar instability in the future (p < 0.01). It allowed its placement in 90% of the patients. Conclusions: Our study shows that the coflex device was more effective than the discectomy group in the management of lumbar instability. Ninety percent of the cases of the N6 group present the device at L5 S1 versus 60% of the historical group with other devices (2004-2011).

ABSTRACT

Os autores fazem uma revisão da literatura abordando conhecimentos neuroanatômicos da raiz e do gânglio da raiz dorsal. Descrevem a técnica para os acessos interlaminar e intertransverso com o uso de afastador de Caspar tubular cilíndrico e dreno de Penrose como auxiliares no afastamento da musculatura. Basearam-se em 502 casos operados em 25 anos. O objetivo deste trabalho é descrever uma técnica com incisão pequena na pele, baixa agressividade para as estruturas anatômicas, sem perda funcional da musculatura paravertebral, campo cirúrgico amplo, facilidade de execução com as duas mãos, alta hospitalar precoce em torno de 24 horas e baixo custo.


The authors review the literature addressing neuro-anatomical knowledge of the root and root ganglion dorsal. Describe the technique for the interlaminar and intertransverso access using tubular retractor Caspar cylindrical Penrose drain as an aid in muscular retraction. Based-seem 502 cases operated in 25 years. The objective of this paper is to describe a technique with small skin incision, low aggressiveness anatomical structures without functional loss of paraspinal musculature, broad surgical field, easy work with both hands, high early hospital about 24 hours and low cost.
