Stent grafts: a better way to treat blunt traum...(omposed of fabric supported by a metal m...)

omposed of fabric supported by a metal mesh) through the blood vessels. When expanded within the artery, the stent graft bridges the injury, reinforcing an artery's weak spot (the tear), and when successful, eliminates the risk of continued expansion and rupture, said Hoffer. This advance in treatment provides a less invasive option with less pain, less recovery time and a lower risk of complications than open surgery.

Researchers systematically reviewed 50 reports with 722 endovascular repairs for this study, published in the Journal of Vascular and Interventional Radiology (JVIR), the official journal of the Society of Interventional Radiology. According to the study, the "endovascular advantage" was demonstrated in relation to contemporary intensive care and surgical methods, which over the past 30 years decreased operative mortality rates from 45?? percent to 18?? percent. Endograft repair further reduced mortality to 8?? percent. The improved survival rate "may be a result of the decreased systemic stress that endovascular repair affords," said Hoffer," which is important with this group of patients where additional severe injuries are common."

Interventional radiologists, working in multidisciplinary teams with cardiothoracic surgeons and vascular surgeons, pioneered the application of the stent-covered graft for blunt trauma injuries, said Hoffer. Interventional radiologists introduced the idea of taking off-the-shelf stents and vascular graft material to combine them into handmade stent grafts, using these devices to repair lesions from within a blood vessel. This year, SIR celebrates 35 years of quality patient care innovation. "This study provides another indication of the tremendous innovation in the development of new devices and techniques that interventional radiology continues to offer," said Hoffer.
