When surgery enters the picture
Community-derivedClinical reference
Surgery is not the starting line for TOS treatment. For neurogenic TOS, the standard-of-care sequence is: a confirmed diagnosis, a trial of TOS-specialized physical therapy (typically 3–6 months), often a diagnostic scalene block, and only then consideration of surgical decompression. For vascular TOS — especially a confirmed blood clot or active positional vascular compression — the path to surgery is faster and more direct.
The clearest community takeaway across 100 surgical posts: surgery works best when it addresses a confirmed, specific compression that conservative care can't resolve. Surgery chosen out of frustration with slow PT progress — without a clear structural target — is the pattern behind the most painful outcomes in the dataset.
The surgical-decision sequence most community members describe
1. Confirmed TOS diagnosis by a specialist.
2. 3–6 months of TOS-specialized PT (not generic PT).
3. For nTOS: a positive diagnostic scalene block — the strongest pre-surgical predictor of success.
4. Imaging that identifies a specific compression site: cervical rib, hypertrophied scalene, pec minor involvement, vascular narrowing.
5. Consultation with a TOS-specialist surgeon — not a general vascular surgeon or general thoracic surgeon who occasionally treats TOS.
The procedures, explained
Clinical referenceCommunity-derived
TOS surgery is not one procedure. It is a family of decompressions, often combined. What the surgeon does depends on where the compression is, which subtype you have, and their training.
First Rib Resection (FRR)
Scalenectomy
Pec Minor Release / Resection
Pec minor release isn't risk-free
One user reports worsened shoulder instability after pec minor release, noting it's a major stabilizing muscle (Post #20). Pre-surgical shoulder imaging matters — a labral tear or rotator cuff issue can worsen when the pec minor is released and should be identified first.
Brachial Plexus Neurolysis
Surgical freeing of the brachial plexus nerves from surrounding scar tissue and adhesions. Typically performed as part of a full decompression (Post #31). Particularly relevant when nerves have become embedded in surrounding tissue or tethered to anatomy — as in Post #3, where C8 and T1 were tethered to the first rib.
Surgical approaches
Clinical referenceCommunity-derived
Three approaches appear in the community data. The choice depends on the surgeon's training, what needs to be accessed, and the TOS subtype.
Transaxillary (through the armpit)
Incision through the armpit. The most traditional approach. The rib is accessed from below. Described in Posts #31, #67, #77. Works well for first rib access but limits simultaneous access to the scalenes and brachial plexus.
Supraclavicular (above the collarbone)
Incision above the collarbone. Allows simultaneous access to the scalenes, brachial plexus, and first rib. Often preferred for nTOS cases where nerve work is central. Described in Post #3.
Robotic
A newer, less invasive technique using robotic instrumentation. One user describes robotic first rib removal with scalenectomy (Post #13). Outcomes data is still accumulating — robotic surgery is promising but should only be done by high-volume TOS surgeons specifically trained in the robotic approach.
What surgeons in the data actually do
Most named TOS specialists in the community (Thompson, Donahue, Freischlag, Johansen) use the supraclavicular approach for nTOS and select the approach for vTOS based on the specific anatomy and whether venous reconstruction is needed. Ask your surgeon which approach they will use and why.
Success rates — vTOS vs. nTOS
Peer-reviewedCommunity-derived
The single most important distinction for setting expectations: vascular and neurogenic TOS have very different surgical response rates. Conflating them is a common source of over- or under-optimism.
Vascular TOS (vTOS)
Neurogenic TOS (nTOS)
Long-term outcome trajectory
Peer-reviewed
Published data reveals a concerning pattern of outcome deterioration over time — information rarely emphasized in surgical consultations.
Sources: Journal of Vascular Surgery; PMC5871990; Royal College of Surgeons review of 17 years experience.
This doesn't mean surgery is a bad choice — it means post-operative maintenance matters. Most of the decline appears driven by scar tissue reformation, unaddressed biomechanical contributors, and return to pre-surgical postural or activity patterns. The community members with sustained long-term outcomes consistently describe ongoing PT, permanent ergonomic adaptations, and strict activity restrictions ("Know the NO's") years after surgery.
Why surgeries fail
Community-derivedPeer-reviewed
Published literature documents a 15–20% recurrence rate after FRR or scalenectomy. The community data corroborates this. Here are the recurring patterns behind the failures in the dataset.
Incomplete decompression
"Just make sure everything gets taken out if you do surgery." Rib cartilage left in place causes immense pain.Post #42
Residual rib cartilage, scar tissue reformation, or failure to address all compression sites. FRR without pec minor release when pec minor is also involved is a classic incomplete-decompression pattern.
Wrong diagnosis
Post #20 describes a patient told they don't have TOS after failed diagnostic injections. Shoulder instability, cervical disc disease, cervical instability, or dorsal scapular nerve entrapment can all mimic TOS. A negative scalene block before surgery should trigger rediagnostic work, not a push to operate anyway.
Scar tissue and adhesion formation
Multiple users report initial improvement followed by gradual regression as scar tissue reforms around the brachial plexus. This is the dominant pattern behind the long-term outcome decline. Post-operative nerve glides and movement are community-credited with keeping adhesions loose.
