The goal of this review article is to describe and provide examples of epidural and non-epidural flow patterns on both conventional fluoroscopy and CT. Specific non-epidural patterns …

2018年10月4日 · The definitive test is injection of contrast medium, but it can be challenging to distinguish subdural from intrathecal flow patterns if small quantities of contrast medium are …

2021年2月2日 · In a study involving 16,638 patients, intrathecal (subarachnoid) contrast medium spread was the most common reason for aborting interlaminar epidural steroid injections . …

This article summarizes the characteristics that distinguish between ideal epidural flow patterns and nonideal subarachnoid, intradural, and other suboptimal contrast flow patterns. …

Retrograde interlaminar ventral epidural injection (RIVEI) may hypothetically be more effective if the catheter is placed at the ventrocaudal aspect of the exiting nerve. We tested that …

Being able to differentiate epidural from nonepidural contrast flow is vital as is recognizing flow to undesired locations. This article summarizes the characteristics that distinguish between ideal …

Objective: To evaluate the pattern and flow of epidural contrast in fluoroscopically guided lumbar interlaminar steroid injections. Design and methods: A prospective case series of 25 (twenty …

Methods: Patients were assessed for anterior epidural spread of contrast under fluoroscopy in anteroposterior and lateral views. After epidural space confirmation, triamcinolone (80 mg) …

CT fluoroscopy (CTF) allows lumbar epidural injection to be performed rapidly, with very low radiation doses to the operator and patient, while allowing precise needle placement. This …

1999年4月1日 · The use of fluoroscopy and radiologic contrast material provides confirmation of accurate needle placement within the epidural space. We describe our technique and …
