Neuropathy following paracervical block in the obstetric patient.
A distinct clinical syndrome of severe buttock pain radiating down the posterior surface of the ipsilateral leg and subsequent inability to ambulate has recently been recognized. The syndrome may develop in the parturient following a paracervical block. This study analyzes 4 cases from the authors' institution and reviews 2 cases from the literature. Onset of the syndrome ranges from 12 hours to 10 days but progressive improvement and complete recovery are the rule. The cause is believed to be secondary to direct trauma or hematoma formation in the area of the sacral plexus. Pelvic induration or a mass in the sacroiliac area may be noted bur abscess formation is not associated. Prevention is difficult but early recognition will facilitate treatment, which is mostly symptomatic.