Unaddressed cervical rib
"My first FRRS went fantastic at first, the mess came later purely due to my cervical rib."Post #95
Initial success undermined by a cervical rib that wasn't addressed. Not all TOS cases involve cervical ribs, but when present, they must be part of the surgical plan.
Biomechanical destabilization
"This surgery crippled me and I am unable to move around without constant pain."Post #72
One of the most negative outcomes in the dataset. Raises the under-discussed concern that ribs are critical to thoracic biomechanics and that removing one can have structural consequences, particularly in patients with hypermobility or connective-tissue disorders.
Surgeon inexperience
Post #74 describes a frightening post-surgical experience. The community is near-unanimous on this: only use surgeons who specialize in TOS (Posts #42, #10). A general vascular surgeon or thoracic surgeon who does TOS "sometimes" is not the same as a high-volume TOS specialist.
Post-surgical complications
Peer-reviewed
Published complication rates from large database reviews provide a realistic baseline. Most are uncommon; a few are common enough to warrant explicit pre-op conversation.
Common (or expected)
- Temporary numbness and paresthesia — nerve manipulation during surgery produces transient neurological symptoms that typically resolve over weeks to months.
- Shoulder stiffness and restricted ROM — common in the first 2–3 months; responds to progressive PT.
- Scar tissue — accumulates over time; the largest contributor to long-term outcome decline.
Less common but significant
- Pneumothorax — collapsed lung during surgery; usually managed intraoperatively.
- Phrenic nerve injury — temporary or permanent diaphragm weakness. Published rate: 3.7% in revision cases.
- Brachial plexus injury — temporary in 0.7% of revisions; permanent injury is rare but devastating.
- Persistent shoulder pain — Post #36: "After rib resection I have [shoulder pain] 24/7 and it's horrible. Didn't have any of that pain prior to surgery."
- Long thoracic nerve injury / scapular winging — see community discussion for the post-op scapular winging patterns.

Choosing a surgeon
Community-derivedPractical tool
This is the single most emphasized variable across the 100 surgical posts. Surgeon selection changes outcomes more than any other decision you will make about this surgery.
Named surgeons with strong community reputation
The following surgeons appear in the dataset with overwhelmingly positive community sentiment. This list is not exhaustive — for a fuller and more current list, tosoutreach.com/find-a-surgeon maintains a surgeon directory with geographic filters.
- Dr. Robert Thompson — now listed with Texas Vascular Associates, with a Baylor Plano clinic location; long-time former Washington University TOS surgeon. Complete resection specialist. Performed aggressive anterior + middle scalenectomy on a severe vTOS case (Post #34).
- Dr. Dean Donahue — MGH. Described by one patient as "phenomenal" and "incredibly thorough." Performed bilateral FRR plus standalone pec minor resection across three surgeries (Post #42).
- Dr. Julie Freischlag — established vascular surgeon with published outcomes data.
- Dr. Kay Johansen — Seattle. Performed two surgeries on the same recurring-TOS patient: "Saved my life twice" (Post #42).
- Dr. Greg Pearl — Dallas. Frequently mentioned as a TOS specialist in community threads.
- Dr. Apple — Austin. Performed combined FRR + scalenectomy + pec minor release (Posts #31, #39, #42).
What community members screen for
- TOS-specific volume. Ask how many TOS surgeries they do per year and what proportion of their practice is TOS.
- Subtype experience. vTOS, nTOS, and aTOS have different surgical considerations. A surgeon who primarily does vTOS may not be your best choice for nTOS.
- Published outcomes. The named specialists above have peer-reviewed outcomes data.
- Team approach. The best TOS centers have dedicated TOS PTs, pain management, and vascular imaging.
- Willingness to discuss failures. A surgeon who can't or won't discuss their failure rate is a warning sign.
A community-flagged caution about TOS forums and groups
Post #10 warns that some TOS Facebook groups censor negative surgical experiences and may have surgeon-affiliated staff as admins. Post #42 explicitly solicits both good and bad experiences. The Reddit community (r/ThoracicOutletSupport) generally allows more balanced reporting than some of the Facebook groups.
Predictors of success
Peer-reviewedCommunity-derived
Both published data and community experience point to a consistent set of factors that predict whether surgery will help you.
Positive predictors
- Positive diagnostic scalene block. Published data: 63% complete improvement and 35% partial improvement when patients respond to a scalene block before surgery. The block serves as a "surrogate for surgical expectations."
- Classic nTOS symptoms. Post #40: "People who have the best response to surgery are those that have the classic symptoms" — numbness, tingling, weakness, pain in hands/fingers.
- Confirmed vascular pathology. Blood clots, positional vascular compression confirmed on imaging, or visible discoloration all predict a strong surgical response.
- Cervical rib presence. Post #88 observes that nTOS surgery appears much more beneficial for people with cervical ribs. Published data supports this.
- Shorter symptom duration. Earlier intervention correlates with better outcomes across multiple published series.
