Percutaneous Tracheostomy and Percutaneous Angiography: The Diuturnity of Sven-Ivar Seldinger of Mora, Pasquale Ciaglia of Utica.

In the latter part of the 20th century, three developments intersected: skin-to-artery catheterization, percutaneous tracheostomy, and market introduction of video-chip camera-tipped endoscopes. By the millennium, every vessel within the body could be visualized radiographically, and percutaneous tracheostomy (with tracheal-ring "dilation," flawless high-resolution intratracheal video-imagery, and tracheal intubation) could consistently be achieved at the patient's bedside. Initiated through the skin and abetted by guide-wire insertion, these procedures are the lasting gifts of Sven-Ivar Seldinger (1921-1998) of Mora, Sweden, and Pasquale Ciaglia (1912-2000) of Utica, New York. Physicians and surgeons managing intracranial, craniofacial, and maxillofacial injury are among those honoring the Seldinger-Ciaglia "collaboration."
