Each year, over 550,000 patients in the U.S. alone will undergo procedures where arteries or veins are surgically connected (anastomosis). These procedures are performed in reconstructive, transplant and vascular surgery. Invariably, there is a risk of a clot (thrombosis) forming in the newly connected vessels during the postoperative period. Detecting clot formation in a rapid manner allows intervention to remove the clot before it permanently blocks the vessels and is key to preventing catastrophic and costly surgical failures. Ultrasound is ideal for vascular monitoring — but only if simplified for non-expert users. To make postoperative vascular monitoring by non-sonographers a reality, Sonavex is developing the EchoSure system – a Doppler ultrasound system that automatically detects flow loss.