Negative predictors
- Negative scalene block. Post #20: no reaction to diagnostic injections, later told they don't have TOS. Non-response predicts poor surgical outcome.
- Major depression. Published data identifies depression as a predictor of poor surgical outcome — not because the surgery is different but because chronic pain recovery depends on psychological resources.
- High pre-operative disability scores. DASH score > 50.5 or BPI > 73.5 predict worse outcomes.
- Atypical symptom presentation. Non-classic presentations have lower surgical success rates.
- Unaddressed co-existing pathology. Cervical disc disease, labral tears, or hypermobility/EDS can confound outcomes — see the next section.
Recovery timeline
Peer-reviewedCommunity-derived
Synthesized from community reports and published rehabilitation data. Individual recovery varies widely — these are realistic expectations, not guarantees.
TOS-specialized post-op PT is non-negotiable
Post #73: "Finding a TOS-expert PT is the most important variable." Post #94: "PT exasperated and made worse issues after surgery" when not specialized. Published standard: 2 months PT minimum; nTOS patients require median 4 months before symptom-free. Ask your surgeon for their PT referral before surgery and confirm the PT has handled TOS post-ops specifically.
When surgery doesn't fully resolve symptoms
Community-derivedPeer-reviewed
One of the most practically useful threads in the data is what community members with partial recoveries did next. Surgery rarely being a clean "before and after" is part of why this page exists — many people improve significantly and still have residual work to do.
Revision surgery
Post #55 describes revision FRR + scalenectomy at 18 months post initial surgery, with significant improvement after the second procedure. Dr. Kay Johansen performed two surgeries for a recurring-TOS patient — described as "life-saving both times" (Post #42). Published data: revision surgery has 84% success at 3 months but declines to 41% at 10–15 years. Temporary plexus injury occurs in 0.7% of revisions; phrenic palsy in 3.7%.
Post-surgical physical therapy
See the recovery section. TOS-specialized PT is the most commonly credited intervention for residual symptoms. Post #57 describes continuing scalene and scapular rehab post-operatively for months.
Medications for residual symptoms
Post #88 describes halving gabapentin dose 11 months post-surgery — still needed but less. Post #100 uses pregabalin for ongoing partial-recovery management. Muscle relaxants for post-surgical spasm and new scar-tissue tension patterns are common. See the medications page for the full picture.
Continued exercise-based work
Even post-surgery, the underlying muscular imbalances that contributed to TOS often persist. Serratus and scapular work, pec minor release, and nerve glides remain relevant — the conservative treatment page covers the mechanics in detail.
Permanent lifestyle modifications
"Know the NO's. Stick to them always or regret."Post #42 (Dr. Johansen's patient)
Strict activity restrictions emerge as a common feature of sustained long-term recovery. Workstation modifications (split keyboards, vertical mice, dictation software, arm rests) are reported as permanent by many post-surgical community members (Posts #61, #91). Mental health support is specifically recommended for the anxiety and depression that can arise from chronic pain cycles (Post #82).
Co-existing conditions to screen for
Community-derivedPeer-reviewed
Several conditions either mimic TOS or co-exist with it and substantially change surgical outcomes. Pre-surgical workup should explicitly address these.
- Cervical disc disease. Posts #20, #35: multiple users have overlapping cervical compression. Cervical MRI is repeatedly emphasized before TOS surgery.
- Shoulder instability / labral tears. Can mimic TOS or co-exist. Must be identified before pec minor release, which can worsen pre-existing instability (Post #20).
- Dorsal scapular nerve entrapment. Post #98, plus published data from China: common alongside TOS. Surgeons need to address DSN entrapment to clear all pain. Duloxetine specifically helped one 12+ year sufferer.
- Ehlers-Danlos Syndrome / hypermobility. Posts #71, #72: connective tissue disorders complicate TOS surgery outcomes. Some surgeons note that PT alone won't be sufficient, but the hypermobile population also appears over-represented in negative surgical outcomes — see the EDS discussion.
- Cervical instability. See the cervical-instability section — relevant to surgical risk assessment and to Botox safety.
- POTS / dysautonomia. Often co-exists with nTOS, particularly in hypermobile patients. See the POTS section.
Questions to ask your surgeon
Practical tool
- How many TOS surgeries do you do per year? What proportion of your practice is TOS?
- Do you have published outcomes data? What is your complication rate?
- Based on my imaging and clinical findings, what specific compression site(s) are we addressing? What procedure(s) do you propose?
- Which surgical approach (transaxillary, supraclavicular, robotic) are you using and why?
- Have I had a diagnostic scalene block? If not, should I have one before surgery?
- Have we ruled out cervical disc disease, shoulder instability, and other mimics with appropriate imaging?
- For nTOS: what is your realistic expected success rate for a patient with my presentation?
- Who will be my post-operative PT, and do they have specific experience with TOS post-ops?
- What activity restrictions will I have — for the first 6 weeks, 6 months, and long-term?
- What is your revision rate, and what factors predict the need for revision surgery?
- For hypermobile or EDS patients: How does my connective tissue status change your approach, and what does success look like in this population?
