Flow measurement offers potential to reduce microvascular complications.

Plastic, reconstructive and hand surgeons now have access to a precision flow measurement tool to intraoperatively assess anastomotic patency in microvascular and lymphatic vessels. Engineering innovations by Transonic Systems, the leader in transit-time flow measurement, now allow their newest Flowmeter, the Optima®, to measure flows as low as 0.1 mL/min, in vessels as small as 0.5 mm.

The Optima® meter and its companion new microsurgical flowprobe line provide immediate, quantitative flow measurements to help the surgeon detect and correct otherwise undetectable flow restrictions – critical in procedures where flow restoration is key to a successful outcome. A study by Selber et al, from The University of Texas MD Anderson Cancer Center, concluded that transit-time flow volume “provides novel physiologic flap data and identifies flawed anastomoses...These data have clinical value in microsurgery and hold the potential to reduce microvascular complications and improve outcomes.”¹

On this achievement, Transonic founder Cor Drost notes, “Cardiac, cerebrovascular and transplant surgeons have relied on transit-time flow measurements to determine vessel patency for years – we are extremely excited to now be able to bring this unprecedented measurement resolution capability to surgeons who are performing very complicated microvascular procedures.”

About Transonic: Transonic Systems Inc. is a global manufacturer of innovative biomedical measurement equipment. Founded in 1983, Transonic sells gold standard transit-time ultrasound flowmeters and monitors for surgical, hemodialysis, critical care, perfusion, interventional radiology and research applications.
