Stellate Ganglion Block for PTSD: What Veterans Need to Know

By CombatProse | USMC

If you’ve done the therapy — CPT, Prolonged Exposure, EMDR — and your PTSD symptoms still haven’t moved enough, there’s a procedure gaining serious traction at the VA right now: Stellate Ganglion Block (SGB) for PTSD. It’s a nerve block injection that takes about 15 minutes and, in a growing body of research, produces meaningful symptom relief that conventional therapy alone hasn’t delivered. Here’s what SGB is, what the 2026 evidence says, who qualifies, and how to start the conversation with your provider.

What Is Stellate Ganglion Block (SGB)?

SGB has been used in pain management for decades. A trained specialist — typically an anesthesiologist — uses ultrasound or fluoroscopic imaging to guide a needle to the stellate ganglion, a nerve bundle at the base of the neck near the C6 vertebra. A local anesthetic (usually ropivacaine or bupivacaine) is injected around the nerve tissue. The procedure takes 15–30 minutes.

The mechanism: PTSD is driven in part by a dysregulated sympathetic nervous system — the threat-response machinery that won’t power down after combat. The stellate ganglion has direct connections to the amygdala and hypothalamus. Blocking it temporarily disrupts hyperarousal at the neurological level, not just the behavioral one.

What the Research Says in 2026

This is not fringe medicine. A 2026 review in Current Psychiatry Reports — the most comprehensive literature review to date, covering 18 studies published through October 2025 — found that across large cohort studies, 70–81% of patients showed clinically significant PTSD symptom improvement following SGB. One retrospective analysis of 327 patients found 81% improved. A 75-patient study reported 96% of patients showed significant improvement at 1 week, 1 month, 3 months, and 6 months. The VA’s own clinical demonstration project, led by VA Long Beach Healthcare System, administered over 185 SGB treatments with no serious adverse events and 100% patient satisfaction.

Key data points:

Effects typically last 3–6 months and can be repeated with maintained efficacy
Hyperarousal symptoms — scanning, sleep disruption, threat-mode locking — show the most consistent improvement
Severe cases may respond more strongly than mild-moderate cases
90% of non-responders to a right-sided block improve with a subsequent left-sided block

The VA’s Health Systems Research brief notes that RCT evidence remains “insufficient” by strict standards — one RCT was inconclusive. Four large RCTs are actively underway. But the cohort and case series data are consistent and significant, particularly for veterans who’ve failed first-line treatments.

Who Qualifies for SGB at the VA

SGB is not yet a standard VA treatment. Only 11 of 170 VA facilities offer it for PTSD. The federal TREAT PTSD Act (H.R. 1947) would direct the VA and DoD to expand SGB access systemically — it has not yet passed as of June 2026.

Based on VA guidance and active clinical trial criteria, you may be a candidate if you:

Have a formal PTSD diagnosis (DSM-5, CAPS-5 score above 26 for moderate-severe)
Have completed at least one evidence-based treatment — CPT, PE, EMDR, or adequate medication trial — without sufficient or lasting relief
Are currently enrolled in VA care and under a VA mental health provider
Do not have contraindications: active thyroid disease, coagulopathy, prior anterior neck surgery, active infection, severe uncontrolled depression, or current substance dependence (within 6 months)

How to Ask Your VA Provider About SGB

Walk in prepared, not just interested.

Step 1: Document your treatment history. List completed CPT or PE sessions with dates, provider, and PCL-5 scores before and after. If you’ve tried medications, document the drugs, doses, and duration. VA providers need evidence of an adequate evidence-based treatment trial.

Step 2: Request a referral to your VA’s PTSD Clinical Team (PCT). Ask specifically whether your facility or VISN offers SGB, or whether you qualify for travel to a facility that does.

Step 3: Reference the VA’s own SGB patient resource, which states SGB may be considered for veterans with PTSD who have tried evidence-based treatment without significant lasting improvement and are currently under VA mental health care.

Step 4: Ask about active clinical trials. Trial NCT05169190 is specifically recruiting veterans with moderate-severe chronic PTSD who’ve had at least one failed evidence-based treatment. Search ClinicalTrials.gov or ask your VA provider about enrollment through participating VA sites.

Private Options If Your VA Doesn’t Offer It Yet

Private clinics do perform SGB. Cost: typically $1,500–$2,000 per injection. Not covered by most commercial insurance or Medicare/Medicaid (approved for pain management, not PTSD specifically). HSA/FSA payments are often accepted. Only get this done with a board-certified anesthesiologist experienced in ultrasound-guided cervical injections.

The Bottom Line

SGB is not a cure — it’s an intervention that dials down hyperarousal enough to make other work possible. The research shows it’s most effective paired with therapy rather than used alone. If you’ve been through first-line treatments and hyperarousal remains — disrupted sleep, scanning, rage responses — SGB is a legitimate conversation to have with your VA mental health provider. Push for it now rather than waiting for the institution to get there first.
