The Seldinger Sequence – Interventional Radiology T-Shirt

ACCESS IS EVERYTHING.

A clean technical tribute to the four steps that changed vascular access forever: needle, guidewire, needle removal and catheter advancement.

The minimalist four-panel illustration tracks the signal-cyan guidewire through the Seldinger sequence—an instantly recognisable visual for interventional radiologists, radiology residents and everyone who works with wires and catheters.

• Material: Premium 95% cotton and 5% elastane blend

• Fit: Comfortable unisex silhouette with natural stretch

• Design: Minimal two-colour technical line art

• Ideal for: Hospital wear, conferences, casual outings or gifting

• Care: Machine wash cold and tumble dry low. Do not iron directly over the print.

The story behind the design — April 1952

Sven-Ivar Seldinger, a radiologist in his early thirties at the Karolinska in Stockholm, had spent months trying to get a catheter into an artery without cutting down onto it. Then, by his own account, came “a sudden attack of common sense” and he knew what to do: needle in, guide-wire in through the needle, needle out, catheter in over the wire, and finally removal of the guide-wire.

He published it in 1953. Seventy years on, it is still the first thing you do in every case you will ever perform — and the step that, done badly, ends the case before it starts.
