Draft Response to Maria Rios

Subject: Re: Inquiry about Tangdu Hospital 3D-Printed Extravascular Stent Treatment

Dear Maria,

Thank you for reaching out to us, and for the detailed introduction about your condition. We have read your message carefully and have taken the time to review the research paper you referenced (He et al., Frontiers in Bioengineering and Biotechnology, 2020) on the 3D-printed PEEK extravascular stent developed at Tangdu Hospital.

You are absolutely right — this is a remarkably innovative approach. The ability to custom-print an external stent that respects the natural anatomy of the left renal vein, while avoiding the complications associated with intravascular stenting, represents a significant advancement in the treatment of Nutcracker Syndrome. We also understand that the anchoring design addresses one of the key challenges with extravascular stents — migration.

What we can help with:

We work directly with Tangdu Hospital's International Department to coordinate care for international patients. Our services include:

• Remote specialist consultation — Your existing imaging (CT, MRI, or ultrasound) can be reviewed by Tangdu's vascular team to confirm candidacy for the procedure
• Cost estimation & treatment planning — A detailed breakdown of procedure costs, hospital stay, and follow-up
• Medical visa invitation letter — Required for entry into China
• Travel & accommodation coordination — Airport pickup, hospital transfer, accommodation near the hospital
• On-the-ground support — English-speaking assistance during your stay in Xi'an

To help us move forward, we would appreciate a few more details:

1. Diagnostic imaging — Do you have recent CT, MRI, or ultrasound results showing the compression of your left renal vein and/or iliac vein? These would be needed for Tangdu's specialists to evaluate your suitability.
2. Current symptoms — How long have you been experiencing symptoms, and how significantly do they impact your daily life? (Pain level, kidney function, any complications such as hematuria or proteinuria?)
3. Previous treatments — Have you tried any treatments before (medication, stenting, other surgeries)?
4. May Thurner component — Have you had any imaging specifically for the iliac vein compression? Do you have symptoms on that side as well (leg swelling, DVT history)?
5. Age & general health — Just so we can assess suitability for the procedure.
6. Insurance — Do you have health insurance that may cover international treatment?
7. Timeline — Do you have a preferred timeframe for seeking treatment?

We understand these are personal questions, but they will help us give you accurate guidance and connect you directly with the right specialist at Tangdu.

In the meantime, please feel free to ask any questions you may have about the process, costs, or what to expect. We are here to help.

Looking forward to hearing from you.

Warm regards,
