Ultrasound-guided atlanto-occipital puncture for myelography in the horse.

Abstract: Complications of cervical myelography arising from the puncture of the subarachnoid space to collect the cerebrospinal fluid and to inject the contrast medium have been described in humans and animals. In this study, 2 ultrasound-guided procedures were developed for puncture of the atlanto-occipital subarachnoid space, collection of cerebrospinal fluid, and injection of contrast medium. Myelography was performed on 6 ataxic horses using these procedures. The first attempt to puncture the subarachnoid space was successful in 5 horses and in one horse, a second attempt was necessary. Collection of cerebrospinal fluid and injection of contrast medium were achieved without difficulty. Ultrasound-guided myelography allowed reduction of potential complications associated with blind percutaneous puncture of the subarachnoid space. Methods described in this study should be tried-at least initially in an experimental setting--to collect cerebrospinal fluid from the atlanto-occipital site in standing horses where it may represent an alternative method when lumbosacral cerebrospinal fluid collection has been unsuccessful or contaminated with blood.

This research explores two new ultrasound-guided procedures to safely puncture the atlanto-occipital subarachnoid space in horses for myelography, decreasing the risk of complications commonly associated with the conventional method.

Background and Objective

  • The study focused on complications occurring from the conventional method of cervical myelography. This is a diagnostic procedure where the subarachnoid space in the spine is punctured to collect cerebrospinal fluid and to inject contrast medium for imaging. Such complications have been reported in both human and veterinary medicine. The aim of this study was to reduce complications by developing and testing two new ultrasound-guided procedures specifically for horses.

Methods

  • The researchers created two ways to puncture the atlanto-occipital subarachnoid space (a space near the top of the spinal cord) in horses using ultrasound guidance. These procedures were used for the collection of cerebrospinal fluid and injection of contrast medium.
  • These procedures were then tested on six horses suffering from ataxia (lack of voluntary coordination of muscle movements).

Results

  • In five out of the six horses, the subarachnoid space was successfully punctured on the first attempt. For the sixth horse, two attempts were necessary.
  • Both the collection of cerebrospinal fluid and the injection of contrast medium were completed without complications.
  • Using ultrasound guidance reduced the potential complications associated with blind percutaneous puncture (puncture without visual aid) of the subarachnoid space, which is the traditional method.

Conclusion and Recommendations

  • Given these results, the researchers recommend using these ultrasound-guided methods for myelography in horses, particularly in experimental settings.
  • The ultrasound-guided method could be a viable alternative when conventional methods — specifically, those involving lumbosacral cerebrospinal fluid collection — have either failed or resulted in contamination with blood.
