Pediatric vertebral artery dissection and ischemic stroke following chiropractic manipulation

Pediatric vertebral artery dissection (VAD) following chiropractic cervical manipulation (CCM) is a rare phenomenon. As chiropractic care of pediatric populations increases internationally, it is imperative to increase awareness of this cause of VAD.

This case-report describes a patient encountered in the Department of Neurological Surgery, Indiana University School of Medicine, USA. He was a 20-month-old male who presented nonspecifically with acute onset of

• lethargy,
• vomiting,
• cyanosis,
• respiratory distress.

Cerebrovascular imaging revealed a luminal irregularity in the V4 segment of the right vertebral artery, consistent with dissection. The patient’s guardian later provided history of taking the child for cervical chiropractic corrections immediately prior to the patient’s presentation to the emergency department.

The patient was managed non-operatively. Intubation was performed due to respiratory distress and managed with fluids, vasopressors, antimicrobials, and high-flow oxygen. The patient was extubated four days after presentation, and pressors were discontinued upon achievement of hemodynamic stability. A few days after extubation, the patient was ambulating and able to interact with objects and caretakers. Aspirin therapy was initiated and continued after discharge. The patient was followed with annual appointments and imaging. At two-year follow-up, CTA demonstrated an asymmetrically small right vertebral artery, accompanied by encephalomalacia of the right posterior occipital lobe. MRA demonstrated diffuse narrowing of the V4 segment of the right vertebral artery, albeit less pronounced than prior MRAs. Aspirin was discontinued by an outside following team due to stability of imaging findings. The parents were advised to avoid contact sports to avoid trauma and recurrent stroke.

The authors found 2 further cases of pediatric VAD in the published literature following CCM. Non-specific presentations were noted in both of them. Appropriate diagnosis of pediatric VAD requires increased surveillance in response to a thorough history and an acknowledgment of the plethora of possible patient presentations and etiologies.

The authors concluded that there is an increasing utilization of chiropractors among the pediatric population. In a pediatric patient with nonspecific symptoms, VAD should be considered as a differential diagnosis when there is a history of CCM.

The authors’ statement that “pediatric vertebral artery dissection (VAD) following chiropractic cervical manipulation (CCM) is a rare phenomenon” should be taken with a pinch of salt. As there is no monitoring, the frequency of adverse effects and complications is essentially unknown. Crucially. the risks of CCM for children is by no means confined to VADs. For a fuller account, I recomment reading my book which has an entire chapter on this very subject.

The key messages about CCM for kids might be summarised in the following simple three facts:

1. CCM has no true benefit for children.
2. Thus the risk/benefit balance fails to be positive.
3. Therefore we should discourage partents from taking their kids to see chiropractors.
