In 1952, Swedish radiologist Sven-Ivar Seldinger was a newly practicing radiologist at Stockholm’s Karolinska Institute. While working at the medical university, the doctor devised one of today’s cornerstones in radiology diagnostics. The catheterization procedure was referred to as the Seldinger technique for years; its use has become so standard, Seldinger’s name is rarely connected to it in medial discussions.

Up until Seldinger’s discovery, radiologists throughout the world had no method that was as low-risk and effective for cardio arteriography, or capturing an image of the heart’s vascular system. In fact, before Seldinger unlocked the puzzle, many procedures common today were high-risk or impossible. The access technique is described as follows: a hollow needle is inserted into a blood vessel and a guide wire pushed through it. The needle is removed and a catheter is placed over the wire, which is subsequently removed. The catheter can then be guided through the vascular “roadway”.

Steven Wengrover, M.D. is a specialist in diagnostic radiology based in New York. A graduate of Albert Einstein College of Medicine of Yeshiva University, Dr. Wengrover has practiced medicine for over thirty years.
