Comparative Evaluation of Postoperative Epidural Hematoma after Lumbar Microendoscopic Laminotomy: The Utility of Ultrasonography versus Magnetic Resonance Imaging.

ABSTRACT:

Introduction

Postoperative spinal epidural hematoma (PSEH) is a severe complication of spinal surgery that necessitates accurate and timely diagnosis. This study aimed to assess the accuracy of ultrasonography as an alternative diagnostic tool for PSEH after microendoscopic laminotomy (MEL) for lumbar spinal stenosis, comparing it with magnetic resonance imaging (MRI).

Methods

A total of 65 patients who underwent MEL were evaluated using both ultrasound- and MRI-based classifications for PSEH. Intra- and interrater reliabilities were analyzed. Furthermore, ethical standards were strictly followed, with spine surgeons certified by the Japanese Orthopaedic Association performing evaluations.

Results

Among the 65 patients, 91 vertebral segments were assessed. The intra-
