ABSTRACT

PURPOSE:

To investigate the efficacy and the feasibility of application of percutaneous lysis of epidural adhesions in failed back surgery syndrome (FBSS) using a stiff type guide wire and 4F vascular catheter.

METHODS:

Ninety two patients with FBSS were randomly divided into two groups, the control group (treated by injection dexamethasone only) and percutaneous lysis of epidural adhesions group. Visual analog scale scores (VAS) and therapeutic evaluation were observed in the preoperative, seven days postoperative, one month and six months postoperative.

RESULTS:

VAS scores for pain were significantly reduced in both groups at seven days. The VAS scores were in controlled group at one month, six months was significantly higher than that in epidural lysis group. However, there was no statistical difference in VAS scores of one month and six months when respectively compared to that of before operation in controlled group. Patients on epidural lysis reported clinical effectiveness rate was 50%. Patients on control was 5.26%, there was a statistical difference between two groups.

CONCLUSION:

Percutaneous lysis of epidural adhesions by using a stiff type guide wire and 4F vascular catheter is an effective method in the treatment of FBSS and it has a value in clinical application.
RESUMO

OBJETIVO:

Investigar a eficácia e a exequibilidade da aplicação da lise percutânea de aderências epidurais na síndrome pós-laminectomia usando um fio-guia tipo Stiff e um cateter vascular 4F.

MÉTODOS:

Noventa e dois pacientes com síndrome pós-laminectomia foram randomizados em dois grupos grupo controle (tratado somente com injeção de dexametazona) e grupo lise percutânea de aderências epidurais. Escores de escala visual analógica (VAS) e avaliação terapêutica foram observadas no pré-operatório, no sétimo dia de pós-operatório, um mês e seis meses de pós-operatório.

RESULTADOS:

Escores VAS para dor foram significantemente reduzidos em ambos os grupos aos sete dias. Os escores VAS foram mais altos no grupo controle comparado ao da lise epidural nos tempos de um mês e seis meses. Entretanto, não há diferença estatística nos escores VAS de um mês e seis meses quando comparados, respectivamente, àqueles de antes da operação do grupo controle. Pacientes com a lise epidural relataram taxa de eficiência de 50%. Nos pacientes do grupo controle foi 5,26%, havendo diferença estatística entre os dois grupos.

CONCLUSÃO:

A lise percutânea de aderências epidemias usando um fio-guia tipo Stiff e um cateter vascular 4F mostrou-se um método efetivo no tratamento de FBSS e tem valor na aplicação clínica.
