Where May-Thurner, nutcracker, pelvic congestion and SMA syndrome are treated
These conditions are uncommon, and many doctors see only a few cases. A practical way to find experience is to look at which hospitals publish on them. We went through the author affiliations of every PubMed paper on each condition and counted, for every hospital, how many papers its doctors wrote. Choose a condition below, then filter by state.
How to use these lists
- A hospital with many publications has doctors who study the condition. It is a sign of experience, not proof of better care.
- The number in each row opens exactly those papers in PubMed, so you can see what the hospital published and when.
- Recent papers matter more: the "Years" column shows the first and the latest publication.
- Many good doctors treat these conditions without publishing. Ask any doctor how many patients with your condition they treat each year.
May-Thurner syndrome (iliac vein compression)
Usually treated by vascular surgeons and interventional radiologists who place venous stents. See also stent results from every published study.

Source: author affiliations in 1277 PubMed records on SMA syndrome, built November 9, 2026. A hospital is counted once per paper if any author listed it. Publications show research activity, not the number of patients treated or the quality of care; this list is not an endorsement or a ranking.
How we built these lists
- We downloaded every PubMed record on each condition and read the affiliation of every author.
- A hospital counts once per paper, however many of its doctors are authors. Different spellings of the same hospital are merged; departments are merged into their hospital.
- US hospitals are listed when they have at least 2 papers and a known state; outside the US we show the hospitals with the most papers.
- We list institutions only, never the names of individual doctors.
Limitations
- Publishing reflects research interest, not the number of patients treated or the results of care.
- Affiliations are written in many ways, so some hospitals may be split, merged or missing.
- Some papers are single case reports; the "studies or series" column counts only papers that are not case reports.
- This list is not an endorsement or a ranking, and we have no financial relationship with any hospital.
