About this trial

This study is testing a new approach to help people with migraine headaches. Researchers want to find out if using electrical stimulation to affect blood flow in the external carotid artery is safe and practical for helping control headaches.

The goal of the study is to determine whether this approach could improve headache symptoms and overall outcomes for people with migraines.

Trial outcomes

Primary outcomes

1

Safety of Bipolar external carotid artery circulation Stimulation

Safety will be evaluated based on the ability to complete the stimulation procedure without technical failure, serious complications, or procedure-related neurological deficits.

Time frame
Measured Perioperative/Periprocedural and through the immediate post-procedural period (up to 24 hours).
2

Feasibility of Bipolar external carotid artery circulation Stimulation

Feasibility will be demonstrated if stimulation can be successfully initiated and completed using the intended bipolar approach.

Time frame
Measured Perioperative/Periprocedural and through the immediate post-procedural period (up to 24 hours).

Secondary outcomes

1

Headache Severity Measured by the Visual Analog Scale (VAS)

Headache severity will be assessed using the Visual Analog Scale (VAS), a validated 0-10 cm scale in which participants indicate headache intensity by marking a point along a continuous line representing "no pain" to "worst pain."

Time frame
At baseline, Perioperative/Periprocedural, immediately post-procedure, and at following post-op times 2-4 hours, 7 days, 30 days, and 90 days.
2

Physiologic Responses During Stimulation

Physiologic responses, including heart rate, blood pressure, respiratory rate, and oxygen saturation, will be recorded during active stimulation to assess acute physiologic effects.

Time frame
Perioperative/Periprocedural
3

Patient-Reported Qualitative Outcomes

Patient-reported qualitative outcomes includes perceived headache relief, tolerability of the intervention, and the presence of any new or worsening symptoms.

Time frame
At 24 hours, 7 days, 30 days, and 90 days after the procedure.
4

Number of Adverse Events

Adverse events and serious adverse events including seizures, vascular complications, and signs of lidocaine toxicity.

Time frame
Perioperative/Periprocedural, and at follow-up at 7 days, 30 days, and 90 days.
