What is a Stellate Ganglion Block?

A Stellate Ganglion Block (SGB) is a minimally invasive pain management procedure used to diagnose and treat various chronic pain conditions affecting the head, neck, upper limbs, and sympathetic nervous system.

The stellate ganglion is a collection of sympathetic nerves located in the lower part of the neck. These nerves influence blood flow, pain signals, sweating, and other autonomic functions of the face, neck, and upper limbs.

During a Stellate Ganglion Block in Kolkata, a local anaesthetic is injected around the stellate ganglion to temporarily block abnormal sympathetic nerve activity and reduce pain.

At Samobathi Pain Clinic, we perform both Ultrasound-Guided Stellate Ganglion Block and Fluoroscopy-Guided Stellate Ganglion Block, depending on the patient's condition and clinical requirements.

Conditions Treated with Stellate Ganglion Block

A Stellate Ganglion Block may be recommended for:

Complex Regional Pain Syndrome (CRPS)

One of the most common indications for Stellate Ganglion Block is CRPS affecting the upper limb. The procedure can help reduce pain, swelling, stiffness, and improve hand function.

Post-Traumatic Hand Pain

Persistent pain following fractures, crush injuries, burns, or road traffic accidents may respond well to sympathetic blockade.

Peripheral Vascular Disease

Patients suffering from reduced blood circulation in the upper limb may experience symptomatic improvement after Stellate Ganglion Block.

Raynaud's Phenomenon

This condition causes episodes of reduced blood flow to the fingers and may benefit from sympathetic nerve blockade.

Post-Herpetic Neuralgia

Persistent nerve pain following shingles involving the face, neck, or upper limb can sometimes be managed with Stellate Ganglion Block.

Phantom Limb Pain

Some patients with upper limb amputation experience significant pain relief following sympathetic blockade.

Refractory Angina and Vascular Pain

Selected patients with vascular pain syndromes may benefit from this procedure.

PTSD and Anxiety Disorders

Recent research has explored the role of Stellate Ganglion Block in selected patients with Post-Traumatic Stress Disorder (PTSD), although this remains a specialized indication.

How Does a Stellate Ganglion Block Work?

The sympathetic nervous system can become overactive after injury, surgery, or certain neurological conditions.

This excessive sympathetic activity may cause:

  • Persistent pain

  • Swelling

  • Temperature changes

  • Abnormal sweating

  • Reduced blood circulation

A Stellate Ganglion Block temporarily interrupts these abnormal nerve signals, allowing the affected tissues and nervous system to recover.

Patients often experience:

  • Reduced pain

  • Improved blood flow

  • Warmth in the affected limb

  • Improved movement

  • Better participation in physiotherapy

Ultrasound-Guided Stellate Ganglion Block

What is Ultrasound Guidance?

Ultrasound-guided Stellate Ganglion Block uses real-time ultrasound imaging to visualize important anatomical structures during the procedure.

The physician can directly identify:

  • Carotid artery

  • Internal jugular vein

  • Thyroid gland

  • Esophagus

  • Longus colli muscle

  • Stellate ganglion region

Advantages of Ultrasound-Guided Stellate Ganglion Block

  • No radiation exposure

  • Real-time visualization of soft tissues

  • Precise needle placement

  • Reduced risk of vascular puncture

  • Enhanced safety profile

  • Ability to observe spread of medication

At Samobathi Pain Clinic, ultrasound guidance is frequently used because of its excellent safety and accuracy.

Fluoroscopy-Guided Stellate Ganglion Block

What is Fluoroscopy Guidance?

Fluoroscopy uses real-time X-ray imaging to guide needle placement during the procedure.

The physician identifies the bony landmarks of the cervical spine and positions the needle accurately near the stellate ganglion before administering the medication.

Advantages of Fluoroscopy-Guided Stellate Ganglion Block

  • Excellent visualization of cervical vertebral anatomy

  • Precise needle positioning

  • Contrast dye confirmation of spread

  • Widely established technique

  • Useful in selected complex cases

Fluoroscopy-guided Stellate Ganglion Block remains an important and reliable technique in interventional pain management.

Which is Better: Ultrasound or Fluoroscopy Guided Stellate Ganglion Block?

Both techniques are effective when performed by experienced pain physicians.

Ultrasound Guidance Offers:

  • No radiation

  • Direct visualization of blood vessels and soft tissues

  • Real-time imaging

Fluoroscopy Guidance Offers:

  • Excellent bony landmark visualization

  • Contrast confirmation

  • Established procedural accuracy

The choice depends on:

  • Patient anatomy

  • Underlying condition

  • Previous surgeries

  • Physician preference

  • Clinical requirements

At Samobathi Pain Clinic, we select the most appropriate guidance technique for each individual patient.

What Happens During the Procedure?

The procedure is usually performed as a daycare treatment.

Before the Procedure

  • Medical history is reviewed

  • Current medications are assessed

  • Informed consent is obtained

During the Procedure

  • The patient lies comfortably on the procedure table

  • The neck is cleaned with antiseptic solution

  • Local anesthesia is administered

  • Needle placement is performed under ultrasound or fluoroscopic guidance

  • Medication is injected around the stellate ganglion

The procedure typically takes 10–20 minutes.

What is Horner's Syndrome?

After a successful Stellate Ganglion Block, patients may temporarily develop:

  • Drooping of the eyelid

  • Smaller pupil

  • Mild redness of the eye

This is called Horner's Syndrome and is an expected temporary effect that indicates successful sympathetic blockade.

The symptoms usually resolve within a few hours.

Is Stellate Ganglion Block Painful?

Most patients tolerate the procedure very well.

Only mild discomfort may be experienced during needle insertion. Local anesthesia is used to maximize comfort during the procedure.

What are the Risks of Stellate Ganglion Block?

Although generally safe, potential risks include:

  • Temporary hoarseness of voice

  • Difficulty swallowing

  • Bruising

  • Infection

  • Bleeding

  • Temporary Horner's Syndrome

  • Rare nerve injury

Image-guided techniques significantly improve safety.

How Long Does Pain Relief Last?

The duration of relief varies depending on the underlying condition.

Some patients experience relief for weeks or months after a single injection, while others may require a series of blocks combined with rehabilitation and physiotherapy.
