BLOQUEO TRANSFORAMINAL CERVICAL: RESULTADOS Y COMPLICACIONES

ABSTRACT

Objectives:

To investigate the effect and complications after transforaminal injection for cervicobrachialgia caused by cervical disc herniation.

Methods:

We retrospectively reviewed all patients undergoing fluoroscopy-guided transforaminal injection for radiculopathy caused by cervical disc herniation. During the last seven years, 57 patients (39 female, 18 male, mean age 45.6 years) experiencing cervical radiculopathy underwent cervical foraminal block guided by fluoroscopy by postero-lateral approach. The position of the needle was verified after injection of a small amount of contrast. A glucocorticosteroid was injected after 0.5 ml of 2% lidocaine.

Results:

The local with the highest prevalence of procedures was C6 root (31 procedures); 14 patients underwent C7 block, 7 had C5 block, and 5 in C4. Eight patients (14%) had complications (3 syncopes, 3 transient hoarseness, one patient had worsening of symptoms and one patient had soft tissue hematoma). In total, 42.1% were asymptomatic after the procedure and therefore did not require surgery after the procedure. Other 57.9% had transient improvement, became asymptomatic for at least 2 months but required surgery due to the recurrence of symptoms.

Conclusion:

Cervical foraminal block for cervical disc herniation is a safe way to avoid surgery. Some patients still need surgery after the procedure, but the temporary improvement in symptoms gives the patient some relief while awaiting surgery.
